6-APB & 5-APB ('Benzofury')

History

‘Benzo Fury’ has only been available for sale to the public for the past few years, with 5-APB having been patented by Karin Briner et al in 2000.

Products sold as ‘Benzo Fury’ have been revealed to contain other substances, either alongside or instead of 5 & 6-APB, such as MDAI, 5-IAI, methoxetamine, benzocaine and MPA. Some of these will have similar effects to 5 & 6-APB, but others will simply be present because they look similar to them.
