Over the last several years, laws about marijuana use have been changing across the United States. Methodology Center researchers Jessica Braymiller, Ashley Linden-Carmichael, and Stephanie Lanza wanted to know how marijuana use and attitudes about marijuana use might be changing in the face of those legal changes. In a recent article in Journal of Adolescent Health, the authors examined these questions using data from the 2010-2016 waves of the Monitoring the Future study.
The authors applied latent class analysis (LCA) to reveal patterns in marijuana use and attitudes among high school seniors in the United States. The analysis revealed that beginning in 2014, increases were observed in two subgroups: nonusers who are tolerant of marijuana use and marijuana users who generally approve of marijuana use at any level (i.e., experimentation, occasional use, and regular use).
