opium

 [o´pe-um]
the air-dried milky exudation from unripe capsules of Papaver somniferum and P.album (the opium poppies). It contains some 25 alkaloids, the most important being codeine, morphine (from which heroin is derived), noscapine, papaverine, and thebaine, all of which can be used for their narcotic and analgesic effects. Opium is poisonous in large doses; because it is highly addictive, production and cultivation of the poppies is prohibited by most nations by international agreement, and its sale or possession for other than medical uses is strictly prohibited by federal, state, and local laws. See also drug abuse.
