A recently published study examined substance use disparities among sexual minority youth. The current subsample of 348,175 students participated in the Youth Risk Behavior Surveillance System (YRBSS) study from years 2005 to 2015.
· Female lesbian and bisexual youth were at risk of initiating substance use at younger ages and, among lifetime users, were more likely to persist in their tobacco and marijuana use over time, relative to sexually active female heterosexual youth.
· Among lifetime users, male youth with partners of both sexes were at greater risk of persistent use of alcohol, tobacco, and marijuana over time and earlier ages of first use.
