What To Do If Your Kids Accidentally Ingest Tetrahydrocannabinol (THC) Edibles

Sep 14, 2026

As cannabis products become more widely available, edible forms of tetrahydrocannabinol (THC) such as cookies, gummies or chocolate are becoming increasingly common in homes. To children, these may be mistaken for ordinary treats. However, even a small amount of THC can pose serious health risks for young children, making safe storage and quick action if accidental ingestion occurs essential. 

Why Tetrahydrocannabinol (THC) Edibles Can be Dangerous for Children 

Because of their small body size, children are much more sensitive to THC, the psychoactive ingredient in cannabis. This means that even a relatively small dose can cause significant symptoms.

“Children process THC differently than adults,” said Brian Jerusik, D.O., medical director for Inspira’s Emergency Departments in Vineland, Elmer, Bridgeton and Mannington, New Jersey. “Just one edible can contain enough THC to cause serious symptoms in a small child, so suspected ingestion must be taken seriously.”

Parents should be aware of how the symptoms of THC ingestion manifest. Depending on the product, it can take anywhere from 30 minutes to several hours for effects to develop, and symptoms may continue for many hours afterward.

Signs your child may have ingested tetrahydrocannabinol (THC)

Accidental THC ingestion can affect every child differently. Common signs include:

  • Excessive sleepiness or difficulty waking up
  • Confusion or unusual behavior
  • Poor coordination or trouble walking
  • Slurred speech
  • Dizziness
  • Nausea or vomiting

In severe cases, children may experience slowed breathing, seizures, or difficulty waking. If your child is experiencing any of these symptoms, dial 9-1-1 immediately. 

“With THC ingestion, symptoms don’t appear right away,” said Dr. Jerusik. “If you suspect your child may have ingested THC, don’t wait for symptoms to become severe before seeking medical guidance.”

What should you do if you think your child ingested THC? 

If you believe that your child may have consumed a cannabis product, it’s important to remain calm and act quickly.

First, remove any remaining product from your child's reach and determine what they may have eaten, including the product packaging if available. Knowing the THC concentration can help healthcare providers determine the best course of action.

If your child is awake and behaving normally, contact Poison Control right away for guidance. They can help determine whether your child can be safely monitored at home or needs medical evaluation.

If your child is difficult to wake, has trouble breathing, experiences a seizure or loses consciousness, call 9-1-1 or go to the nearest emergency department immediately.

Do not try to make your child vomit or give them food or drinks in an attempt to counteract the THC. Instead, follow the instructions provided by Poison Control or your healthcare provider.

How to prevent accidental THC ingestion 

The best way to prevent accidental ingestion is by preventing access to cannabis products altogether. Store all THC-containing products in their original child-resistant packaging and keep them locked away out of both sight and reach. Avoid leaving edibles in places where children may already look for snacks, such as kitchens, purses or backpacks.

“A good rule of thumb is to treat cannabis products the same way you would prescription medications,” said Dr. Jerusik. “Keep them locked up, clearly labeled and out of reach.”

When emergency care is needed

Prompt medical evaluation is important whenever THC ingestion is suspected. Emergency physicians can monitor your child's breathing, heart rate and neurological status while providing supportive care until the effects wear off.

If you're ever unsure whether your child's symptoms are serious, it's always better to seek medical advice. Early evaluation can provide peace of mind and ensure your child receives the care they need.
