The document summarizes research on discrimination, substance abuse, and mental health issues within the homosexual community. Several studies found high rates of discrimination and victimization reported by LGBT individuals. Contributing factors to substance abuse and mental health problems among homosexuals include biological predispositions, social and family influences, stress from discrimination, and lack of support systems. However, factors may differ between individuals. Ongoing research is still needed to better understand these issues and find ways to reduce health risks in the gay community through social support programs and acceptance.
