6-MAPB
6-MAPB is a psychedelic and entactogenic drug which is structurally related to 6-APB and MDMA. It is not known to have been widely sold as a "designer drug" but has been detected in analytical samples taken from individuals hospitalised after using drug combinations that included other benzofuran derivatives. 6-MAPB was banned in the UK in June 2013, along with 9 other related compounds which were thought to produce similar effects.
