Document Summary

Tolerance is one property of substances that can propel a person from a simple use to a substance disorder: biology, psychology, and culture influence the development of a substance disorder. Substance intoxication is when the substance use is extreme: categorized in current dsm as a substance-induced disorder. Intoxication is reversible, substance specific, results in maladaptive behaviour or psychological changes associated with the central nervous system, and emerges during/shortly after use. Substance use and problematic use can be hard to distinguish: cultural norms reflect this, e. g. , legal blood alcohol limit across a number of countries show varying tolerances of alcohol behind the wheel, dsm-iv categorizes substance use disorders as: Substance abuse leads to disruption in function. Substance dependence focuses on behavioural patterns/pharmacological effect of substance. Including tolerance and withdrawal: dsm-5 categorizes substance abuse and substance dependence as one disorder: substance use disorder, 2 or more symptoms must be present to meet criteria (rather than just 1 for each in dsm-iv)
