Age Differences in Daily and Non-daily Cannabis Use in the United States, 2002-2014

Course overview

This course examines age difference in cannabis use in the US between 2002-2014. Previous research indicate a change in use in 2007, thus the data is separated before and after that year. The measure daily vs non-daily use. Daily use was defined as use 300 days of the year or more. The authors found an overall increase in use, as well as an increase in frequency of use. The reasons cited for this increase were: increasingly permissive cannabis legislation, attitudes, and lower risk perception.
