If a child eats a delta-8 gummy, the effects can range from drowsiness and poor coordination to serious complications like breathing problems, seizures, and loss of consciousness. Delta-8 THC produces effects that are qualitatively similar to regular (delta-9) THC in children, and because of a child’s small body weight, even a single gummy can deliver a dangerously high dose. This is a medical emergency: call Poison Control (1-800-222-1222) or 911 immediately.
Symptoms to Watch For
Children who ingest delta-8 gummies can show a wide spectrum of symptoms. On the milder end, a child may seem unsteady on their feet, unusually sleepy, or confused. More concerning signs include rapid heart rate, low blood pressure, seizure-like activity, and weak or slow breathing. In the most severe documented cases, children have become completely unresponsive and required a breathing tube and mechanical ventilation.
In one published case, a young child who ate delta-8 gummies arrived at the emergency department barely responsive to any stimulation, with a heart rate of 136 beats per minute. She required intubation to protect her airway. In another report cited by the FDA, four children presented with confusion, extreme drowsiness, seizure-like activity, low blood pressure, and rapid heart rate after eating retail delta-8 products.
How Quickly Effects Start and How Long They Last
Unlike inhaled THC, which hits peak levels in the blood within about 10 minutes, edible THC reaches peak concentration 2 to 3 hours after it’s swallowed. That delay is important: a child may seem fine at first and then deteriorate rapidly. Symptoms from a typical dose can last 5 hours or longer, but in overdose situations the effects can persist much longer. In one case involving two children admitted to a pediatric intensive care unit after eating delta-8 products that looked like candy, both were not discharged until roughly 45 hours after ingestion.
Why Children Are Hit Harder Than Adults
A standard delta-8 gummy contains anywhere from 10 to 50 mg of THC. For a 15 kg (33-pound) toddler, a single 25 mg gummy delivers about 1.7 mg per kilogram of body weight. That number matters because research from the American Academy of Pediatrics identified 1.7 mg/kg as the threshold above which severe and prolonged toxicity becomes highly likely, with 97% sensitivity for predicting a serious reaction. At 2.3 mg/kg, roughly equivalent to one 35 mg gummy in that same toddler, the risk of severe toxicity climbs further. The dose range that has caused seizures, breathing failure requiring intubation, and dangerous drops in blood pressure spans from 2 to 69 mg/kg.
THC acts on areas of the brain responsible for coordination, memory, and body temperature regulation. A child’s brain is still developing, which makes it especially vulnerable. The same dose that might cause mild intoxication in a 75 kg adult can overwhelm a small child’s nervous system.
What Happens at the Hospital
There is no antidote for THC. Treatment is supportive, meaning the medical team manages symptoms while the drug works its way out of the child’s system. For a mildly affected child, that may mean monitored observation for several hours. For more severe cases, the priority is protecting the airway and maintaining stable breathing and blood pressure. Children with significant drowsiness or breathing problems may receive supplemental oxygen or, in serious cases, mechanical ventilation. IV fluids are given when needed to support blood pressure and hydration.
If the medical team is unsure whether the child also swallowed something else, they may administer a medication to rule out opioid involvement, since the symptoms of THC overdose and opioid overdose overlap. The child will be monitored until they are alert, breathing normally, and their heart rate and blood pressure have stabilized.
This Problem Is Growing Rapidly
Nearly 5,000 delta-8 THC exposures were reported to U.S. poison control centers in 2021 and 2022 combined, and the number jumped 82% from the first year to the second. Children under 6 accounted for 30% of all reported cases, making them the second-largest age group affected. Another 24% involved children and teens aged 6 to 19.
The packaging is a major part of the problem. Many delta-8 gummies are sold in bright, candy-like wrappers that are nearly indistinguishable from regular gummy bears or sour candies. While regulated cannabis markets like California require child-resistant packaging for edibles, delta-8 products are often sold as hemp derivatives in gas stations, convenience stores, and online retailers where no such requirement exists. The FDA has stated that delta-8 THC products have not been evaluated or approved for safe use in any context, and that adding delta-8 to food products makes them adulterated under federal law.
Delta-8 vs. Delta-9: Is One Safer for Kids?
No. Delta-8 is sometimes marketed as “lighter” or “less potent” than delta-9 THC, but the clinical effects in children are qualitatively the same. Both compounds can cause the full range of toxicity, from drowsiness to respiratory failure. The published pediatric case reports involving delta-8 describe outcomes just as severe as those seen with delta-9 edibles, including ICU admission and mechanical ventilation. Treating delta-8 as a milder product is a dangerous assumption when it comes to children.
Keeping Delta-8 Products Away From Children
If you have delta-8 gummies or any THC edibles in your home, store them in a locked container out of reach and out of sight. The resemblance to candy makes these products uniquely attractive to young children who cannot read warning labels. Never transfer gummies into unmarked bags or leave them on countertops, nightstands, or in purses. If you have visitors who use THC products, ask them to keep their supply secured as well.
If your child does eat a delta-8 gummy, bring the packaging with you to the emergency department. Knowing the labeled THC content per gummy and how many are missing helps the medical team estimate the dose and anticipate how severe the reaction may be. Even if your child seems fine initially, the 2- to 3-hour delay before peak effects means symptoms can worsen significantly after you think the danger has passed.
