Right, but if you were to abide drug laws like most people, your mood wouldn't matter. You'd have to pick beer every time. By keeping the competition in the underground, they assure that if you go to a bar, you will only be able to buy beer there. If you go to a baseball game, there will be a beer man but no joint man. The law abiding citizen has only one choice when it comes to getting wasted, which might otherwise be split into two industries.

However, it could be argued that if weed were legalized, the artificially inflated prices of an illegal product would disappear, and people who use both would have more money to invest in beer.
