Opiate
From Wacklepedia - The Free Encyclopedia
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.
