Smoking cigarettes puts the user at a higher risk for bladder cancer, an effect that has been well noticed within the realm of medical professionals. Californian doctors have been on a study for eleven years to track marijuana and cigarette users to compare the effects of both products on bladder health. Tobacco users were evidently more unhealthy in all sectors, but marijuana users were actually 45% less likely to develop bladder cancer.
Medical professionals from the Kaiser Permanente Los Angeles Medical Center have used over 84,000 medical records and questionnaire surveys in the California Men’s Health Study. Their results showed that “cannabis use only was associated with a 45 percent reduction in bladder cancer incidence.” Over 41% of the group reported that they used marijuana, while 57 said that they smoked cigarettes. 27% used both, and 29% used none of the substances. Other factors were taken into consideration, such as age, race, BMI, but despite that, only tobacco use increased the possibility of developing bladder cancer. Cannabis users, on the other hand,
After adjusting for confounding factors like age, race, ethnicity and body mass index, doctors only found that tobacco use increased the likelihood of developing bladder cancer, while cannabis users were 45 percent less likely to develop that type of cancer.
These findings are the only association, and not entirely proving of anything; however, they call for more research, which will produce more interesting findings. Marijuana may itself have some positive effect on the bladder, or perhaps pot users have more beneficial bladders because they drink more water from their mouths drying up. Either way you slice it, marijuana users have the advantage.
