What does the presence of tolerance in Sedative, Hypnotic, or Anxiolytic Use Disorder signify?

The presence of tolerance in Sedative, Hypnotic, or Anxiolytic Use Disorder signifies a decreased effectiveness of the substance. Tolerance refers to the phenomenon where an individual requires an increased dose of a substance to achieve the same effect that was previously obtained with a lower dose. In the context of sedatives, hypnotics, or anxiolytics, this means that over time, the person must consume greater quantities of these substances to experience the initial level of sedation, anxiety relief, or sleep induction.

This occurrence is particularly significant in understanding the progression of substance use disorders, as it indicates a physiological adaptation of the body to the substance, which can lead to increased dosage and potential escalation of use. Tolerance can also contribute to the risk of dependency, as individuals may consume more of the drug to attain desired effects, further reinforcing the cycle of substance use disorder.

Overall, recognizing the role of tolerance is crucial in the assessment and treatment of individuals with Sedative, Hypnotic, or Anxiolytic Use Disorder.
