Phytocannabinoids, the active compounds found in cannabis plants (such as THC and CBD), have been investigated for their potential role in supporting or treating autoimmune conditions like lupus (systemic lupus erythematosus, SLE). Current use is driven primarily by scientific interest, though robust clinical evidence is limited. Preclinical studies and some small clinical reports suggest that cannabinoids possess anti-inflammatory, immunomodulatory, and analgesic properties. These effects are mediated through interactions with the body’s endocannabinoid system, particularly CB1 and CB2 receptors, which are involved in immune regulation and pain signaling.

A handful of studies have explored cannabinoids in the context of general autoimmune diseases, demonstrating potential reductions in pro-inflammatory cytokines and improvements in chronic pain and sleep disturbances, which are common in lupus. However, there are no large-scale, high-quality randomized controlled trials specifically evaluating phytocannabinoids for lupus. Most supporting evidence comes from animal models, laboratory research, or patient self-reports. Some patients with lupus report symptom relief (especially pain, insomnia, and mood) with medical cannabis or CBD products, but these outcomes are largely anecdotal.

Major medical organizations do not currently endorse phytocannabinoids as a standard treatment for lupus due to the lack of robust clinical trial data. While the biological rationale is plausible and early findings are promising, more rigorous human studies are needed to confirm safety and efficacy. Thus, scientific interest and limited preliminary evidence support cautious consideration, but the overall evidence level is low (2/5).
