Opiates List Categories. The natural drugs contained on the opiates list come from the alkaloid materials found in the opium poppy seed plant.

Codeine-derived alkaloids make up the second highest concentration.
Print. Originating from the poppy plant, codeine and morphine are examples of naturally-occurring opiates which provide pain relief and depress the central nervous system. Semi-synthetic opiates are derived from compounds found in the poppy plant which include hydrocodone, oxycodone, hydromorphone and oxymorphone.The term âopioidâ refers to drugs that are chemically synthesized to mimic the physical effects of pain relief seen with opiates.rint.
