Background:

Marijuana consumption is a public health problem.

Aim:

To determine the life time prevalence of marijuana use among Colombian adolescents and the factors associated with its consumption.

Material and Methods:

Secondary analysis of data from a study aimed to determine the prevalence of smoking. A self-administered and anonymous questionnaire was answered by 814 adolescents aged 14 ± 2 years (439 women).

Results:

Ten percent of respondents consumed marijuana at least once in their life. A logistic regression analysis showed that professing a non-christian religion, being smoker and having an age over 12 years, was associated with marijuana consumption.

Conclusions:

There is a high frequency of marijuana use among these adolescents.
