Members take part in N.A. meetings by talking about their experiences and recovery from drug addiction. N.A. meetings are informally structured, held in spaces rented by the group, and are led by members who take turns opening and closing the meeting. N.A. meetings and other services are funded entirely from donations by addict members and the sale of recovery literature. Financial contributions from non-members are not accepted. Most N.A. meetings are held regularly at the same time and place each week, usually in a public facility.
Meetings vary widely in format.
