What to do first if your child ingested cannabis

If you think your child accidentally ate edible cannabis, try to stay calm and gather the product package if you have it. Check how much may be missing, when your child may have eaten it, and whether they are acting differently. If your child is hard to wake, having trouble breathing, having a seizure, or collapsing, call 911 right away. For non-life-threatening situations, personalized guidance can help you decide what symptoms matter most and whether you should contact Poison Control or seek urgent medical care.

Common signs after a child eats a THC edible

Sleepiness or unusual drowsiness

Many children become much more sleepy than usual after accidental cannabis ingestion. They may seem hard to keep awake, less responsive, or unusually quiet.

Poor balance, confusion, or behavior changes

A child who ate a marijuana gummy may seem wobbly, confused, dizzy, agitated, or not like themselves. Older children may say they feel strange or scared.

Nausea, vomiting, or fast heart rate

Some children have stomach upset, vomiting, or a racing heartbeat. Symptoms can vary depending on the amount of THC and the type of edible.

Why edibles can affect children differently

Symptoms may be delayed

Edibles often take longer to cause noticeable effects than smoked cannabis. A child may seem fine at first and then develop symptoms later.

Small bodies can be affected by small amounts

Even part of a gummy or brownie can cause significant symptoms in a toddler or young child, especially with high-THC products.

Packaging can make it hard to estimate the dose

Cannabis candies, baked goods, and drinks vary widely in THC content. Knowing the product type and strength can help guide next steps.

Information that helps you decide next steps

When it happened

The time since ingestion matters because symptoms from edibles may build over several hours. Recent ingestion may call for different guidance than symptoms that started later.

What product was involved

A marijuana gummy, THC drink, chocolate, or pot brownie may contain different amounts of cannabis. If you have the label, keep it nearby.

What symptoms your child has now

Current symptoms help determine whether home monitoring may be reasonable or whether urgent evaluation is needed.

Frequently Asked Questions

What happens if a child eats cannabis?

Children can develop sleepiness, poor coordination, confusion, vomiting, or behavior changes after eating cannabis. In more serious cases, they may become very hard to wake or have breathing problems, which need emergency care.

My child ate a weed edible but seems fine. Should I still be concerned?

Yes. Edible cannabis can take time to cause symptoms, and children may look normal at first. It’s important to consider when the ingestion may have happened, what product was involved, and whether symptoms appear over the next several hours.

What should I do if my toddler ate a marijuana gummy?

Check the package if available, estimate how much may have been eaten, and watch closely for drowsiness, vomiting, balance problems, or unusual behavior. If your child is difficult to wake, having trouble breathing, or has severe symptoms, call 911. Otherwise, getting personalized guidance can help you decide the safest next step.

How long after a child ingests a cannabis edible do symptoms start?

Symptoms from edibles may begin later than many parents expect and can continue to develop over a few hours. That delay is one reason accidental cannabis ingestion in children can be easy to underestimate early on.
