Cannabis-induced psychotic disorder is a type of substance/medication-induced psychotic disorder. It may be diagnosed when hallucinations or delusions develop during or soon after cannabis intoxication or withdrawal and aren’t better explained by another psychotic disorder, mood disorder, delirium or medical condition. If cannabis use is connected to fear, unusual beliefs, hearing or seeing things others do not or major behavior changes, mental health support may help you understand what is happening and what level of care may fit.
This topic deserves careful language. Cannabis does not affect everyone the same way. Still, some people may experience serious mental health symptoms during or after use, especially with frequent use, high-THC products or existing vulnerability.
7 important facts about cannabis-induced psychosis
1. Psychosis means some loss of contact with reality
Psychosis refers to symptoms that affect the mind when there has been some loss of contact with reality. A person may have trouble knowing what is real and what is not.
Symptoms may include:
- Delusions — Fixed beliefs despite contradictory evidence and aren’t better explained by the person’s cultural or religious context.
- Hallucinations — Hearing, seeing or sensing things others do not
- Paranoia — Feeling watched, threatened or targeted
- Disorganized thinking — Trouble organizing thoughts or speech
- Behavior changes — Acting in ways that seem unsafe or very different
These symptoms do not prove one specific diagnosis. They do mean a clinical evaluation may be helpful.
2. Cannabis can be linked with paranoia and psychosis symptoms
Cannabis use can cause disorientation, anxiety and paranoia. Cannabis use is associated with an increased risk of psychosis and longer-term psychotic disorders, including schizophrenia, particularly when use begins earlier or occurs more frequently. However, this association doesn’t mean cannabis causes schizophrenia in every case. Genetic vulnerability and other individual or environmental factors may also contribute, and causation has not been fully established.
This does not mean cannabis use automatically leads to psychosis. Risk can vary based on age, frequency of use, THC potency, personal mental health history, family history, sleep loss and other substance use.
3. High-THC products may increase concern
THC is the main mind-altering chemical in cannabis. Today’s marijuana has much higher THC levels than in past decades and that stronger THC can have stronger effects on the brain.
High-THC products may include concentrates, dabs, waxes, oils or some edibles. Edibles can also be risky because effects may be delayed. A person may take more before they feel the full impact.
4. Symptoms may happen during use or after use
Cannabis-related psychosis symptoms may appear while someone is intoxicated. For some people, symptoms may continue after the cannabis effects seem to wear off.
It may be time to seek support if someone:
- Feels watched, chosen, controlled or threatened
- Hears voices or sees things others do not
- Believes cannabis revealed secret messages
- Stops sleeping or acts in unusually risky ways
- Pulls away from trusted people
- Feels unable to stay safe
A mental health evaluation can help clarify whether symptoms are substance-related, part of another condition or connected to several factors.
5. Cannabis use and psychosis may need care together
When psychosis symptoms and cannabis use both affect daily life, care may need to address both. People with psychosis and coexisting substance misuse should receive evidence-based treatment for both concerns.
Care may include therapy, psychiatry, medication support, substance use support, family involvement or a higher level of care. The right plan depends on symptoms, safety, daily functioning and readiness for change. It can also depend on whether symptoms have happened before, whether cannabis use feels hard to stop and whether trusted people have noticed changes. Asking good questions can help when comparing treatment options.
6. Stopping cannabis suddenly may not be simple for everyone
Some people can stop or reduce cannabis use with support from outpatient providers. Others may need more structured help, especially if cannabis use feels hard to control or symptoms return when they try to stop.
If psychotic symptoms occur during or after cannabis use, avoid further exposure and seek prompt medical or psychiatric evaluation. People who use cannabis frequently may experience withdrawal symptoms after stopping, such as irritability, anxiety or sleep problems and a clinician can help manage these symptoms and assess for cannabis use disorder. A care team can help you plan for safety, sleep, coping skills and support from trusted people.
Daily habits that support mental health may also help create steadier routines while seeking care.
7. Know when to seek urgent help
Seek urgent help if cannabis use is connected to hallucinations, delusions, severe paranoia, no sleep, suicidal thoughts, self-harm urges or commands to hurt yourself or someone else.
If you may not be able to stay safe, call or text 988 to reach the Suicide & Crisis Lifeline, call 911 or go to the nearest emergency room.
