Summary
AMB-FUBINACA is among the most potent synthetic cannabinoids known (CB1 K i ≈0.9 nM). A few milligrams can dose hundreds of people; weighing with a scale no better than 1 mg is unsafe—volumetric or pre-dilution onto inert herb is essential. Responsible for >50 fatalities in New Zealand (2017–2019) and the 2016 “zombie” outbreak in Brooklyn, USA.
Dose Information
| ROA | Threshold |
|---|---|
| Smoked | <50µg |
| Vaporized | <50µg |
| Oral | 100µg |
Only a threshold dose is documented for this substance — the smallest amount with a noticeable effect. There is no published light/common/strong ladder to show above it.
