Bottom Line: The association between marijuana use and the risk of developing different kinds of cancer remained largely unclear in this analysis of 25 studies. The available studies were limited by small numbers of participants with high levels of marijuana use, poor quantification of marijuana use, and the presence of other factors such as cigarette smoking, which could influence results. Long-term studies are needed to improve understanding of marijuana’s association with the risk of developing cancer.
