"According to CAN’s 2012 school population survey (Centralförbundet för alkohol- och narkotikaupplysning, 2013), very few students used drugs before the age of 14; 2% of the boys and 1% of the girls. The percentage of students who reported drug use before the age of 14 has been stable over the last 20 years.
"The percentage of students (15-16 years of age) who had had an opportunity to try drugs (for the first time) increased at the end of the 1990s and the increase continued until 2000 when 27% reported in the survey that they had had the opportunity to try drugs. From then on, the percentage decreased again and in 2012 it was 18%. The percentage of older students (17-18 years of age) who had had an opportunity to try drugs is somewhat larger, approximately 32 % (Centralförbundet för alkohol- och narkotikaupplysning, 2013."
