Abstract: Stigma and discrimination faced by gay and bisexual men (GBMSM) can lead to minority stress, which often results in coping behaviors such as substance use, including crystal methamphetamine or party drugs, and sex with multiple partners. This study examines the relationship between internalized homonegativity and external sexual minority stigma with substance use and sexual behavior among GBMSM in Los Angeles. Analysis of data from 54 participants recruited through the Gay Social Networking Analysis Program in 2018 revealed that homonegativity correlated with increased crystal methamphetamine and party drug use. White and Hispanic/Latino GBMSM showed lower rates of crystal methamphetamine use compared to Black/African American GBMSM. External stigma was linked to higher likelihood of group sex participation. The findings indicate that GBMSM experiencing greater stigma may adopt behaviors affecting their health as coping mechanisms to reduce minority stress and seek connection. The study suggests psychological interventions and peer support as potential solutions.
