Apparently, the zombie apocalypse has started. At least, that was the word from my teenage son. If you have a teenager in the house, or you read the news, you likely heard about the 31-year-old man in Miami who chewed the face off of a homeless man and was fatally shot by police when he wouldn’t stop his attack. Authorities are speculating that the attacker was high on bath salts. This isn’t the stuff you soak with in the bathtub; bath salts are a relatively new synthetic drug, and are still legal in many states.
