					Psychedelic drug
Pharmaceutical compound
4-HO-DBT , also known as 4-hydroxy-N ,N -dibutyltryptamine , is a psychedelic drug  of the tryptamine  family related to psilocin  (4-HO-DMT).[ 1]   It is taken orally .[ 1]  
 
4-HO-DBT was first made by the chemist Alexander Shulgin  and reported in his book TiHKAL .[ 1]   Shulgin reported a dosage of 20  mg orally  to be without effects.[ 1]   However, this compound has subsequently been sold as a "research chemical " and anecdotal reports  suggest that at higher doses 4-HO-DBT is indeed an active hallucinogen , although somewhat weaker than other similar tryptamine derivatives.[citation needed  ] 
4-HO-DBT is found either as its crystalline  hydrochloride  salt  or as an oily or crystalline base .
The chemical synthesis  of 4-HO-DBT has been described.[ 1]  
 
Several different isomers  of 4-HO-DBT could be made, including 4-HO-DiBT, 4-HO-DsBT , and 4-HO-DtBT, but of these only the isobutyl  isomer 4-HO-DiBT was synthesized  by Alexander Shulgin  (melting point  152 to 154  °C) and was also found to be inactive at a 20  mg dose.[ 1]   The serotonin receptor  interactions of these isomers have been studied.[ 2]  
4-HO-DBT was first described in the scientific literature  by David Repke  and colleagues in 1977.[ 3]
