To map the recent prevalence of alcohol and other psychoactive substances in deceased victims of traffic accidents in the Czech Republic.The studied sample consisted of individuals autopsied in the departments of forensic medicine who died during traffic accidents in 2008 and were toxicologically tested for one or more of the following substances: ethanol, volatile substances, cannabis, opiates, stimulants, cocaine, benzodiazepines, and barbiturates. Case definition involved alcohol cases with blood alcohol concentration (BAC) 0.2 g/kg and higher; with cannabis, detections of active THC metabolites only were taken into account; from cases where volatile substances (solvents) were detected we included into the positive cases only those where substances were not produced post mortem or in some physiological or pathological statuses.The sample consisted of 1,040 persons deceased in traffic accidents, of whom 582 (56.0%) were toxicologically tested for one or more of the substances listed above. The sample has been divided into two subsamples--one of 778 (74.8%) active participants of road traffic accidents (pedestrians, bicyclists, and drivers) and other subsample consisting of 262 (25.4%) non-active participants. Ethanol was found in 38.3% of 381 tested and at least one of other psychoactive substances was found in 11.7% of 384 tested active participants--of those, stimulants (mostly methamphetamine) were found most frequently (6.5% of 337 tested), cannabis (5.9% of 203 tested) and benzodiazepines (3.9% of 363 tested active participants). Drivers were positive for ethanol in 29.2% cases, for one or more of other psychoactive substances except ethanol in 12.7% cases, most frequently for stimulants (9.2%) and cannabis (6.2%). Professional drivers were found negative for ethanol and other psychoactive substance except of one case of methamphetamine (6.7%).The study confirms high prevalence of alcohol and other psychoactive substances, especially stimulants (methamphetamine), cannabis and benzodiazepines, among deceased participants of road traffic accidents including drivers in the Czech Republic. |
