Just weeks after Miley Cyrus thrust salvia into the national spotlight, all eyes are once again focused on the legal (in some states) hallucinogenic drug with news that Arizona shooter Jared Loughner was a user — leading many to question the drug's potential role in the Jan. 8 deadly shooting.

According to ABC News Radio, a high school friend of Loughner's named Zach Osler claimed Loughner was big into drinking and drugs in his teenage years. One of his drugs of choice was the legal hallucinogen, salvia.  

"He would say he was using it and he would talk about it and say what [it] would do to him and I was like, 'Dude, that's screwed up,' " Osler told ABC News Radio.  

So did salvia play a role in Loughner's eventual decision to open fire on U.S. Congresswomen Gabrielle Giffords and other innocent bystanders at the Congress on the Corner event in Tucson?  

According to experts, salvia produces an intense high lasting less than half an hour. And while it is sometimes linked with "dissociated reality," it is also associated with highly impaired mobility, which would have made it difficult for Loughner to even get up and walk let alone aim and fire a gun.

So it's unlikely, but not impossible.
