Cannabis use linked to increased risk of head and neck cancers
Study finds regular heavy use of marijuana may increase overall risk of developing certain cancers
Excessive use of cannabis was associated with a higher risk of head and neck cancers, according to a study published Thursday in JAMA. The study found that people who used marijuana daily for years had a significantly higher risk of developing head and neck cancers, including tumors of the mouth, throat, windpipe, and salivary glands.
The study was conducted by researchers at the University of California, San Francisco, and included data from over 100,000 adults. The researchers followed the participants for an average of 10 years and found that those who used marijuana daily were 2.3 times more likely to develop head and neck cancers than those who did not use marijuana.
The study's findings are consistent with previous research that has linked marijuana use to an increased risk of cancer. However, this is the first study to specifically examine the relationship between marijuana use and head and neck cancers.
The researchers believe that the increased risk of head and neck cancers among marijuana users may be due to the fact that marijuana smoke contains many of the same carcinogens as cigarette smoke. In addition, marijuana smoke can damage the cells in the mouth and throat, making them more susceptible to cancer.
The study's findings are concerning, as head and neck cancers are relatively common and can be difficult to treat. The researchers hope that their findings will help to raise awareness of the potential risks of marijuana use and encourage people to make informed decisions about their health.
