Cannabis can affect people very differently. One person may feel relaxed after using it, while another may become frightened, confused, extremely sleepy, nauseated, or unable to function normally. When someone has consumed more cannabis than their body can comfortably handle, knowing what to do next can make the situation feel less overwhelming.
Cannabis intoxication treatment usually involves supportive care while the effects of cannabis wear off. For mild intoxication, this may include stopping further cannabis use, resting in a calm and safe environment, and having a sober person nearby. More serious reactions, including difficulty breathing, loss of consciousness, severe confusion, seizures, chest pain, or extreme agitation, require prompt medical attention. In a medical setting, treatment focuses on monitoring the person and managing individual symptoms because there is no standard antidote that immediately reverses cannabis intoxication.
Most uncomplicated cases improve with time and supportive care. However, you do not need to wait for a situation to become an obvious emergency before asking for guidance. Understanding what you can safely do at home, what you should avoid, and when professional help is needed can help protect the person experiencing the reaction.
What Is Cannabis Intoxication Treatment?
Cannabis intoxication treatment is care provided to keep a person safe and manage uncomfortable or potentially dangerous effects after cannabis use. This may also be described as treatment for marijuana intoxication, especially when someone is experiencing acute effects from THC or another cannabinoid. In many uncomplicated cases, no specific medical treatment is necessary. Observation, reassurance, and protection from injury may be enough while the body processes the psychoactive effects of cannabis.
The appropriate level of care depends on the situation. The amount consumed, THC strength, method of use, other substance use, and the person’s overall health can all affect how intoxication develops and whether there is concern about toxicity. Someone who has had cannabis through edible ingestion may also have a different experience from someone who smoked or vaped marijuana, because edible THC is absorbed more slowly and its effects can last longer.
This is one reason it is important to pay attention to the person and their response to marijuana use rather than simply asking how much cannabis they consumed.
What Should You Do If Someone Is Too High?
If someone is having an uncomfortable reaction to cannabis or marijuana but is awake, breathing normally, and not showing signs of a medical emergency, a few simple steps may help keep the situation from becoming more stressful.
Stop Further Cannabis Use
The first step is to stop using cannabis.
Do not take another edible, smoke more marijuana, or use additional THC in an attempt to change how the person feels. With edibles especially, effects may continue developing after the person has stopped consuming the product because THC can take longer to reach its full effect. This is especially important if the person has recently ingested a cannabis edible and is tempted to take more because they do not feel the effects yet.
Avoid adding alcohol or recreational drugs as well. Combining cannabis with substances that cause sedation can increase drowsiness and impairment.
Move to a Calm, Safe Environment
Someone who is frightened or paranoid may become more distressed in a noisy, crowded, or stimulating environment.
If possible, move to a quiet and familiar space. Encourage the person to sit or lie down somewhere safe. Speak slowly and calmly. Simple reassurance can be helpful, particularly when panic is part of the reaction.
You might remind the person that you are staying with them and that the effects of cannabis are temporary.
Have a Sober Person Stay Nearby
A person who is significantly intoxicated should not drive, operate machinery, or do anything that requires quick judgment or coordination.
Having a sober person nearby also makes it easier to notice if the situation changes. Pay attention to whether the person becomes increasingly confused, difficult to wake, unusually agitated, or develops breathing problems.
Preventing injury and providing reassurance are important parts of supportive treatment for cannabis intoxication.
What Should You Avoid During Cannabis Intoxication?
When someone is uncomfortable during acute intoxication, it can be tempting to try anything that promises to make the high disappear quickly. Unfortunately, there is no reliable home remedy that instantly reverses cannabis toxicity or marijuana toxicity.
Avoid:
- Taking more cannabis
- Drinking alcohol or using other recreational substances
- Driving or operating machinery
- Leaving a severely impaired person alone
- Encouraging someone to “walk it off” if they are dizzy or unsteady
- Giving food or drinks to someone who is unconscious or cannot swallow safely
- Assuming serious symptoms are harmless simply because cannabis was involved
Extra caution may be needed after edible cannabis or marijuana ingestion, since the effects can be delayed and may last longer than expected. Products containing synthetic cannabinoids can also produce unpredictable and potentially more serious adverse effects.
Most importantly, do not ignore sudden or serious side effects because you believe the person is “just too high.” Cannabis may not always be the only substance involved, and another health problem can happen at the same time.
When Should You Get Medical Help for Cannabis Intoxication?
Many uncomfortable cannabis reactions improve without emergency treatment. However, certain symptoms deserve immediate medical attention.
Call 911 or your local emergency number if the person:
- Has difficulty breathing
- Cannot be awakened
- Loses consciousness
- Has a seizure
- Has chest pain
- Collapses or faints
- Becomes severely confused
- Develops extreme agitation or unsafe behavior
- Experiences severe hallucinations or psychotic symptoms
- Has symptoms that are rapidly getting worse
MedlinePlus specifically advises emergency care if someone who has used cannabis has trouble breathing or cannot be awakened.
Medical evaluation is also especially important when you do not know exactly what was consumed, another drug may have been involved, or the product came from an unknown source.
Children require additional caution. Cannabis edibles can cause serious and potentially life-threatening effects in young children, and Poison Control recommends contacting them immediately if a child has consumed a cannabis edible, even if symptoms have not appeared yet.
When in doubt, it is appropriate to ask for professional guidance.
Can You Call Poison Control for Cannabis Intoxication?
Yes. If you are in the United States and someone has an unexpected or concerning reaction to cannabis, you can contact Poison Control at 1-800-222-1222 for individualized guidance. The service is free and confidential.
If possible, have information ready about:
- The person’s age and approximate weight
- The cannabis product involved
- How much may have been consumed
- THC concentration, if known
- When the cannabis was used
- Current symptoms
- Any alcohol, medications, or other substances that may also have been taken
Poison Control can help you determine whether the person can continue to be observed where they are or needs medical evaluation.
If the person is unconscious, having difficulty breathing, having a seizure, or appears to be in immediate danger, call emergency services instead of delaying emergency care.
How Is Cannabis Intoxication Treated at the Hospital?
There is not one single hospital treatment that every person with cannabis intoxication receives. Care is based on the symptoms and severity of the reaction.
For many patients, medical treatment still centers on observation and supportive care while the intoxication resolves.
Monitoring and Medical Evaluation
Healthcare professionals may monitor the person’s:
- Heart rate
- Blood pressure
- Breathing
- Oxygen levels
- Alertness and mental status
Additional testing may be needed when symptoms suggest another medical problem or when healthcare professionals suspect other substances may have been involved.
For example, someone experiencing chest pain may receive an electrocardiogram, or ECG, to evaluate heart activity.
Treating Serious or Uncomfortable Symptoms
Treatment may also focus on individual symptoms.
Depending on the situation, hospital care can include IV fluids, oxygen or other breathing support, medications for significant agitation or anxiety, and other treatments based on the person’s condition. More serious cases may require continued monitoring in the hospital.
Not everyone needs these treatments. The medical team decides what is appropriate after evaluating the person.
How Long Does Cannabis Intoxication Last?
There is no single recovery timeline that applies to everyone.
How cannabis was consumed matters. When cannabis is smoked or vaped, effects usually begin relatively quickly. Edibles are absorbed more slowly, and their effects may develop later and persist longer. The exact timing can vary considerably between individuals and products.
Dose, THC potency, tolerance, metabolism, and other substances can also influence how long someone feels impaired.
Even when someone begins feeling better, they should avoid driving or other risky activities until the effects have fully passed.
If symptoms remain unusually intense, continue getting worse, or last much longer than expected, contact a healthcare professional or Poison Control for guidance.
What Happens After the Intoxication Wears Off?
One difficult experience with cannabis does not automatically mean someone has cannabis use disorder.
Still, the experience can provide useful information.
You might consider what happened before the intoxication. Was the THC stronger than expected? Was an edible taken and then another dose consumed before the first one had fully taken effect? Was cannabis mixed with alcohol? Was the person using cannabis to cope with anxiety, stress, sleep problems, or difficult emotions?
Looking at the circumstances without shame can help reduce the chance of another frightening experience.
If episodes of severe intoxication keep happening, cannabis use feels difficult to control, or cannabis is beginning to interfere with work, relationships, responsibilities, or mental health, speaking with a healthcare or mental health professional may be worthwhile.
When Cannabis Use Becomes More Than an Isolated Incident
Needing help after cannabis intoxication does not automatically mean someone has an addiction. What matters is the larger pattern.
Concerns may be worth exploring when someone repeatedly uses more cannabis than intended, struggles to cut back, experiences strong cravings, continues using despite problems, or increasingly depends on cannabis as their main way of handling stress or difficult emotions.
These patterns can be signs that something more than an occasional episode of intoxication is happening. A professional evaluation can help determine what kind of support, if any, would be useful.
Seeking help does not have to begin with a dramatic decision. Sometimes it simply begins with an honest conversation about what cannabis is doing for you, what it may be costing you, and whether you want your relationship with it to change.
Final Thoughts
Cannabis intoxication treatment is often about keeping the person safe and comfortable while the effects wear off. Mild reactions may improve with time, reassurance, a calm environment, and sober supervision. Severe symptoms such as trouble breathing, inability to wake, seizures, chest pain, or extreme behavioral changes should be treated as medical emergencies.
You don’t have to wait for repeated crises to ask for support. If cannabis use is affecting your mental health, relationships, responsibilities, or ability to feel in control, consider talking with a qualified healthcare or mental health professional. Understanding what is happening is an important first step toward deciding what kind of support may help.
