Understanding use motives as predictive markers could fundamentally change how we approach early intervention and treatment planning. Clinical Summary This longitudinal study examined how different motivations for [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) predict clinical outcomes in adolescents with dual psychiatric and substance use disorders. The research tracked adolescents over time to determine which use motives — such as coping with negative emotions, social reasons, or enhancement-seeking — correlated with better or worse clinical trajectories. Adolescents using cannabis primarily for coping motives showed different longitudinal outcomes compared to those using for social or enhancement reasons, though specific mechanisms linking motives to clinical course remain unclear. Dr. Caplan’s Take “I’ve seen countless adolescents where we missed the window for effective intervention because we focused on quantity of use rather than motivation for use. The adolescent using cannabis to manage untreated anxiety follows a completely different clinical path than one using recreationally with peers.” Clinical Perspective 🧠 Clinicians should routinely assess not just frequency and quantity of cannabis use, but specifically why adolescents are using — particularly whether it’s primarily for [emotional regulation](https://cedclinic.com/cannabis-for-childrens-behavior/) versus social or recreational purposes. Coping-motivated use may signal underlying psychiatric conditions requiring more aggressive treatment, while also potentially indicating higher risk for problematic use patterns. This assessment should inform both psychiatric treatment intensity and substance use intervention strategies. 💬 Join the Conversation Have a question about how this applies to your situation?
