Honestly I have no clue, ever since I was like 13 I spent pretty much all my money on drugs. Now I had to grow up and pay rent, bills, car payment, food, etc. but the rest goes towards drugs.
I suppose I'd just live in a slightly nicer house, drive a slightly nicer car, with a TV that's a little bit bigger, clothes that are a little bit nicer, etc. More importantly I would probably work a lot less, since drugs are what motivates me to work as much as I do.
