Alcohol is a mind altering drug that causes more harm and misery on this planet than any other imbibed substance. Heroin is 600 times cheaper now than it was in the 70's and it's easier for a kid to get heroin than it is alcohol since drug dealers aren't carding people before they deal. When you criminalize a substance, you create two things: criminals and a black market. Since it's a criminal enterprise, then the criminals set the prices, the quality, the quantity, and they police and maintain their criminal enterprise with force. The profits from a black market enterprise are huge and there are tons of people willing to risk it for the money so every time you shut down one criminal, there are plenty more willing to fill that void and make that money. Look, just watch Penn & Teller's Showtime series episode entitled "The War On Drugs" - they did the research and didn't rely on some faceless therapist that obviously has no idea what he's talking about.
