In 2015, young adults in the United States (U.S.) reported co-use of tobacco and marijuana at a much higher rate than exclusive use of marijuana. While there is some qualitative research specific to using tobacco and marijuana separately, there is a lack of qualitative research studying poly/dual or co-use of these products and to understand the complex interactions between the varied modes of delivery for tobacco and marijuana. Qualitative research in this area is important especially due to the major developmental shifts that occur as youth transition into young adulthood. The proposed study is a descriptive analysis of qualitative data that will be drawn from 22 in-depth, semi-structured interviews that were conducted with a sub-sample of young adults (18-22 years of age) from the Texas Adolescent Tobacco and Marketing Surveillance System (TATAMS) from August through December of 2019.
