What is the definition of substance use disorder?

The definition of substance use disorder is accurately captured as a medical condition characterized by an individual's inability to control their use of a substance despite experiencing negative consequences. This recognizes that substance use disorders involve a compulsive pattern of consumption that often leads to significant impairment or distress.

The emphasis on the inability to control use highlights the chronic nature of the disorder, which can persist even when the individual is aware of the adverse effects their substance use has on their life, relationships, and health. The medical perspective framing substance use disorder as a condition rather than just a behavioral issue supports the understanding that it often requires comprehensive treatment, including medical and therapeutic interventions.

Substance use disorder is not simply a temporary condition triggered by stress, as it often has underlying biological, psychological, and social factors contributing to its persistence. Additionally, it is generally not accurate to categorize it solely as a behavioral issue that can resolve without treatment; many individuals require help to overcome these challenges. Furthermore, while individuals with substance use disorders may experience difficulties in social situations, this is just one aspect of a broader condition characterized by complex patterns of misuse and dependency on substances.
