According to a new study published in the journal Pain Medicine and epublished by the National Institute of Health, the daily use of marijuana oil is effective and well-tolerated among patients with fibromyalgia.

For the study researchers examined the efficacy of high-THC marijuana oil versus a placebo in patients with fibromyalgia over an eight-week period. On average patients received 3.6 drops per day of marijuana oil that had 4.4 mg of THC and 0.08 mg of CBD (both very low numbers).

Researchers found that the marijuana oil was associated with “extended significant reduction” in subjects’ symptoms, as assessed by the Fibromyalgia Impact Questionnaire (FIQ). Placebo controlled patients received no such benefit.

The study states: “[T]he impact of the intervention on quality of life in the cannabis group participants was evident, resulting in reports of well-being and more energy for activities of daily living. Pain attacks were also reduced.”

The study concludes by stating that “To our knowledge, this is the first randomized controlled trial to demonstrate the benefit of cannabis oil – a THC-rich whole plant extract – on symptoms and on [the] quality of life of people with fibromyalgia. We conclude that phytocannabinoids can be a low-cost and well-tolerated therapy for symptom relief and quality of life improvement in these patients, and we suggest that this therapy could be included as an herbal medicine option for the treatment of this condition in the Brazilian public health system.”

Objective: To determine the benefit of a tetrahydrocannabinol (THC)-rich cannabis oil on symptoms and quality of life of fibromyalgia patients.

Methods: A double-blind, randomized, placebo-controlled clinical trial was conducted for eight weeks to determine the benefit of a THC-rich cannabis oil (24.44 mg/mL of THC and 0.51 mg/mL of cannabidiol [CBD]) on symptoms and quality of life of 17 women with fibromyalgia, residents of a neighborhood with a low socioeconomic profile and a high incidence of violence in the city of Florianopolis, Brazil. The initial dose was one drop (∼1.22 mg of THC and 0.02 mg of CBD) a day with subsequent increases according to symptoms. The Fibromyalgia Impact Questionnaire (FIQ) was applied at pre- and postintervention moments and in five visits over eight weeks.

Results: There were no significant differences on baseline FIQ score between groups. However, after the intervention, the cannabis group presented a significant decrease in FIQ score in comparison with the placebo group (P = 0.005) and in comparison with cannabis group baseline score. (P < 0.001). Analyzing isolated items on the FIQ, the cannabis group presented significant improvement on the “feel good,” “pain,” “do work,” and “fatigue” scores. The placebo group presented significant improvement on the “depression” score after intervention. There were no intolerable adverse effects.

Conclusions: Phytocannabinoids can be a low-cost and well-tolerated therapy to reduce symptoms and increase the quality of life of patients with fibromyalgia. Future studies are still needed to assess long-term benefits, and studies with different varieties of cannabinoids associated with a washout period must be done to enhance our knowledge of cannabis action in this health condition.
