Still limitations in both studies suggest that we still don’t have a clear picture of smoked cannabis’ effect on our lungs.
This new study, from researchers at University of Queensland in Australia, examined whether chronic cannabis smoking was associated with damaging effects on the lungs of young adults, specifically. “Cannabis use is increasingly legalized and use is becoming normalized.” Lead author Professor Jake Najman explains. “In this context, understanding more about the harms associated with long-term cannabis use is important.”
