Sorry, but alcohol prohibition did not work and was instrumental in fueling the rise of organized crime (does that ring any bells?).

I happen to believe the War on Drugs (prohibition v2) is an even bigger mistake than the first one, which also ignores why it came to be: v1 prohibition enforcers needed something to do and there was a growing problems with an "uppity" segment of society that needed to be put in its place. The history of it is horrifying; and the current implementation of it is horrifying as well.

So legalize it all. Regulate the advertisement/promotion/access/purity, etc. It's going to happen one way or another and pushing it into the shadows only makes it worse.

So let the gambling happen but keep it on a short leash.
