I did some research on zombies in fiction because I was bored mindlessly. I then noticed Article 246 in the Haitian Penal code from 1835. It stated that administering a substance that induces prolonged periods of lethargy without causing death is considered attempted murder because of the fact that the person would be buried prematurely. This made me wonder if this chemical actually existed... or if this was just a typical Voodo myth.
