'''6-APDB''' (also known as '''6-(2-aminopropyl)-2,3-dihydrobenzofuran''' or '''4-Desoxy-MDA''') is a [[stimulant]] and [[Psychoactive class::entactogen]]ic [[research chemical]] of the [[Chemical class::phenethylamine]] and [[Chemical class::benzofuran|benzofuran]] classes. It is a closely related synthetic analogue of [[MDA]] and [[6-APB]] and broadly shares the characteristics of serotonin-selective triple [[monoamine releasers]] and [[reuptake inhibitors]] associated with other [[entactogen]]ic or [[empathogen]]ic compounds. | '''6-APDB''' (also known as '''6-(2-aminopropyl)-2,3-dihydrobenzofuran''' or '''4-Desoxy-MDA''') is a [[stimulant]] and [[Psychoactive class::entactogen]]ic [[research chemical]] of the [[Chemical class::phenethylamine]] and [[Chemical class::benzofuran|benzofuran]] classes.

Because 6-APDB and other substituted benzofurans have not been explicitly outlawed in some countries, they are often technically legal, contributing to their popularity as a substitute or replacement for serotonergic entactogens like MDMA or MDA, and are typically distributed through the online research chemicals grey market. | Because 6-APDB and other substituted benzofurans have not been explicitly outlawed in some countries, they are often technically legal, contributing to their popularity as a substitute or replacement for serotonergic entactogens like MDMA or MDA, and are typically distributed through the online research chemicals grey market. | ||

This is done by promoting the release and inhibiting the reuptake and reabsorption of the neurotransmitters after they have performed their function of transmitting a neural impulse through release into the synaptic cleft, essentially allowing them to accumulate and render them liable for immediate reuse. The net result is excitation in a manner which causes a combination of physically stimulating, relaxing, disinhibiting and euphoric effects.<ref>{{cite journal | vauthors=((Fleckenstein, A.

The neurotoxicity of 6-APDB is controversial. It was specifically designed to be less neurotoxic than MDA or MDMA by circumventing the production of certain metabolic byproducts thought to underlie their toxicity (specifically alpha-methyl-dopamine).{{Citation needed}} Although it is likely to be physically safe to try in a responsible context, it is completely possible that the administration of repeated or high dosages of 6-APDB could result in neurotoxic effects in some form, possibly manifesting as deficits in cognitive, affective and psychomotor function. | The neurotoxicity of 6-APDB is controversial.
