Drug addiction is a severe pattern of substance use in which seeking or using a drug becomes difficult to control even when it is harming health, relationships, work, finances or safety. Clinicians usually diagnose a specific substance use disorder rather than using “drug addiction” as a single diagnosis. Examples include opioid use disorder, stimulant use disorder, cannabis use disorder and sedative use disorder. For college students, drug addiction can intersect with classes, work, housing, money, relationships, transportation, privacy, and the sudden expectation that you coordinate your own care. The condition itself is only one part of the problem; the system around it can either reduce or multiply the load.
