PY - 2022 T2 - Current Medical Diagnosis & Treatment 2022 AB - The term “dependency” was previously used to describe a severe form of substance abuse and drug addiction characterized by the triad of: (1) a psychological dependence or craving and the behavior involved in procurement of the drug; (2) physiologic dependence, with withdrawal symptoms on discontinuance of the drug; and (3) tolerance, ie, the need to increase the dose to obtain the desired effects. The terms “dependency” and “abuse” were dropped in DSM-5 in favor of the single term “substance use disorder,” ranging from mild to severe. Many patients could have a severe and life-threatening abuse problem without ever being dependent on a drug. Substance use disorder is a treatable, chronic medical illness. Clinicians and health care systems must work against bias toward people with substance use disorder. Medication-assisted treatment is available for a number of substance use disorders and is a key element in their management.
