    Summary TheDrug.Wiki Erowid TripSit PsychonautWiki

    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.”

    Reset 7–14 days for baseline

    Tolerance Decay

    Full tolerance 3d Half tolerance 7d Baseline ~14d

    Pattern broadly mirrors other serotonergic psychedelics: acute tolerance develops rapidly, partial tolerance persists about a week, and baseline typically returns within 2–3 weeks, though the long duration of DOB can make perceived tolerance more variable.

    Time for Everything I Couldn't Do on LSD neutral exp #97945

    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).

    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.

    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.

    This has been a month ago but since it’s been ages since anyone wrote a DOB report (except Kaleida last year) and the fact that it was such a great experience I thought I’d write a report. I started one the day after my trip but I can’t find it anywhere anymore… 10:00pm ( T+0:00 ) – I dose a 1.4mg blotter.

    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.
