This study examined the exchange of sexual services for compensation (e.g., money, drugs, alcohol) in high school students. The sale of sex in young people from nonclinical samples has been the subject of recent studies, but buying such services has received far less attention. This study described these two phenomena and associated factors within a nonclinical sample of 815 high school students (M = 15.86 years) from Québec. According to our results, 3% of these youth reported having bought and 4% reported having sold such services in their lifetime. More girls were involved in selling sexual services and more boys were involved in buying them. Young people generally disapproved of prostitution. Logistic regressions revealed that attitudes in support of prostitution, history of sexual abuse, casual sex, and the number of stressful life events were related to the sale of sex. Furthermore, observing sexualized social activities and exhibiting approving attitudes towards prostitution were associated with buying sexual services.
