The Medical Minute: Is Cannabis Helping you Prevent Bladder Cancer?

According to the 2015 report of the California Men’s Health Study, cannabis use was associated with a 45% decreased risk of bladder cancer. Researchers analyzed results from an 84,170-person survey that identified the rates of cannabis and tobacco use in 2002-2003:

  • 47,092 (57%) reported tobacco use
  • 22,500 (27%) reported using both
  • 23,467 (29%) reported using neither
