AMB-FUBINACA (ADB-FUBINACA)

Definition

A third-wave synthetic cannabinoid of the fluorobenzyl indazole carboxamide scaffold identified in the 2016 New York mass-poisoning event; associated with intense, prolonged CB1 receptor activation and serious adverse effects.

Chemical class
Synthetic cannabinoid
Structural scaffold
Fluorobenzyl indazole carboxamide
Notable event
2016 New York mass-poisoning incident
Receptor target
CB1 agonist

Common questions

Why did this compound cause such severe, prolonged effects compared with THC?+

It binds the CB1 receptor with much greater affinity and efficacy than THC and produces sustained receptor activation, which is why users in the 2016 incident presented with an unusually intense, zombie-like sedation lasting far longer than typical cannabis intoxication.

How is this substance identified analytically given it is not a natural cannabis compound?+

Because it does not resemble THC structurally, standard cannabinoid immunoassays often miss it, so confirmation relies on LC-MS/MS or GC-MS comparison against a reference standard for the specific indazole carboxamide analog involved.
