What is narcotic drug withdrawal?
Narcotic drug addiction is physical and mental dependence on certain kinds of drugs. Narcotics change your response to sensations. Narcotics also produce mood changes, unconsciousness, or deep sleep. Examples of narcotics are heroin, codeine, morphine, and methadone. If you are addicted to a drug, you may have to stop taking it because of short supply, lack of money, or being in jail, a hospital, or another institution, in which the drug is not available. You may also stop taking the drug because you want to break your drug habit.
