If your child may have eaten a weed gummy, brownie, or other cannabis edible, quick guidance can help you decide what to do next. Learn the warning signs, when to call Poison Control, and how long cannabis edibles can affect children.
Start with what you know about the situation so you can get clear, personalized guidance on symptoms to watch, timing, and when emergency help may be needed.
Edible marijuana poisoning in children can cause stronger and longer-lasting effects than many parents expect. Young children may become unusually sleepy, confused, unsteady, or hard to wake. If your child has trouble breathing, has a seizure, collapses, or cannot be awakened, call 911 right away. If your child is awake and stable, remove any remaining edible, keep the package if available, and get guidance as soon as possible.
A child sleepy after eating an edible may be experiencing cannabis effects. Concerning signs include being difficult to wake, not responding normally, or falling back asleep right away.
Look for confusion, poor balance, unusual limpness, agitation, slurred speech, or trouble walking. These symptoms can happen even with a small amount in a young child.
Slow breathing, vomiting, seizures, or passing out need urgent medical attention. These symptoms can signal a cannabis edible emergency.
If you saw it happen, an edible is missing, or another person told you your child ate one, Poison Control can help you decide the safest next step.
If your child seems unusually sleepy, dizzy, confused, or is acting unlike themselves after possible exposure, get expert guidance promptly.
Dose can be hard to estimate with gummies, chocolates, and baked goods. Packaging, THC amount, and your child’s age and size all matter.
Symptoms do not always start right away. A child may seem fine at first and then become more affected as the edible is absorbed.
Parents often ask how long cannabis edibles affect children. The effects may last much longer than smoking exposure and can continue for many hours.
Because children are smaller and edibles can contain concentrated THC, even part of a gummy or baked item may cause significant symptoms.
If your child has trouble breathing, has a seizure, collapses, or cannot be awakened, call 911 immediately. If your child is awake, remove any remaining edible, keep the package if you have it, and contact Poison Control for guidance. Monitor closely because symptoms can be delayed.
Common symptoms include unusual sleepiness, confusion, poor balance, dizziness, vomiting, and behavior changes. More serious symptoms can include slow breathing, seizures, or being hard to wake.
Cannabis edibles can affect children for several hours, and symptoms may last longer than many parents expect. Onset may be delayed, and the total duration depends on the amount eaten, the THC content, and the child’s age and size.
Call Poison Control as soon as you suspect your child ate a cannabis edible, especially if symptoms are present, the amount is unknown, or the product was high in THC. You do not need to wait for symptoms to become severe before calling.
Sleepiness can be a sign of cannabis exposure in children. If your child is more drowsy than usual, difficult to wake, not acting normally, or has any breathing problems, seek immediate help. If they are awake but unusually sleepy, contact Poison Control for next-step guidance.
