About Salem Comprehensive Treatment Center in Salem, OR Salem Comprehensive Treatment Center (CTC), located in Salem, Oregon, offers medication-assisted treatment (MAT) to adults age 18 and older of all genders who are struggling with opioid use disorder. There are methadone clinics that offer only one type of medication as part of MAT, but our Salem center gives four options. Depending on what we determine is the proper medication and dosage for you after a thorough preadmission examination, we may prescribe naltrexone, methadone, Suboxone, or buprenorphine. Research shows that MAT gives a person a better chance at successful long-term recovery and decreases their risk of relapse.
