What's sad is he's going to lose all $1300 of that cash (evidence *ahem*), and there's no way it was made in relation to the 20 pills of Xanax he had on him.
Probably made it selling coke.
OBLIGATORY EDIT: Since he's just a kid, I want to say that I'm totally joking. And although he's a Horn commit, I have no ill-will towards him. Every high school across America has a kid at school right now trying to move a few pills of Xanax which are just barbituates that simulate the feeling of being drunk without having to drink. That can be an attractive thing to kids that have trouble scoring alcohol.
However, Xanax can be a dangerous drug because it's commonly used in conjunction with drinking which amplifies the effects of both, and that can possibly lead to heart failure. On the other hand, half of soccer-mom America are taking Xanax and drinking a bottle of wine every night to cope with their failed dreams and lackluster marriages.
