Marijuana Use Linked to Increased Risk of Head and Neck Cancers

Study Finds Regular Heavy Use May Raise Risk by 35%

People Who Use Marijuana at High Levels May Be at Greater Risk

A new study published in the journal Head and Neck Oncology has found that people who use marijuana at high levels are putting themselves at more than three times the risk of developing head and neck cancers.

The study, which was conducted by researchers at the University of California, San Francisco, looked at data from over 500,000 people. The researchers found that people who smoked marijuana daily for five or more years were 3.5 times more likely to develop head and neck cancers than those who did not use marijuana.

The risk of developing head and neck cancers was even higher for people who used marijuana in combination with tobacco. People who smoked both marijuana and cigarettes were 5.6 times more likely to develop head and neck cancers than those who did not use either substance.

The study's findings are concerning, as they suggest that marijuana use may be a risk factor for a serious type of cancer. More research is needed to confirm the findings of this study and to determine the mechanisms by which marijuana may increase the risk of cancer.

In the meantime, people who are considering using marijuana should be aware of the potential risks associated with this drug.
