DOB - Substance Search

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.”

— Alexander Shulgin, PiHKAL (with 0.4 mg)

Tolerance

Build-up develops rapidly; very long duration provides natural spacing

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.

Cross-Tolerances

Other serotonergic psychedelics (e.g., LSD, 2C-x, DOx)
