Daily marijuana use among US college students reaches 40-yr high


Washington, Sep 10 : Daily marijuana use increased in 2020 to an all-time high among US college students over the past four decades, according to the University of Michigan's (UM) annual national Monitoring the Future (MTF) panel study. Daily marijuana use, defined as using on 20 or more occasions in the past 30 days, increased to 7.9 per cent in 2020 among 19 to 22-year-old full-time college students, showing a significant increase of 3.3 percentage points over the past five years, Xinhua news agency quoted the study as saying. Among same-aged young adults not in college, daily use was 13 per cent in 2020, below the all-time high of 15 per cent in 2019, representing a non-statistically significant decline in 2020. Meanwhile, the annual use of marijuana last year was at historic high levels of 44 per cent since the early 1980s among college students and of 43 per cent among same-aged youth not in college. Another main finding is that the use of hallucinogens, including LSD, psilocybin mushrooms and other psychedelic substances, continued to increase, especially among college students. Annual use of any hallucinogen increased 8.6 per cent for college students from 2019 to 2020, the highest since 1982. Among same-aged young adults not in college, annual use was 9.8 per cent in 2020, the highest in two decades. A third main finding is that college drinking declined in 2020, perhaps due to the Covid-19 pandemic. Among college students, both 30-day use and 30-day drunkenness decreased significantly between 2019 and 2020 to 56 per cent and 28 per cent, respectively. Cigarette use among young adults continues its long-term decline, with past 30-day use at a new all-time low of 4.1 per cent in 2020 for college students, showing a significant 3.8 percentage point decline from 2019; it also reached a new all-time low of 13 per cent in 2020 for non-college respondents in 2020, the study found. The ongoing MTF study has been tracking college students and same-aged youth not in college every year since 1980. The new findings are from surveys conducted between March 30, 2020, just after the national shutdown due to the Covid-19 pandemic, through November 30, 2020. /IANS
