all i know about methadone, is its a herione substitute..

if a herion addict wants to get off of herion, they go to a pharmacist and they get prescribe mathadone.. they take that instead of herion, its the same except they dont get fucked up on it like they would on herion, and its not dangerous.. then the pharmacist starts lowerin their dosage until they dont need it anymore
the only problem is, ppl get addicted to methadone instead

i may be wrong, but i dunno
