Worth Repeating: 20 Years of Marijuana Smoking Reduces Risk of Head and Neck Cancer
A Population-Based Case-Control Study of Marijuana Use and Head and Neck Squamous Cell Carcinoma
Published in CANCER PREVENTION RESEARCH / JUNE 2009
Research preformed at Department of Pathology and Laboratory Medicine, Division of Biology and Medicine, Brown University, Providence, R.I.
Essentially what this very recent retrospective study found is that there is significantly reduced risk association between 10 to 20 years of marijuana use and a reduced risk of head and neck cancer.
Further, it also shows that there is reduced risk for head and neck cancer in people who make moderate use of marijuana each week and that the risk is reduced in people that start using marijuana at an older age.
