The daily administration of plant-derived, THC-rich cannabis oil is effective and well-tolerated among patients with fibromyalgia, according to clinical trial data published in the journal Pain Medicine. Fibromyalgia (FM) is a chronic pain syndrome characterized by widespread musculoskeletal pain and fatigue.
A team of Brazilian researchers assessed the efficacy of THC-rich cannabis oil versus placebo in patients with FM over an eight-week period. The mean dose used in the cannabis group was 3.6 drops a day (4.4 mg of THC and 0.08 mg of CBD).
Cannabis dosing was associated with an “extended significant reduction” in subjects’ symptoms, as assessed by the Fibromyalgia Impact Questionnaire (FIQ). Patients receiving placebo did not experience similar reductions.
