Opiate

Opiates are a class of drugs that are derivatives (in the broadest sense of the word) of opium. These include two groups of alkaloids: phenanthrenes[?] and papaverines[?]. Opiates in the narrower sense of the word are only the phenanthrenes[?]. Opioids are synthetic drugs that are chemically unrelated to the opiates, but act on the same receptors in the central nervous system and have similar clinical effects.
