One study show that college-age extraverts tend to engage in more "pro health" activities (with INTP and INFP being the least sporty/pro-health types), but also more drinking, smoking, etc. All shocking, I know. It would be interesting to see if those correlations held true as people aged, because I suspect there would be changes in patterns over time.
I didn't take the time to look at the studies and methods in detail, so there could easily be flaws in the studies. I wouldn't be surprised if ISFPs were a little over-represented, since I recall they are one of less direct types in dealing with conflicts, and more likely to use distraction/numbing to avoid dealing with problems (which sounds a e9 to me)... which isn't to say we INFPs don't have our issues, too. Also, I believe the above study drew mostly from patients in treatment, which might also be correlated with willingness to seek treatment and/or inability to hide the substance use.
Addendum: I don't like it much, personally. Makes me feel like my mind is slow, which makes me feel e5 defenseless.
Yeah, extroverts certainly tend to use drugs and alcohol during college.
And I would say FP, IP, and SP would all tend to smoke pot (NPs tho, too; and even many NJs).
I don't think SFs would be much overrepresented, tho, except for the fact that SFPs are probably so highly overrepresented that they outweigh the SFJs, who are probably underrepresented.
