Technically, Imodium (Loperamide) is an opiate, but it only binds to the mu receptors in the GI tract; and doesn't cross the BBB (Blood Brain Barrier) into the CNS (Central Nervous System) like other opiates do.
The natural drugs contained on the opiates list come from the alkaloid materials found in the opium poppy seed plant. Natural opiate drug types include â Codeine; Morphine; Oripavine; Thebaine; 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.
