Drug warriors such as Andrea Barthwell and David Murray have argued strenuously that cannabinoid-based pharmaceuticals such as Marinol and Sativex are completely different from marijuana. Theyâve bristled at Rob Kampiaâs claims that Sativex is "liquid marijuana" and theyâve long used the availability of Marinol as an excuse to arrest patients who prefer cultivated marijuana instead.
Whether extracted or synthesized, THC-based medicines donât include anything not present in the plant itself, so itâs ludicrous to argue that one can be medicinal and the other canât. Yet theyâve done exactly that. Afterall, if this stuff is medicine, it sure as hell isnât marijuana.
Thus I was rather surprised to come across this Google ad:
