Methadone is a synthetic opioid used for pain and to treat addiction in patients with opioid dependence. It is chemically closely related to heroin and morphine and has many of the same effects, yet, if used correctly, it is medically safe. Because it is relatively inexpensive, can relieve narcotic craving, blocks the euphoric effect associated with opioids, and when properly administrated is non-sedating, it is excellent for treating addiction and allowing addicts to maintain a normal lifestyle.
