Central Jersey Intergroup (CJI) is an Alcoholics Anonymous service entity. It is made up of the A.A. groups in the Trenton, NJ and surrounding areas. CJI provides local services to alcoholics in the area that individual groups are not able to provide, such as meeting lists and maintaining a 24 hour emergency hotline. Your Intergroup is often where the sick alcoholic first calls or shows up for A.A. help.
