Hey I don't know if this was posted before but I found an Episode of Penn & Teller's Bullsh*t that addresses 12 step recovery programs. I have the link to part 1 here, parts 2&3 you can find from there. They mention Nal briefly at the end, and there is nothing contained in the show I didn't already read, but it was nice to see someone did a show on it.
