Differences in 30-Day Marijuana Use by Sexual Orientation Identity: Population-Based Evidence from Seven States

Purpose: The objective of this study was to compare 30-day marijuana use by sexual orientation identity. Methods: Data came from the 2016-2017 Behavioral Risk Factor Surveillance System. Prevalence estimates and logistic regression models compared 30-day marijuana use controlling for sociodemographic characteristics. Results: Lesbian women, gay men, and bisexual adults were more likely to use marijuana compared with heterosexual adults. Other characteristics predicting marijuana use included frequent mental distress, cigarette smoking, and binge drinking. Conclusion: Health professionals should identify the risk factors for elevated marijuana use, especially as more states legalize medical and recreational marijuana use despite uncertain health risks.
