[Trends in Abuse of Biogenic Drugs in Parts of Germany 2007-2013]. / Entwicklung des Missbrauchs psychotroper Pflanzen und Pilze in Deutschland ­ Interpretation der Zahlen aus 3 Giftinformationszentren für die Jahre 2007­2013.

AIM OF THE STUDY: Based on an abundance of information on the internet, psychotropic plants and mushrooms are of increasing relevance as legal and cheap alternatives to other illicit drugs. Due to the lack of a German database, the abuse of selected biogenic drugs using reported exposures to 3 German Poison Information Centres (PICs) was examined. METHODS: Information on abuse of biogenic drugs was collected from the German PICs in Berlin, Erfurt and Fribourg (2007-2013). RESULTS: 602 drug abuses were reported to the selected PICs. 52% reported consumption of tropane alkaloid-containing plants (Angel's trumpet, Thorn apple, Belladonna), 25% of psilocybin-containing mushrooms and 10% of nutmeg. Angel's trumpet was identified as the most abused plant. Consumers of tropane alkaloid-containing plants were mainly adolescents, whereas the majority of the abusers of psilocybin-containing mushrooms and nutmeg were rather young grown-ups and school children, respectively. A preponderance of moderate and severe effects (55%) could be noticed for exposures to tropane alkaloid-containing plants. More than 90% of suspected cases of tropane alkaloid-containing as well as psilocybin-containing plants abuse resulted in the treatment recommendation 'surveillance in hospital'. Mydriasis, hallucinations, tachycardia and agitation were the main symptoms after the abuse of biogenic drugs. CONCLUSIONS: The data from the PICs suggest abuse of biogenic drugs in parts of Germany. A decreasing trend is observed, probably caused by the competition with new synthetic designer drugs. The results underline the dominance of Angel's trumpet in the abuse of biogenic drugs and emphasize the importance of easy accessibility for the abuse of biogenic drugs. Unexpectedly, the number of nutmeg abuse cases increased during the investigated period.

Workplace bullying and psychotropic drug use: the mediating role of physical and mental health status.

OBJECTIVES: The association between workplace bullying and psychotropic drug use is not well established. This study was aimed at exploring the association between workplace bullying, and its characteristics, and psychotropic drug use and studying the mediating role of physical and mental health. METHODS: The study population consisted of a random sample of 3132 men and 4562 women of the working population in the south-east of France. Workplace bullying, evaluated using the validated instrument elaborated by Leymann, and psychotropic drug use, as well as covariates, were measured using a self-administered questionnaire. Covariates included age, marital status, presence of children, education, occupation, working hours, night work, physico-chemical exposures at work, self-reported health, and depressive symptoms. Statistical analysis was performed using logistic regression analysis and was carried out separately for men and women. RESULTS: Workplace bullying was strongly associated with psychotropic drug use. Past exposure to bullying increased the risk for this use. The more frequent and the longer the exposure to bullying, the stronger the association with psychotropic drug use. Observing bullying on someone else at the workplace was associated with psychotropic drug use. Adjustment for covariates did not modify the results. Additional adjustment for self-reported health and depressive symptoms reduced the magnitude of the associations, especially for men. CONCLUSIONS: The association between bullying and psychotropic drug use was found to be significant and strong and was partially mediated by physical and mental health.

Workplace bullying and sleep disturbances: findings from a large scale cross-sectional survey in the French working population.

STUDY OBJECTIVES: The purpose of this study was to explore the associations between workplace bullying, the characteristics of workplace bullying, and sleep disturbances in a large sample of employees of the French working population. DESIGN: Workplace bullying, evaluated using the validated instrument developed by Leymann, and sleep disturbances, as well as covariates, were measured using a self-administered questionnaire. Covariates included age, marital status, presence of children, education, occupation, working hours, night work, physical and chemical exposures at work, self-reported health, and depressive symptoms. Statistical analysis was performed using logistic regression analysis and was carried out separately for men and women. SETTING: General working population. PARTICIPANTS: The study population consisted of a random sample of 3132 men and 4562 women of the working population in the southeast of France. RESULTS: Workplace bullying was strongly associated with sleep disturbances. Past exposure to bullying also increased the risk for this outcome. The more frequent the exposure to bullying, the higher the risk of experiencing sleep disturbances. Observing someone else being bullied in the workplace was also associated with the outcome. Adjustment for covariates did not modify the results. Additional adjustment for self-reported health and depressive symptoms diminished the magnitude of the associations that remained significant. CONCLUSIONS: The prevalence of workplace bullying (around 10%) was found to be high in this study as well was the impact of this major job-related stressor on sleep disturbances. Although no conclusion about causality could be drawn from this cross-sectional study, the findings suggest that the contribution of workplace bullying to the burden of sleep disturbances may be substantial.
