Drug addiction is marked by physical dependence, and is defined by the uncontrollable, compulsive urge to use a drug despite harmful consequences. Psychological responses to drug use may reflect anxiety, protective, and/or positive pleasure motivations. Physiologically, drug use affects the following areas of the brain: the brain stem, the cerebral cortex, and the limbic system.
