The variables were tobacco dependence (Fagerstrom-FC) and frequency use of this substance. Statistics analysis: descriptive measures, 95%CI (precision of estimates).

RESULTS: The prevalence of smoking experimentation was 16.1% (95%CI:15.1-17.2), 30.9% (95%CI:27.6-34.4) of these, consumed it in the last month. The adolescents consumed it 1 to 9 days (66.1%; 95%CI=58.5-72.8), however 16.4% consumed it for more than 20 days in the last month, and 9.2% use 20 cigarettes or more in the same period. The estimation of tobacco dependence by FC, 24 adolescents fulfilled the six FC. Most of them presented lightweight dependency, however, 25% (IC95%=12-44.9) presented high scores, greater than five (moderate to severe). Whereas FC, the number of cigarettes consumed per day (27.9 % use 10 cigarettes or more) and the difficulty of not smoking in “no smoking” places (19,5%;95%CI=14.7-25.5) were the most frequent.
