Miley Cyrus is getting ripped by the dude who tried, unsuccessfully, to ban salvia -- the hallucinogenic herb sources say Miley was smoking last month during her 18th birthday party.
Anthony Adams -- a former CA State Assemblyman -- tells TMZ it was irresponsible of Miley to smoke salvia, which he says can make "you do incredibly crazy things." Adams added, "Miley is a star and young kids are going to emulate her behavior."
