Variations in stigma by sexual orientation and substance use: An investigation of double stigma

Stigma can have a debilitating effect on mental health. Both LGBTQ+ individuals and substance users experience stigma, and concurrent membership of both groups can result in double stigma. This study aimed to investigate differences in stigmatized attitudes based on substance use behaviors and sexual identity using data from 102 participants (83% female). Findings suggest the presence of a hierarchy of stigma where heterosexual individuals were typically viewed more positively than LGBTQ+ individuals, regardless of the substance using status of the LGBTQ+ individual. However illicit drug use by heterosexual individuals resulted in the most negative attitudes. Implications are discussed.
