When I saw this graphic it occurred to me that the main reason why alcohol isn't illegal in America is because we tried to ban it at a time when we lacked the ability to enforce that ban. I think we'd be able to do a very good job of it today. We actually do a pretty good job of suppressing drugs, when you think about it. Which is impressive when you consider that drugs, by and large, are considerably easier to conceal, ship and store; plus it's pretty easy to detect when someone has used alcohol.
