Summary
DOB is an extremely potent and long-lasting psychedelic amphetamine with a very slow onset (1-3 hours) and duration exceeding 18-30 hours. Due to the delayed onset, users may mistakenly redose, leading to dangerous overdoses. High doses can cause severe vasoconstriction requiring medical intervention; fatal cases have been reported involving ergotism-like complications.
Perspectives
“There was a distinct enhancement of visual perception, and some strengthening of colors. A clean, cold feeling of wind on the skin. I felt an enriched emotional affect, a comfortable and good feeling, and easy sleeping with colorful and important dreams.”

Pattern broadly mirrors other serotonergic psychedelics: acute tolerance develops rapidly, partial tolerance persists about a week, and baseline typically returns within 2β3 weeks, though the long duration of DOB can make perceived tolerance more variable.

Effects
Aggregated from 35 single-substance Erowid and 21 Bluelight experience reports; 24 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 24 DOB reports where another drug was taken too, 4 (16.7%) mention hospital, emergency services or an overdose, 2 (8.3%) a seizure and 3 (12.5%) psychosis. In the 35 single-substance reports: 17.1%, 5.7% and 2.9%. These are not in the figures above: they cannot be put down to DOB alone, and a mention is not always something that happened to the writer.

SPEAKER 1: '... and I was telling him to sell, sell, that the market was going to crash any day now, and of course he wouldn't listen to me. He was going on and on about how money was just a game now, not anything significant, and that he was going to quit his job and start writing music for the vibraphone.
I have always said DOB allows me time to do whatever I didn't have time for on LSD. This is because while an LSD trip may last a good 8 hours or more, a good DOB trip will last around 18-30 hours (This report is going to be long too).
[Erowid Note: A substance(s) in this report might be identified incorrectly. Erowid reviewers question the author's identification of the drug described. Although the report is included in the collection, the substance might be something other than the author believed it to be.] Note: I am writing this partially to try...
Early one weekend afternoon I decided to try something new. I had recently been gifted with a sample of a quite rare substance known as DOB. From what I had read and been told it was similar to 2CB both chemically and in action, but fantastically long lasting.
About nine months ago, I had my first experience with hard drugs. I was sixteen, and at this point had never tried anything other than weed. Me and a group of friends were supposed to meet up for Toronto's 'Nuit Blanche'. What this is is basically a downtown-wide lightshow.
The following report is from my first and only experience with DOB. I would honestly try it again, but with much greater caution. The week prior to the experience, a buddy asked if I wouldnΒt mind picking his friend up and dropping him off somewhere near where we lived.
[Erowid Note: Driving while intoxicated, tripping, or extremely sleep deprived is dangerous and irresponsible because it endangers other people. Don't do it! ] We get to the pool and find a plethora of people, this makes both Jason and me uncomfortable, so we head across the street to a different pool. Same situation.

This was my second experience with DOB, and the first that I'm writing about. It's been just a bit over a year and a half since my last trip report, and the reason for this requires some explanation before going on.
It was a seemingly normal Friday afternoon. I got home from work around 5:30pm and I felt a familiar feeling. I get a certain difficult to describe feeling when I know it's my time to trip. It's a good feeling that's sort of like a combination of excitement, happiness and nervousness.
disclaimer: very long report Background information: - sex: male - age: 28 - weight: 73 kg - setting: nervous, apprehensive but excited - set: at home alone, later with my current girl acquaintance - medication: 20 mg telmisartan, not medically necessary but taken for improved vascular health and other benefits.
This has been a month ago but since itβs been ages since anyone wrote a DOB report (except Kaleida last year) and the fact that it was such a great experience I thought Iβd write a report. I started one the day after my trip but I canβt find it anywhere anymoreβ¦ 10:00pm ( T+0:00 ) β I dose a 1.4mg blotter.
EDIT: *** GC/MS reports conclude this substance to be DOB*** http://www.unc.edu/~oseli/blottertest.pdf This was from this fall, I thought I'd share with bluelight. First, a little background. I picked up some hits a while back and after they were gone I found 4 hits underneath my desk and set them aside.
DOB - First time - Impressed! 2.75mg (2.0mg + 0.75 an hour later). The day starts out sorta like this: I'm walking outside to grab something from my car, when, i see a flying balloon in the sky. It looks like one of those helium balloons, running outta gas, on its way down, with a little tiny package with a note.

2 tabs each containing 1.5 mg DOB taken orally. Attempt to take them sublingually is foiled by their awful nauseating flavor. Body load can definitely be felt. I feel "high" but in a stimulant sense. Itβs an energetic feeling, like there is electricityβ¦
