[Removed a bit too much hostility.]

I work with homeless people, many of whom have substance abuse issues. I've heard of all sorts of ways to get money for drugs (by the way, $2-4 isn't going to get that done, not even close) and have never heard of anything close to this ridiculous.

It's unbelievable. As someone else pointed out, with selling them you're looking at $40, not $2-4, for standing at an intersection or in a park. And you don't need to do it 30-40 times to get your fix.
