Medical marijuana as the new herbalism, part 1: Science versus the politics of weed in New York and beyond

A while 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 of the SBM blog might expect, I was not particularly impressed or approving of this particular bit of infiltration of quackademic medicine into a major 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 least implausible) of modalities commonly associated with “complementary and alternative medicine” (CAM) or “integrative medicine”, it still exhibits a number of problems, the biggest of which is what I like to call either the delivery problem or the bioavailability problem. In brief, herbs, when they work, are adulterated drugs. The active ingredient is usually a minor constituent, embedded in thousands of other constituents that make up herbs, and it’s almost impossible to control lot-to-lot consistency with respect to content or active ingredients given how location, weather, soil conditions, rainfall, and many other factors can affect how the plants from which the medicines are extracted grow and therefore their chemical composition. To demonstrate the concept, I pointed out that it’s much safer and more predictable to administer digoxin to a patient who needs its activity on the heart than it would be for the patient to chew on some foxglove leaves, given that the therapeutic window (the difference between the doses needed to produce therapeutic effects and the lowest dose that will cause significant toxicity) is narrow.

Which brings me to medical marijuana, a.k.a. medical cannabis.

Food Allergies and Food Addiction

Last week I wrote about the CME presentations at an obesity course put on by the American Society of Bariatric Physicians. I saved the most controversial one for last. Dr. Kendall Gerdes is a former president of the American Academy of Environmental Medicine, which I have previously written about. The AAEM is not recognized by the American Board of Medical Specialties and is categorized by Quackwatch as a questionable organization. Dr. Gerdes spoke on food allergies and food addiction.

I wasn’t convinced: I thought much of what he said was questionable. I thought, as a challenge for our readers, it might be an interesting exercise to present his information without comment and let readers look for flaws and form their own opinions. At the end, I’ll offer some suggestions of things to think about.

He described the concept of food addiction as a powerful tool to free patients from compulsive eating. Patients may “have the experience of” being addicted to foods or have symptoms of hunger and of just not feeling well. Specific symptoms of food addiction include fatigue, fibromyalgia, GI symptoms, cardiac arrhythmias, asthma, rhinitis, arthritis and seizures. There is no “gold standard” way to diagnose food allergies. He relies mainly on avoidance and challenge. (more…)
