This article at the 2006 National Conference on Injecting Drug Use was quite interesting, especially the lecture given by Llewellyn: http://www.mesomorphosis.com/article...conference.htm
There's a bunch of other lectures up for listen on the exchangesupplies.org site, all of them worth hearing.
Has anyone else listened to any of these? I was hoping to get some feedback with regards to the various ideas and standpoints.
