Cannabis therapy mitigates symptoms of the chronic pain condition fibromyalgia and is associated with a reduction in the use of other prescription drugs, according to clinical data published online ahead of print in the Journal of Clinical Rheumatology. An estimated 3 to 6 million Americans are afflicted by fibromyalgia, which is often poorly controlled by standard pain medications.
Israeli investigators assessed the safety and efficacy of inhaled cannabis in a cohort of 26 patients with fibromyalgia. They reported that medical cannabis treatment “was associated with significant favorable outcomes in every item evaluated,” such as reductions in pain and increases in energy.
Most patients also reduced their use of conventional prescription drugs, such as opiates and benzodiazepines, during the trial period. Nearly half of the participants (46 percent) reduced their prescription drug intake by more than 50 percent during the study. Several patients were also able to return to work following the initiation of cannabis therapy.
Researchers concluded, “Medical cannabis treatment had a significant favorable effect on patients with fibromyalgia, with few adverse effects.”
Prior trials evaluating the use of either whole-plant cannabis or synthetic cannabinoids have similarly shown efficacy in patients with the disease. A summary of these prior studies is available here.
