Alcohol and Illicit Drugs among Subjects Involved in Road Crashes in Florence, Italy
Subscribe/Renew Journal
A collaborative study was performed in a period of time of 18 months in order to determine the prevalence of alcohol and other drugs (cannabinoids, opiates, cocaine, methadone and amphetamine) in 554 samples both urine and blood from people involved in vehicle crashes and admitted to an Emergency Department.
Thirty-five (6.3%) cases were positive only for alcohol, 6.1% (34 cases) of these blood alcohol concentration (BAC) was matched or exceeded the legal limit established in Italian highway code (0.5g/l). Nineteen blood samples (3.4%) result positive only for illicit drugs (cocaine, methadone, heroin and THC), while thirteen cases (2.3%) were positive both for alcohol and drugs.
These results highlight the increase of the risk of being involved in road traffic crashes using alcohol and other drugs most of all if we consider that the sample was taken no later than three hours after the accident.
