It should come as little surprise that someone as demonstrably brilliant as Albert Einstein saw the idiocy of prohibition, and he had this to say on it:
The prestige of government has undoubtedly been lowered considerably by the prohibition law. For nothing is more destructive of respect for the government and the law of the land than passing laws which cannot be enforced. It is an open secret that the dangerous increase of crime in this country is closely connected with this.
The Federal government could learn a thing or two from Einstein. Namely, that marijuana prohibition and the war on drugs has been and will be for as long as it continues, a total failure.
