Free rehab centers in Arizona offer addiction treatment and substance abuse counseling for people living in such cities as Phoenix, Tucson and Flagstaff. For people who are homeless or who do not have the financial resources to seek help in a private setting, state-financed programs enable recipients to gain the therapy they need to facilitate recovery. Rescue centers, the Salvation Army and not-for-profit drug rehab sites make it possible for anyone who is residing in the state to obtain the help they need to overcome a substance abuse problem or a related disorder.
