If you or someone you know is showing signs of cannabis psychosis, get medical help the same day. Call 911 or go to the nearest emergency room when there is agitation, threats of self-harm or violence, or confusion that will not settle. If the person is calm and safe, call the SAMHSA National Helpline at 1-800-662-4357, or call or text 988 to reach a crisis counselor who can point you to a same-day evaluation.
High THC vs Low THC: Psychosis Risk Comparison
What counts as cannabis psychosis?
Cannabis psychosis means hallucinations, delusions, or severe paranoia that begin during or soon after using cannabis. Clinicians call it cannabis-induced psychotic disorder when the symptoms are not better explained by another condition such as schizophrenia or bipolar disorder. It differs from a bad high or ordinary anxiety because the person loses contact with reality and may not know they are impaired.
When is it a medical emergency?
Treat these signs as an emergency and call 911 right away:
can cannabis cause permanent psychosis
- Talking about suicide or about hurting someone else
- Hearing voices or believing other people are controlling their thoughts
- Extreme agitation, panic, or confusion that does not ease
- Seizures, fainting, chest pain, or trouble breathing
- Unable to stay safe or meet basic needs for food, water, or shelter
How do you get help step by step?
- Make the space safe. Remove cannabis, vapes, edibles, and any weapons. Keep the person in a quiet room with one or two familiar people and dim light.
- Call for help. Use 911 for danger, 988 for crisis support, and 1-800-662-4357 for treatment referrals and local options.
- Go to an emergency room or urgent care. Ask for a psychiatric evaluation along with a urine or blood test to rule out other causes.
- Do not argue with the delusion. Say you hear them, that they are safe, and that help is on the way.
- Tell the care team exactly what was used. Product type, THC level, dose, edibles versus flower versus concentrates, plus alcohol or other drugs.
Who treats cannabis psychosis?
Emergency physicians and psychiatrists handle the first evaluation and decide whether the person needs to stay for observation. After that, care usually moves to a psychiatrist, an addiction medicine specialist, or an outpatient mental health program. A therapist trained in cognitive behavioral therapy for psychosis can teach coping skills and help prevent another episode.

What does treatment involve?
No medication is approved specifically for cannabis psychosis, so doctors treat the symptoms. Short-term antipsychotics or anti-anxiety medication may be used, along with sleep, fluids, and a calm, low-stimulation setting. Stopping cannabis is the foundation of recovery, and counseling plus peer support helps people stay off it.
How long does cannabis psychosis last?
Symptoms from a single heavy dose often fade within hours to a few days as the drug clears the body. Episodes tied to daily high-THC use or concentrates can last for weeks. Repeated episodes raise the risk of a longer-term psychotic illness, especially for people who start young or have a family history of psychosis.
What if the person refuses help?
In most US states, a family member, doctor, or police officer can request an emergency psychiatric hold when someone is a danger to themselves or others. That hold is often about 72 hours and includes an evaluation. Laws and paperwork differ by state, so ask the hospital social worker or your county crisis line what applies where you live.
How do you lower the risk of another episode?
- Avoid THC, especially high-potency concentrates, dabs, and edibles
- Check CBD product labels for THC content, since trace amounts can trigger symptoms in sensitive people
- Protect sleep and reduce stimulants like heavy caffeine and energy drinks
- Get treatment for anxiety, depression, or trauma that may drive use
- Keep every follow-up appointment, even after you feel normal
