The University of Maryland’s Center on Young Adult Health and Development released a paper from their ongoing College Life Study. This study followed 1,253 students for 10 years, beginning in their first year of college. Students were assessed annually on their marijuana use and 9 health outcomes including functional impairment due to injury and psychological distress, and physical health service utilization. The study found that students who did not use marijuana had better outcomes than students who did. Students that used marijuana for a limited time fared worse than students who did not use at all, but better than students who maintained or increased their use through time.
