What people often referred to as drug addiction is synonymous to the diagnosis of substance dependence. a person is physiologically dependent on a substance when he or she shows either tolerance or withdrawal from the substance. Tolerance is present when a person experiences less and less effect from the same dose of substance and needs greater and greater doses of a substance in order to achieve intoxication. People who have smoked cigarettes for years often smoke more than 20 cigarettes a day, when the same amount would have made them violently ill when they first began smoking. A person may not have enough awareness on the effects of the substance but can have high tolerance on it and may have a very high blood level of the substance . For example, people who are greatly tolerant to alcohol may have blood-alcohol levels far above those used in the legal definition of intoxication but illustrate some signs of alcohol intoxication. From one substance to the next, the risk of tolerance varies. Cannabis and PCP show lower risks for tolerance while alcohol, opioids, stimulants, and nicotine have high risks for tolerance.
When the substance use suddenly stops, people who are physiologically dependent on substances often show severe withdrawal symptoms. Symptoms may be so severe that in order to prevent the symptoms from becoming overwhelming or dangerous, the substances must be withdrawn gradually . These people may take the substances to relieve or avoid withdrawal symptoms. For example, a person dependent on alcohol may have a drink first thing in the morning to relieve the withdrawal symptoms.
Physiological dependence (i.e., evidence of tolerance or withdrawal) is not required for a diagnosis of substance dependence, however. The diagnosis can be given when a person compulsively uses a substance, despite experiencing significant social, occupational, psychological, or medical problems as a result of the use.
When the craving of the substance is so strong, once a substance dependence person starts craving for the substance, they will do almost anything like stealing, lying, and prostituting themselves. Obtaining and ingesting the substance may be the center of the lives of these people. They may have attempted repeatedly to cut back on or quit using the substance, only to find themselves compulsively taking the substance again.
