Using Methadone Safely
Methadone is a very powerful opioid medication, so it can be hazardous when combined with drugs such as alcohol,
sedatives, heroin and other drugs.
Other drugs like "speed" and cocaine can interact with the metabolism of methadone in unpredictable ways.
Some substance such as marijuana and club drugs like ecstasy are viewed as less harmful, but the use
of these drugs can alter mental functioning. Furthermore, using these drugs are illegal and can have potential harmful effects
in combination with methadone.
