Drug Watch International stated in its online position statement on medical marijuana, last updated on May 17, 2001:

“There is no scientific evidence that marijuana, which contains over 450 chemicals, many with harmful effects, is safe or effective for any medical condition. Synthetic THC, dronabinol, has been approved by the FDA for limited use as an anti-emetic agent for chemotherapy patients who fail to respond to other drugs, and as an appetite stimulant in low dosages for patients with AIDS wasting syndrome. This pharmaceutical is available by prescription (Marinol) and differs from crude marijuana in that it is a single, pure substance in stable, quantified dose.”
