Another cautionary tale about the dangers of bath salts...this one is a son's violent attack on his own parents!

Brian McCullagh's father says it happened in Roswell over the weekend.

He says his son is addicted to the addictive salts, even though a recent Georgia law bans their sale.

"It totally changed his personality," says the father, Brian McCullagh.  "He would get violent.  He'd be hearing voices.  He would try to pick fights with me."

McCullagh says his son got the salts at a "Smoke 911" store on Holcomb Bridge Road--and used them right outside.  But clerks later told a Channel 2 Action News staffer the store doesn't sell the salts.

Georgia's poison control calls use of the salts a "growing problem.  Seem to be getting more and more calls in the last few months," Poison Control Director Gaylord Lopez tells Channel 2 Action News.

And he cautions parents, "These stores aren't going to be advertising them.  It's usually a word of mouth kind of deal".

The salts are illegal in half-a-dozen states.  They're usually snorted, though they can also be injected or eaten.  Users often develop high blood pressure, anxiety, or psychosis.

McCullagh says he believes the store should be prosecuted.  Roswell police are investigating.
