Today I learned the difference between words „opiates” and „opioids” :
“Opiate is a term classically used in pharmacology to mean a drug derived from opium. Opioid, a more modern term, is used to designate all narcotics, both natural and synthetic, that bind to opioid receptors in the brain (including antagonists).[1] Opiates are alkaloid compounds naturally found in the opium poppy plant Papaver somniferum.[2] The psychoactive compounds found in the opium plant include morphine, codeine, and thebaine. All opioids, like opiates, are considered drugs of high abuse potential and are listed on various "Substance-Control Schedules" under the Uniform Controlled Substances Act of the United States of America”
