About Substance Abuse

Substance abuse: refers to the harmful or hazardous use of psychoactive substances, including alcohol and illicit drugs.

Substance dependence or addiction: more serious than abuse, this maladaptive pattern of substance use includes such features as increased tolerance for the substance, resulting in the need for ever-greater amounts of the substance to achieve the intended effect; an obsession with securing the substance and with its use; or persistence in using the substance in the face of serious physical or mental health problems. (DSM-IV-TR 4th edition, Text Revision; APA 2000).
