First meeting of Narcotics Anonymous takes place, in Southern California.

Narcotics Anonymous (NA), founded in 1953, describes itself as a "nonprofit fellowship or society of men and women for whom drugs had become a major problem." Narcotics Anonymous uses a 12-step model developed for people with varied substance use disorders and is the second-largest 12-step organization, after 12-step pioneer Alcoholics Anonymous.
