5F-AMB (also known as 5F-MMB-PINACA and 5F-AMB-PINACA) is an indazole-based synthetic cannabinoid from the indazole-3-carboxamide family,[1] which has been used as an active ingredient in synthetic cannabis products. It was first identified in Japan in early 2014.[2][3] Although only very little pharmacological information about 5F-AMB itself exists,[4] its 4-cyanobutyl analogue (instead of 5-fluoropentyl) has been reported to be a potent agonist for the CB1 receptor (KI = 0.7 nM).[5][6]

Side effects

5F-AMB intoxication caused one fatality on its own[7] and another one through ketoacidosis in combination with AB-CHMINACA, AB-FUBINACA, AM-2201, 5F-APINACA, EAM-2201, JWH-018, JWH-122, MAM-2201, STS-135 and THJ-2201 and another fatality in combination with AB-CHMINACA and Diphenidine.[8][9]


5F-AMB is an Anlage II controlled substance in Germany as of May 2015.[10]

Sweden's public health agency suggested classifying 5F-AMB as hazardous substance on November 10, 2014.[11]

The state of Louisiana banned 5F-AMB through an emergency rule after it was detected in a synthetic cannabinoids product called "Kali Berry 2" on 3 June 2014.[12]

5F-AMB is controlled by the Fifth Schedule of the Misuse of Drugs Act (MDA) in Singapore as of May 2015.[13]

5F-AMB was also scheduled in Japan on July 25, 2014.[14]

As of October 2015 5F-AMB is a controlled substance in China.[15]
