The opium poppy, Papaver somniferum, is the type of poppy from which opium and all refined opiates such as morphine (up to 20%), thebaine (5%), codeine (1%), papaverine (1%), and narcotine (5-8%) are naturally present and extracted from the poppy.

There are many varieties of this poppy species.

Colors of the flower vary widely, as do other physical characteristics (number and shape of petals, number of pods, production of morphine, etc.).

The seeds of the poppy are widely used as the popular "poppy-seed" found in and on many food items such as bagels, muffins and cakes.

The seeds can be pressed to form poppy seed oil, which can be used in cooking.

Opium poppy seeds contain negligible amounts of narcotics.

Possession of any part of Papaver somniferum other than the seed is outlawed in the United States and is listed as a Schedule II controlled substance by the Drug Enforcement Administration..
