answer:Most likely. Expiration dates do not automatically turn a drug or product bad overnight. Most medications can last many months after their expiration dates, and may lose some potency but will not hurt you. Now I am NOT familiar with morphine, so to be sure check with a pharmacist. If the medication is in liquid form rather than tablet, I do not know, so do NOT take my word for it, however, generally speaking, most pill/tablet forms of medications can outlive their shelf lives by lengthy periods of time.
