The Circle of Sisters Women’s Convention of Narcotics Anonymous was started in Portland, Oregon by a group of recovering addicts who had a vision of an annual convention for the women of our fellowship. The first convention, held in February 1998, was called the Pacific Northwest Women’s Convention of Narcotics Anonymous #1.
At that time, the organizers anticipated the convention would become an ongoing tradition in the Pacific Northwest. COS quickly outgrew its origins, however, and the second year the words 'Pacific Northwest' were dropped. In its third year, COS ventured far from its roots, all the way to Houston, Texas. And in its fourth year, COS became an international NA convention by being held in Vancouver, Canada.
At the third COS, a decision was made to form a COS AdvisoryCommittee to help provide continuity as the Circle of Sisters grew and traveled further afield. And at the fourth convention, the first version of these Guidelines was approved.
