Narcotics Anonymous (NA) membership is open to all drug addicts, regardless of the particular drug or combination of drugs used. When adapting AA’s First Step, the word “addiction” was substituted for “alcohol,” thus removing drug-specific language and reflecting the “disease concept” of addiction. Narcotics Anonymous provides a recovery process and peer support network that are linked together. One of the keys to NA’s success is the therapeutic value of addicts working with other addicts. Members share their successes and challenges in overcoming active addiction and living drug-free, productive lives through the application of the principles contained within the Twelve Steps and Twelve Traditions of NA. These principles are the core of the Narcotics Anonymous recovery program. Narcotics Anonymous itself is a non-religious program of recovery; each member is encouraged to cultivate an individual understanding—religious or not—of the spiritual principles and apply these principles to everyday life.
