I am not going to agree with the police on the decision that the man was on" Bath Salts" I would not even begin to say he was not on any drug, however, the only real chemical that can transform a live person into a raging zombie like state would be a neurotoxin.
This has been proven for years. Back when a real zombie was photographed in 1933 and the hyper public would believe that there was voodoo magic they discovered that it was a neurotoxin which destroyed the right and left side of the brain leaving only the frontal lobes. The frontal lobes are aggression and instinct.
The term Zombie actually means a brain dead comatose state.
Haitian Zombie Powder
Davis traveled to Haiti at the request of Dr. Nathan S. Kline, who theorized that a drug was responsible for Narcisse's experiences as a zombie. Since such a drug could have medical uses, particularly in the field of anesthesiology, Kline hoped to gather samples, analyze them and determine how they worked.
Davis learned that Haitians who believed in zombies believed that a bokor's sorcery -- not a poison or a drug -- created them. According to local lore, a bokor captures a victim's ti bon ange, or the part of the soul directly connected to an individual, to create a zombie. But during his research, Davis discovered that the invoker used complex powders, made from dried and ground plants and animals, in their rituals.
Davis collected eight samples of this zombie powder in four regions of Haiti. Their ingredients were not identical, but seven of the eight samples had four ingredients in common:
One or more species of puffer fish, which often contain a deadly neurotoxin called tetrodotoxin
A marine toad (Bufo marinus), which produces numerous toxic substances
A hyla tree frog (Osteopilus dominicensis), which secretes an irritating (but not deadly) substance

If the hospital in Jacksonville, FL have any sense they will try to do blood work for any kind of Neurotoxin. The only way a zombie apocalypse, told by the CDC website, could happen is if humanity refuses to realize that our bodies are an organic machine and it is only as good as we have taken care of it. Time to question authority. Time to question our rights and make our government responsible by making them fix our country's issues. make them be accountable.
