PY - 2009 T2 - Pharmacology for the Physical Therapist AB - As generally understood, drug abuse includes any illicit use of a drug for nonmedical purposes, usually for altering consciousness, but also for body building. The term also denotes the deliberate use of chemicals that are generally not considered drugs by the lay public, but may be harmful to the user. Often, the motivation for drug abuse appears to be the anticipated feeling of pleasure derived from the central nervous system (CNS) effects of the drug. If physiologic dependence is present, preventing a withdrawal or abstinence syndrome reinforces continued drug abuse.
