Study reveals high oral cancer risk for cannabis and cigarette users

Recent research from UC San Diego reveals alarming statistics about oral cancer risk among users of both cannabis and cigarettes. The study shows that cigarette smokers are already five to ten times more likely to develop oral cancer compared to non-smokers. However, incorporating chronic marijuana use dramatically increases this risk. Users with cannabis use disorder were found to be 3.25 times more likely to develop the disease within five years, while those who smoked both cannabis and tobacco had a staggering 624% increased risk. The study analyzed data from over 45,000 patients, revealing cannabis smoke contains carcinogenic compounds similar to those in tobacco. This raises serious concerns about the long-term effects of cannabis and the need for heightened awareness of oral health issues among users.
