Marijuana legalization used the same strategy: medical first, then complete. The technique works. The other technique of "Oh yeah, I want it for fun so you should let me do it" has been tried for eons and got nowhere. You can come up with all the theory, but one technique worked and the other didn't, so I'm not interested in the theory.
Fake science it's going to be. The people who hate it don't have the ability to tell that it's fake.
