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 ability to attract 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.
