Substance use disorders are classified as “chronic diseases,” and as such, they can be treated, but they cannot necessarily be cured. As treatable conditions, substance use disorders respond to therapy. Substance use disorders require that your physician or therapist develop the right therapy for you. Since the first treatment that your physician or therapist develops for you may not be the right one, the physician or therapist will continue to change your therapy until you are both satisfied that you have found the correct one. The treatment of substance use disorders is an ongoing, long-term process, so you can expect to be in therapy for your substance use disorder for several years.
