I must admit I am surprised by how effective THC-A can be in seizure disorders and Dystonia or Torticollis (severe neck spasms). So, it appears it has effects in both the central and peripheral nervous system.
As I have discussed many times over the years, THC is in it’s “acid” form until heated by smoking, vaping or cooking. This acid form is appropriately called THC-Acid or THC-A. THC in this acid form, similar to the juicing movement led by Dr. Courtney in northern California, is not psychoactive at all.
With my early experience with THC-A in the whole plant form, is actually less psychoactive than whole plant CBD.
