There is mounting anecdotal and clinical evidence in support of the use of cannabis for treating cancer, and bladder cancer in men is no exception. A recent study led by Dr. Anil A. Thomas and published in the Journal of Urology examined data collected from 84,170 participants aged 45-69 in the California Men's Health Study cohort. The results suggest marijuana may decrease the risk for bladder cancer in men.
In the study, researchers looked at demographic lifestyle factors, like the use of tobacco or marijuana, and then linked the information with electronic clinical records. Out of all of the participants, 279 eventually developed bladder cancer, of which 89 participants reported using marijuana in comparison with 190 participants who did not. Researchers adjusted various confounding factors and found that marijuana coincided with a 45% decreased risk of bladder cancer. Tobacco use, both with or without marijuana use, increased the risk for developing bladder cancer.
This study offers support for the use of cannabis for decreasing the risk of developing bladder cancer, but Marijuana Investor News reminds us, "Although these findings will be exciting to some, many scientists will be quick to point out that this is just one study and that more research will need to be conducted." It would be interesting to look at the ways in which marijuana is able to prevent bladder cancer in men, but until the plant is removed from the list of schedule I substances, researching and gathering this information will continue to be difficult.
