If Montel Williams really trusted refined cannabis as medicine he'd have instituted a therapeutic regime based on regulated application by conventional methods (pill, injection, patch) of ONE purified element (THC) in defined dosages.. with a system of measurement of results and as with all powerful narcotics, a plan to wean the patient off of dependence.
None of these things were of interest to Montel, who is steeped in the 'smoking' culture of weed, with its 60 odd noxious ingredients (none of which have been tested) and really just wanted to get high.. permanently. Neither he nor the marijuana industry is interested in research or therapy.. that's just part of the marketing pitch.
