The Institute for Social Research at the University of Michigan conducts an annual survey completed by students in grades 8, 10 and 12. A subset of that group is tracked through adulthood. Their headline finding of the Monitoring the Future survey this year was that marijuana and hallucinogen use among young adults 19 to 30 years old reached all-time high in 2021. Other key findings for young adults from the press release include:

• Nicotine vaping and alcohol use were up after a dip in 2020.
• Both cigarette smoking and non-medical use of opioid medications continue to decline over time.
