OK, I've made some initial assessments based upon my observation of others and I think the following has a tendency for each type:
ENTP/INTP/INFP/ISFP: marijuana
INFJ/ENFJ/ESFJ: cocaine, speed
INTJ/ENTJ/ISTJ/ESTJ: alcohol
ENFP: anti-anxiety meds coupled with ecstasy
ISFJ I've noticed is the only type that doesn't seem to have a predisposition towards any addictions- they like healthy living, exercise etc.
