Are morphine and codeine the same?

No, morphine and codeine are not the same, although they are both opioids derived from opium. Morphine is a stronger pain reliever primarily used for severe pain, while codeine is generally used for milder pain and cough suppression. They differ in their potency, mechanisms of action, and potential side effects. Additionally, codeine is often metabolized into morphine in the body, but the two drugs have distinct clinical applications.
