How common is addiction in INTPs?
I consider myself an addict so I'm curious. I've always been "the smart guy" (something that I only believed when I qualified for Mensa) and my parents constantly tell me I'm wasting my potential by consuming various drugs since I was 13, it's sad for me but I'm much better now and and I recently graduated as a computer systems engineer scoring 98/100 in a 202 pages thesis.
Anyways, is my personality influencing my drug use or is it not really that related?
edit: grammar (english is my 3th language)
