5-MAPB
5-MAPB is a synthetic entactogen of the substituted benzofuran and amphetamine classes. It is the N-methylated form of 5-APB, structurally analogous to how MDMA relates to MDA. First encountered as a designer drug around 2010, it produces euphoric, entactogenic, stimulating, and mildly hallucinogenic effects. It has been described as one of the closest known analogues to MDMA in terms of subjective quality and has been patented for potential therapeutic use.
