Can Marijuana Cause Psychosis?

Psychosis is a mental disorder that causes the individual to suffer a disconnect from reality. This condition can occur from mental illness but may also be induced by marijuana use. Some of the most common symptoms are delusions, hallucinations, incoherent talking, and agitation. Research has shown that people who suffer with mental health conditions and use substances may be at higher risk for substance induced psychosis. This suggests that substances like marijuana can affect those with a predisposed risk for psychotic episodes. Using marijuana has also been shown to increase the risk of developing certain mental health disorders such as Schizophrenia, depression, and substance abuse disorder.

“A study published in the journal The Lancet found that people who smoke high potency marijuana on a daily basis potentially have a five times greater risk of developing psychosis compared to people who have never smoked marijuana.”
