The diagnosis of substance dependence is closest to what people often refer to as drug addiction. When a person shows either tolerance or withdrawal from the substance, the person shows physiological dependence on the substance. 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, this shows tolerance. 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 very tolerant to alcohol may have blood-alcohol levels far beyond those used in the legal meaning of intoxication but show little signs of alcohol intoxication. The risk of tolerance varies greatly from one substance to the next. Alcohol, opioids, stimulants, and nicotine have high risks for tolerance whereas cannabis and PCP appear to have lower risks for tolerance.
People who are physiologically dependent on substances often show severe withdrawal symptoms when they stop using the substances. The symptoms may be so severe that the substances must be withdrawn gradually in order to prevent the symptoms from becoming overwhelming or dangerous. In order to relieve or avoid these withdrawal symptoms, these people may take the substances . 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. Despite the experience of significant social, occupational, psychological, or medical problems as a result of the use , the diagnosis may be given when a person compulsively uses a substance .
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.
