How Will Mainstream Media Spin This Government Study?

The Rorschach Inkblot test asks people to make up stories about ambiguous pictures. Rorschach’s hope was that the tales people told about each blot would reveal something about personal predilections and an approach to the world. Well, our friends at the National Institute on Drug Abuse have just published a nice inkblot test for the media. The experiment, “Tolerance to Effects of High-Dose Oral D9-Tetrahydrocannabinol and Plasma Cannabinoid Concentrations in Male Daily Cannabis Smokers,” is about (you guessed it!) developing tolerance to THC. We’ll see how media handle the implications of the results. It’s either a reassuring result for those concerned about safety on the roads or a chance for misguided alarms about purported dependence.

The experimenters drafted 13 guys who were experienced cannabis smokers to stay in the lab for several days. Each day, they had to swallow more and more Marinol. Marinol is pure THC in a pill, but without the cannabinoids and various compounds found in whole plant cannabis that mitigate the psychotropic effects of THC and perform other beneficial health functions. Many people have reportedthat Marinol left them far more impaired than plant cannabis, undoubtedly for this very reason. In fact, one guy dropped out “for personal reasons” and another “due to psychological reactions to THC.” These guys had smoked marijuana at least 1,000 times, so I’m guessing that they would have had a handle on “psychological reactions to THC” if they’d been allowed to (heaven forbid!) use their own stash. But the dosage was nothing to sneeze at — 120 mg of THC per day — or the equivalent amount of THC as three joints of decent medical cannabis in the U.S.
