If Someone Is Using Methadone, Can They Get High of Other Drugs?

Question by Allyson: If someone is using methadone, can they get high of other drugs?
My uncle is an outpatient in methadone treatment. But acting very hyper and running around a lot. Is this normal? Or could he also using something else?

Best answer:

Answer by nurse
Methadone doesn’t make you hyper. It could simply be that he’s not always ‘low’ from heroin use any more, and seems hyper because of it. Generally, people who like ‘downer’ drugs don’t switch to uppers like that, but I don’t know your uncle, so anything is possible.
