High Quality Content by WIKIPEDIA articles! DOB, also known as Brolamfetamine and Bromo-DMA, is a psychedelic hallucinogenic drug and a substituted amphetamine of the phenethylamine class of compounds, which can be used as an entheogen. DOB was first synthesized by Alexander Shulgin in 1967. In his book PiHKAL (Phenethylamines i Have Known And Loved), Shulgin lists the dosage range as 1 to 3 mg for the racemate. The enantiopure compound dosage is at least half of that. DOB is generally taken orally. According to Shulgin, the effects of DOB typically last 18 to 30 hours. Onset of the drug is also long, sometimes taking up to three hours. The substance has been described as a more lucid, more amphetamine-like version of LSD, albeit far longer lasting.
