Addiction status is evaluated bythe CRAFFT-ADOSPA questionnaire and the academic achievements are recorded using the annual average (academic year: 2013-2014).

The results showed that the most commonly used drug is cannabis. Moreover, out of a total of 441 students, 29.5%are regular drug users, 10.8% of them are girls.
