The Joint Meeting on Adolescent Treatment Effectiveness (JMATE) - the only national conference specifically devoted to adolescent substance abuse treatment -- is coming up in December. JMATE has issued a call for papers, registration opens June 1st, and now you can follow JMATE on Facebook.
Reclaiming Futures is one of the co-sponsors, but even if it weren't, I'd be encouraging you to go. I've been to several JMATEs and they were all excellent, informative events. (Also, it's great to be at a treatment conference and never have to ask after a presentation, "Say, does your research apply to teens as well as adults?")
