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 adds, "Miley is a star and young kids are going to emulate her behavior."

Back in 2007, Adams tried to get salvia outlawed and classifed as a Schedule I controlled substance -- the same as LSD and marijuana. When the bill was voted down ... Adams settled for restrictions on selling salvia to minors. It is still legal in California for adults.

After seeing the video of Miley smoking the drug, Adams thinks this is the perfect time to bring back his failed bill: "It's time for state and federal governments to renew their push toward an outright ban."(via-tmz)Tweet
