From the UCSD blog:
It is with great sadness that we report that Dr. G. Alan Marlatt passed away this morning at 9:40 am. Alan was a kind and generous man with whom we had the pleasure of working the past couple years in conjunction with the training he and his team offered in Mindfulness-Based Relapse Prevention (MBRP) through UCSD. We are all quite saddened and shocked at the news of the death of this well-respected and widely honored psychologist, colleague and friend.
