A little tidbit of data to add to the pile:
I gave a bunch of 1mg blotters (isomer unknown), that I'd somehow picked up along the way, to a close friend for Burning Man this year, and everyone gave it a stellar report, except for one guy who had a crisis, but from what I was told he would've had one on any psychedelic and should not have been given it to take in the first place.
They reported notable visuals, but only in the dark. Any light dispelled the visuals immediately, and also brought with it a sort of "sober-ish" vibe. Sleep was fine but the effects were still noticeable after.
Keep in mind that these people had already spent days taking MDMA/MDA/2C-'s etc., who knows how that may have skewed the results.
I sort of wish I'd held onto some of those blotters now, I do have a couple mg in alcohol in the freezer but I don't know whether or not it's the same isomer. One neat thing is that one of the partakers was an underground psychedelic therapist who'd sort of been hoping to try bromo-dragonfly for a couple years, and he loved the experience.
