Opium

Opium, also known as poppy, was a plant that produced a latex that could be processed into a psychoactive drug.

The three main products of opium were morphine, laudanum, and heroin.

History
Opium was used as the base ingredient of the painkiller morphine since at least 1500 BBY. An opium farmer and later leading researcher of the Botanists' Guild named Laudamus also invented a tincture of opium and alcohol known as laudanum, which also had both medicinal and narcotic effects. Once it became clear that opium was gradually becoming more popular as a recreational drug than it was a medicine, opium and any related products were made illegal by the Galactic Senate in 400 BBY, around the same time that other plants such as cannabis and savorium were also illegalized. Nonetheless, opium survived on the black market - often in the form of heroin - where it remained popular among certain drug cultures on Republic/Imperial worlds. During the Imperial era, morphine was relegalized for use as a surgical anesthetic on backwater worlds where more common anesthetics were not accessible, though opium (and its other two main products, laudanum and heroin) remained illegal and heavily enforced.
