A new study reveals that daily marijuana smokers have a 3.25 times higher risk of developing oral cancer compared to non-users. Researchers at UC San Diego tracked 45,000 individuals for five years, finding that those with cannabis use disorder (CUD) had a significantly increased risk. The study highlights the presence of carcinogens in cannabis smoke similar to those in tobacco, impacting oral tissues and suppressing the immune system. The findings underscore the need for increased cancer screening in primary care and mental health settings, given the overlap of risk factors in CUD patients.
