How Cannabis Poisoning Differs Between Children and Adults

Retrospective CohortLow evidence
The takeaway

Children with acute cannabis poisoning more often had impaired consciousness and slow breathing, while adults showed faster heart rates and lower oxygen levels.

Emergency medicine providers, pediatricians, and poison control professionals.

68 of 106 acute cannabis poisoning cases were children, with distinct clinical presentation from adults

What the researchers found

Among 106 patients with acute cannabinoid toxicity (68 children, 38 adults), children more frequently presented with impaired consciousness and bradypnea, while adults showed tachycardia, low oxygen saturation, hypokalemia, and leukocytosis. Delayed medical intervention was a significant risk factor for complications and longer hospital stays in children.

Why it matters

As cannabis access expands, accidental pediatric exposures are increasing. Understanding how poisoning presents differently in children versus adults helps emergency departments provide faster, more appropriate care.

The numbers in context

106 total patients: 68 children, 38 adults over 5 years. Children had significantly more impaired consciousness and bradypnea. Adults had significantly more tachycardia, low oxygen saturation, hypokalemia, and leukocytosis (all p < 0.001). Only 4 cases involved synthetic cannabinoids.

How the study worked

Five-year retrospective study (2019-2023) at a single Egyptian poison control center reviewing medical records of patients admitted for acute cannabinoid toxicity. Patients divided into pediatric (18 and under) and adult groups.

What this study cannot tell us

Single center in Egypt, which may not reflect exposure patterns in other regions. Retrospective design limits data quality. Natural and synthetic cannabinoid cases were mixed. Small sample size for the synthetic cannabinoid subgroup (n=4).

How to read the evidence

Single-center retrospective study with moderate sample size. The Egyptian setting may limit applicability to other populations.

When this study was published

2025 publication with data from 2019-2023.

The bigger picture

Pediatric cannabis exposures have risen sharply in jurisdictions with legal cannabis markets, driven largely by accidental ingestion of edibles. The distinct clinical presentations in children underscore the need for age-specific emergency protocols.

Questions still open

  • How do edible-specific poisoning presentations differ from smoked cannabis toxicity in children?
  • Would standardized screening protocols reduce the delay to medical intervention in pediatric cases?
