Cannabis for Refractory Psoriasis-High Hopes for a Novel Treatment and a Literature Review

Although the exact pathophysiology of psoriasis is not entirely understood, immune system and its interaction with nervous system have been postulated and investigated as the underlying mechanism. The interaction between these two systems through cholinergic anti-inflammatory pathway and also endocannabinoid system, may suggest cannabinoids as potential addition to antipsoriatic armamentarium.
