[Drunkenness in traffic in Geneva: occasional abuse or alcoholism?]

The main aim of the study is to measure the importance of alcoholism amongst alcohol intoxication (up to the Swiss legal BAC: 0.8 gr/kg) in traffic. The method used describes the characteristics of all cases of inebriety (amongst pedestrians and drivers) recorded by the police during one year and relates this with complementary data such as the determination of a biological marker of alcohol consumption (Gamma Glutamyl Transferase), or DWI recidivism. Results of general interest are: 22% of recorded cases of alcohol intoxication are recidivists; about one third of the cases of alcohol intoxication registered are due to alcoholism rather than to social drinking. A preventive policy in road traffic safety must integrate the problems, caused by alcoholism, on Public Health.
