Heroin is a highly addictive opioid drug derived from morphine, a natural substance extracted from the seed pod of the opium poppy plant (Papaver somniferum). It acts on the brainβs opioid receptors to produce intense feelings of euphoria and pain relief, but also slows breathing and can impair vital functions. Heroin is typically used by injection, inhalation, or smoking, and repeated use can lead to tolerance, physical dependence, and addiction, making it a dangerous substance with a high risk of overdose.
