An oblique reference to the Miami Cannibal Attack which police claimed was the result of the assailant being “high on bath salts” at the time of the incident. Toxicology failed to corroborate the claim, but it stuck in the anti-drug media and became a recurring urban legend of sorts that DARE officers would repeat to credulous kids.

Edit: I think the bath salts as a cause has been disproven but the story remains.

PCP, so not exactly the same as bath salts but similar.
