"With society's growing use of drugs and substances of abuse, health care professionals need to be aware of how the drugs patients use affect behavior, cognition, learning, memory, and other aspects of mental and physical health. Physicians, other prescribers, and pharmacists need to know the abuse potential and current "street use" patterns of prescribed drugs, and all health professionals need to recognize signs and symptoms of drug or substance intoxication, overdosage, and withdrawal."--BOOK JACKET.
