I live with my parents, and I am balancing getting out of high school (fell a little behind lol) while looking for job...so I get very little income since we're middle class/upper-lower class. Any money I get I save it for as long as possible, but I end up finding a hook, or get tempted to dex when I am out with friends.
I say 70% of my income/money goes to drugs, but that's a lot less drugs than you would imagine as explained before =)
