Marijuana and hallucinogen use in the past year reported by young adults 19 to 30 years old increased significantly in 2021 compared to five and 10 years ago, reaching historic highs in this age group since 1988, according to the study Monitoring the Future (MTF), an annual drug use survey of eighth, 10th and 12th grade students conducted by scientists at the University of Michigan’s Institute for Social Research, Ann Arbor.
Alcohol remains the most used substance among adults in the study, though past-year, past-month, and daily drinking have been decreasing over the past decade. Binge drinking (five or more drinks in a row in the past two weeks) rebounded in 2021 from a historic low in 2020, during the early stages of COVID-19 pandemic. On the other hand, high-intensity drinking (having 10 or more drinks in a row in the past two weeks) has been steadily increasing over the past decade and in 2021 reached its highest level ever recorded since first measured in 2005.
