It's something we only expect to see in zombie movies, a naked man attacking another man, biting and eating parts of his face. But that bizarre and cannibalistic episode made headlines in Florida earlier this week.
People were tweeting last night that it was a mutant virus, and people had been quarantined.
But police say his actions were symptomatic of a drug-induced psychosis from a potent variant of LSD in bath salts, a condition that is landing a growing number of people in the hospital.

Armando Aguilar with the Fraternal Order of Police described the gore. "75 to 80 percent of his face was missing, and he was actually swallowing pieces of the man's face."
While police say they've never witnessed anything this extreme, they've recently seen similar cases of people with no clothes on acting violently after taking a new potent form of LSD. "Inside their body, their organs are burning up alive," Aguilar said. "They've reached a temperature where they're actually burning up, and it actually makes them take off their clothes."
In the emergency room, they've seen an increase of people suffering from psychosis for a variety of drugs. Emergency room physician Dr. Paul Adams said, "Cocaine and new LSDs ... they cause delirium, which means you don't make sense when you take them, and when you don't make sense and you don't control your emotions, you don't control your actions, you find yourself in circumstances you just don't want to be in."
During and after the recent Ultra Music Festival, Dr. Adams said he has seen the effects of a designer drug nicknamed "bath salts," which also causes body temperatures to spike."And then people don't drink water while they're taking it, so they become dehydrated," Adams said. "So, you mix dehydration with elevated temperature with loss of inhibitions and you have a life threatening combination. Mix for disaster."
Bath salts were banned in Florida in 2011, but new formulations have become dangerously popular. Adams said, "We've had several deaths earlier last year. We probably had our first death from bath salts being chased by the police and then all of the sudden just collapsing."
Some of the chemicals used to make bath salts were banned by the Senate last week.
Experts say dangerously little research exists about the drug's effect on users.
