PSY 240 Chapter Notes - Chapter 11: Binge Drinking, Sleep Disorder, Alcohol Dehydrogenase
Document Summary
Perspectives on substance-related disorders: big bold blue: more than 8% of the general population is believed to use illegal drugs, polysubstance use: using multiple substances. The occasional ingestion of illegal drugs is as well. Intoxication: intoxication: our physiological reaction to ingested substances is referred to as substance, for many substances intoxication is experiences as impaired judgment, mood changes, and lowered motor ability. Substance abuse: defining substance abuse by how much of a substance is ingested is problematic. So we define it in terms of how significantly it interferes with the user"s life. The repeated use of a drug, a desperate need to ingest more of the substance, and the likelihood that use will resume after a period of abstinence are behaviors that define the extent of drug dependence. Depressants: primarily decrease central nervous system activity. Reduce our levels of physiological arousal and help us relax: behavioral sedation and can induce relaxation.
