If you believe your child needs immediate attention and you have concerns for a life-threatening emergency, call 911. Not sure what counts as urgent and what's an emergency when your child is sick or injured? When it can't wait, know where to take your kids.
Marijuana (also known as cannabis, weed or pot) is a plant that is commonly used for its psychoactive effects. It is also used medicinally for conditions like chronic pain, cachexia and seizures.
There are various ways to consume marijuana, which include inhalation through smoking or vaporization, and ingestion in edible forms such as baked goods, candies and beverages. Exposure of marijuana products to kids and teens in Colorado has increased over the past several years since the increased availability of both medical and recreational marijuana in Colorado.
*Note to parents and caregivers: Marijuana should be treated as any other drug or medicine, and should be kept out of reach of children. Learn more about safe storage.
What is acute marijuana intoxication?
Acute marijuana intoxication occurs when a person experiences immediate adverse effects from marijuana. This typically occurs after smoking or ingesting marijuana products, and can occur at all ages, and to naïve and chronic users.
Delta-9-tetrahydrocannabinoid (commonly known as THC) is the main psychoactive component in marijuana and is responsible for most symptoms seen after marijuana use. This is the chemical that causes the marijuana "high".
THC affects many different areas of the brain, which leads to the symptoms of marijuana intoxication like increased appetite, changes in mood, sleepiness and balance problems.
After smoking or inhaling marijuana, the onset of symptoms is quick (within 5-30 minutes), but symptoms typically do not last long (a couple of hours).
In contrast, after ingestion of marijuana in the form of food or beverage, the onset of symptoms can take as long as 1-4 hours, and symptoms can last for several hours.
The most common overdose incidents in children occur when the drug has been combined with food in an "edible" form of marijuana. This is because marijuana ingested in this manner can have a stronger and prolonged effect, especially in children under the age of 12.
In these instances, kids mistake "edible" marijuana (like gummy bears, brownies, lollipops, etc.) for regular food and eat it unknowingly. Small children are at higher risk based on their size and weight. Because edible products have very high amounts of marijuana, the symptoms are more severe on a small child. Many young children who consume marijuana edibles require hospital admission due to the severity of their symptoms.
The long-term effect of acute marijuana exposures on children is unknown, as it has not been systematically studied. Because we don’t yet have the research and science findings to know the full effects, doctors do not fully understand marijuana’s long-term effects on children after acute exposures.

Symptoms can range from being unbalanced (loss of coordination), to any degree of sleepiness (from mild drowsiness to being unable to "wake up"), to poor respiratory effort (trouble breathing). Less commonly, children have developed coma and need a breathing tube and ventilator.
Most cases of marijuana intoxication involve young children (of toddler age) and the unintentional ingestion of high-potency edible products. In these instances, kids mistake "edible" marijuana for regular food – like gummy bears, brownies, lollipops, etc. – and eat it unknowingly.
Because edible products have very high amounts of marijuana, the symptoms are more severe in a small child. Many young children who consume marijuana edibles require hospital admission due to the severity of their symptoms.
Because edible products have high concentrations of THC, they can lead to severe symptoms when ingested by a young child. These symptoms can also last much longer than inhaled marijuana.
A urine sample (known as a urine toxicology screen) is typically used to test for marijuana exposure, and it can detect marijuana for days or weeks after use. Bloodwork can also be done to test for the amount of tetrahydrocannabinoid (THC) in the bloodstream.
Urine tests are easy to obtain, and a small amount can be collected when the child urinates. Occasionally, if the child is young or is very symptomatic (has more profound symptoms of marijuana overdose), a urine catheter may need to be placed for medical treatment along with testing.
Healthcare providers at Children’s Hospital Colorado diagnose a marijuana overdose based on a combination of the patient's:
At Children's Hospital Colorado, our goal is to keep kids out of the hospital by educating parents and the community about safe storage to prevent accidental marijuana ingestion.
Marijuana should be treated as any other drug or medicine and kept up high and out of reach of children.
Marijuana and edible products should be kept in their original child-resistant packaging. Furthermore, edible products should not be kept or stored with other non-marijuana food products.
If your child accidentally ingests marijuana, doctors at Children's Colorado recommend the following treatment:
At Children's Colorado, we have sub-specialists in emergency medicine, toxicology, general pediatrics and critical care who have experience in caring for children exposed to marijuana. Our team of experts will work together to ensure your child receives the best care in a compassionate, kid-friendly environment.
