I was at a conference in London on drug and alcohol history. I go to these quite a bit. But this time they caught me on video.
To avoid seeming entirely self-promoting, I encourage you to follow the links to other interesting presentations at that conference. And just in case you’re wondering, the “James” to whom I refer in the paper, is James Kneale, who presented his paper immediately before mine. His presentation is also on this site, as are many others, and all better than mine, I’m sure.
