Background:
Adolescent risky behaviours are influenced by a wide range of factors such as gender, culture, family, personal perceptions or society.

Purpose of the study:
Evaluation of tobacco use among adolescents aged 13–16 years in Vlora in order to identify the factors that influence its use.

Methodology of the study:
This is an analytical study conducted during the period March – May 2019. This study included 360 adolescents in Vlora. Two questionnaires were used: the Youth Risk Behaviors Questionnaire and the Youth Tobacco Questionnaire.

Results:
The average age of adolescents was 14.52 years, 59.7% were male, 64.4% reported having used tobacco at least once, 21.7% have tried it for the first time at age 9–10 years. Females were those who had previously experienced tobacco. Curiosity, society, adolescents’ perception that smoking relieves stress, or smoking helps reduce appetite are the factors that influence smoking (p≤0.009). Adolescents whose parents smoke were more likely to smoke (p=0.015). In all, 89.11% of adolescents had tried alcoholic beverages with a higher tendency among males. Only 0.6% of adolescents had tried marijuana.

Conclusion:
Tobacco consumption significantly affects the consumption of alcoholic beverages and vice versa (p=0.0003). The consumption of cigarettes in the last 30 days also influenced the amount of marijuana used, but not necessarily regularly (p=0.0001). Adolescents who are non-casual users of tobacco and alcohol are likely to become casual users of marijuana.
