Young people's participation in sexual risk behaviours is commonly linked with participation in a range of other risky behaviours, and in particular with substance use behaviours. This cross-sectional analysis of the sixth sweep of the Belfast Youth Development Study aimed to examine associations between substance use and sexual activity and related risks among 17–19-year olds in Northern Ireland. Being sexual activity and participating in sexual risk behaviours was associated with the use of a range of licit and illicit substances particularly alcohol and ecstasy.
