What this research studies

You would be asked about the messages you hear about cannabis and how those messages affect your reasons for using it and your use patterns. The research team will conduct interviews with cannabis users, dispensary staff (budtenders), growers, and health care providers who talk with patients about cannabis. They will also collect and code cannabis-related messages from websites, social media, and retail settings to characterize sources, content, and any risk warnings. Finally, the team will link the types of messages people receive to their reported motives for use and subsequent cannabis consumption.

Who could benefit from this research

Good fit: Adults who currently use cannabis (for medical or recreational reasons), especially those who buy from dispensaries or discuss cannabis with health providers, are ideal candidates.

Not a fit: People who do not use cannabis, are under 18, or who do not interact with cannabis information sources may not receive direct benefit from this work.

Why it matters

Potential benefit: Could help people make safer, more informed choices about cannabis by clarifying which messages encourage use or downplay risks.

How similar studies have performed: Other health communication research shows that message source and content influence behavior, but applying mixed methods specifically to cannabis messaging is relatively new.
