If you're referring to the isolation of specific cannabinoids, like non-psychoactive CBD, CBG, CBC, CBN; I support this. There is some early research with these compounds that is promising for medical uses.
The desire to concentrate or increase THC amounts is no different than higher alcohol or caffeine beverages, IMO. Always a market for people chasing the tail of the dragon. The danger is course is people without the high tolerance dosing themselves more than they can handle.
