According to a new study, first published on June 27th in the peer-reviewed journal BMJ Open Respiratory Research, marijuana users are 22% more likely to visit the emergency room or be hospitalized compared to those who do not.
The study was conducted in Ontario, Canada, surveying 30,000 residents between the ages of 12 to 65 over a 6-year period. The findings remained consistent even when adjusting the analysis for over 30 other confounding factors, including other illicit drug use, alcohol use and tobacco smoking.
These findings are just the newest scientific studies that are raising concerns about the effects of marijuana use on both physical and mental health, including another large study released in January 2022 that found a negative impact of tetrahydrocannabinol (THC), the main psychoactive compound in cannabis, on the brain's higher levels of thinking.
