I will say that the audio effects are so profound (for me) that I would probably be more hard pressed to act or behave normally than I would on almost any other psychedelic (besides something like DMT, or ibogaine, where it's impossible to even understand what's happening outside of the drug). Not everyone seems to get as profound an alteration of sound, but for me, human voices sounded like robot frogs, and it was like I was deaf, but could hear overtones, or something.
I got a distinct movement and pressure in my inner ear... it felt like part of my inner ear actually moved, I distinctly felt it move as the sounds began to really start to shift. It was weird and very physical. I was rather disturbed by how long the hearing changes lasted, too... like 3 times as long as the mental effects, or more. 24 hours later and there were still hints of it, the first time, I started to get worried that something was damaged or wouldn't return to normal.
I found the headspace fairly euphoric and certainly psychedelic, but most of the wildness of the mental state came from how insanely altered the world appeared simply due to my hearing, while my visual field was utterly unchanged. It tripped me out, like I wasn't real or something. Hard to explain. If all the same effects were there but my hearing had been unchanged, it would have been a run of the mill, rather weak and functional trip, but the audio effects took it to a truly unique and weird place. I found it highly enjoyable, but possibly largely because of the novelty. I have taken it 2 other times, once again at the same dose (50mg) but during a period of strong perma-tolerance, and it was much weaker both in mental and audio effects, and another time without tolerance, many years later, at 30mg, and I only experienced some pitch lowering, and it felt threshold.
Speaking of that, 7mg of 5-meO-MiPT last eve was very pleasant after not having it for many years.
Love that stuff
