Title: A Candy-Induced Coma: A Case of Accidental Pediatric Intoxication with THC and HHC

Background: Synthetic cannabinoids are potent psychoactive substances that can cause severe neurological depression, particularly in the pediatric population. Recently, accidental pediatric exposures have significantly increased due to the availability of these substances in appealing edible forms, such as candies. Here, we present a pediatric case of severe altered mental status where the underlying etiology was uncovered through meticulous clinical deduction and targeted anamnesis.

Case Presentation: A previously healthy 6-year-old girl was brought to the pediatric emergency department with altered mental status, having been unarousable since falling asleep the previous evening.  The patient was unresponsive to verbal and painful stimuli, although spontaneous breathing and bilateral pupillary light reflexes were intact. Vital signs were within normal limits for her age. On physical examination, we found no abnormal findings other than a GCS score of 9. Point-of-care glucose was 95 mg/dL. The preliminary history obtained from the family revealed no toxic exposure or suspected substance ingestion. Initial laboratory tests, cranial computed tomography, and diffusion magnetic resonance imaging were normal, despite persistent altered consciousness. Subsequently, a toxicological analysis revealed cannabinoid positivity. A more detailed history later uncovered that the child had accidentally consumed an uncle’s candy containing tetrahydrocannabinol (THC) and hexahydrocannabinol (HHC) approximately three hours before symptom onset (17 pieces, each containing 25 mg of HHC). The patient was admitted to the pediatric intensive care unit for close monitoring and supportive therapy. After 72 hours of follow-up, the patient recovered with full consciousness.

Conclusion: To our knowledge, the dosage described in this report surpasses all previously documented cases of THC intoxication in children, underscoring the evolving challenges in managing extreme pediatric exposures. As the availability of synthetic cannabinoid products continues to rise, deepening the anamnesis in unresponsive pediatric patients will help avoid unnecessary and expensive diagnostic investigations.
