According to the annual U.S. national surveillance for the future (MTF) team at the University of Michigan, the number of people aged 19 to 22 who smoke marijuana and nicotine more than doubled between 2017 and 2019.
In addition, in 2019, the number of young people aged 19 to 22 using marijuana in any form reached or approached the highest level in the past 40 years.
Between 2017 and 2019, the proportion of adults aged 19 to 22 who smoked marijuana at least once in the past 30 days rose from 5% to 14% among full-time college students and from 8% to 17% among non university students.
Similarly, between 2017 and 2019, the prevalence of 30 day smoking among college students increased from 6% to 22%, and from 8% to 18% among adults aged 19 to 22 who did not go to college.
“In just two years, the prevalence of cannabis and nicotine use has doubled to tripled, one of the biggest increases in history since the study began more than 40 years ago,” said lead researcher John Schulenberg of the MTF study. Considering the health risks associated with smoking, including the increased risk of covid-19 and nicotine addiction, this is a worrying trend. “
