I've been one of the few people online stating that there was no evidence that the Miami 'zombie' who ate the face off of a homeless man was high on 'bath salts'. I also stated that I believed this was a cover-story that was given in order to calm the public down and prevent further inquiry into the possible causes of the incident. Now the official toxicology results have been released and the 'zombie' in question, Rudy Eugene, had marijuana in his system but not 'bath salts' or any other drug.
I think that this 'zombie' outbreak may in fact be a genuine mystery that needs to be properly investigated. If it turns out to be a virus then it may take decades before it is discovered and only if researchers are looking for it. Look how long it took for the HIV virus to be discovered and that was with teams of researchers looking for it. As far as I know, nobody is even questioning if there may be a pathogen responsible for these 'zombie' attacks.
Just for the record, pot gives you the munchies. It does not make you eat the face off of a human being.
