Narcotics Anonymous sprang from the Alcoholics Anonymous Program of the late 1940s, with meetings first emerging in the Los Angeles area of California, USA, in the early Fifties. The NA program started as a small US movement that has grown into one of the world's oldest and largest organizations of its type.
Today, Narcotics Anonymous is well established throughout much of the Americas, Western Europe, Australia, and New Zealand. Newly formed groups and NA communities are now scattered throughout the Indian subcontinent, Africa, East Asia, the Middle East, and Eastern Europe. Narcotics Anonymous books and information pamphlets are currently available in 41 languages.
Reference to NA in Canada can found as early as 1954 but the fellowship did not take root in Canada until the early 60's but saw the most significant growth in the mid 80's with the release of the Narcotics Anonymous basic text.
