Cannabis Use Among Court-Involved Minority Sexual Orientation and Gender Identity Adolescents

We examined the effects of family functioning and beliefs regarding peers' cannabis use among minority (n = 112) and non-minority (n = 275) sexual orientation and gender identity (SOGI), firsttime court-involved adolescents. We examined longitudinally the effects of baseline general family functioning and peer cannabis use beliefs on self-reported cannabis use and cannabis-related consequences after 12 months. At baseline, 39.2 percent of adolescents reported using cannabis. Minority SOGI adolescents reported worse family functioning (p = .017) and higher peer cannabis use beliefs (p = .047). Higher peer cannabis use beliefs at baseline predicted recent cannabis use at the 12 month assessment for both minority and non-minority SOGI adolescents. Better family functioning predicted a lower likelihood of recent cannabis use at 12 months for non-minority SOGI adolescents, but not for minority SOGI adolescents. Baseline peer cannabis use beliefs and family functioning predicted cannabis-related consequences for both cohorts at 12 months when accounting for intermediate (i.e., four-month and eight-month) data. Among all first-time court-involved adolescents, those who believed greater cannabis use among their peers reported more subsequent cannabis use themselves. Conversely, higher general family functioning may be less of a protective factor for minority SOGI adolescents. These results suggest the utility of feedback interventions to modify peer norm beliefs among first-time court-involved adolescents.
