PY - 2019 T2 - Katzung & Trevor's Pharmacology: Examination & Board Review, 12e AB - Drug abuse is usually taken to mean the use of an illicit drug or the excessive or nonmedical use of a licit drug. It also denotes the deliberate use of chemicals that generally are not considered drugs by the lay public, eg, solvents, but may be harmful to the user. A primary motivation for drug abuse appears to be the anticipated feeling of pleasure derived from the CNS effects of the drug. The older term “physical (physiologic) dependence” is now generally denoted as dependence, whereas “psychological dependence” is more simply called addiction.
