I've dealt with authority figures and unknowing peers on several psychedelics, and for me, people had a hard time noticing if I was on anything. I was already slightly off sober, so talking about space, time, and other weird subjects wasn't out of the ordinary for me. My pupils still get buggy without drugs as well, and it has been more than 5-years without psychedelics. So it really depends on how people already perceive you. I guess that isn't a factor with police and so forth, and I didn't get too interested in 2C's, with exception of 2C-E. So I don't know if you can bring yourself out of a trip on 2C-I if you need to do so.
