About The Study: In this nationally representative survey study of 19,000 youths, young adults, and adults, substance use decreased between 2019 and 2020 among those ages 13 to 20; consistent declines were not seen in older persons other than tobacco use reductions, and cannabis use increased among adults ages 25 and older. While social changes during the COVID-19 pandemic could have affected substance use, findings should be interpreted with caution due to differences in data collection methods in 2016 to 2019 and 2020.
