Study: History Of Marijuana Use Associated With Reduced Cancer Risk
(via healthtap.com)
Paul Armentano, NORML Deputy Director
Cannabis use is inversely associated with incidences of bladder cancer in males, according epidemiological findings published in the February issue of the journalUrology.
Investigators at the Kaiser Permanente Los Angeles Medical Center, Department of Neurology assessed the association of cannabis use and tobacco smoking on the risk of bladder cancer in a multiethnic cohort of more than 80,000 men aged 45 to 69 years old over an 11-year period.
Researchers determined that a history of cannabis use was associated with a decreased risk of bladder cancer. By contrast, tobacco use was associated with an increased risk of cancer.
“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.
Subjects who reported using both tobacco and cannabis possessed a decreased risk of cancer (HR 1.28) compared to those subjects who used tobacco only (HR 1.52).
The study is the first to indicate that cannabis use may be inversely associated with bladder cancer risk.
