    The very fast death factor is a very potent weapon that has still not been addressed. We stand as the voice of the people and demand to add Anatoxin-a (C10H12NO) to the banned chemicals list. Anatoxin-a targets the nervous system thus making it virtually impossible to stop it since it targets the body in a matter of moments. One gram of this chemical can kill 350 people and unlike many other poisons this chemical works fast to kill. Even before the eventual death by respiratory paralysis that…
