Let's examine each plant:

• Papaver Somniferum: Commonly known as the opium poppy. It is the source of opium and its derivatives like morphine, codeine, and heroin. It is native to the Eastern Mediterranean region and Asia Minor, not America.
• Erthroxylum coca: Commonly known as the coca plant. It is the source of cocaine, a potent stimulant drug. This plant is native to the Andean regions of South America. South America is part of America.
• Cannabis sativa: Commonly known as hemp or marijuana. It is the source of cannabinoids like THC and CBD. It is widely believed to be native to Central Asia or South Asia, not America.
• Atropa belladona: Commonly known as deadly nightshade. It is a source of tropane alkaloids like atropine, scopolamine, and hyoscyamine, which have medicinal uses but are also toxic. It is native to Europe, North Africa, and Western Asia, not America.
