Are morphine tabs (msir) more addictive than methadone?

MS and methadone: I disagree. Both are potent narcotics that can activate the disease of addiction in susceptible patients. The physical withdrawal from Methadone is more prolonged than the withdrawal from morphone but they both can activate addiction. Methadone is used in substitution therapy for other opiate addictions because it gets across the blood-brain barrier more slowly and causes less euphoria & sedation.
