"Among students aged 15-16, approximately 40% of those who had used drugs also reported a large consumption of alcohol and this was a much higher proportion than among students with no reported drug use (8%). Further, among students aged 17-18, there was a large difference between students with and without experience of drug use with regard to extensive alcohol consumption, although the difference was not as large as for students aged 15-16 (Centralförbundet för alkohol och narkotikaupplysning, 2014c). There was also an association between reported drug use and binge drinking. Among students who reported drug use, almost 57% of 15- and 16-year-olds and 74% of 17- and 18-year-olds reported monthly binge drinking. This is a considerably higher percentage than could be found among students with no drug experience. Use of tobacco was also more common among students with experience of drug use, compared with students with no drug experience (Centralförbundet för alkohol och narkotikaupplysning, 2014c)."
