If you have the National Geographic Channel, they are airing a show called "Pill Nation", it's from a series of shows called "Drugs Inc" VERY informative and interesting to watch. (I would assume you could watch this show on Hulu or one of those sites if you don't have this channel.) IMO this is a worthwhile hour long show to watch. Weather you want to learn about prices, the way that Americans are obtaining these medications, how widespread this "epidemic is" or are just curious to learn, this show has something to offer everyone.
I'm shocked at some of the things I'm learning by watching this show, but glad I stumbled across this program, it's very interesting!
