Marijuana use tied to poorer school performance

Thursday, May 11, 2017

When high school students started smoking marijuana regularly they were less likely to get good grades and want to pursue university, according to a new study from the University of Waterloo. 

The study, published in the Journal of School Health, found that when students started using marijuana at least once a month they were about four times more likely to skip class, two-to-four times less likely to complete their homework and value getting good grades, and about half as likely to achieve high grades, than when they had never used the drug.
