Research study targets marijuana and tobacco users who want to quit

The Innovative Programs Research Group, an organization in the UW School of Social Work, is recruiting people 18 and older for a free marijuana and tobacco treatment trial. The study is aimed at adults who are regularly using both substances, want to quit marijuana and are willing to consider kicking the tobacco habit as well.

This group tends to struggle when it comes to quitting marijuana. Rates of tobacco use are high among regular cannabis users — between 40 and 90 percent, depending on the study and the population — and people who seek treatment for marijuana use who are also smokers tend to have poorer outcomes and higher relapse rates, principal investigator Denise Walker said.
