Ethical Question

[Iceaxe]

So the other day an old acquaintance offers to trade me $200 in food stamps for $100 cash.

Here are a few more details.... I know the cash is going to be used to buy drugs, the guy is a meth head and his wife is a crack whore. They have no kids so I'm not taking food out of the mouth of babes. If I don't take the deal than someone else will. With the amount of taxes I pay it's really my money to begin with. Food stamp boy offered to go down and buy the food I pointed out and I'd just give him the cash after, this would allow me to avoid the embarrassment of using food stamps and would be slightly more legal..... while the guy is a druggie I do know it’s not a setup, he just wants cash to go buy more drugs.

What would you do?
