SAN DIEGO, US: As cannabis use becomes more common, its health risks remain under investigation—particularly its impact on cancer. Some users develop cannabis use disorder (CUD), a medical diagnosis for problematic cannabis use that causes significant impairment in daily life. A recent study explored the link between CUD and oral cancer. It found that people with CUD are over three times more likely to develop oral cancer within five years than people who had never used cannabis and those who used it without developing a disorder. The findings underscore potential long-term oral health risks of cannabis use and highlight the need to update oral cancer screening practices.
