The study, which was published in The American Journal of Drug and Alcohol Abuse, collected data from the National Survey on Drug Use and Health between 2002 and 2013. According to a press release issued on Monday, responses were aggregated from 105,903 younger adolescents (ages 12 to 14), 110,949 older adolescents (ages 15-17), and 221,976 young adults (ages 18-25).
Marijuana Disapproval Rate Down Among Millennials.
Among adults aged 18 to 25, the study identified a downward disapproval rating — from 41% to 23% — with only a marginal 2% spike in cannabis usage.
With the recent trend of cannabis legalizations, researchers wanted to see if these policy changes had an impact on usage and beliefs surrounding the plant.
“Our results may suggest that recent changes in public policy, including the decriminalization, medicalization and legalization of marijuana in cities and states across the country, have not resulted in more use or greater approval of marijuana use among younger adolescents,” said Christopher Salas-Wright, an assistant professor at UT-Austin and lead author of the study.
