methadone is part of a class of drugs called opioids. German doctors made it during World War II. In the United States, doctors used it to treat people with extreme pain. Today, you can also get it as part of a treatment program for an addiction to heroin or narcotic pain medication.

Although it is safer than some other narcotics,

moet uw arts goed in de gaten houden terwijl u methadon gebruikt. Het gebruik ervan kan leiden tot verslaving of misbruik.
