Young children and polysubstance use predicted severe outcomes from pediatric cannabis intoxication

Prospective CohortModerate evidence
The takeaway

Among 138 pediatric cannabis intoxication cases, 38% required ICU admission, with younger age and polysubstance exposure being the strongest predictors of severe outcomes.

Emergency medicine physicians, pediatric toxicologists, cannabis product regulators

38% ICU admission rate; polysubstance use increased severe outcome odds 16-fold

What the researchers found

Of 138 pediatric patients presenting with cannabis intoxication, 52 (38%) were admitted to ICU including one death. Polysubstance ingestion (aOR 16.3) and younger age (P=0.001) were strong independent predictors of severe outcome. All children 10 and younger ingested edibles. Among teens over 10, only polysubstance use predicted severe outcomes (aOR 37.1).

Why it matters

As cannabis legalization expands and edible products proliferate, understanding which pediatric exposures lead to severe outcomes can inform product safety regulations and anticipatory guidance for parents.

The numbers in context

138 patients; 54% male; median age 14.0 years; 38% ICU admission; 1 death; polysubstance aOR 16.3 (95% CI 4.6-58.3); all children <=10 exposed to edibles; teen polysubstance aOR 37.1 (95% CI 6.2-221.2)

How the study worked

Prospective cohort study from the Toxicology Investigators Consortium, collecting data on all pediatric patients (<18 years) presenting with cannabis intoxication from August 2017 to June 2020 across participating US emergency departments. Multivariable logistic regression identified predictors.

What this study cannot tell us

Participating toxicology sites may see more severe cases, overestimating overall severity. Cannot determine population-level incidence rates. Small sample limits subgroup analysis precision. Wide confidence intervals for some estimates.

How to read the evidence

Multi-center prospective study with standardized data collection, but relatively small sample produces wide confidence intervals for some estimates.

The bigger picture

Severe pediatric cannabis outcomes fall into two distinct patterns: young children accidentally ingesting edibles, and teenagers combining cannabis with other substances. Prevention strategies need to address both scenarios differently.

Questions still open

  • Would child-resistant packaging reduce accidental edible ingestions in young children? What specific substances combined with cannabis produce the worst teen outcomes?

Common questions

How serious are pediatric cannabis intoxications?
In this study of 138 cases, 38% required ICU admission and one child died. Young children who ingested edibles and teenagers with polysubstance exposure were at highest risk.
What makes pediatric cannabis cases more dangerous?
Polysubstance use increased the odds of severe outcome 16-fold overall and 37-fold in teenagers. For young children (10 and under), all exposures involved edibles, and younger age itself was a strong predictor.
