Drugs play a huge role in the world -- I think they would a great addition to the Civ world. Just think about how much the opium trade affected the world, or how much money drugs make in a year. Drugs could function as trade goods that can be considered illegal or not legal by Civ's. This of course would bring in a lot of neat possibilities for late-game dynamics, like for example, you could vote to make drugs legal or illegal in the UN. They'd also have a yet-to-be-seen unique function in a Civ game, where if they are traded illegally, could , I don't know , give your Civ more happiness but increase corruption/maintenance costs. Or if they are traded legally, could generate big money but lead to productivity loss and other Civs perhaps not liking you. Hrmm what do you guys think? Too controversial maybe? Like it or not drugs that are classified as illegal -- personally I don't differentiate much between something like Ritalin or OxyContin than say, cocaine or marijuana from a moral stand point -- play a huge role in the politics of today world. The current Afghan situation, or the Mexico-US situation (actually US and all of South America pretty much) are very important political topics.
