I think investing in coffee, liquor, beer, wine, might be a good thing, in the short run.
Try the Vice Fund. Good returns. No joke. The last things people will give up are cigs, alcohol and lottery tickets. As an added bonus, it invests in Military Defense, too. A little something for everyone, LOL!

Unless you're talking about direct investment in the production, manufacture, and distribution networks, your investment is likely to be confiscated by the state (it's for the children).
That's what made the Kennedys a force in American politics, BTW.
