Hexahydrocannabinol (HHC) is a synthetic cannabinoid found in unregulated products. Ingestion caused a 32-year-old male to experience severe dissociative and gastrointestinal symptoms, highlighting the risks of these illicit substances.
Area of Science:
- Toxicology
- Pharmacology
- Cannabinoid Research
Background:
- Hexahydrocannabinol (HHC) is a semi-synthetic derivative of delta-9-tetrahydrocannabinol (THC).
- HHC has recently emerged in unregulated cannabis markets, often found in edible products.
- Its presence in illicit products raises concerns regarding user safety and potential health risks.
Purpose of the Study:
- To report a case of analytically confirmed Hexahydrocannabinol (HHC) exposure.
- To describe the clinical presentation and multi-system toxicity associated with HHC ingestion.
- To emphasize the dangers posed by unregulated psychoactive substances.
Main Methods:
- A case report of a 32-year-old male presenting with acute symptoms after consuming an HHC-containing gummy.
- Clinical examination, symptom assessment, and supportive management.
- Serum analysis to identify the presence and isomers of HHC, excluding other substances.
Main Results:
- The patient exhibited nausea, vomiting, slurred speech, numbness, confusion, tachycardia, and tachypnoea, indicative of a dissociative state.
- Serum analysis confirmed the presence of 9R-HHC and 9S-HHC isomers.
- Symptoms resolved within eight hours with supportive care, with no other psychoactive substances detected.
Conclusions:
- HHC, particularly the 9R-HHC isomer, is psychoactive and rapidly absorbed.
- HHC exposure can lead to multi-system toxicity, including significant gastrointestinal and dissociative neurological effects.
- This case underscores the potential dangers of unregulated HHC products and the need for consumer awareness.
