Summary
A relatively new and popular research chemical with psychedelic properties. Users report an uncomfortable body load with very strong visuals, though with less of a mental aspect than most psychedelics. Commonly missold as LSD, since it is much cheaper to produce. The drug is reported to be unsafe by many, and has caused several deaths at 'regular' doses.

Effects
Aggregated from 122 single-substance Erowid and 62 Bluelight experience reports (the Bluelight figures come from the 50 of them read for effects); 104 Erowid reports where another drug was taken too are left out
Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

Also reported in combinations. In the 104 25I-NBOMe reports where another drug was taken too, 19 (18.3%) mention hospital, emergency services or an overdose, 6 (5.8%) a seizure and 5 (4.8%) psychosis. In the 122 single-substance reports: 22.1%, 7.4% and 8.2%. These are not in the figures above: they cannot be put down to 25I-NBOMe alone, and a mention is not always something that happened to the writer.

Set: I've been feeling really bound up psychologically, very self-constrained, and I thought a psychedelic experience would do me good - a little WD-40 for the soul. Setting: My flat during the autumn. Previous experience: a just-over-threshold dose of LSD many, many years ago (Yup, that's it - not even weed).
IΒve tripped on 25I before. Sure, it was sold as mescaline the first time and I didnΒt know better, but IΒve done it before. Loved it. Was a small dose I think, didnΒt know then, guessing now that it was probably 500 Β 700 Β΅g. My first trip was with my friend D.
This is a story of my psychedelic year 2012 and how it ended horrificly. I've been going through what exactly happened that day and processing the events that led to it. It has been my intention for a while to write an experience report about it, but it was not until today that I decided that I'm ready.
The day that would change my life forever began with a text from our school, stating that classes will be cancelled for the day due to inclimate weather. A fresh sheet of ice and snow covered nearly every road in town, promising a wreck to almost anyone who went out.
FROM THE TRIP SITTER: T-00:00 My friend R took the single tab and placed it under his tongue for 10 minutes, commenting on the bitter taste. T-00:03 R then goes on to explain the numbness on his tongue.

I feel that this trip report needs a short introduction, so bear with me guys. 25i-NBOMe is one of those drugs that I'm not sure about. On the one hand its one of the strongest psychedelics I've ever tried, but on the other I feel like there is an element missing to its high, something I can't put my thumb on, one of m...
25i-NBOMe sublingually, 3.75mg - Inexperienced Hello there, I'm here to report on my experience a couple nights ago with this novel compound, 25i-NBOMe, or 2c-i-NBOME, I see it written so many different ways.
Here is a short story I wrote about an 18 year old lad, Experimenting with the research chemical, 25i-NBOMe. December 21st 2012. The βLast day on earthβ My first ever trip report on my most visual trip to date. Herein is my second?* experience with 25i-NBOMe.
It has almost been a year since the time of year I took 25i for the first time. This memory is very vivid, i just wanted to finally tell someone about it. So March of 2014 I was a senior in highschool nearing the end of it.
I told bits and pieces of this story to my partner the other day. I showed him the goosebumps on my arms and my shirt drenched in sweat as I concluded parts of the story. It's more or less humorous and light harted. It takes place a number of years ago, springtime.
Dosage: 6 gummies or 12 drops of liquid 25i Route: orally Duration: 6 hours Medical Conditions: none My friend George was a 15 year old male (but is now 18 so itβs okay) from Vermont. George had a lot of experience with weed and other drugs but had taken no psychedelics before this day.
Let me first start off by thanking everyone who took time out of their day to read this post. I would also like to state that prior to taking 25I I have never had any experience with psychedelics and this would be my first post ever on blue light but I've been a frequent lurker.

My perception of time and the order of events is really off but I would say I started to feel effects in 10-20 minutes after taking it, it numbed my tongue and tasted of harsh chemicals, the first things I noticed were, a bright pink field in the air, almostβ¦
