The Sitting & Discussion Group for People in Recovery is hosted by the San Francisco Zen Center. It is difficult to find info about it on the SFZC web site, but if you first go to the News section and then from there search on recovery, you will start to find articles related to recovery and buddhism, and a nice article titled Sangha in Recovery that talks about the weekly meeting. If you can't find that article, this link might find it. It is easier to get the meeting details at the Buddhist Recovery Network site. Searching the SFZC web site on the word recovery may turn up other workshops or events related to 12-steps and recover. There are also some good articles on the SFZC web site which were probably originally sponsored or written by members of the recovery group. Searching doesn't seem to find them any more, but they seem to still be available at these links:
