For instance, the term addiction specialist refers to trained medical doctors. States regulate most addiction recovery jobs, and state licensing protects patients’ health and privacy.
Licensed addiction recovery specialists have completed specific amounts of education, testing, and supervised work to ensure they have the experience and education necessary to treat clients while keeping them safe.
