Help-seeking is uncommon among college students with substance use concerns. Perceived access to services is associated with greater help-seeking behavior. This study identifies substance use-related risk factors associated with awareness of campus counseling services. College students aged 18 to 25 (N = 995) self-administered a web-based survey, reporting their demographics, substance use history, well-being, and counseling services available at their institution. Multiple logistic regression was used to identify factors associated with awareness of services. Overall, 78% of students were aware of counseling services available at their institution. Full-time enrollment (p = 0.038) and better mental well-being (p = 0.025) were associated with greater odds of awareness of services. Early initiation of substance use (p = 0.003) and past month high-intensity drinking (p = 0.003) were associated with lower odds of awareness of services. Innovative strategies are needed to ensure campus counseling services reach students at risk for substance use-related problems.
