Learning tool of some sort

We were discussing substance abuse disorders the other week in one of my classes, and this was one of the slides that my professor had on his powerpoint. Let's just say he's way out of the box, which I love. So he always slips in crazy stuff to get us thinking and to make the class interesting. I thought this was pretty funny. But it also made an interesting point. Especially since in Georgia you can no longer buy cold medicine like on the shelf. You can only get it behind the counter at the pharmacist.
