Were included in this study, all the students of the two Junior Secondary Schools retained following the sampling; and having correctly completed the questionnaire and returned it. To carry out this work, we proceeded to a simple random sampling by drawing lots.

Results: The prevalence of SPA consumption was 35.5%, boys were read represented (64.8%), the age groups 12 – 16 years and 17 – 20 years were the most affected 41% each). In the majority of students (72%), parents were separated and 72% of them had repeated at least once. The most consumed substances were only cannabis (24%) and tobacco (8%), the combination tobacco + cannabis represented 44% and irregular consumption of these substances was the most frequent (66% for cannabis and 63% for the tobacco). The first experience of these substances was very early in 21% for cannabis and 49% for tobacco.

A study of all the schools in the capital city and at the national level seems essential to situate the extent of the phenomenon and analyze the various factors involved in order to provide appropriate solutions.
