Methadone will not result in a positive test for commonly abused opiates such as morphine or heroin. The only way for a company or other organization to detect methadone is to test for it specifically – which is not a common practice. Also, it is important to remember that people who are participating in approved methadone maintenance programs are not abusing an illegal drug – they are taking legal medication with the approval and supervision of a qualified healthcare provider. Methadone patients are covered under the Americans with Disabilities Act (ADA) – which means that methadone use cannot be used to deny employment.
