In other words, physical dependence in and of itself is of limited utility in determining whether or not someone has a substance use disorder. This is an important factor because we can develop tolerance and experience withdrawal from any number of drugs that we do not abuse. Psychological dependence, or drug craving, is a recent addition to the diagnostic criteria for substance use disorder in DSM-5. In addition to withdrawal, many individuals who are diagnosed with substance use disorders will also develop tolerance to these substances. For example, withdrawal from sedative drugs often produces unpleasant arousal and agitation. These symptoms usually are opposite of the effects of the drug. Tolerance can cause the user to increase the amount of drug used to a dangerous level-even to the point of overdose and death.ĭrug withdrawal includes a variety of negative symptoms experienced when drug use is discontinued. Tolerance is linked to physiological dependence, and it occurs when a person requires more and more drug to achieve effects previously experienced at lower doses. In contrast, a person who has psychological dependence has an emotional, rather than physical, need for the drug and may use the drug to relieve psychological distress. Physical dependence involves changes in normal bodily functions-the user will experience withdrawal from the drug upon cessation of use. In individuals diagnosed with a substance use disorder, there is a compulsive pattern of drug use that is often associated with both physical and psychological dependence. A person who has a substance use disorder often uses more of the substance than they originally intended to and continues to use that substance despite experiencing significant adverse consequences. Drug use disorders are addictive disorders, and the criteria for specific substance (drug) use disorders are described in DSM-5.
