Drug Use Disorder

Drug use disorder refers to the presence of any of a collection of drug-specific diagnoses that are characterized by cognitive, behavioral, and physiological symptoms accompanying repeated use of a drug despite significant substance-related problems causing harm to the user or to others. Common drugs of abuse in contemporary American society include cannabinoids, opioids, amphetamines, cocaine, and many other drugs. The popularity of specific drugs has varied over time in relation to drug availability and cost. The most recent trend has been an influx of “designer drugs,” substances developed synthetically by manipulating the molecular structure to avoid classification as illicit drugs (hence circumventing prosecution) while retaining the psychoactive properties of illicit drugs.
