ANS: A
Drug misuse, abuse, and addiction are considered voluntary behaviors. Cultural norms define what is abuse and misuse. Addiction is a psychologic dependence on a substance with or without physical dependence. Physical dependence is an involuntary response to the pharmacologic characteristics of the drug such as an opiate or alcohol. Legality is not always a factor in substance abuse. Legal substances such as alcohol and tobacco can also be misused or abused and can cause addiction.
