How long does it last, for, say, 1mg put on my gum? Would this stuff work for a club party with a lot of dancing?
Are you talking about 1mg on blotters? If so thats a decently strong dose as long as you hold the tabs and your saliva in for atleast 20 minutes, but not at all worrying in a club enviorment if you've been out tripping before. I think with this the only thing that would make you feel uncomfortable in public is the physical intensity. It's very easy to keep it together mentaly.
You'll start feeling it while your still holding it in your mouth probably. Peak is somewhere around +1:30 and +2:00 I think. Drops off around +5:00
