This might be a shot in the dark, but I highly doubt you've spent $100K on booze in your lifetime. Not only is there little to no chance you'd have that kind of money, but your also far too young to rack up that kind of tab by only drinking on the weekends, as much as it might be. I think you were half-way kidding when you said that, but I'm not too sure.

Either way, I'm 20, and haven't spent anywhere close to $100K on weed. I'd say somewhere around a couple thousand dollars, give or take. ~
