Summary

The purpose of this study is to determine whether or not inhaled marijuana displays any pain-relieving properties on experimentally-induced pain.

Detailed description

It is important to evaluate the effects of the cannabinoids on facilitated pain as conditions of hyperalgesia more closely approximates the clinical situation. There are limited clinical studies on the effect of the cannabinoids on facilitated pain states. Noyes et al evaluated the analgesic effects of Delta-9-THC in 34 cancer patients with pain. They concluded that 20mg of oral Delta-9-THC was similar to 120mg of codeine (Noyes et al, 1975). Jain et al concluded that 1.5-3mg of intramuscular Levonantradol resulted in significant pain relief as compared to placebo in 56 patients with acute postoperative pain (Jain et al, 1981). Comparison(s): Three different doses of smoked cannabis will be compared to placebo for the reduction of experimentally induced pain.
