arthritis is marked by painful inflammation of one or more joints. With known effects of cannabinoids in the reduction of pain and inflammation and in bone formation, cannabinoids offer great potential in the treatment of arthritis. However, to date, no large-scale, double-blind clinical trial has proven this potential.

Alternative Names

Prescription Advice

Clinical research suggests that (a mixture of) THC and CBD can be effective in the treatment of arthritis. Given the nature of the disease direct application to the skin/affected joint might be most efficient and avoids potential psychoactive effects of THC. Alternatively sublingual application could be effective.

Please follow generic prescription advice.

Literature Discussion

In mice genetically deficient for CB2, experimentally induced osteoarthritis was significantly worse than in control mice (Sophocleous et al., 2015). In addition, naturally occurring osteoarthritis was more severe in CB2 deficient mice than in controls.

This suggests that CB2 is involved in the development of (osteo-)arthritis and that CB2 activation may protect against osteoarthritis.

In mice with collagen-induced Arthritis a CBD dose of 5 mg/kg/day i.p. or 25 mg/kg/day oral effectively blocked disease progression and suppressed joint damage, lymphocyte proliferation and IFNγ and TNF expression (Malfait et al., 2000).

Clinical Trials

In one trial, a mixture of THC and CBD (Sativex) was found to be effective in reducing pain and stiffness and improving sleep (Blake et al., 2006)

In another study, inhibition of FAAH (which should increase endocannabinoid levels) failed to reduce pain in arthritis (Huggins et al., 2012). More and larger studies are required to assess the therapeutic potential of cannabinoids in arthritis.
