What This Study Found

The child showed altered walking, balance, and consciousness after ingesting hashish, followed by respiratory failure. Hair analysis revealed chronic exposure to THC, CBD, CBN, methadone, cocaine, morphine, heroin metabolites, ketamine, and fentanyl.

Key Numbers

Cannabinoids in blood, urine, bile, brain, lung, and liver. Hair positive for THC, CBD, CBN, methadone, cocaine, morphine, 6-MAM, ketamine, and fentanyl.

How They Did This

Forensic case report with autopsy, comprehensive toxicological analysis (immunochemistry, GC-MS, UPLC-MS/MS) of blood, bile, urine, organs, gastric content, and head hair.

Why This Research Matters

While adult cannabis deaths are extremely rare, this case demonstrates cannabis ingestion can be fatal in children, particularly those chronically exposed to multiple substances. It underscores the need for safe storage.

The Bigger Picture

As cannabis legalization expands, accidental pediatric ingestions are increasing. This case, complicated by chronic multi-drug exposure, highlights child welfare concerns.

What This Study Doesn't Tell Us

Single case with confounding chronic drug exposure. Fentanyl and ketamine administered during treatment. Relative contribution of cannabis versus pre-existing exposure unclear.

Questions This Raises

  • ?Would this outcome have occurred without chronic drug exposure?
  • ?What storage regulations could prevent such incidents?

Frequently Asked Questions

Can cannabis kill a child?

This case involved a child who died after ingesting hashish, but chronic exposure to multiple dangerous drugs was a significant complicating factor.

How can accidental ingestions be prevented?

Safe storage, child-resistant packaging, and keeping all cannabis products out of reach are essential.
