The report by Marie Choquet (Epidemiologist, Director of Research at INSERM) and Professor Jacques Weill concludes that the average number of drinks consumed by 13-18 year olds has remained unchanged at 20 glasses a month (1985-1996). Looking at age groups within the sample however, 13/14 year olds are drinking considerably less than in 1985 ( 3.5 glasses against 5.5) but 15/16 year olds have increased their consumption to 23 glasses a month from 13. Drinking tends to take place at weekends, in bars and night clubs. On average boys are drunk 13 times in their lives and girls 5 times.
