The Greatest Story Never Told
Smoking Cannabis Does Not Cause Cancer Of Lung or Upper Airways, Tashkin Finds; Data Suggest Possible Protective Effect
The story summarized by that headline ran in O'Shaughnessy's (Autumn 2005), CounterPunch, and the Anderson Valley Advertiser. Did we win Pulitzers, dude? No, the story was ignored or buried by the corporate media. It didn't even make the "Project Censored" list of under-reported stories for 2005. "We were even censored by Project Censored," said Tod Mikuriya, who liked his shot of wry.
It's not that the subject is trivial. One in three Americans will be afflicted with cancer, we are told by the government (as if it's our immutable fate and somehow acceptable). Cancer is the second leading cause of death in the U.S. and lung cancer the leading killer among cancers. You'd think it would have been very big news when UCLA medical school professor Donald Tashkin revealed that components of marijuana smoke -although they damage cells in respiratory tissue- somehow prevent them from becoming malignant. In other words, something in marijuana exerts an anti-cancer effect.
Tashkin has special credibility. He was the lead investigator on studies dating back to the 1970s that identified the components in marijuana smoke that are toxic. It was Tashkin et al who published photomicrographs showing that marijuana smoke damages cells lining the upper airways. It was the Tashkin lab reporting that benzpyrene -a component of tobacco smoke that plays a role in most lung cancers- is especially prevalent in marijuana smoke. It was Tashkin's data documenting that marijuana smokers are more likely than non-smokers to cough, wheeze, and produce sputum.
Tashkin reviewed his findings April 4 at a conference organized by "Patients Out of Time," a reform group devoted to educating doctors and the public (as opposed to lobbying politicians). Some 30 MDs and nurses got continuing medical education credits for attending. The National Institute on Drug Abuse supported Tashkin's marijuana-related research over the decades and readily gave him a grant to conduct a large, population-based, case-controlled study that would prove definitively that heavy, long-term marijuana use increases the risk of lung and upper-airways cancers. What Tashkin and his colleagues found, however, disproved their hypothesis. (Tashkin is to marijuana as a cause of lung cancer what Hans Blick is to Iraq's weapons of mass destruction -an honest investigator who set out to find something, concluded that it wasn't there, and reported his results.)
