Drug Addiction: A Definition

Addiction is defined as a compulsive physiological and psychological need for a habit-forming substance despite clear negative impact resulting from use. Continuing use of an addictive substance induces adaptive brain changes that lead to tolerance, physical dependence, and uncontrollable cravings. At this stage of addiction, the dependence is so strong that stopping is extremely difficult, and causes severe physical and mental withdrawal symptoms.

Regardless of professional status, the consequences of drug addiction can be devastating. Research shows that, in 2003, drug overdose was the second-leading cause of accidental death in the United States, accounting for over 11,000 deaths.

Once an addiction takes hold, the addicted person will go to extreme lengths to maintain the habit. At this point, he or she loses consideration for others and for the consequences of the addiction in their own personal and professional lives.

In addition to the intense craving to feed the addiction, the addicted person is equally driven by the fear of discovery. This fear is far greater for women than men. Society is more disapproving of an addicted woman than an addicted man. Over and above the common fears of personal and family ridicule and fear of losing the affection of loved ones, women face the fear of separation from their children.

Addiction is a complex disease that is treatable. It is not a moral failing. In order for people to break free from drug dependency, they must deal with their own unique physical, psychological, and emotional issues.
