ReviewMedical cannabis: Another piece in the mosaic of autoimmunity?
Legalization of cannabis' medicinal use is rapidly increasing worldwide, raising the need to evaluate medical implications of cannabis. Currently, evidence supports cannabis and its active ingredients as immune-modulating agents, affecting T-cells, B-cells, monocytes, and microglia cells, causing an overall reduction in pro-inflammatory cytokine expression and an increase in anti-inflammatory cytokines. ⋯ However, contradicting results and lack of large-scale clinical trials obscure these results. Although lacking clinical research, in vitro and in vivo experiments in rheumatoid arthritis, diabetes type 1, and systemic sclerosis demonstrate a correlation between disease activity and cannabinoids.

The recent emergence of a multitude of synthetic cannabinoids (SCs) has generated a wealth of new information, suggesting the usefulness of state-of-the-art on lato sensu cannabinoids. By modulating a plurality of neurotransmission pathways, the endocannabinoid system is involved in many physiological processes that are increasingly explored. ⋯ Neurological and cardiovascular side effects observed after cannabinoid poisoning generally respond to conventional supportive care, but severe outcomes may occur in a minority of cases, mainly observed with SCs. The likelihood of severe abuse and addiction produced by SCs are of concern for the scientific community also interested in the potential therapeutic value of cannabinoids.

Scientific interest in serotonergic psychedelics (e.g., psilocybin and LSD; 5-HT2A receptor agonists) has dramatically increased within the last decade. Clinical studies administering psychedelics with psychotherapy have shown preliminary evidence of robust efficacy in treating anxiety and depression, as well as addiction to tobacco and alcohol. ⋯ Antiinflammatory effects may hold promise for efficacy in treatment of inflammation-related nonpsychiatric as well as potentially for psychiatric disorders. Serotonergic psychedelics operate through unique mechanisms that show promising effects for a variety of intractable, debilitating, and lethal disorders, and should be rigorously researched.
