Agrawal SS; Rajagopal K. Nicotine contents in various toothpowders (dant manjans): Measurement and safety evaluation. Food and Chemical Toxicology 47(3): 511-524, 2009. (24 refs.)

The use of tobacco products as dentrifice is prevalent in various parts of India. Among them toothpowder (dant manjan) is very common. These nicotine containing toothpastes/tooth powders are health hazards and is also habit forming. Health experts of India rightly banned use of nicotine containing toothpowder as early as 1992 by making proper legislation. We just made an attempt to verify whether the manufacturers complying the legislation or not. Eight leading brands of toothpowders were analyzed qualitatively by gas chromatography-mass spectrum detector and also quantitatively by gas chromatography-nitrogen phosphorus detector. Our results indicated four brands were found to contain nicotine in the range of 2.53 mu g/g to 11.50 mg/g of toothpowder. This finding further confirms that addition of nicotine in dentifrice violates the regulatory norms. Regulatory authorities should give more attention to ensure that all toothpowders are free from nicotine which is also a statutory requirement.

Aitken CK; Fry TRL; Farrell L; Pellegrini B. Smokers of illicit tobacco report significantly worse health than other smokers. Nicotine & Tobacco Research 11(8): 996-1001, 2009. (34 refs.)

Introduction: The aim of this study was to ascertain whether the health of past and current smokers of illicit tobacco (chop-chop) differs from that of smokers of licit tobacco. Methods: The design was a telephone survey, stratified by state, using computer aided telephone interviewing, with households selected by random digit dialing from the telephone white pages. Setting was all Australian states and territories, 1,621 regular tobacco smokers aged 18+ years. Measures were social and personal characteristics of tobacco smokers, smoking histories and patterns, and health status (SF-8 and disability weights). Binary logistic regression was used to identify variables associated with current and lifetime chop-chop use. Results: Compared with licit-only tobacco smokers, current users of chop-chop had significantly greater odds of beginning smoking aged <16 years (odds ratio [OR] 1.65, 95% CI = 1.09-2.50), of reporting below-average social functioning (OR 1.61, 95% CI = 1.06-2.44), and of a measurable disability (OR 1.95, 95% CI = 1.08-3.51). Lifetime chop-chop users were relatively likely to be less than 45 years of age (OR 1.82, 95% CI = 1.38 2.39), report below-average mental health (OR 1.61, 95% CI = 1.22-2.13) and above-average bodily pain (OR 1.40, 95% CI = 1.06-1.85), smoke more than 120 cigarettes/week (OR 1.39, 95% CI = 1.06-1.83), and to have begun smoking aged < 16 years (OR 1.33, 95% CI = 1.01-1.75). Discussion: Current and lifetime users of chop-chop report significantly worse health than smokers of licit tobacco. Investigation of how to communicate this finding to current and potential chop-chop smokers is warranted.

Brunt TM; Rigter S; Hoek J; Vogels N; van Dijk P; Niesink RJM. An analysis of cocaine powder in the Netherlands: Content and health hazards due to adulterants. Addiction 104(5): 798-805, 2009. (38 refs.)

Aims: To report on trends in the content and adulterants present in street cocaine ( powder) in the Netherlands and to describe the associated health hazards. Design and participants Drug consumers handed in samples of cocaine powder from 1999 to 2007 for analysis. Reports were compiled of users' experiences with the samples received. Measurements and analysis Linear regression analysis was used to assess the trend in adulterated cocaine powder across the study period, and comparison of reported adverse effects of adulterated with those of unadulterated cocaine by Fisher's exact test. Findings There has been a statistically significant upward trend in the occurrence of adulterated cocaine powder over the years. Adulterated cocaine was associated more frequently with reported adverse effects than unadulterated cocaine. Phenacetin, hydroxyzine and diltiazem appeared to be three adulterants contributing to these adverse effects. Conclusions An increase in adulterants was detected in the analysed cocaine powder between 1999 and 2007. This increase is associated with relatively more adverse effects with cocaine use. The cardiac and hallucinatory effects that were reported more frequently are not understood clearly. Adverse effects are likely to be due to several factors, including interactions of adulterants with cocaine and the route of administration.

Cox LA. Could removing arsenic from tobacco smoke significantly reduce smoker risks of lung cancer? Risk Analysis 29(1): 3-17, 2009. (61 refs.)

If a specific biological mechanism could be determined by which a carcinogen increases lung cancer risk, how might this knowledge be used to improve risk assessment ? To explore this issue, we assume (perhaps incorrectly) that arsenic in cigarette smoke increases lung cancer risk by hypermethylating the promoter region of gene p16INK4a, leading to a more rapid entry of altered (initiated) cells into a clonal expansion phase. The potential impact on lung cancer of removing arsenic is then quantified using a three-stage version of a multistage clonal expansion (MSCE) model. This refines the usual two-stage clonal expansion (TSCE) model of carcinogenesis by resolving its intermediate or "initiated" cell compartment into two subcompartments, representing experimentally observed "patch" and "field" cells. This refinement allows p16 methylation effects to be represented as speeding transitions of cells from the patch state to the clonally expanding field state. Given these assumptions, removing arsenic might greatly reduce the number of nonsmall cell lung cancer cells (NSCLCs) produced in smokers, by up to two-thirds, depending on the fraction (between 0 and 1) of the smoking-induced increase in the patch-to-field transition rate prevented if arsenic were removed. At present, this fraction is unknown (and could be as low as zero), but the possibility that it could be high (close to 1) cannot be ruled out without further data.

Cunningham JK; Liu LM; Callaghan R. Impact of US and Canadian precursor regulation on methamphetamine purity in the United States. Addiction 104(3): 441-453, 2009. (62 refs.)

Reducing drug purity is a major, but largely unstudied, goal of drug suppression. This study examines whether US methamphetamine purity was impacted by the suppression policy of US and Canadian precursor chemical regulation. Autoregressive integrated moving average (ARIMA)-intervention time-series analysis. Continental United States and Hawaii (1985-May 2005). US federal regulations targeting precursors, ephedrine and pseudoephedrine, in forms used by large-scale producers were implemented in November 1989, August 1995 and October 1997. US regulations targeting precursors in forms used by small-scale producers (e.g. over-the-counter medications) were implemented in October 1996 and October 2001. Canada implemented federal precursor regulations in January 2003 and July 2003 and an essential chemical (e.g. acetone) regulation in January 2004. Monthly median methamphetamine purity series. US regulations targeting large-scale producers were associated with purity declines of 16-67 points; those targeting small-scale producers had little or no impact. Canada's precursor regulations were associated with purity increases of 13-15 points, while its essential chemical regulation was associated with a 13-point decrease. Hawaii's purity was consistently high, and appeared to vary little with the 1990s/2000s regulations. US precursor regulations targeting large-scale producers were associated with substantial decreases in continental US methamphetamine purity, while regulations targeting over-the-counter medications had little or no impact. Canada's essential chemical regulation was also associated with a decrease in continental US purity. However, Canada's precursor regulations were associated with purity increases: these regulations may have impacted primarily producers of lower-quality methamphetamine, leaving higher-purity methamphetamine on the market by default. Hawaii's well-known preference for 'ice' (high-purity methamphetamine) may have helped to constrain purity there to a high, attenuated range, possibly limiting its sensitivity to precursor regulation.

Davies S; Wood DM; Smith G; Button J; Ramsey J; Archer R et al. Purchasing 'legal highs' on the Internet-is there consistency in what you get? QJM-An International Journal of Medicine 103(7): 489-493, 2010. (15 refs.)

Background: The supply of recreational drugs has changed and users increasingly buy 'legal highs' over the Internet. Use of these is common and there is a potential for significant toxicity associated with their use. Aim: To determine the content of legal highs available for purchase in the UK and whether the content of these remains consistent. Methods: Twenty-six legal highs were purchased monthly from five different Internet sites over 6 months. These were analysed to determine the drugs in the products and whether there were any changes in their content over this time period. Results: All products were supplied initially, but there was a decline in supply of products month by month. The following drug classes were detected: piperazines, cathinones, caffeine/ephedrine or products in which no psychoactive drugs were detected. Of the products supplied on more than one occasion, 15 (75%) contained the same compounds on each occasion. In three products there was a change in the piperazine detected, with 1-benzylpiperazine being substituted for 1-methyl-4-benzylpiperazine or vice versa. In two other products there was a cathinone [4-fluorophenylpiperazine (pFPP) or 3-fluromethcathinone (3FMC)] detected in products purchased in Month 1 that was not present in the products purchased in subsequent months. Conclusions: Whilst there was no variation in the composition of most legal highs supplied over 6 month, there was significant variation in the piperazine or cathinone content of one quarter of the products. This variation could be of clinical significance as the cathinone and piperazine products can be associated with significant toxicity.

Dettmeyer RB; Verhoff MA; Bruckel B; Walter D. Widespread pulmonary granulomatosis following long time intravenous drug abuse-A case report. Forensic Science International 19(1-3): E27-E30, 2010. (22 refs.)

Foreign body granulomas in the lungs following acute singular or long time intravenous drug abuse are frequent findings during microscopic investigation of the lungs. Most cases present single granulomas. Cases with multiple foreign body granulomas, already palpable during autopsy and leading to pulmonary granulomatosis with multiple granulomas are less frequent. We report the case of a 32-year old man, dying suddenly and unexpectedly after a well-known history of drug abuse for more than a decade. The granulomas are caused by foreign particle embolization immediately after intravenous injection of not only the drug itself but also of adulterants, e. g. cotton fibers, potato starch or microcrystalline cellulose. At the end, a reduction in the size of the pulmonary bed had occurred followed by pulmonary hypertension. For the first time, lung dust in such a case was characterised by energy dispersive X-ray (EDX).

Donike M. The detection of doping by means of chromatographic methods. Drug Testing and Analysis 3(1): 15-17, 2011. (14 refs.)

This article was first published in German in Der Sportarzt, 1966, 2, 81-84 as Der Dopingnachweis mit Hilfe chromatographischer Methoden. Translated and republished with permission. Doping has become an issue in elite sport and necessitates sensitive detection assays that enable the identification of organic compounds on a microscale level in urine. In agreement with modern toxicological methods, sports drug testing approaches can utilize paper, thin layer or gas chromatographic methods to reveal the presence of prohibited substances such as strychnine, pervitine, captagone, benzedrine etc. in doping control specimens. Basic principles of these strategies are summarized and considerations for future applications discussed.

Duterte M; Jacinto C; Sales P; Murphy S. What's in a label? Ecstasy sellers' perceptions of pill brands. Journal of Psychoactive Drugs 41(1): 27-37, 2009. (45 refs.)

This article presents selected findings from a qualitative study of Ecstasy sellers and their sales practices, knowledge of distribution networks, buyer-seller relationships, and self-reported drug use. In-depth interviews were conducted with 80 men and women who had sold five or more hits of Ecstasy five or more times in the six months prior to the interview. Study participants described their perceptions of the various types of Ecstasy they had distributed or used themselves. The participants had experience with a variety of Ecstasy labels, from the popular "Blue Dolphin" tablets to the powdered form called "Molly." We tracked pill brand mentions on Ecstasy-related websites to compare with interviewees' descriptions of Ecstasy brands. This study examines Ecstasy sellers' ideas about the role of brand names in Ecstasy markets and their relationship to their beliefs about different types of Ecstasy's purity and quality. We demonstrate that considering Ecstasy branding increases our understanding of buyer and seller relationships.

Evrard I; Legleye S; Cadet-Tairou A. Composition, purity and perceived quality of street cocaine in France. International Journal of Drug Policy 21(5): 399-406, 2010. (52 refs.)

Background: There is little knowledge about the composition and cocaine content of street cocaine, nor about what users know about it. Method: 373 cocaine users were face to face interviewed between May and December 2006 about the last sample of cocaine they had consumed and residual amounts of the substances actually used were analysed using gas phase chromatography coupled to mass spectrometry (GC-MS). Users rated the perceived quality of their product ("good", "average", "poor"), its "estimated percentage of cocaine" and any cutting agents it contained. Price, quantity, place of purchase (street, dealer's premise, appointment), mode of administration (sniffing, injection, smoking) and the supposed nature of the sample (natural, synthetic, no distinction ever made) were also reported. Perceived quality was modelled using multivariate multinomial regression. Results: The median cocaine content was 22%. Altogether, 343 samples contained cocaine, among which 75% contained at least one adulterant. The most frequently occurring were phenacetin (54% of the samples), caffeine (17%), paracetamol (14%), diltiazem and lidocaine (11%). Users showed relatively poor discrimination concerning cocaine purity, and only 12% reported at least one of the detected adulterants. The major determinants of their perception of cocaine quality were: place of purchase, natural origin, price per gram, actual cocaine content and mode of administration. Conclusion: The composition of street cocaine is largely unknown to users. Users' perceptions of cocaine quality are based partly on false beliefs and certain administration modes. This may contribute to favouring very risky practices. The effects of adulterants on users' health should be investigated.

Friedman LS. Real-time surveillance of illicit drug overdoses using poison center data. Clinical Toxicology 47(6): 573-579, 2009. (29 refs.)

Background. In early 2006, government and media sources reported that crime syndicates were mixing fentanyl with heroin. This was followed by an increase in heroin overdoses and opiate-related deaths. The most recent fentanyl outbreak illustrated the need for identifying and establishing effective and responsive real-time surveillance tools to monitor drug overdoses in the United States. Objective. In this study, poison call center data from Illinois were evaluated to determine whether the data could have detected the outbreak that occurred in Illinois in early 2006 and whether it could be used for real-time surveillance. Methods. For this analysis, a two-step approach was used to analyze potential heroin-related calls. First, the data were analyzed retrospectively to identify whether any significant temporal shifts occurred, then a prospective analysis was conducted to simulate real-time surveillance. Results. Between 2002 and 2007, there were a total of 1,565 potential heroin-related calls, and the calls increased by 63.6% in 2006 compared to 2005. In the prospective analysis, the principal model would have identified the outbreak in March 2006. Conclusions. If there had been a real-time surveillance program using poison center data, the outbreak would have been identified I month before the initial postmortem reports to the Centers for Disease Control and Prevention at the end of April 2006. Poison center data provide the potential for an earlier warning system than postmortem data sources, because the reports are usually made within hours of the exposure. Poison center data can be effectively used to monitor heroin-related exposures.

Godwin WS; Subha VR; Feroz KM. Po-210 radiation dose due to cigarette smoking. Current Science 98(5): 681-686, 2010. (34 refs.)

The level of Po-210 in eight brands of cigarettes and four brands of bidis popular in and around Nagercoil town was determined to evaluate the annual effective dose. The Po-210 activity in a full cigarette ranged from 32.8 +/- 3.6 to 68.4 +/- 5.9 mBq and from 34.3 +/- 3.5 to 62.9 +/- 5.8 mBq in a bidi. In tobacco, the highest Po-210 content was recorded in the brand C4 (23.0 +/- 1.2 mBq) whereas for bidis it was the highest in the brand B2 (21.1 +/- 1.1 mBq). The activity in mainstream varied from 15.2 +/- 0.75 to 36.8 +/- 2.1 mBq in a cigarette and from 20.7 +/- 3.1 to 39.8 +/- 4.0 mBq in a bidi. With regard to Po-210 activity concentration, not much specificity was noted with respect to the tobacco brand. The data showed a relatively wide range of activity concentration of Po-210 in the different cigarette/bidi brands and even within the same brand. The bidis showed a higher activity when compared to cigarettes. The popular brands concentrated more activity than the fine brands. Smokers who smoke one pack (10 cigarettes/bidis) per day may inhale about 100-300 mBq d(-1) (0.1-0.3 Bq d(-1)) of Po-210. In this study, radiation dose values in the range of 153.5-372.9 mu Sv Y-1 from cigarettes and from 209.2 to 402.7 mu Sv Y-1 from bidis was estimated for the whole body.

Judkins CMG; Teale P; Hall DJ. The role of banned substance residue analysis in the control of dietary supplement contamination. Drug Testing and Analysis 2(9-10): 417-420, 2010. (19 refs.)

The potential for contaminated dietary supplements to result in a failed doping test remains a concern for athletes, trainers, and sporting authorities despite improvements to regulatory guidelines. Previous surveys of readily available supplements confirm that many are contaminated with steroids and stimulants prohibited for use in elite sport. Suggested responses to this issue include the complete avoidance of all supplements. Many athletes, however, use nutritional supplements to achieve effective training and also to ensure that daily nutritional requirements are met (e.g. recommended levels of vitamins and minerals). This ensures that the use of supplements is and will remain the norm for a range of sports. As a result, an alternative approach of rigorous testing of materials destined for use by elite athletes has been introduced in several countries. While the testing of final product for banned substances may help mitigate the problem, it will not help to remove the underlying issue of contamination. In this article we describe an alternative approach that uses appropriate quality assurance procedures backed up by testing to remove sources of contamination. The decrease in the incidence of contamination amongst supplement companies adopting such a system is explained, and contrasted with the relatively high incidences of contamination found in products that are not part of a quality system. These findings are of key importance to both supplement manufacturers and those involved in advising athletes about supplement use.

Kanteres F; Lachenmeier DW; Rehm J. Alcohol in Mayan Guatemala: Consumption, distribution, production and composition of cuxa. Addiction 104(5): 752-759, 2009. (10 refs.)

ims: To describe the consumption, distribution, production and chemical composition of alcohol, including cuxa (pronounced 'coo sha'), in Nahuala, a highland Mayan municipality in Guatemala. Cuxa is a sugarcane-derived spirit, in part produced clandestinely, that has been distributed in the community for several decades. Methods: Key informant interviews with alcohol distributors and consumers, cuxa producers and health professionals, as well as analyses of questionnaires from a sample of 47 spouses who came to the local health centre for problems related to their husband's drinking. Sampling and chemical analysis of cuxa from 12 of 13 identified sales points in the head-town of Nahuala and its nearby settlements ( 10 km radius). Fieldwork was conducted between November 2007 and March 2008. Results: Alcohol consumption was found to be integrated culturally in this community. The overall drinking culture was marked by irregular heavy drinking occasions, especially around market days, with substantial inebriation and health problems, especially among street inhabiting drinkers. Cuxa contributed to these problems, and cuxa drinking was socially stigmatized. Cuxa was produced both clandestinely and industrially, and sold legally by taverns and illegally by clandestine distributors. The alcoholic strength of the samples was typically between 17 and 19% vol.; clandestinely produced cuxa samples showed acetaldehyde contamination. Conclusions: Measures should be taken to reduce the harm associated with alcohol in this community, including efforts to reduce acetaldehyde levels in cuxa.

Khlifi R; Hamza-Chaffai A. Head and neck cancer due to heavy metal exposure via tobacco smoking and professional exposure: A review. Toxicology and Applied Pharmacology 248(2): 71-88, 2010. (338 refs.)

Chronic exposures to heavy metals via tobacco smoking and professional exposure may increase the risk of head and neck cancer, although the epidemiologic evidence is limited by problems of low study power and inadequate adjustment for tobacco and professional exposure use. Numerous scientific reviews have examined the association of various heavy metals exposure with respiratory cancer as well as other cancer types, but few have been published on head and neck cancer. The purpose of this paper, therefore, is to review the head and neck tract cancer-related data on exposure to heavy metals via smoking and working exposure and to study the major mechanisms underlying some toxic metals carcinogenesis.

Knowles L; Buxton JA; Skuridina N; Achebe I; LeGatt D; Fan S et al. Levamisole tainted cocaine causing severe neutropenia in Alberta and British Columbia. (case report). Harm Reduction Journal 6(1): article 30, 2009. (26 refs.)

Background: Five cases of severe neutropenia (neutrophil counts < 0.5 per 109 cells/L) associated with exposure to cocaine and levamisole, an antihelimithic agent no longer available in Canada, were identified in Alberta in 2008. Alberta and British Columbia (BC) public health officials issued an advisory and urged health care professionals to report cases to public health. This paper presents the findings of the public health investigations. Methods: Cases were identified prospectively through reporting by clinicians and a retrospective review of laboratory and medical examiners data from January 1, 2006 to March 31, 2009. Cases were categorized as confirmed, probable or suspect. Only the confirmed and probable cases are included in this paper. Results: We compare cases of severe neutropenia associated with tainted cocaine (NATC) identified in Alberta and BC between January 1, 2008 to March 31, 2009. Of the 42 NATC cases: 23(55%) were from Alberta; 19(45%) were from British Columbia; 57% of these cases reported crack cocaine use (93% of those who identified type of cocaine used); 7% reported using cocaine powder; and the main route of cocaine administration was from smoking (72%). Fifty percent of the NATC cases had multiple episodes of neutropenia associated with cocaine use. Cases typically presented with bacterial/fungal infections and fever. One Alberta NATC case produced anti-neutrophil antibodies, and four were positive for anti-neutrophil cytoplasmic antibody (ANCA). Analysis of two crack pipes and one drug sample obtained from NATC cases confirmed the presence of both cocaine and levamisole. A further 18 cases were identified through the retrospective review of laboratory and medical examiner data in Alberta. Interpretation: Our findings support a link between neutropenia and levamisole tainted cocaine; particularly from smoking the crack form of cocaine. Some patients may be genetically predisposed to develop levamisole-related neutropenia. Awareness of the differential diagnosis will assist clinicians with case timely detection and appropriate management.

Knox D; Murray G; Millar M; Hamilton D; Connor M; Ferdinand RD et al. Subcutaneous anthrax in three intravenous drug users: A new clinical diagnosis. Journal of Bone and Joint Surgery-British Volume 93B(3): 414-417, 2011. (11 refs.)

Anthrax is extremely rare in the western world but is endemic to areas of south and central Asia. In early 2010 an outbreak was identified in heroin-injecting intravenous drug users in the United Kingdom and Europe. Afghanistan is currently the principal source of heroin which reaches the United Kingdom. When anthrax occurs, cutaneous disease accounts for over 95% of cases. At least 47 cases with 13 deaths have been confirmed so far. We present three cases presenting during this time with marked swelling, one resulting in compartment syndrome but all with an absence of the expected cutaneous appearances. We suggest that rather than cutaneous anthrax, these patients represent a new subcutaneous presentation of anthrax.

Koushesh HR; Afshari R. A new illicit opioid dependence outbreak, evidence for a combination of opioids and steroids. Drug and Chemical Toxicology 32(2): 114-119, 2009. (23 refs.)

Opioid abuse is common in Iran. In 2005, a new version of locally produced illicit opioid vials, so called Norgesic, appeared in the illicit market, which gained popularity rapidly and led to an improvement of stigmatizing the general appearance of dependent cases. Later, some cases suffered Cushing's-like problems. A prospective case series was designed to evaluate 18 Norgesic-dependent subjects who volunteered for abstinence therapy in a rehabilitation clinic from November 1, 2005, to December 30, 2005. In this study, we aimed to describe the clinical and paraclinical findings in detail and define the potential determinants of this Cushing's syndrome outbreak. History, physical examination, plasma cortisol level, and urine screen tests were used to describe the patients. All subjects were male with a mean (SEM) age of 29.8 +/- 1.6 years. The opioid-dependence period was 8.4 +/- 0.9 years. In an average of 4.7 +/- 0.3 months, subjects increased their usage to 5.5 +/- 0.5 vials a day. Patients claimed to gain weight. Striae were seen in 38.9%, previously documented psychological problems in 33.3%, weakness in 27.8%, high systolic blood pressure in 22.2%, moon face in 16.7%, hirsutism in 11.1%, extensive dermal infection in 11.1%, gynecomastia in 5.6%, back pain in 5.6%, insomnia in 5.6%, and lack of potency in 5.6%. Their cortisol level, on average, was 4.8 +/- 1.1 mu g/dL. Hepatitis C virus was positive in 22.2%. Urine-screening tests were positive for morphine and negative for buprenorphine. In conclusion, these new vials contain steroids as well as opioids. This combination could be more dangerous than opioids themselves.

Kowalski R; Wiercinski J. Mercury content in smoke and tobacco from selected cigarette brands. Ecological Chemistry and Engineering 16(2): 155-162, 2009. (13 refs.)

The study aimed at evaluating the total mercury content in tobacco and smoke released from selected cigarette brands. "Mechanical lips" were applied for determining the mercury concentration in cigarette smoke, and its level was calculated by balancing it in tobacco, ash, and cigarette filter. Analyses were made using mercury analyser AMA-254. The study material consisted of selected-brands cigarettes grouped according to tar and nicotine substances contents declared by a producer: 3 brands (L1, L2, and L3) filled with low-tar and low-nicotine tobacco (4 and 0.3 mg/cigarette); 5 brands (M1, M2, M3, M4, and M5) characterized by medium tar and medium nicotine contents (6 divided by 8 and 0.5 divided by 0.6 mg/cigarette), and two remaining brands (S1, S2) with high-tar and high-nicotine levels (12 and 1.0 mg/cigarette). Mercury contents in tobacco from tested cigarette brands ranged from 2.95 to 10.2 ng Hg per a single cigarette. Almost all mercury contained was released to the smoke (from 86.7 to 100%). Cigarette filters made of cellulose acetate appeared to be insufficient barrier for volatile mercury. In some cases, release of mercury from the filter into the smoke was observed. The element content in the filter was higher after than before smoking the cigarette for most brands; however, these were similar values to the metal content before smoking out. Applied filter filled with activated charcoal (single cigarette brand) contained the same amount of mercury before and after smoking the cigarette. Considering 20 smoked cigarettes as daily mean value for an individual person, it can be stated that it is a serious mercury source which supplies the smoker with a dose of 60 divided by 200 ng of the toxic element into his/her lungs every day.

Lachenmeier DW; Kanteres F; Kuballa T; Lopez MG; Rehm J. Ethyl carbamate in alcoholic beverages from Mexico (tequila, mezcal, bacanora, sotol) and cuatemala (Cuxa): Market survey and risk assessment. International Journal of Environmental Research and Public Health 6(1): 349-360, 2009. (40 refs.)

Ethyl carbamate (EC) is a recognized genotoxic carcinogen, with widespread occurrence in fermented foods and beverages. No data on its occurrence in alcoholic beverages from Mexico or Central America is available. Samples of agave spirits including tequila, mezcal, bacanora and sotol (n=110), and of the sugarcane spirit cuxa (n=16) were purchased in Mexico and Guatemala, respectively, and analyzed for EC. The incidence of EC contamination was higher in Mexico than in Guatemala, however, concentrations were below international guideline levels (< 0.15 mg/L). Risk assessment found the Margin of Exposure (MOE) in line with that of European spirits. It is therefore unlikely that EC plays a role in high rates of liver cirrhosis reported in Mexico.

Lachenmeier DW; Samokhvalov AV; Leitz J; Schoeberl K; Kuballa T; Linskiy IV et al. The composition of unrecorded alcohol from eastern Ukraine: Is there a toxicological concern beyond ethanol alone? Food and Chemical Toxicology 48(10): 2842-2847, 2010. (51 refs.)

In 2005, approximately half of all alcohol consumption in Ukraine was unrecorded. This paper investigates the chemical composition of unrecorded and low-cost alcohol, including a toxicological evaluation. A sample of alcohol products (n = 78) from both recorded and unrecorded sources was obtained mainly from eastern Ukraine, and chemically analyzed. entailed alcoholic strength, levels of volatile compounds (methanol, acetaldehyde, higher alcohols), ethyl carbamate, anions, and inorganic elements. The majority of unrecorded alcohol was homemade samohon with alcoholic strength averaging close to 40% vol. A limited number of samples, advertised for medicinal purposes, were identified with high alcoholic strengths (above 60% vol.). Single samples showed contamination with acetaldehyde and ethyl carbamate above the levels of toxicological concern. Metal contamination was frequent, with copper levels above 2 mg/l in 33 samples, and zinc above 5 mg/l in 10 samples. Overall, however, the composition of unrecorded samples did not raise major public health concerns other those for ethanol. The priority of alcohol policy in Ukraine should be the general reduction of alcohol consumption with a specific focus on that from small-scale home production. Further research is needed on potential mitigative measures and the origin of the metal contamination in particular alcoholic beverages.

Lachenmeier DW; Sarsh B; Rehm J. The composition of alcohol products from markets in Lithuania and Hungary, and potential health consequences: A pilot study. Alcohol and Alcoholism 44(1): 93-102, 2009. (42 refs.)

Aims: The rates of alcohol-attributable mortality in Lithuania and Hungary have been shown to be higher than those in most other European countries. Quality of alcohol products is investigated as a possible explanation. Methods: In a descriptive pilot study, a convenience sample of alcohol products was collected from local city markets in both countries (Lithuania n = 10, Hungary n = 15) and chemical analyses, including some that have not been done in prior studies, were conducted. The parameters studied were alcoholic strength, volatiles (methanol, acetaldehyde, higher alcohols), ethyl carbamate, anions (including nitrate) and inorganic elements (including lead). Additionally, a multi-target screening analysis for toxicologically relevant substances was conducted. Results: The majority of samples (64%) had an alcohol content between 35% vol. and 40% vol., being in accordance with the typical strength of legal spirits in Europe. Three samples containing significantly higher concentrations of alcohol above 60% vol. were found to be unrecorded alcohol products, defined as any alcohol that is outside of legal and taxed production. Screening analysis showed that those samples contained various flavourings, including the hepatotoxic substance coumarin, at concentrations above the legal limit for foods. All other substance classes under study were found to be at levels of no toxicological concern. Conclusions: Although some problems with the quality of the alcohol samples were found, there is insufficient evidence from this pilot study to conclude that alcohol quality has an influence on health as reflected in alcohol-attributable mortality rates. Given the extent of alcohol-attributable disease burden in central and eastern European countries, future research should focus on collection of large, representative samples, particularly of unrecorded sources, which was the most problematic product group in our study.

Aims: Some European countries with high levels of unrecorded alcohol consumption have anomalously high rates of death attributable to liver cirrhosis. Hepatotoxic compounds in illegally produced spirits may be partly responsible. Based on a review of the evidence on the chemical composition and potential harm from unrecorded alcohol, the Alcohol Measures for Public Health Research Alliance (AMPHORA) project's methodology for identifying, analysing and toxicologically evaluating such alcohols is provided. Methods: A computer-assisted literature review concentrated on unrecorded alcohol. Additionally, we refer to our work in the capacity of governmental alcohol control authority and a number of pilot studies. Results: The risk-oriented identification of substances resulted in the following compounds probably posing a public health risk in unrecorded alcohol: ethanol, methanol, acetaldehyde, higher alcohols, heavy metals, ethyl carbamate, biologically active flavourings (e.g. coumarin) and diethyl phthalate. Suggestions on a sampling strategy for identifying unrecorded alcohol that may be most prone to contamination include using probable distribution points such as local farmers and flea markets for selling surrogate alcohol (including denatured alcohol) to focusing on lower socio-economic status or alcohol-dependent individuals, and selecting home-produced fruit spirits prone to ethyl carbamate contamination. Conclusions: Standardized guidelines for the chemical and toxicological evaluation of unrecorded alcohol that will be used in a European-wide sampling and are applicable globally are provided. These toxicological guidelines may also be used by alcohol control laboratories for recorded alcohol products, and form a scientific foundation for establishing legislative limits.

Laugesen M; Epton M; Frampton CMA; Glover M; Lea RA. Hand-rolled cigarette smoking patterns compared with factory-made cigarette smoking in New Zealand men. BMC Public Health 9: article 194, 2009. (18 refs.)

Background: Roll-your-own (RYO) cigarettes have increased in popularity, yet their comparative potential toxicity is uncertain. This study compares smoking of RYO and factory-made (FM) cigarettes on smoking pattern and immediate potential toxicity. Methods: At a research clinic, 26 RYO and 22 FM volunteer male cigarette smokers, (addicted and overnight-tobacco-abstinent) each smoked 4 filter cigarettes, one half-hourly over 2 hours, either RYO or FM according to usual habit, using the CReSSMicro flowmeter. First cigarette smoked was their own brand. Subsequent cigarettes, all Holiday regular brand, were RYOs (0.5 g tobacco with filter), or FM with filter. Cravings on 100 mm visual analogue scale, and exhaled carbon monoxide (CO) were measured before and after each cigarette smoked. Results: Smokers reported similar daily cigarette consumption (RYO 19.0, FM 17.4, p = 0.45), and similar time after waking to first cigarette. (RYO 6.1 minutes, FM 8.6 minutes, p = 0.113). First cigarette's RYO tobacco (0.45 g) weighed less than for FM (0.7 g, p < 0.001); less tobacco was burnt (0.36 g, FM 0.55 g, p < 0.001) but smoking patterns were no different. RYO smokers smoked subsequent cigarettes more intensively; inhaled 28% more smoke per cigarette (RYO 952 mL, FM 743 mL, p = 0.025); took 25% more puffs (RYO 16.9, FM 13.6, p = 0.035); puffed longer (RYO 28 seconds, FM 22 seconds, p = 0.012), taking similar puffs (RYO 57 mL, FM 59 mL). Over four cigarettes, RYOs boosted alveolar CO (RYO 13.8 ppm, FM 13.8 ppm), and reduced cravings (RYO 53%, FM 52%) no differently from FM cigarettes. Conclusion: In these smokers, RYO smoking was associated with increased smoke exposure per cigarette, and similar CO breath levels, and even with filters is apparently no less and possibly more dangerous than FM smoking. Specific package warnings should warn of RYO smoking's true risk. RYOs are currently taxed much less than FM cigarettes in most countries; similar harm merits similar excise per cigarette.

Leitz J; Kuballa T; Rehm J; Lachenmeier DW. Chemical analysis and risk assessment of diethyl phthalate in alcoholic beverages with special regard to unrecorded alcohol. PLoS one 4(12): e-8127, 2009. (38 refs.)

Background: Phthalates are synthetic compounds with a widespread field of applications. For example, they are used as plasticizers in PVC plastics and food packaging, or are added to personal care products. Diethyl phthalate (DEP) may be used to denature alcohol, e.g., for cosmetic purposes. Public health concerns of phthalates include carcinogenic, teratogenic, hepatotoxic and endocrine effects. The aim of this study was to develop and validate a method for determining phthalates in alcohol samples and to provide a risk assessment for consumers of such products. Methodology/Principal Findings: A liquid-liquid extraction procedure was optimized by varying the following parameters: type of extraction solvent (cyclohexane, n-hexane, 1,1,2-trichlorotrifluoroethane), the ratio extraction solvent/sample volume (1:1 to 50:1) and the number of extraction repetitions (1-10). The best extraction yield (99.9%) was achieved with the solvent 1,1,2-trichlorotrifluoroethane, an extraction solvent volume/sample volume ratio of 10: 1 and a double extraction. For quantification, gas chromatography/mass spectrometry with deuterated internal standards was used. The investigated samples were alcoholic beverages and unrecorded alcohol products from different countries (n = 257). Two unrecorded alcohol samples from Lithuania contained diethyl phthalate in concentrations of 608 mg/L and 210 mg/L. Conclusions/Significance: The consumption of the phthalate-positive unrecorded alcohols would exceed tolerable daily intakes as derived from animal experiments. Both positive samples were labelled as cosmetic alcohol, but had clearly been offered for human consumption. DEP seems to be unsuitable as a denaturing agent as it has no effect on the organoleptic properties of ethanol. In light of our results that DEP might be consumed by humans in unrecorded alcohols, the prohibition of its use as a denaturing agent should be considered.

O'Connor RJ; Li QA; Stephens WE; Hammond D; Elton-Marshall T; Cummings KM et al. Cigarettes sold in China: Design, emissions and metals. Tobacco Control 19(Supplement 2): i47, 2010. (33 refs.)

Background: China is the home to the world's largest cigarette maker, China National Tobacco Company (CNTC), yet little is known publicly about the design and emissions of Chinese cigarettes. CNTC is currently in the process of consolidating its brands and has ambitions to export its cigarettes. Machine-measured tar yields of many of its cigarette brands have also been reduced, similar to what occurred in Western countries from the 1970s through the 1990s with so-called 'low-tar' cigarettes introduced to address consumer concerns about health risks from smoking. Method: The current study examines the design and physical characteristics, labelled smoke emissions and tobacco metals content of leading brands of Chinese cigarettes from seven cities purchased in 2005-6 and in 2007. Results: Findings suggest that similar to most countries, tar levels of Chinese cigarettes are predicted primarily by tobacco weight and filter ventilation. Ventilation explained approximately 50% of variation observed in tar and 60% variation in carbon monoxide yields. We found little significant change in key design features of cigarettes purchased in both rounds. We observed significant levels of various metals, averaging 0.82 mu g/g arsenic (range 0.3-3.3), 3.21 mu g/g cadmium (range 2.0-5.4) and 2.65 mu g/g lead (range 1.2-6.5) in a subsample of 13 brands in 2005-6, substantially higher than contemporary Canadian products. Conclusion: Results suggest that cigarettes in China increasingly resemble those sold in Western countries, but with tobacco containing higher levels of heavy metals. As CNTC looks to export its product around the world, independent surveillance of tobacco product characteristics, including tobacco blend characteristics, will become increasingly important.

Papastefanou C. Radioactivity of tobacco leaves and radiation dose induced from smoking. International Journal of Environmental Research and Public Health 6(2): 558-567, 2009. (30 refs.)

The radioactivity in tobacco leaves collected from 15 different regions of Greece and before cigarette production was studied in order to find out any association between the root uptake of radionuclides from soil ground by the tobacco plants and the effective dose induced to smokers from cigarette tobacco due to the naturally occurring primordial radionuclides, such as Ra-226 and Pb-210 of the uranium series and Ra-228 of the thorium series and/or man-made radionuclides, such as Cs-137 of Chernobyl origin. Gammaray spectrometry was applied using Ge planar and coaxial type detectors of high resolution and high efficiency. It was concluded that the activities of the radioisotopes of radium, Ra-226 and Ra-228 in the tobacco leaves reflected their origin from the soil by root uptake rather than fertilizers used in the cultivation of tobacco plants. Lead-210 originated from the air and was deposited onto the tobacco leaves and trapped by the trichomes. Potassium-40 in the tobacco leaves was due to root uptake either from soil or from fertilizer. The cesium radioisotopes Cs-137 and Cs-134 in tobacco leaves were due to root uptake and not due to deposition onto the leaf foliage as they still remained in soil four years after the Chernobyl reactor accident, but were absent from the atmosphere because of the rain washout (precipitation) and gravitational settling. The annual effective dose due to inhalation for adults (smokers) for Ra-226 varied from 42.5 to 178.6 mu Sv/y (average 79.7 mu Sv/y), while for Ra-228 from 19.3 to 116.0 mu Sv/y (average 67.1 mu Sv/y) and for Pb-210 from 47.0 to 134.9 mu Sv/y (average 104.7 mu Sv/y), that is the same order of magnitude for each radionuclide. The sum of the effective doses of the three radionuclides varied from 151.9 to 401.3 mu Sv/y (average 251.5 mu Sv/y). The annual effective dose from Cs-137 of Chernobyl origin was three orders of magnitude lower as it varied from 70.4 to 410.4 nSv/y (average 199.3 nSv/y).

The risk of exposure to ethyl carbamate from the consumption of kimchi, soy sauce, and alcoholic beverages was assessed in alcohol-drinking and nondrinking adults. An alcohol-drinking adult obtains 5.6-9.2 ng/kg bw/day of ethyl carbamate through the addition of kimchi and soy sauce, while a nondrinking adult receives 3.3-4.0 ng/kg bw/day via kimchi and soy sauce alone. The average excess cancer risk of an alcohol-drinking adult (3.9 x 10(-7)) was also twice higher than that of an adult who does not drink (1.9 X 10(-7)). We achieved a maximum of 47% and 45% removal of the ethyl carbamate present in diluted spirits and soy sauce, respectively, through a simple charcoal filtration process. This resulted in a reduction of the average daily intakes of ethyl carbamate through diluted spirits and soy sauce from 1.7 and 2.2 ng/kg bw/day to 0.9 and 1.2 ng/kg bw/day, respectively.

Issues. This contribution aims to examine systematically the evidence on the impact of the quality of unrecorded alcohol products on health consequences. Approach. Systematic computer assisted review of the literature. Key Findings. There are a number of pathways related to alcohol quality that may lead to acute or chronic health problems. The following constituents and contaminants of alcoholic beverages were identified as likely contributors to these problems: (i) toxic metals (e.g. lead) from contaminated water sources or unsuitable distillation equipment; (ii) volatile constituents, such as acetaldehyde or higher alcohols, which may be produced in significant amounts due to faults in production technology or microbiological spoilage; (iii) ethyl carbamate (urethane), a carcinogenic contaminant with major occurrence in certain fruit and sugarcane spirits; (iv) biologically active flavour compounds (e.g. coumarin in cosmetics used as non-beverage alcohol); (v) toxic compounds used to denature alcohol (e.g. methanol or diethyl phthalate). In addition, the often higher ethanol content may have detrimental health effects. These pathways should not be assumed as present for all subcategories of unrecorded alcohol, but are more relevant to certain types and geographic regions. Implications. A health impact of unrecorded alcohol over and above the effect of ethanol cannot be excluded. More research is urgently needed, especially with respect to liver disease and alcohol poisoning as endpoints. Conclusion. A feasible approach for new research on the effects of unrecorded alcohol could be based on a representative sample from low socioeconomic regions with high prevalence of unrecorded consumption.

Schayer S; Nowak B; Wang YL; Qu QS; Cohen B. Po-210 and Pb-210 activity in Chinese cigarettes. Health Physics 96(5): 543-549, 2009. (36 refs.)

The radon decay products lead-210 (Pb-210) and polonium-210 (Po-210) are known components of tobacco. China is the world's largest producer and consumer of cigarettes, yet no comprehensive published reports of the Pb-210 and Po-210 activity concentrations in Chinese cigarettes are available. Twelve brands of cigarettes that were commonly smoked within a group of 184 Chinese smokers were selected for Ph-210 and Po-210 activity analysis. For each brand, the tobacco from two cigarettes was isolated, dried, weighed, spiked with a (209)po tracer for yield, and digested with concentrated HNO3, followed by HCl. The polonium in each digested solution was spontaneously deposited onto a nickel disc. The polonium activity was then counted rising alpha spectroscopy. The mean (range) Po-210 activity for all brands was 23 (18-29) mBq cig(-1). The state of radioactive equilibrium between (210)To and Pb-210 in each cigarette was verified in three brands of cigarettes. Cigarettes from two brands were smoked on a machine in order to estimate the fraction of Pb-210 and Po-210 inhaled. An average of 8% of the Pb-210 and 13% of the Po-210 in the tobacco of the cigarettes was transferred to the mainstream smoke. It is thus estimated that a person smoking 20 of these cigarettes per day in China would inhale a mean (range) of 37 (29-46) mBq d(-1) of Pb-210 and 60 (47-75) mBq d(-1) of Po-210. Cigarette smoking in China may therefore be a large source of a person's daily intake of Pb-210 and Po-210.

Between October and December 2005, 16 cases of wound botulism were notified to the health authorities of North Rhine-Westphalia, Germany. All patients were injecting drug users (IDU) and the epidemiological investigations suggested contaminated injection drugs as the most probable source of infection. Clostridium botulinum was cultivated from clinical samples of six patients and molecular typing revealed that the different isolates were clonally identical. Two samples of heroin, one of them provided by a patient, were examined but C. botulinum could not be isolated. This outbreak demonstrates that IDU are at risk for acquiring wound botulism by injecting contaminated drugs. A greater awareness of this disease is needed by physicians and a close cooperation between public health authorities, street workers, operators of sheltered injecting facilities, and medical centres focusing on IDU is essential to prevent and manage outbreaks in IDU in a timely manner.

Sepetdjian E; Saliba N; Shihadeh A. Carcinogenic PAH in waterpipe charcoal products. Food and Chemical Toxicology 48(11): 3242-3245, 2010. (23 refs.)

Because narghile waterpipe (shisha, hooka) smoking normally involves the use of burning charcoal, smoke inhaled by the user contains constituents originating from the charcoal in addition to those from the tobacco. We have previously found that charcoal accounts for most of the polyaromatic hydrocarbons (PAH) and carbon monoxide in the smoke of the waterpipe, both of which are present in alarming quantities. Because charcoal manufacturing conditions favor formation of PAH, it is reasonable to assume that charcoal sold off the shelf may be contaminated by PAH residues. These residues may constitute a significant fraction of the PAH inhaled by the waterpipe user and those in her/his vicinity. We measured PAH residues on three kinds of raw waterpipe charcoal sampled from Beirut stores and cafes. We found that PAH residues in raw charcoal can account for more than half of the total PAH emitted in the mainstream and sidestream smoke, and about one sixth of the carcinogenic 5- and 6-ring PAH compounds. Total PAH content of the three charcoal types varied systematically by a factor of six from the charcoal with the least to the greatest PAH residue. These findings indicate the possibility of regulating charcoal carcinogen content.

Shahab L; West R; McNeill A. A comparison of exposure to carcinogens among roll-your-own and factory-made cigarette smokers. Addiction Biology 14(3): 315-320, 2009. (34 refs.)

Consumption of roll-your-own (RYO) tobacco is rising, but little is known about: its in vivo delivery of toxins relative to factory-made (FM) cigarettes. To start to address this issue, this study compared the concentrations of metabolites of recognized human carcinogens in smokers of RYO tobacco and FM cigarettes. We opportunistically recruited 1.27 FM and 28 RYO cigarette smokers in central London and collected saliva and Urine samples. Saliva samples were assayed for cotinine while urinary samples were assayed for I.-hydroxypyrene (1-HOP) and total 4-(methylnitrosamino)-1(3-pyridyl)-1-butanol (NNAL), metabolic markers of polycyclic aromatic hydrocarbons and tobacco-specific N-nitrosamines, respectively. Data on socio-demographic, anthropometric and puffing characteristics were also obtained. Both unadjusted and adjusted analyses (controlling for age, sex, body mass index, puff flow, puff duration and cotinine) showed no difference in metabolic markers between RYO and FM cigarette smokers. However, significant main effects for cotinine levels and sex were observed in adjusted analyses. Greater levels of cotinine were associated with a greater concentration of both I-HOP (B = 0.002, P = 0.037) and NNAL (B = 0.002, P < 0.001). In addition, women had significantly greater concentrations of urinary I.-HOP (B = 0.679, P = 0.004) and total NNAL metabolites (B = 0.117, P = 0.024) than men, irrespective of the type of cigarettes smoked. More research is now needed to confirm these findings and gender-specific effects in a larger representative sample. However, results do not support the common belief that RYO cigarettes are less harmful than manufactured cigarettes.

Twenty-four pharmaceuticals were measured in wastewater from 12 municipal wastewater treatment plants (M-WWTPs), four livestock WWTPs (L-WWTPs), four hospital WWTPs (H-WWTPs) and four pharmaceutical manufacture WWTPs (P-WWTPs). The total concentration of pharmaceuticals in the influent samples was highest in the L-WWTPs followed by the P-WWTPs, H-WWTPs and M-WWTPs. The effluents had different patterns of pharmaceuticals than their corresponding influents because of the different fate of each compound in the WWTPs. Non-steroidal anti-inflammatory drugs (NSAIDs) were the most dominant in the influents from the M-WWTPs and P-WWTPs, while antibiotics were dominantly detected in the L-WWTP. In the H-WWTP influents, NSAIDs, caffeine and carbamazepine were dominant. In the P-WWTPs, the distribution of pharmaceuticals in the effluents varied with sampling sites and periods. The M-WWTP influents had the highest daily loads, while the effluents showed somewhat similar levels in all source types.

Tahir SNA. Results of survey for assessing awareness level regarding radiological hazards of tobacco smoking. Radiation Protection Dosimetry 133(2): 111-114, 2009. (10 refs.)

Human consumption of tobacco is as old as human history. However, injurious health effects due to tobacco smoking may not be evident to the public at large. This article presents results of a questionnaire based on a survey carried out in the metropolitan city of Lahore of Pakistan with an aim to understand the awareness level of the general population about the radiological hazards associated with tobacco smoking. Some 3600 participants from different educational backgrounds from all segments of the society participated in this survey. Analysis of the data collected concluded that the awareness level of the representative participants regarding the radiological hazards associated with tobacco smoking was alarmingly poor. These results suggest that a nationwide mass media campaign may be launched by the government authorities in Health and Environment departments to enlighten the general public in this respect to avoid tobacco-smoking-associated health risks.

Talio MC; Luconi MO; Masi AN; Fernandez LP. Cadmium monitoring in saliva and urine as indicator of smoking addiction. Science of the Total Environment 408(16): 3125-3132, 2010. (24 refs.)

Cadmium is one of the many substances that may be acquired through active and passive smoking of tobacco. Saliva and urine are proposed for cadmium monitoring of non-smokers, second hand smokers, smokers and tobacco chewing appertaining to San Luis citizens without occupational exposition. Biological samples were collected by the same subjects, under strict proceeding instructions of sampling. Physical characteristics of samples were observed and checked with commercial test. Samples were analyzed using an adapted molecular fluorescence methodology with a previous extraction step. Stability of biological samples was daily studied for a period of one month. The method was successfully validated for accuracy, precision, linearity, specificity, and sensitivity. The simplicity and low coefficient of variance confirm the suitability of the method for urinary and salivary cadmium analyses. On the other side, the obtained results are in concordance with previous national epidemiological dates.

Objective. An epidemic of scopolamine poisonings occurred in Oslo in 2008 among users of illicit drugs, caused by fake Rohypnol (TM) pills. The clinical features, diagnostic process, and handling of the epidemic are presented. Methods. Suspected cases of scopolamine poisoning were extracted by reviewing registration forms from an ongoing prospective clinical study of acute poisonings in Oslo. Medical records of extracted contacts were examined and cases included according to specified clinical criteria. Results. Forty-four cases of probable scopolamine poisoning were registered. Main clinical features were mydriasis, visual hallucinations, plucking behavior, agitation, and coma. No clinical diagnosis of anticholinergic syndrome was made prior to forensic analysis of the tablets, the most frequent diagnosis up to this point being unspecified drug-induced psychosis. Later in the epidemic, scopolamine poisoning became the dominating diagnosis. Ten patients were admitted to psychiatric hospitals, the rest recovered in medical units, or left health care against medical advice. Discussion. Scopolamine poisonings are rare, but the resulting anticholinergic syndrome is well described. The syndrome was not recognized until the forensic analysis result strikingly changed how the patients were diagnosed and handled. A unique aspect of this epidemic was the intoxicating agent being scopolamine-containing tablets looking like Rohypnol (TM), sold and used under the impression of being the latter. Conclusion. Recognizing the anticholinergic syndrome is important to provide proper treatment. Forensic analysis was the key to correct diagnosis in this outbreak, demonstrating its importance in verifying an epidemic of poisoning by fake drugs.

We describe the case of a 40-year old Iranian man who was admitted to our hospital with severe abdominal pain, abnormal liver function tests and normocytic anemia. Suffering from multiple sclerosis, he was a regular user of opium for pain relief. Basophilic stippling of erythrocytes pointed towards the diagnosis of lead intoxication, the most likely source being contaminated Iranian opium. Serum lead and zinc protoporphyrin levels were strongly elevated. To assess the hepatotoxic effects of lead poisoning a liver biopsy was performed. Pathomorphologic findings of hepatotoxicity, rarely reported in humans, included active hepatitis together with extensive microvesicular and macrovesicular steatosis, hemosiderosis and cholestasis, and a lymphocytic cholangitis. Whilst treated with chelating therapy, liver enzymes returned to normal, suggesting reversibility of the histological findings.

Wilcox JA; Wilcox AH. Movement disorders and MDMA abuse. Journal of Psychoactive Drugs 41(2): 203-204, 2009. (12 refs.)

This article present the cases of two young men with chronic MDMA abuse who later developed movement disorders typical of the Parkinson's syndrome. It is worth noting that both men bought the presumed MDMA from the same illicit source. Potential risks of MDMA use and movement disorders are discussed. The risks inherent from contaminants and similar factors associated with illegal drug manufacture are discussed. The authors conclude that as long as nonpharmaceutical-grade MDMA is illicitly produced, health risks will be associated with its use.
