Nothing happens. *shrugs* I just become a drunk INFJ. Maybe slightly more social and sexually aroused, but really I'm the same.
Since that was a boring answer, like most of these might be

I'll also note how my functions demonstrate themselves in other mental states:
Weed: NiNiNiTiNiNiTiTiNiNiTiNiTiNiTiNiNiNi... "
Hey are you okay?"
*Moves eyes toward the voice* "
Are you going to answer... what pizza do you want?"
*Stares* "I want pizza."
DXM: All extraverted functions die, except a sliver of retarded Se, just enough to navigate the clouds of fog which inhibit my senses. I observe everything detached from own body and surroundings, my thoughts rapidly switching between anxiety provoking "What if..." statements and... even further anxiety provoking "Yep this is happening" statements. Honestly the only two options when I'm on this drug are: Remain in a state of constantly doing (Se) so that you don't have Ni yourself into a hole of darkness, or... don't and suffer. This is why I actually felt more sane riding go karts at my cousin's birthday party on dxm than I did when I was merely sitting down doing nothing.
Opiates and/or Kratom: Unlike the other two, this one actually improves almost all of my functions at least slightly. My Si is quite pleased and thanks me, My Se is less inhibited by my inner sense of caution, My Ne becomes more active, always finding something interesting to think about or discover or write about, and my Fe out of all of my 8 functions suddenly feels easier and more natural to use, as my words become more coherent and expressive and I definitely feel more inclined to be social. Opiates pretty much cure everything wrong with me.
