Alcoholics Anonymous practices a singleness of purpose, and that is to carry the message to the alcoholic who still suffers.
Alcoholics Anonymous is an international fellowship of people who experienced a problem with drinking. It is completely nonprofessional, informal, self-supported, apolitical, diverse, and worldwide. There is no requirement for AA membership and there are no dues or fees. Anyone who believes they may have an alcohol problem is free to join the fellowship. There are no forms to sign, no attendance to take, and no declarations of allegiance to be made.
“Our membership ought to include all who suffer from alcoholism. Hence we may refuse none who wish to recover. Nor ought AA membership ever depend on money or conformity. Any two or three alcoholics gathered together for sobriety may call themselves an AA group, provided that, as a group, they have no other affiliation.”
