If a Child Eats a Hemp Gummy: Immediate Poison-Control Information

Call Poison Control Right Away — Don’t Wait for Symptoms

If a child has eaten a hemp gummy, a THC gummy, or any cannabis edible, call Poison Control at 1-800-222-1222 now. Call even if the child looks fine. Symptoms from an edible can take 30 minutes to two hours to show up, and calling early gives the child the best chance of getting help before things get worse. If the child is having trouble breathing, can’t be woken up, or is having a seizure, call 911 instead.

Terms to Know

THC (tetrahydrocannabinol): The compound in cannabis and some hemp products that causes intoxicating effects. It is the main reason edibles are dangerous for children.
Edible: Any food or candy-like product infused with THC or other cannabinoids, including gummies.
Unintentional exposure: The term poison control centers use when a child eats a substance by accident, without knowing what it is.
Poison Control: A free, confidential 24-hour phone and online service staffed by pharmacists and nurses trained to advise on accidental ingestions. It is not the same as calling 911.
Copycat packaging: Cannabis edibles made to look like well-known candy or snack brands, which makes them easy for a child to mistake for regular food.

Edible vs. Inhaled Cannabis: Why the Timing Is Different

Parents sometimes expect a child to show symptoms right away, the way they might after inhaling smoke. Edibles work differently. Here is how the two compare, based on published poison-control guidance:

Onset with edibles: Effects are slower and less predictable, often appearing 30 minutes to two hours after ingestion.
Onset with inhaled cannabis: Effects tend to appear within minutes.
Why this matters for edibles: A child who ate a gummy can look completely normal for a while and then become drowsy, unsteady, or confused later. Waiting to see if symptoms appear before calling Poison Control delays the guidance you need.
Duration: Symptoms from edibles can last for hours, and in some children, longer than that.

Step-by-Step: What to Do If a Child Ate a Hemp or THC Gummy

Move the child to a safe place. Take away any remaining product so the child can’t eat more.
Save the package. Keep the wrapper, container, or bag. It may show the THC amount per serving and per package, which Poison Control or a doctor will likely ask about.
Note the time and estimated amount. Write down when you think the child ate it and roughly how much (for example, one gummy versus most of a package).
Call Poison Control at 1-800-222-1222, or use the online tool at webpoisoncontrol.org. Do this even if the child shows no symptoms yet. Have the package, the child’s age and weight, and your timing notes ready.
Follow the guidance you’re given. Poison Control may advise home monitoring, a call to your pediatrician, or a trip to an emergency department, depending on the amount involved and the child’s age.
Watch the child closely for several hours afterward, even if the first call didn’t lead to an ER visit, since symptoms can appear or worsen later.
Call 911 immediately if severe symptoms develop at any point (see the next section).

Signs That Need Immediate Emergency Care

Call 911 or go to the nearest emergency department right away if the child shows any of the following:

Extreme sleepiness or can’t be woken up
Trouble breathing, or breathing that looks unusually slow or shallow
A seizure
Bluish or pale skin color
Unresponsiveness

Common but less severe effects reported after a child’s cannabis edible exposure include vomiting, dizziness, unsteady walking, a fast heart rate, drowsiness, and confusion. These still warrant a call to Poison Control, even if they don’t require an ambulance.

What the Data Shows

This isn’t a rare event. According to the FDA, between January 1, 2021, and May 31, 2022, national poison control centers logged 10,448 single-substance cases involving edible products containing THC. Of those, 77 percent involved people age 19 or younger, and 91 percent of the unintentional exposures affected pediatric patients specifically. About 79 percent of the total cases needed evaluation at a healthcare facility.

Separately, published poison-control guidance notes that younger children — especially those under age 10 — are more likely than older children to need hospital admission and breathing support after an edible exposure. Reported effects have ranged from vomiting and confusion to, in severe cases, dangerously low heart rate and blood pressure.

Part of the problem is packaging. The FDA has documented THC-infused products made to resemble well-known candy and snack brands, including copycats of familiar cereal, candy, and snack packaging. This kind of packaging makes it easy for a young child to mistake an edible for a regular treat, which is one reason accidental ingestions keep happening even in households where a caregiver believed the product was stored safely.

Reducing the Risk of a Repeat Incident

Store all cannabis and hemp edibles in their original, labeled packaging — never transfer gummies to an unmarked container.
Keep edibles in a location a young child cannot reach or see, ideally locked, separate from other food.
Avoid using or storing edibles that are packaged to resemble popular candy or snack brands.
Tell other caregivers, grandparents, or babysitters where products are stored and what they look like, so they can recognize and secure them too.
