I dont think the mbti type system is applicable to drug abuse. I only have experience with marijuana myself and in my circle of friends. The few SJs, who did it, did it in school. They had huge issues with some of our teachers and I am sure school time was a pain in the ass for many. Somehow they managed to survive by having extensive parties consuming alcohol + marijuana. (I of course participated in

)
When school was over though and they figured now their course of their life lies in their own hands, they changed and eventually banished all marijuana-related things. Their alcohol abuse though peaked and I have to watch myself, cause I am going down that road too.
I myself started to smoke after school. Somewhat lost not knowing where to go, having no clue about life, I dedicated my mind to the metaphysical state of things and became nearly nuts. I highly react to marijuana, need one stroke and I have lost track of reality. I get paranoid.
Given the mbti dichotomies, I would say the function mix in a way then that Ne + Fe take the lead. Given Fe to be a weak function it functions haphazard at best. And Ti is just to justify ones view on things to oneself. Which ultimatively can be described as being nuts.
I developed my own personal typology system, when being on pot and I didnt know about mbti back in those days, so I was pretty much alone with my thoughts and discoveries. Sometimes I was ahead of my time for sure, but sometimes I was nuts I am sure too.
I eventually stumbled over Jung and that was a relieve, ended up with mbti / socionics then and quit smoking when I joined university. Wouldnt start it again, the experience has left my mind fragile and receptive to madness and I need to watch myself to not loose it. Maybe in time the mind will heal and grow more strong again, for the moment though a joint could make me loose the last 4 years completly again.
The only type I know about who havent quit smoking, seem to be types that need a certain feeling to feel good. There is that INFJ, who regulary needs to retreat in his fantasy world. He talked about quitting a lot of times but he just is not strong enough. He is seeing a counsellor now and I am hoping something good will come out of it, cause the doctor seems to be the only guy he listens too.
Another one is an ESTP, who gets a social butterfly when being stoned. Therefore he is always stoned. He knows like 1 billion people, has become a building sales manager and is quite the man. Though only when he is stoned, without he starts to doubt himself bigtime and becomes really insecure.
Another is INFP, who has a strict agenda about when and when not to take drugs. I think he smokes like one weekend every month, also as a meaning of retreat. That guy is pretty stable, though its hard to understand him for me sometimes.
All three though show grave symptoms of long-term memory losses, they have an incredible problem to focus on learning things for university or concentrate in general. And all three are subjective to grave mood swings, which can come to an outstanding person, suddenly and unpredictable.
Therefore I am keeping contact highly superficial.
One thing is for sure though, its not easy to see your friends wither to their ends..
