This study is one of the first to examine tobacco use among young adult sexual minorities using a nationally representative sample in the United States. Findings support previous research showing significantly higher tobacco use among sexual minorities compared with heterosexual adolescents and adults, with 33% of LGB young adults reporting any current tobacco use compared with 22% of heterosexuals. These findings are also consistent with the results of state-based studies showing smoking prevalence ranging from 25% to 37% among sexual minority adults
