***** To join INSNA, visit http://www.insna.org ***** Dear Danah, I have done research on the social networks of teenagers in relation to their substance use. It may be relevant to your needs. Some papers you could look at in the journal Social Networks which is available on-line. Kirke, D. M. 2004 "Chain reactions in adolescents' cigarette, alcohol and drug use: similarity through peer influence or the patterning of ties in peer networks?" Social Networks, 26, 1, 3-28. and Kirke, D. M. 1996 "Collecting peer data and delineating peer networks in a complete network", Social Networks, 18, 333-346. Hope that you find them helpful.
