Purpose The non-medical use of prescription medications among adolescents has become a concerning public health issue. This study assessed the prevalence of the non-medical use of prescription medications in Ontario high school students, and explored the moderating effect of this use on the relationship between psychological distress and unmet mental health needs. Methods Cross-sectional data for 4896 students, age 14–18, were drawn from the 2019 Ontario Student Drug Use and Health Survey. Psychological distress was measured using the Kessler-6 Distress Scale, unmet mental health needs were defined by self-report (yes/no), and non-prescription medication use was defined by self-reported frequency of use. Using logistic regression, we explored the effect of the non-medical use of prescription medications on the relationship between psychological distress and unmet mental health needs. Results High proportions of Ontario students reported serious psychological distress (22%), some degree of unmet mental health need (38%), and/or non-medical use of prescription medications (13%). While there were strong associations between psychological distress and unmet mental health need, this association was weaker among those reporting non-medical use of prescription medications (OR = 3.3, 95% CI 1.9–5.7) compared to non-users (OR = 5.6, 95% CI 4.5–7.1). Conclusion Our findings suggest that Ontario students experiencing distress and using non-prescribed medications are less likely to identify a need for mental health support, highlighting the consequences of apparent self-medication through misuse of prescription medications. To assist in the redirection of adolescent perceptions of healthy coping strategies, population-based educational programming, with targeted promotion of both formal and informal mental health care resources, should be considered.
