Substance abuse treatment programs in Maryland are offered to low-income individuals or homeless people for free. Programs sponsored by rescue missions and the Salvation Army allow participants to overcome their drug addiction issues by combining drugs that suppress cravings and behavioral therapy. Residents living in such cities as Baltimore, Columbia and Germantown can also sign up at not-for-profit, low-cost drug rehab programs that operate on a sliding scale. Regardless of the program you choose, the help is there if you need it, whether you require drug counseling and therapy or you know of a family member or friend who could benefit from the services offered at an addiction treatment residence.
