Let's Introducing about Narcotics

Narcotic drugs are opium and pain-killing drugs made from opium, such as heroin, morphine, paregoric, and codeine. Synthetic drugs such as Demerol and Dolophine are classified as narcotics. Cocaine and marijuana are not chemically narcotic but are legally classified as such.
When the abuser of a narcotic is addicted, his body requires repeated and larger doses of the drug. This happens because the body develops a tolerance for the drug and requires more of it to achieve the same "high" as the first shot of the drug gave the abuser. Psychological dependence is addiction where in the drug becomes a habit for emotional reasons.
the first reaction to heroin is a reduction of tension, easing of fears, and relief from worry. feeling "high" may be followed by a period of inactivity bordering on stupor. The drug depresses certain areas of the brain and may reduce hunger, thirst, and the sex drive. The drug may also reduce feelings of pain. the effects of the drug are influenced by the user's personality, the size and frequency of the dose, and how the drug is taken.

Many addicts state that getting a continued supply of their drug is the main object of their lives. Concentration on obtaining it prevents the addict from continuing either his education or his job. his health is often affected, and statistics indicate that his life span may be shortened by fifteen to twenty years. He is often in trouble with his family, society, and the law.
Medical authorities agree that the addict needs treatment for physical addiction and withdrawal sickness. following this treatment, he needs rehabilitation work to prevent a return to addiction. Because the rebuilding of a life requires many services and special programs, the Narcotic Addict Rehabilitation Act of 1966 gives certain addicts a choice of treatment instead of neglect. The law also provides that a complete range of rehabilitation services be made available to narcotic addicts in their own communities.
