Cannabis has biological properties including immunomodulation and effects on excitototoxicity that suggest it could be useful in ALS. Evidence from small, non-randomized, unblinded animal studies suggest that it could potentially slow ALS progression, and anecdotal reports suggest that it could ameliorate troubling ALS symptoms. Given all this, ALSUntangled supports further careful study of cannabis and cannabinoids, the active ingredients contained therein. Natural cannabis, as a single agent, provides advantages similar to a multiple drug trial given its numerous mechanisms of action. A possible next step would be a small case series of well-characterized PALS using cannabis at controlled dosages that could potentially be monitored by blood levels of cannabinoids, compared to matched controls, performed in a geographic area where it would be legal.
