Papaver bracteatum, also known as the Iranian poppy, is a sturdy perennial poppy with large deep red flowers up to 8 inches (20 cm) across on stiff stalks up to 4 feet (1.22 metres) high with a prominent black spot near the base of the petals. It is related to the commonly cultivated oriental poppy, Papaver orientale.
Non-horticultural use of this species is for the production of thebaine, which is commercially converted to codeine and semi-synthetic opiates. Papaver bracteatum does not contain morphine, codeine or other narcotic phenanthrene-type alkaloids.
United States domestic cultivation of P. bractaetum was proposed by president Richard Nixon's Office of Management and Budget in the early 1970s as an alternative to Turkish opium poppies, which the administration was attempting to eliminate. This was because P. bracteatum does not contain morphine, which was (and still is) illegally converted to heroin, but is high in thebaine for legal codeine production, which was in crisis at the time because of the dwindling Turkish supply. However, US government scientists feared Bentley compounds, opioids thousands of times more potent than heroin, would replace heroin in the US.
