Could smoking marijuana really prevent cancer? A recent study suggests that moderate marijuana use is associated with reduced risk of head and neck squamous cell carcinoma (HNSCC), better known as head and neck cancers. Numerous recent studies have shown that cannabinoids have anti tumor effects which most likely explains why marijuana smokers are less likely to get head and neck cancers.
Our study suggests that moderate marijuana use is associated with reduced risk of HNSCC.
We found that moderate marijuana use was significantly associated with reduced risk of HNSCC. This association was consistent across different measures of marijuana use (marijuana use status, duration, and frequency of use). Further, we observed that marijuana use modified the interaction between alcohol and cigarette smoking, resulting in a decreased HNSCC risk among moderate smokers and light drinkers, and attenuated risk among the heaviest smokers and drinkers.
