In 2020 cannabis use among college students reached its highest level during the 21st Century. The National Institute on Drug Abuse’s 2020, Monitoring the Future study, tracking substance use in adults between the ages of 19 and 22, revealed that in 2020 44% of college students used cannabis in the last year, compared with 38% in 2015. Of that number 8% admitted to “heavy” usage. Cannabis use is likely to increase among this and younger age groups, as it has become legal in many states. Nearly half of people 12 years old or older in the United States have used cannabis at least once in their lives, according to NIDA statistics, and almost 17% of all adults are current users.
