Which plant is the source for non-synthetic narcotics?

The source of non-synthetic narcotics is the poppy plant. This plant produces opiates, which are natural substances extracted from the seeds and sap of the poppy flower. Specifically, the opium poppy (Papaver somniferum) is renowned for its production of key narcotics such as morphine and codeine. These substances are directly derived from the plant and possess potent analgesic and sedative properties.

While cannabis comes from the Cannabis sativa plant and contains cannabinoids, it is classified differently than the opiates derived from poppies. Other options like cactus and cocoa, although they may contain psychoactive compounds, do not produce narcotics in the same category or manner as the poppy. Thus, the poppy plant is uniquely recognized in pharmacology for its role in the production of non-synthetic narcotics.
