While it's not directly associated with Alcoholics Anonymous, Nicotine Anonymous applies that same 12-step approach to quitting smoking. It's not a religious or government organization, and it's free to join and attend meetings.
Nicotine Anonymous holds in-person meetings, as well as Internet and telephone meetings, to help support smokers who want to quit. Via the group's online search tool, smokers can find meetings in 46 states and in Washington D.C., as well as 38 other countries. If there isn't a meeting in your area, the organization also offers a "Meetings Starter Kit" for smokers who want to start a Nicotine Anonymous meeting in their area.
Along with the 12 steps, Nicotine Anonymous is based on "Twelve Traditions," which outline the group's mission and commitment to never become organized, never take money from outside organizations and never become a commercial group. While the Twelve Steps and Twelve Traditions do mention God a number of times, Nicotine Anonymous is emphatic in its literature that it doesn't promote any specific faith.
