"See what a number of new sins the '[moral] state' succeeds in creating in the course of failing to cure that of [substance abuse]. The man going [anywhere] has all the [substances] he wants with the following agreeable additions:

1. He has become a liar; calling things by false names and doing one thing while pretending to do another.
2. He has become a rebel and bad citizen, intriguing against the law of his country and the efficiency of its public service.
3. He has become a coward, shrinking through personal fear of consequences from acts of which he is not morally ashamed.
4. He has become a seducer and a bad example, bribing other men to soil their own simplicity and dignity.
5. He has become a most frightful fool, playing a part in an ignominious antic from which his mere physical self respect would hardly recover.
6. He has, in all probability, come much nearer than he would in any other way to having a craving for [substances]. For anything sought with such horrible secrecy and pertinacity has a great tendency to become magnetic and irresistible in itself; a sort of fetish. And all that brought about in order to prevent a man [the use of a substance] — which he gets after all. 

People who support such prohibitions can have no care for human morality at all!"

G. K. Chesterton [edited by Paul Dustin Nash]
