The pain-relieving effects of marijuana depend on the dose10/25/2007 Smoking marijuana in "moderate" doses can relieve pain, but increasing the dosage, on the contrary, increases the pain. Such conclusions were reached by American scientists based on the results of a study on volunteers, the journal Anesthesiology reports.Specialists from the University of California studied the pain-relieving effect of marijuana on 15 healthy volunteers. All participants were given subcutaneous injections of capsaicin, a substance found in chili peppers, which caused pain. After that, all participants smoked cigarettes with a certain concentration of the main psychoactive component, 9-delta-tetrahydrocannabinol (THC): 2%, 4%, 8%, or placebo. The pain-relieving effect of marijuana was assessed at certain intervals using a special questionnaire. It turned out that during the first 5 minutes, none of the doses of marijuana had any effect on pain. After 45 minutes of using marijuana, the participants who smoked cigarettes with 4% THC noted a decrease in pain. In contrast, the use of 8% THC led to an increase in pain. Cigarettes with 2% THC had no effect on pain levels, the scientists noted. "Our study showed that there is a therapeutic window for pain relief: low doses are ineffective, medium doses relieve pain, and high doses increase pain," said study leader Mark S. Wallace. The reason why marijuana caused increased pain is not yet clear, but scientists have suggested that this effect is not related to the effects of THC, but due to one of the 400 other components contained in marijuana leaves. Wallace and his colleagues said further research is needed into the pain-relieving effects of marijuana. At the same time, experts note that the results of experiments on healthy volunteers cannot be automatically transferred to patients with cancer or multiple sclerosis. MedPortal
