What is synthetic methadone?

Umm, synthetic methadone IS methadone. Methadone is synthetic to begin with so to say what is synthetic methadone is like saying what is a human person. A person is a human LOL. So whoever is saying "synthetic methadone" has got something mixed up, because methadone is just methadone. While it comes in different forms (pills and liquid) it is all synthetically made and not natural.
