Drugs and alcohol consumption amongst Spanish drivers

We have analysed patterns of alcohol and regular drug consumption by Spanish drivers. Six hundred and seventy five properly completed questionnaires were received from drivers attending three medical traffic centres in Valladolid (Spain) for medical examination prior to obtaining or renewing their driving licence in 1990. Among those surveyed, 24% were 'daily' drinkers and 56.7% were 'weekly' drinkers, the majority (55.5%) being 'light' drinkers (1-39 g/day of pure alcohol). Of those surveyed 28.9% took drugs. The most commonly consumed drugs were analgesics (6.5%), anti-allergic drugs (5.2%) and oral contraceptives (4.6%). Of those drivers taking drugs 28.2% were 'daily' drinkers and 53.8% were 'weekly' drinkers. The study indicates widespread consumption of alcohol and drugs by Spanish drivers.
