Delta-8, delta-10, and THC-O acetate poison center cases nearly doubled from 2021 to 2022
Poison center reports involving delta-8, delta-10, and THC-O acetate increased 89% from 2021 to 2022, with children under 6 accounting for nearly a third of all cases.
Quick Facts
What This Study Found
There were 5,022 reported cases from 2021-2022, with the rate per 100,000 population increasing 89.1% (from 0.55 to 1.04). Children under 6 accounted for 30.1% of cases, with a mode at age 2. Over a third (38.4%) experienced serious medical outcomes. The most common effects were mild CNS depression (25%), tachycardia (23%), and agitation (15.6%).
Key Numbers
5,022 total cases. 89.1% increase in rate from 2021 to 2022. 30.1% involved children under 6. Mode age: 2 years (8.9% of cases). 98.1% involved delta-8 THC. 94.2% were ingestions. 38.4% had serious medical outcomes. 10.3% admitted to noncritical care. 5.3% admitted to critical care.
How They Did This
Analysis of National Poison Data System data on delta-8 THC, delta-10 THC, and THC-O acetate exposures reported to US poison centers from January 2021 through December 2022. Census data were used for population-based rate calculations.
Why This Research Matters
These products became widely available after the 2018 Farm Bill and are often marketed as legal alternatives to delta-9 THC. The rapid increase in poison center calls, especially involving young children, highlights a growing public health concern with limited regulatory oversight.
The Bigger Picture
The Farm Bill inadvertently created a market for hemp-derived psychoactive products that bypass state cannabis regulations. The surge in poisoning cases, particularly among toddlers, underscores the urgency of product safety standards and child-resistant packaging requirements for these products.
What This Study Doesn't Tell Us
National Poison Data System relies on passive surveillance, likely underestimating true exposure rates. Product labeling accuracy for these substances is questionable. Cannot distinguish between products containing what they claim versus mislabeled products.
Questions This Raises
- ?Are delta-8 and related products inherently more dangerous than delta-9 THC, or does the lack of regulation explain the adverse events?
- ?What specific product types (edibles, vapes) are responsible for most pediatric exposures?
- ?Would state-level regulation reduce these poisoning rates?
Trust & Context
- Key Stat:
- 30.1% of poison center cases involved children under 6
- Evidence Grade:
- National surveillance data covering all US poison centers, though passive reporting likely undercounts actual exposures. Product identity verification is limited.
- Study Age:
- Published in 2024 covering exposure data from 2021-2022.

Evidence Hierarchy
Frequently Asked Questions
What are delta-8 and THC-O acetate?
Delta-8 THC and THC-O acetate are psychoactive compounds derived from hemp that became widely available after the 2018 Farm Bill. They produce effects similar to delta-9 THC but exist in a regulatory gray area in many states.
Why are so many children exposed?
These products are often sold as edibles (gummies, candies) that are attractive to children, and many lack child-resistant packaging. Ninety-five percent of cases in children under 6 were ingestions, mostly occurring in homes.
How serious were the poisoning cases?
Over a third (38.4%) experienced serious medical outcomes. About 10% were admitted to noncritical care units and 5.3% to critical care. Common symptoms included drowsiness, rapid heart rate, and agitation.
