Associations Between Contact with the Criminal Legal System and Substance Use: The Trying to Understand Relationships, Networks and Neighborhoods Among Transgender Women of Color Study

PURPOSE: The objective of this study was to evaluate cross-sectional and longitudinal associations between contact with the criminal legal system (CCLS) and substance use among transgender women of color in New York City. METHODS: = 311). CCLS included arrest and incarceration and was measured at baseline, 6 months, and 12 months. Substance use included recreational substance use (any), alcohol use (any), and specific substance use (cannabis, cocaine, and methamphetamine). Generalized estimating equations were used to assess longitudinal associations between baseline CCLS and substance use over time. RESULTS: At baseline, 50.5% of participants reported having been arrested, and 28.0% reported experiencing incarceration. In multivariable analyses, CCLS was associated with substance use after controlling for confounders. In particular, at baseline, incarceration was associated with a 1.73 times (95% confidence interval: 1.06-2.81) likelihood of recreational substance use. We found no significant associations between CCLS and alcohol or specific substance use. CONCLUSION: The findings suggest that CCLS was associated with recreational substance use among transgender women of color at baseline. Substance use prevention and treatment programs should consider screening for substance use during reentry after incarceration and providing additional support for individuals with criminal legal system involvement.
