Researchers in Brazil have found that cannabis oil can be an effective treatment for patients with fibromyalgia, according to the results of a clinical trial completed recently. An abstract of the study, “Ingestion of THC-rich cannabis oil in people with fibromyalgia: A randomized, double-blind, placebo-controlled clinical trial,” was published last week in the journal Pain Medicine.
To conduct the study, researchers tested the effectiveness of a plant-derived cannabis oil on 17 women with fibromyalgia (FM), a chronic pain syndrome characterized by widespread musculoskeletal pain and fatigue. The patients were treated over a period of eight weeks with a cannabis oil rich in THC. The initial dose was one drop per day, with subsequent dosage increases according to symptoms. The mean dose for those in the cannabis group was 3.6 drops per day, equating to a total of 4.4 milligrams of THC and 0.08 milligrams of CBD per dose.
Patients were separated into two groups, one of which received the cannabis oil, while the members of the control group received a placebo. The Fibromyalgia Impact Questionnaire (FIQ) was administered at pre- and post intervention moments and in five visits over eight weeks. The researchers reported that “the impact of the intervention
