-There is no such thing as and 'addictive' personality but instread its the certain personality traits or features that may contribute to an individual seeking out and trying new substances which may lead to addiction.
Eysenck put forward the PEN model of personality
-Psychoticism = irresponsible and need for immediate gratification
-Extraversion = social, talkative and outgoing
-Neuroticism = anxious, restless and frustrated
PEN explained:
-If individuals score highly on neuroticism and extraversion seem to be at greater risk of becoming an addict.
-The key personality feature here is impulsivity. Usually identified with people who lack planning skills, are risk takers, sensation seeker and a chaotic lifestyle.
