Boys in the age of 17 to 21 from rural districts smoked cigarettes in 23%, girls in the equal age from rural regions in 14%. 17% of the non-smokers and only 2% of the smokers did not drink any alcohol. In Berne, 23% of the cigarette smokers and only 3% of non-smokers had ever taken drugs (marihuana, LSD) in their life.
