Sexual risk taking among young adult dual alcohol and marijuana users.

Use of alcohol and marijuana among college students is common and use of these substances may increase the likelihood of risky sexual behavior. The present study found significant associations between risky sexual behavior and both mean BAC per drinking day and marijuana use intensity. However, hypothesized interactions between marijuana use and BAC were not supported. In addition, positive and negative urgency and premeditation were each significantly associated with the likelihood of risky sex. Substance use and facets of impulsivity and self-control exhibited direct associations with risky sexual behavior but hypothesized moderation effects were not supported. Associations between urgency and risky sexual behavior varied as a function of gender and trait positive affect.
