New Studies Destroy the Last Objection to Medical Marijuana

Continued from previous page

A second study, by Dr. Mitch Earleywine at the University at Albany, State University of New York, involved an Internet survey of nearly 7,000 marijuana users. Participants were asked to identify their primary method of using marijuana (joints, pipe, vaporizer, edibles, etc.) and were asked six questions about respiratory symptoms. After adjusting for variables such as age and cigarette use, vaporizer users were 60 percent less likely than smokers to report respiratory symptoms such as cough, chest tightness or phlegm. The effect of vaporizer use was more pronounced the larger the amount of marijuana used.

"Our study clearly suggests that the respiratory effects of marijuana use can be decreased by use of a vaporizer," Earleywine commented. "In fact, because we only asked participants about their primary means of using marijuana, it's likely that people who exclusively use vaporizers will get even more benefit than our results indicate, because no doubt some in our study used vaporizers most of the time but not all of the time."

In a rational world, the government officials objecting to medical marijuana based on the health risks of smoking would greet this research with open arms. They would join with groups like the Marijuana Policy Project in spreading the word about this important, health-enhancing technology.

Don't hold your breath.
