Introduction: Adolescence is a period not only of physical and psychological transformation but also of curiosity, experimentation and acquisition. The aim of the present study is to determine the prevalence of smoking, alcohol and other drug use among children in middle and high school.

Methods: This was a cross-sectional observational study including 507 students whose age is between 15 and 19 years old. Data collection was based on a self-administered questionnaire consisting of questions relating to: socio-demographic data; smoking status; tobacco, alcohol and drug use.

Results: The prevalence of smoking was 22.1%. Tobacco consumption was higher among students over the age of 18 years old (36.6%). A significant male predominance was noted (17.5% vs 4.9%). The age of the first cigarette was less than 10 years in 31.2% of cases. Most student smokers bought their own cigarettes from a tobacco seller. The prevalence of e-cigarette use was 12%. The prevalence of snuff tobacco use was 9.1% at least once in a lifetime and 3.9% for current users. The prevalence of hookah smoking was 4.5%. The prevalence of alcohol use was 5.9% with a male predominance (4.7% vs 1.2%). The prevalence of drug use was 4.7% : cannabis in 3.5% of cases  and psychotropic drugs without medical prescription in 0.4% of cases.

Conclusion: There is a need to collect nationwide data on the use of different forms of tobacco, alcohol and drug  by adolescents, and the factors leading to initiation of such harmful habits. There is an urgent need to take effective steps, especially on launching community awareness programs for the school children and public to educate them about the consequences of tobacco use.
