What do we know about the link between cannabis and psychosis?

Research has shown that cannabis use impacts psychosis. Psychosis is a break with reality – it could look like hallucinations (seeing, feeling, hearing things that aren’t there), delusions (believing things that aren’t true), impaired thinking and not feeling motivated to do anything.

Cannabis use can cause a temporary psychotic episode in some people – similar to a bad trip.

Unfortunately, we now know that those who have had a bad trip on cannabis are at high risk for developing a psychotic disorder, which is a chronic condition like schizophrenia.

Using cannabis regularly when you’re young does appear to be linked to a chronic life-long psychotic disorder. But, there is currently no way to figure out who is or is not at risk of developing psychosis with cannabis use. What we do know is that people who are already at higher risk because they or a family member has a history of psychosis are at especially high risk if they use cannabis regularly.

The final way that using cannabis is linked with psychosis is that it prevents people who are already diagnosed with a psychotic disorder from feeling better.
