Substance abuse rehab services are available in languages other than English from rehab facilities with bilingual staff and from substance abuse recovery educational groups and services offered in other languages. Drug and Alcohol rehabilitation programs in Wana which deliver treatment services in other languages will give group therapy and counseling in those languages, and may provide either hard copy or digital educational materials available in those languages as well. The most prevalent "other-language" rehabs available are Spanish rehabilitation services, because Spanish speaking clients represent the highest number of other language speaking clients in need of addiction recovery.

Locating such a program when English is not your first language can be helpful for more reasons than the difficulties with language and communicating, because there are also cultural/social barriers and other things to consider. When providing rehabilitation for someone who speaks another language the treatment staff must not only be capable of communicating with them clearly and freely, but also know their culture, social customs, background, and specific beliefs and values that should be taken into consideration when attempting to resolve their substance abuse problem. Someone searching for a rehab program delivered in other languages will want to ensure the program has staff that are able to deliver services in their language but who are also capable of identifying and understanding their culture and social customs.
