While it is true that addictions affect the personality of the person who is addicted, this is NOT a personality disorder. Personality disorders are (in theory, anyway) lifetime patterns of specific sets of personality traits that tend to be fairly enduring. Narcisstic, Borderline, Antisocial, etc. Now whether or not all the personality disorders are really disorders of personality is up for debate as well. But my point is that personality disorders are not just when your personality is affected by some external factor (such as alchohol and drug use)
