A 22-year-old man died after extensively vaping the synthetic cannabinoid 4F-MDMB-BINACA, developing severe necrotizing pancreatitis, acute kidney injury, and multiple organ failure.

Death from multi-organ failure 11 days after synthetic cannabinoid vaping
What the researchers found
Following extensive vaping of 4F-MDMB-BINACA, the patient developed fulminant necrotizing pancreatitis, acute tubular necrosis, cerebral edema, hepatocellular necrosis, and acute respiratory distress syndrome. He died 11 days after admission. The toxicity may stem from CB1 receptor overstimulation or fluoride release from the compound.
Why it matters
This represents the first clinicopathological description of a lethal 4F-MDMB-BINACA intoxication, highlighting the extreme dangers of high-potency synthetic cannabinoids compared to plant cannabis.
The numbers in context
Patient age: 22. Time to death: 11 days post-admission. Identified pathology: necrotizing pancreatitis, acute tubular necrosis, cerebral edema, hepatocellular necrosis, ARDS.
How the study worked
Case report with postmortem histopathology, toxicological analysis, and review of clinical course. Metabolites were confirmed in urine and serum, and the source drug was identified in vapor fluid found at the residence.
What this study cannot tell us
Single case report. Cannot determine exact dose consumed. Two potential toxicity mechanisms (CB1 overstimulation vs. fluoride toxicity) remain unresolved.
How to read the evidence
Single case report with thorough postmortem examination and confirmed toxicology.
When this study was published
Published in 2021.
The bigger picture
Synthetic cannabinoids are far more potent than plant-derived THC and carry risks of multi-organ failure and death that are essentially absent with natural cannabis use.
Questions still open
- Does the fluorine atom in 4F-MDMB-BINACA release toxic fluoride during metabolism? How many unreported deaths from synthetic cannabinoids go undetected?
Common questions
What is 4F-MDMB-BINACA?
How does synthetic cannabinoid toxicity differ from natural cannabis?
