Drug and alcohol rehab services are accessible in languages other than English from treatment facilities with bilingual staff and from addiction treatment educational services available in other languages. Addiction treatment programs in Rex which provide rehabilitation services in other languages will give group counseling or therapy in those languages, and will provide either hard copy or digital educational materials accessible in those languages as well. The most prevalent "other-language" services available are Spanish language rehabilitation services, because Spanish speaking clients constitute the highest number of other language speaking individuals in need of rehabilitation.

Finding such a program when English is not your native tongue can be helpful for more reasons than the difficulties with verbal communication, because there are also cultural/social differences and other things to consider. When treating someone who speaks another language the treatment center staff must not only be able to communicate with them easily and expressively, but also identify with their culture, background, and specific beliefs and values that should be considered when attempting to treat their substance abuse problem. Individuals looking for a rehab program delivered in other languages will want to make certain the facility has staff that are capable of delivering services in their native language but who are also capable of identifying and understanding their culture and heritage.
