Introduction: Alcohol and cannabis are commonly used among young adults, with simultaneous use linked to greater negative consequences. Two-year college students are understudied and may differ from 4-year students in demographics, life circumstances, and risk factors. Methods: Participants were 234 young adults (18-29 years) enrolled in 2-year colleges reporting recent, elevated alcohol and/or cannabis use. Latent class analysis (LCA) identified patterns of use and related consequences. Demographics and perceived peer and parental norms were examined in relation to class membership using multinomial logistic regression. Results: Four classes emerged: alcohol-only (27%), cannabis-only (13%), alcohol, cannabis, and simultaneous use (28%), and alcohol, cannabis, and simultaneous use with high consequences (33%). Male gender, higher parental approval of cannabis, younger age, and not living with parents were associated with membership in the two higher-risk classes. Discussion: Results highlight heterogeneous substance use among 2-year students and the importance of parental norms, informing targeted prevention strategies.
