“We have found it helpful to have a sponsor and to use this sponsor. Sponsorship is a two-way street. It helps both the newcomer and the sponsor. The sponsor’s clean time and experience may well depend on the availability of sponsors in a locality. Sponsorship for newcomers is also the responsibility of the group. It is implied and informal in its approach, but it is the heart of the NA way of recovery from addiction—one addict helping another.”
I understand this to say that the group should sponsor the newcomer until he finds a sponsor. Above, I use “he” because I’m male and don’t try to look after female newcomers!
