Can Marijuana Trigger Psychosis? Evidence and Research Insights

A Collective Care Center Blog

Introduction

At Collective Care Center, we are often asked whether marijuana (cannabis) can cause psychosis. With changing laws, rising availability of high-potency cannabis, and growing social acceptance, it’s vital to separate myths from facts. Scientific research shows that while not everyone who uses marijuana will develop psychosis, frequent use—especially of high-THC products or use beginning in adolescence—does increase the risk.

As a trusted dual diagnosis treatment centre in India, we aim to provide clear, evidence-based insights into how marijuana affects the brain and mental health, and how treatment and rehabilitation can support recovery.

What is Psychosis?

Psychosis is a mental health condition where individuals lose touch with reality, often experiencing:

• Hallucinations (seeing or hearing things that aren’t there)

• Delusions (false, fixed beliefs)

• Disorganized thoughts or speech

Psychosis may be short-term (drug-induced) or part of a long-term psychiatric condition such as schizophrenia. Marijuana is one of the most widely studied substances linked to psychotic symptoms.

The Evidence: Marijuana and Psychosis

1. Cannabis Use and Risk of Psychosis

Research, including large meta-analyses, shows a dose–response relationship:

• Frequent use (daily or near-daily) increases risk of psychotic disorders.

• High-potency cannabis (high THC, low CBD) is strongly linked to psychosis compared to low-potency forms.

• Early age of first use (during adolescence, when the brain is still developing) further heightens the risk.

2. Biological Mechanisms

• Dopamine Overactivity: THC stimulates dopamine release in brain circuits linked with hallucinations and paranoia.

• Endocannabinoid Disruption: Cannabis alters CB1 receptor functioning, disturbing balance in brain signaling.

• Genetic Vulnerability: People with a family history of psychosis are more sensitive to cannabis effects.

3. Marijuana as a Trigger

Cannabis doesn’t cause psychosis in everyone. However, in vulnerable individuals, it can trigger the onset of psychosis earlier and worsen long-term outcomes if left untreated.
