Heroin, derived from opium, is one of the most addictive and destructive of drugs. Its use gives one a 'high,' a carefree self-confidence, a feeling of well-being. But as use continues, more and more is needed to reach that point. True physical addiction sets in.
The heroin addict is often undernourished because he does not feel hungry. He may pay so much for his drug that he cannot afford decent food. Indeed, he usually has to steal to support his expensive habit. In his undernourished state he is likely to contract infection. Also, using unsterilised injection techniques, he may get hepatitis, fatal blood poisoning, and abscesses of the liver, brain and lungs. One addict admitted: "Our life is such that jail is a place to get healthy."
Heroin users live under the constant threat of death from an overdose or from regular use. In fact, New York city reports that heroin addiction now is by far the leading cause of death between the ages of fourteen and thirty-five.
