US CO: Column: Does Smoking Pot Cause Strokes?

Westword, 07 Mar 2013 – Dear Stoner: My wife was telling me that she heard on TV that smoking pot can cause strokes in older folks. I’m 63 and just a little concerned. Any truth to this rumor? Roberto Reefer Roller Dear RRR: Back in February, a New Zealand scientist said he had found a link between cannabis use and certain types of strokes in people under the age of 55. Out of 160 stroke patients, 16 percent tested positive for marijuana. That was twice as high as the number of cannabis users in a control group with similar conditions and signs, but who had not progressed to a stroke. While the scientists and news media made a big deal out of those findings, they downplayed the more important part of the study: All but one of the 16 percent smoked cigarettes, which can more than double the risk of having an ischemic stroke.
