Adverse Health Impact of Marijuana
A January 2024 paper in the Annual Review of Medicine (published online August 2023) catalogues the adverse health effects of marijuana across multiple body systems: cardiovascular (heart attack, stroke), respiratory (chronic bronchitis, COPD-like symptoms in smokers), cognitive (memory, executive function), psychiatric (psychosis, anxiety, depression), and reproductive (fertility, pregnancy outcomes).
Annual Reviews are explicitly review papers — they summarize what the field's consensus is. This one's framing is unambiguous: marijuana use has documented adverse effects across organ systems, particularly in heavy and adolescent users.
