You can’t get rid of pot by making it illegal. It is a plant that grows out of the ground. Even the most restrictive gun laws can’t keep guns away from criminals. Tobacco taxes don’t stop people from smoking they just make them buy cheaper cigarettes or get them from other states. Drug laws serve to make drugs expensive and many of the social ills of drugs are related to the expense of drugs. If you don’t want to smoke drink or do drugs then don’t. But those that do want to will do them regardless of legality.
The silly argument of an anarchist.
"You can't get rid of theft by making it illegal."
"You can't get rid of rape by making it illegal."
"You can't get rid of murder or assault by making it illegal."
Well, can you?
