Opiates List Categories. The natural drugs contained on the opiates list come from the alkaloid materials found in the opium poppy seed plant. Opium poppy seed plants contain a high concentration of morphine-derived alkaloids, which accounts for why morphine is one of the strongest opiates in existence. Codeine-derived alkaloids make up the second highest concentration.
