What is MDMB-4en-PINACA?
MDMB-4en-Pinaca ( methyl-3,3-dimethyl-2-(1-(pent-4-en-1-yl) -1H-indazol-3-carboxamido)butanoate) belongs to the indazole carboxamide family, a group of synthetic cannabinoids. It is structurally similar to deadly substances such as 5F-ADB, which have been responsible for mass casualty incidents and overdoses in recent years.
Street names and appearance:
Forms: White, yellow, or brown powder.
Application: Typically sprayed onto plant material (to mimic cannabis), dissolved in e-liquids for vaping, or applied to paper strips. It can also be injected or ingested orally.
Effects of MDMB-4en-PINACA
Because MDMB-4en-PINACA is a full agonist with high binding affinity, its effects are unpredictable and often severe. Preclinical studies show that it is more potent and produces longer-lasting effects than many previous generations of synthetic cannabinoids.
Physical effects:
Consumers often experience a rapid onset of severe physical symptoms, including:
Sedation and unconsciousness: Extreme drowsiness, sudden collapse or breakdown.
Respiratory depression: Slowed or paused breathing, one of the main causes of overdose deaths.
Cardiovascular problems: tachycardia (rapid heartbeat), hypertension, chest pain and internal bleeding.
Neurological symptoms: seizures, salivation, temporary paralysis and hypothermia (drop in body temperature).
Psychological and neurological effects:
Research results indicate that this substance directly damages cognitive function.
Cognition: Studies show that MDMB-4en-PINACA significantly impairs spatial learning and memory.
Psychiatric symptoms: Severe restlessness, confusion, paranoia, hallucinations, and loss of touch with reality.
Brain damage: Preclinical studies have demonstrated pathological degeneration of small pyramidal cells in the cerebral cortex and hippocampus – brain regions that are crucial for memory and learning.
Toxicity and safety risks
The safety profile of MDMB-4en-PINACA is extremely poor. There is no safe dose for human consumption. The toxic dose is estimated to be less than the size of a fingernail. Documented case studies show that even ingestion of this substance alone—without any other drugs—can be fatal.
Organ damage and lethality
in the brain: Histopathological examinations show acute brain damage.
Kidneys: Acute kidney failure has been associated with its use.
Deaths: Documented deaths have occurred in both inpatient and prison settings. At Cook County Jail (USA), MDMB-4en-PINACA has been linked to a number of fatal overdoses in which inmates consumed paper strips laced with the drug. Postmortem blood concentrations as low as 7.2 ng/ml have been found in cases of fatal overdoses.
Legal status:
Schedule I controlled substance.
Due to its high potential for abuse and the lack of recognized medical benefit, MDMB-4en-PINACA is subject to strict controls.
