Morphine is isolated from opium in large quantities (over 1000 tons per year), although most commercial opium is converted into codeine by methylation. Morphine acts as an anesthetic without decreasing consciousness, and it is one of the most powerful analgesics known.
Morphine and heroin are both well-known narcotic drugs. They are quite similar substances, with enough overlap in molecular structure, mechanism of action and range of effects to blur the distinction between the two without closer scrutiny.
