My friend Amelia and I wrote the first of a two-part essay on how existing research methods into smoking cannot result in an understanding of vape, or new technology generally. Amelia is a PHD candidate at the University of Waterloo, Canada. She has a particular interest in the social, political and cultural dimensions of expert knowledge-making in science and technology. She's one of the most interesting thinkers I know, so writing this with her has been a real privilege. Have a read! Is vaping sticky enough? And how can we tell?
