Understanding how young adults use marijuana and tobacco together
Official title: Using novel behavioral economic measures to characterize dual marijuana and tobacco use in young adults
Funded at Brown University · NIH-11048597 · Data updated 2026-11-12
This study looks at how young adults use both marijuana and tobacco together, exploring what influences their choices and how changes in price or availability of one might affect their use of the other, all to find ways to help reduce health risks linked to using both substances.

Who could benefit from this research
✓Could help
Ideal candidates for this research are young adults who currently use both marijuana and tobacco.
✕Less likely to help
Patients who do not use either marijuana or tobacco may not benefit from this research.
What this research studies
This research investigates the patterns of marijuana and tobacco use among young adults, focusing on the behavioral mechanisms that drive dual use of these substances. By employing innovative behavioral economic measures, the study aims to understand how changes in the availability and pricing of one substance affect the demand for the other. The research will involve laboratory-based tasks to assess how young adults respond to cues related to both marijuana and tobacco, providing insights into their consumption behaviors. Ultimately, the goal is to identify strategies to reduce the health risks associated with dual substance use.
Why it matters
Potential benefit: If successful, this research could lead to better prevention strategies for substance use disorders and reduced cancer risk among young adults.
How similar studies have gone: Previous research has shown that understanding behavioral economics can effectively inform substance use interventions, suggesting potential for success in this novel approach.
