Though this study had a relatively small sample size (only 5 out of the 9 original participants finished the study), the patients that were involved showed promising results for the use of marijuana as a reliever of fibromyalgia pain. The patients were given orally administered tetrahydrocannabinol (THC) and ask to fill out various pain and sleep indexes and surveys. The researchers also induced pain via 1 Hz current pulses to the patient's forearms. It was found that THC was able to decrease patient's perception of both their fibromyalgia pain and of the electrically induced pain.
