Years ago, thoughts of using a needle kept many potential heroin users at bay. Not anymore. Today's heroin is so pure, users can smoke it or snort it, causing more kids under 18 to use it. Kids who snort or smoke heroin face the same high risk of overdose and death that haunts intravenous users. Yet according to the annual Monitoring the Future national poll, more than 40% of high school seniors do not believe that there is a great risk in trying heroin.
Recent studies suggest a shift from injecting to snorting or smoking heroin because of increased purity and the misconception that these forms of use will not lead to addiction.
Heroin is processed from morphine, a naturally occurring substance extracted from the seed-pod of the Asian poppy plant. Heroin usually appears as a white or brown powder. Street names associated with heroin include "smack," "H," "skag," and "junk." Other names may refer to types of heroin produced in a specific geographical area, such as "Mexican black tar."
The short-term effects of heroin abuse appear soon after a single dose and disappear in a few hours. After an injection of heroin, the user reports feeling a surge of euphoria ("rush") accompanied by a warm flushing of the skin, a dry mouth, and heavy extremities. Following this initial euphoria, the user goes "on the nod," an alternately wakeful and drowsy state. Mental functioning becomes clouded due to the depression of the central nervous system.
Reports from the Drug Abuse Warning Networks (DAWN) Annual Medical Examiner Data from 1997 show that heroin/morphine was the top-ranking drug among drug-related deaths in 14 US major metro areas. It ranked second in another eight.
According to DAWNs Year End 1998 Emergency Department Data, 14 percent of all emergency department drug-related episodes had mentions of heroin/morphine in 1998. From 1991-1996, the number of heroin/morphine mentions more than doubled.
Health Hazards
Irreversible effects. Heroin abuse is associated with serious health conditions, including fatal overdose, spontaneous abortion, collapsed veins, and infectious diseases, including HIV/AIDS and hepatitis.
Long-term effects. Long-term effects of heroin include collapsed veins, infection of the heart lining and valves, abscesses, cellulitis, and liver disease. Pulmonary complications, including various types of pneumonia, may result from the poor health condition of the abuser, as well as from heroin's depressing effects on respiration.
Infection. In addition to the effects of the drug itself, street heroin may have additives that do not readily dissolve and result in clogging the blood vessels that lead to the lungs, liver, kidneys, or brain. This can cause infection or even death of small patches of cells in vital organs.
