I often wonder why they never explore it either. They tried one version (cannabinoid) CBD. We tried CBD as well. It didn't work. So we moved to THC, and now also CBG. He's been on it for nearly 3 years. In that time we have discontinued 2 pharmas, and the 3 remaining ones he is on we have been at the same dose for YEARS. That alone was basically unheard of for him. Oh, and he sleeps like a champ. Maybe they don't want to put in all the work of researching strains, terpenes, and making tinctures/plant matter capsules/edibles, or learning about this other wonderful cannabinoid and what it can truly do.Too bad they don't explore it as they live in a legal state that actually has autism listed as a qualifying condition. We considered moving to another state for this very reason. Medical cannabis has less negative side effects vs synthetic drugs.
