HealthDay News — Marijuana use by US college students in 2018 was the highest in 35 years, researchers report.

Their survey of about 1400 respondents, ages 19 to 22 years, revealed that about 43% of full-time college students said they used some form of marijuana at least once in the past year, up from 38% in 2017, and previous month use rose to 25% from 21%, the Associated Press reported Thursday.

The 2018 rates are the highest found in the annual University of Michigan survey since 1983. About 6% of college students said they used marijuana 20 or more times in the past month compared with 11% of respondents the same age who were not in college, the AP reported.
