It is an agricultural crop which is mainly cultivated for its seeds and also for alkaloids produced by them. There are many alkaloids present in it namely morphine, codeine etc.

Complete answer:
Opium was grown for its medicinal properties. The traditional method of harvesting involves making a small cut on the immature seed pods through which a liquid latex would leak and then dry. This dried latex is called raw opium. It is mainly harvested for its latex and from this opium all other alkaloid compounds are extracted. Apart from the immature seeds, the poppy straw is also used for extraction of other alkaloids like morphine and opiates. The latex contains almost about $12\%$ of morphine. Here the paddy straw includes all other parts of the plant, mainly crushed capsules without seeds. This process by which opiates are extracted from the poppy straw is by the poppy straw method and was first invented by Janos Kabay. The poppy straw is used for commercial production of morphine which can be further processed to produce heroin. As the opium is mainly obtained from dried latex which is obtained from the unripe capsule.
