It's quite unique, so far I've only insufflated 25E-NBOH crystals I cut with caffeine, and vaporized it, whereas all other 25X-NBXX's I've used (25C-NBOMe, 25I-NBOMe and 25B-NBOH) have been administered via a sublingual route of administration. Insufflated 25E-NBOH was a unique experience from vaporizing it, I'll try to do a rundown on each.
Insufflated 25E-NBOH induced an experience that reminded me heavily of 25C-NBOMe and 25I-NBOMe, the sort of hyperstimulating psychedelia that reminded me of coadministering LSD and methamphetamine. It took a half hour or so to come up, and over that period I began to experience light bruxism and my leg was jumping as if it was at a music festival, but the rest of my body was no more stimulated than having drank a cup or two of coffee. By the 45-60 minute mark, the psychedelia is obviously coming on, and it'll evolve for another 5-6 hours before tapering off quickly, leaving only a half hour or so of residual stimulation. The psychedelic elements of insufflating 25E-NBOH are super unique, the visuals look like nothing else I've ever touched, almost resembling neon graffiti that casts itself upon the textures of what you can see, at some points levitating clean off, rotating to be visible to you, and communicating messages relevant to whatever you're thinking about. Sometimes it looked more like formal Arabic writing, as you'd see written on a flag or in an ancient mural. There was a stunning amount of texture distortion going on, reminding me of 2C-B over 35mg or LSD over 750ug (10 average tabs off the street), the woodgrain was flowing like river rapids, and the screen of my phone was holographically levitating above the material object that is the phone, with an odd shimmer to it that looked like a silver powderized metal being levitated by an acoustic speaker almost, with each granule moving at its own rather speedy pace. The consistent theme of this drug via either RoA is that it is intensely psychedeilc, and everything moves fast as fuck. The headspace with intranasal administration was more profound than when it's vaporized, but vaporized 25E-NBOH still has a solid amount.
Vaporized 25E-NBOH was much more of an entactogenic experience, giving me "molly skin" almost immediately, tempting me to roll around on the carpet shirtless or pick up an ice cube just to feel how shockingly cold ice has suddenly become. The visuals are much more of a neon hypersaturation on everything I can see, but for some reason especially green and dark blues. Cyan looks almost muted through vaporized 25E-NBOH, and I'm not quite sure why. This RoA is somehow even more stimulating than insufflation, but I've mixed it with methamphetamine, caffeine and bupropion all in tandem a handful of times and it's not been overwhelming in any way. 25E-NBOH is also less visually intense when vaporized, I won't see symbols peeling off the walls to float right in front of me or anything like that, but I will certainly experience a slowed-down version of the texture distortions, tracers are significantly more intense with vaporization, and I can modulate my visuals by changing how much my other senses are experiencing, in a way that reminds me heavily of LSD. Overall, this drug is very acidlike, though still distinctly a 25X-NBXX in nature. The sensory-visual relationship is such that when outside on a humid night, versus inside in a chilly room, or wearing a bathrobe versus work clothing, etc. can all noticeably and immediately shift the nature of the visual experience in ways that few other psychedelics will do, most others will maintain a consistent visual character relative to the intensity of the experience at any given time, whereas LSD, 25E-NBOH, allylescaline, miprocin and N,N-DiPT will all vary extremely heavily by set and setting, all with an immediacy unparalleled, perhaps taking 10-15 seconds at the longest to catch up to changes in set and/or setting.
Hope that's a useful rundown, if you have any other questions lmk.
