Gil L. - NA Speaker - "Basic Text, Clean Life"

"Narcotics Anonymous (NA) describes itself as a "fellowship or society of men and women for whom drugs had become a major problem" following the Twelve Steps and the Twelve Traditions developed by Alcoholics Anonymous, and it is the second-largest 12-step organization.

As of May 2010 there were more than 58,000 NA meetings in 131 countries.

Because no attendance records are kept, it is impossible to estimate what percentages of those who come to Narcotics Anonymous remain active in NA over time. The only sure indicator of the program's success in attracting members is the rapid growth in the number of registered Narcotics Anonymous meetings in recent decades and the rapid spread of Narcotics Anonymous outside North America.

In 1978, there were fewer than 200 registered groups in three countries.
In 1983, more than a dozen countries had 2,966 meetings.
In 1993, 60 countries had over 13,000 groups holding over 19,000 meetings.
In 2002, 108 countries had 20,000 groups holding over 30,000 meetings.
In 2005, 116 countries had over 21,500 groups holding over 33,500 weekly meetings.
In 2007, there were over 25,065 groups holding over 43,900 weekly meetings in 127 countries.
In 2012, there were over 62,700 meetings worldwide in over 142 countries"
