Logan finds a couple of methadone dosage units at the shooting gallery, and later when they arrest Maya at the methadone clinic the nurse gives her brother his methadone and just lets him walk off with it. When someone is being treated at a methadone clinic they are not allowed to take their medication with them, the methadone has to be administered on site, the nurse dispensing the methadone is required by law to ensure that the patient drinks and swallows all of it before allowing them to leave. This is to ensure that the patient is complying with their prescribed regiment and is not abusing or diverting their methadone.
