The average number of alcoholic beverages consumed on a typical day was 3.3, the average number of cigarettes consumed on a typical day was 2.2, the average use of marijuana was 1.2, and that of cocaine was 2.5. 66.8% of the participants have consumed alcohol at some time in their life, 49.9% have consumed alcohol in the last year. 18.5% have consumed cigarettes at least once in their life and only 13.6% consumed it in the last year. 7.2% of adolescents have used marijuana at some time in their life and only 3.8% used it in the last year. 3.4% have used cocaine at some time in their life and 1.9% in the last year.
