Detoxification Standards
Programs providing detoxification services (dispensing an opioid agonist medication in decreasing doses) may offer this service for short-term (up to 30 days) or long-term (from 31 to 180 days) durations. Detoxification services are intended to help individuals reduce or eliminate their use of illicit drugs. Admission criteria are followed, a physical evaluation is conducted, and individuals are provided written, informed consent. Written procedures describe the impact of detoxification on those with co-occurring disorders and health needs, as well as how detoxification is provided to individuals prior to their incarceration. If detoxification services are provided to women, the program provides counseling specific to women's issues and assigns specialized counselors. If women are pregnant, adherence to accepted medical standards are ensured and appropriate referrals are made. Counseling services are provided during both long- and short-term detoxification programs.

Medically Supervised Withdrawal
Medically Supervised Withdrawal (MSW) is the term used for detoxification from methadone, since methadone itself should not be considered a toxic substance. This procedure is designed to eliminate the withdrawal syndrome. MSW may occur for a variety of reasons, and it should be physician-directed, be documented appropriately, and include supportive services and/or referral if necessary.

Outpatient Treatment
Although there are a variety of core programs to choose from in the CARF standards manual, outpatient treatment is the most common form of service delivery for opioid substitution treatment (methadone maintenance) in the United States.
