A University of Michigan study of 8,722 Americans aged 12–34 who had used a tobacco, nicotine, and/or cannabis product within the last month found that traditional smoking remains prevalent even as vaping and edibles grow in popularity. Researchers identified six main usage patterns: combustible tobacco (31%), multiple forms of cannabis (27%), nicotine vaping (18%), combined use of nicotine, tobacco, and cannabis (14%), cannabis edibles only (5%), and multiple forms of nicotine and tobacco (5%).
The study also highlighted narrowing gender differences and higher usage rates among Black and African American youth and young men, suggesting targeted prevention and cessation programs are needed. The study appears in the American Journal of Preventive Medicine and was funded by the National Cancer Institute and NIH.
