I remember when that episode aired. The office radio is usually tuned to NPR and all of the smokers listened intently while the resident anti's skin probably crawled. (She left half way through. I think the Klein interview was too much for her) When the show was over, there was a mass exodus of smokers to go outside and indulge.
I haven't explored all of the smokingfeelsgood site yet, but I'm intrigued by what I have seen. Parts of it are vaguely reminiscent of the old smoking by Denise site.
