No-go: Naturally occurring alkaloids derived from the juice of the opium poppy plant such as morphine and codeine. The term opiate refers specifically to these substances. Morphine, the prototype of opioid analgesics, is a full "pure" agonist of the mu receptor and major narcotic analgesic. Codeine is minor narcotic analgesic. They are both in the same phenanthrene class. Hope it helps.
