methadone vs "Methadone maintenance treatment":

Many people use methadone with the term "Methadone Maintenance Treatment" interchangeably.  This is not correct.  Methadone is a pharmaceutical agent with several uses including pain control.  On the other hand, Methadone maintenance treatment or MMT is a long-term program for those patients who have addiction/dependence to the opioid class of drugs such as oxycodone (OxyContin® or Percocet®), fentanyl, hydromorphone (Dilaudid®), heroin, morphine, codeine, etc.   MMT usually integrates non-pharmacological modes such as counseling, social work, and family therapy.
