Outrageous Anti-Pot Lies: Media Uses Disgraceful Cancer Scare Tactics | DrugReporter | AlterNet
On Tuesday, January 29 — three days prior to the publication of a forthcoming study assessing marijuana use and cancer — Reuters News Wire published a story under the headline: “Cannabis Bigger Cancer Risk Than Tobacco.” Mainstream media outlets across the globe immediately followed suit. “Smoking One Joint is Equivalent to 20 Cigarettes, Study Says,” Fox News declared, while Australia’s ABC broadcast network pronounced, “Experts Warn of Cannabis Cancer ‘Epidemic.’”

If those headlines weren’t attention-grabbing enough, one only had to scan the stories’ inflammatory copy — much of which was lifted directly from press statements provided by the study’s lead author in advance of its publication.

“While our study covers a relatively small group, it shows clearly that long-term cannabis smoking increases lung-cancer risk,” chief investigator Richard Beasley declared. Beasley went on to speculate that pot “could already be responsible for one in 20 lung cancers diagnosed in New Zealand” before warning: “In the near future we may see an ‘epidemic’ of lung cancers connected with this new carcinogen.”

The mainstream press, always on the look out for a good pot scare story, ran blindly with Beasley’s remarks. Apparently not a scribe among them felt any need to confirm whether Beasley’s study — which remained embargoed at the same time it was making worldwide headlines — actually said what was claimed.

It didn’t.

For those who actually bothered to read the study’s full text, which appeared in the European Respiratory Journal days after the global feeding frenzy had ended, they would have learned the following. Among the 79 lung cancer subjects who participated in the trial, 70 of them smoked tobacco. These individuals, not surprisingly, experienced a seven-times greater risk of being diagnosed with lung cancer compared to tobacco-free controls. As for the subjects in the study who reported having used cannabis, they — on average — experienced no statistically significant increased cancer risk compared to non-using controls.
