The diagnosis of substance dependence is closest to what people often refer to as drug addiction. 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 who is highly tolerant to a substance may have a very high blood level of the substance without being aware of any effects of the substance. For example, people who are extremely tolerant to alcohol may have blood-alcohol levels far above those used in the legal explanation of intoxication but show some signs of alcohol intoxication. The risk of tolerance varies greatly from one substance to the next. Cannabis and PCP shows lower risks for tolerance while alcohol, opioids, stimulants, and nicotine have high risks for tolerance.
When using the substance suddenly stops, people who are physiologically dependent on substances often show severe withdrawal symptoms. The symptoms may be so severe that the substances must be withdrawn gradually in order to prevent the symptoms from becoming overwhelming or dangerous.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 . As an instance, 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.
Most people who are dependent on a substance crave the substance and will do almost anything to get the substance (e.g., steal, lie, prostitute themselves) when the craving is strong. Their entire lives may revolve around obtaining and ingesting the substance. The cycle of going back to the substance again and again will always happen despite having the attempt on cutting back or quitting the use of the substance.
