Heroin

Heroin is a highly addictive and illicit opioid synthesized from morphine, a natural substance extracted from the opium poppy. Once it enters the brain, heroin is converted back into morphine and binds to mu-opioid receptors. This action blocks pain signals and produces an intense wave of euphoria, followed by a state of deep relaxation and drowsiness. These powerful reinforcing effects are what make heroin so addictive. Chronic use leads to profound physical dependence and severe withdrawal symptoms. As a potent central nervous system depressant, overdose is a major risk, often causing fatal respiratory failure.
