  • [DOB]


DEA CODE 7391: Schedule 1

DOB is a psychedelic substance of the amphetamine class that produces unusually long-lived psychedelic effects. While DOB had first been synthesized in 1967 and briefly tested in 1971, it took until the 1991 publication of the book PiHKAL ("Phenethylamines I Have Known And Loved") by Alexander Shulgin to be documented in-depth.

Today, DOB is used as a recreational drug and an entheogen more commonly found in the streets the form of misrepresented LSD due to its ability to fit onto similar-sized blotter paper.

Along with its sensitive dose-response, unusually long and unpredictable duration, many reports also suggest that this substance may be overly difficult to use safely for those who are not already very experienced with using hallucinogens. https://psychonautwiki.org/wiki/Experience:2_tabs_DOB_-_My_DOB_Nightmare.

DOB is not habit-forming, and the desire to use it can decrease with use. It is most often self-regulating.

DOB is a psychedelic known for its potent nature and long-lasting effects. It is pretty uncommon, though some use has been reported since the 1970s. It's a clearly stimulating drug, distinguishing it from a psychedelic like psilocin. The substance is part of the DOx class of substituted amphetamines. Onset: 1-2 hours for some effects, 3-4 hours for full effects. Although the psychedelic effects generally subside within ~24 hours, stimulation and insomnia sometimes persist up to 36 hours, which is influenced by the dose. Because the drug can take hours to become clearly active, impulsive redosing is a concern. Don't redose even if it doesn't appear to be working in the first couple hours!


DOB is a relatively uncommon synthetic psychedelic. It is best known for its very low doses and long duration. Historically it has rarely been taken deliberately, but in place of LSD, however it has recently found its own place in the research chemical scene.
