HEROIN

Heroin, CSA Schedule I, is an illegal, highly addictive drug. It is both the most abused and the most rapidly acting of the opiates. Heroin is processed from Morphine, a naturally occurring substance extracted from the seed pod of certain varieties of poppy plants.
Heroin is usually injected, sniffed/snorted, or smoked. Typically, a heroin abuser may inject up to four times a day. Intravenous injection provides the greatest intensity and most rapid onset of euphoria (7-8 seconds), while intramuscular injection produces a relatively slow onset of euphoria (5-8 minutes). When heroin is sniffed or smoked, peak effects are usually felt within 10-15 minutes. Although smoking and sniffing heroin do not produce a "rush" as quickly or as intensely as intravenous injection, National Institute of Drug Abuse researchers have confirmed that all three forms of heroin administration are addictive.
