Medical Marijuana

I must admit that I'm surprised. Pleasantly surprised, but quite surprised. The reason is that yesterday the Department of Licensing and Regulatory Affairs Director Mike Zimmer rejected the recommendation of the Michigan Medical Marijuana Review Panel to add autism to the list of qualifying conditions for which cannabis can be prescribed in the state of Michigan. I didn't expect this outcome, but I am pleased. Although I've changed my mind over past stands and am now in favor of legalizing marijuana for recreational use, I have been harshly critical of the "medical marijuana" movement. Indeed…

When I first started writing about the claims made for medical marijuana and the cannabis oil derived from it, it didn't take long for me to characterize medical claims for cannabis as the "new herbalism," as opposed to pharmacognosy, the branch of pharmacology devoted to the study of natural products. The reason is simple. Although I support legalization of marijuana for recreational use, when I look at how medical marijuana has been promoted as a "foot-in-the-door" prelude to legalization, I see testimonials and flimsy evidence ruling over all. I see all the hallmarks of alternative…

My opinion about medical marijuana has been fairly consistent. First, the claims made by its advocates for it far exceed the evidence for its benefit, which is why I've referred to it as the "new herbalism." Of course, it's not really very new, but it is herbalism in that medical marijuana advocates make grandiose claims for using their favorite "drug" in its plant form rather than doing the standard thing that modern medicine does with natural products and try to isolate the active compounds, in this case a class of molecules known as cannabinoids. Second, although medical marijuana might…

About five weeks ago a month ago, I finally wrote the post I had been promising to write for months before about medical marijuana. At the time, I also promised that there would be follow-up posts. Like Dug the Dog seeing a squirrel, I kept running into other topics that kept me from revisiting the topic. However, recently the New York Times gave me just the little nudge I needed to come back and revisit the topic, first by openly advocating the legalization of marijuana, then by vastly overstating the potential medical benefits of pot (compare the NYT coverage with my post from last month…

Three months ago, I wrote about how the Cleveland Clinic had recently opened a clinic that dispensed herbal medicine according to traditional Chinese medicine (TCM) practice. As regular readers might expect, I was not particularly impressed or approving of this particular bit of infiltration of quackademic medicine into a major, generally well-respected academic medical center, particularly given some of the amazingly pseudoscientific treatments espoused by the naturopath who was running the clinic. I also pointed out that, although herbalism is the most plausible (or perhaps I should say the…

by Kim Krisberg For years, Peter Rosenfeld was looking for an effective way to treat what doctors had diagnosed as severe and intractable migraines. He'd heard of medical marijuana, but thought it was a joke — that it was just a way for people to justify their marijuana use. Then in 2000, the New Jersey resident enrolled in a California program studying the effects of medical marijuana. It was a blind study, so Rosenfeld didn't know whether he was one of the participants being given marijuana or not. It turns out he was. And it worked. "Marijuana was the first effective treatment that I had…

Update: New ScienceBlogs colleague, Sharon Astyk at Casaubon's Book, brought my attention to the fact that this local southern Colorado story has been picked up by CNN. Although I originally wrote this post rather tongue-in-cheek, some scientific evidence has accumulated for the benefits of cannabis in neuropathic pain, cancer pain and nausea, as well as muscle spasticity in multiple sclerosis. For what appears to be a subset of individuals, marijuana is superior to prescription drugs in terms of efficacy and side effect profile. Equivocal results with a standardized cannabis extract…

In a collaboration with Reason magazine, Drew Carey has released a video defending the free availability of marijuana for medical purposes. Click here to see it. Money quote: "Smell that smell. That's the smell of freedom."
