What this research studies

You would be asked whether you currently use both cannabis and tobacco and complete surveys and short behavioral tasks that measure how much you want each product under different costs and situations. Researchers will follow participants over time to track changes in these measures and to see whether they predict dependence, quit attempts, or switching between products. They will also collect information on beliefs, perceived risk, social acceptability, and identity to see how these factors tie into wanting and using each substance. The team plans to combine these results into a theory-based model to guide future prevention and treatment efforts for dual users.

Who could benefit from this research

Good fit: Ideal participants are young adults who currently use both cannabis and tobacco.

Not a fit: People who do not use both substances, older adults outside the study's age range, or those seeking immediate clinical treatment may not directly benefit from participation.

Why it matters

Potential benefit: If successful, this work could help tailor prevention and quitting strategies for people who use both cannabis and tobacco.

How similar studies have performed: Prior behavioral economic studies have linked demand to dependence for single substances, but applying these methods specifically to cannabis–tobacco dual use is relatively new.
