Chemical Structure
Where to Buy 5F-ADB-PINACA
IUPAC Name:
N-(1-amino-3,3-dimethyl-1-oxobutan-2-yl)-1-(5-fluoropentyl)-1H-indazole-3-carboxamide
Molecular Formula:
C19H26FN3O3
Molecular Weight:
363.43 g/mol
Structure Overview:
The cannabinoid features an indazole core attached to a 5-fluoropentyl chain at the nitrogen atom and a carboxamide linker bonded to a tert-leucine-derived side chain. The addition of a fluorine atom at the terminal position of the pentyl chain enhances its lipophilicity and receptor binding affinity.
Pharmacology
This cannabinoid acts primarily as a full agonist at CB1 and CB2 cannabinoid receptors, which are part of the human endocannabinoid system.
- CB1 receptors: Located mainly in the central nervous system, responsible for psychoactive effects.
- CB2 receptors: Predominantly in peripheral tissues, especially immune cells.
Binding Affinity:
It exhibits high nanomolar to sub-nanomolar binding affinities, making it significantly more potent than natural THC.
Mechanism of Action:
Once ingested or inhaled, It binds to cannabinoid receptors, triggering effects on mood, perception, pain modulation, appetite, and memory. Due to its full agonist nature, it can produce much stronger and sometimes dangerous effects compared to partial agonists like THC.

- High overdose potential due to extreme potency.
- Increased risk of cardiovascular events, seizures, and death.
- Impairment of judgment and psychomotor skills.
- Potential for dependence and withdrawal symptoms.
Legal Status:
Many countries and regions have placed 5F-ADB-PINACA under controlled substance laws. It is typically classified under Schedule I or equivalent due to its lack of medical use and high abuse potential.
Toxicological Profile:
Cases of intoxication often present with:
- Elevated heart rate
- Hypertension
- Confusion
- Loss of consciousness
- Acute kidney injury
- Multi-organ failure in severe instances
Conclusion
5F-ADB-PINACA represents a dangerous chapter in the evolution of synthetic cannabinoids. While structurally crafted to mimic natural THC, its chemical modifications result in a far more potent and unpredictable profile. The lack of quality control in illicit markets and the compound’s severe health risks have made it a focal point for regulatory agencies and public health officials.
Anyone encountering substances suspected of containing 5F-ADB-PINACA should exercise extreme caution, as even minimal exposure can lead to life-threatening consequences. Its use in recreational settings is strongly discouraged.
