Study: History Of Cannabis Use Associated With Reduced Cancer Risk

Cannabis use is inversely associated with incidences of bladder cancer in males, according epidemiological findings published in the February issue of the journal Urology. “After adjusting for age, race or ethnicity, and body mass index, using tobacco only was associated with an increased risk of bladder cancer (hazard regression 1.52) whereas cannabis use was only associated with a 45 percent reduction in bladder cancer incidence (HR 0.55),” investigators reported.
