The Behavioral Risk Factor Surveillance System is an annual state-based telephone survey of adults throughout all 50 states, DC, and three territories. In 2022, the survey included an optional marijuana module that asked respondents who had reported past 30-day use to provide information on their routes of marijuana use.

Of the 138,625 adults that responded to the module, 15.3% of adults reported marijuana use in the past 30 days, with 7.9% reporting daily use. The most prominent users were young adults aged 18-24 years old, and smoking was ranked as the most prevalent route of use, at 79.4%. Following that, eating, vaping and dabbing were all popular at 41.6%, 30.3%, and 14.6% respectively.
