As with most illegal drugs, Heroin use has both short-term and long-term effects. Whether injected, snorted or smoked, heroin will begin to affect the body's central nervous system almost immeidately after it is used. Because heroin suppresses the central nervous system, the user experiences "cloudy" mental function. Users will begin to breathe at a slower rate and their breathing can reach a point of respiratory failure.
