Various lines of evidence suggest an association between cannabis and psychosis. Five years ago, the only significant case-control study addressing this question was the Swedish Conscript Cohort. Within the last few years, other studies have emerged, allowing the evidence for cannabis as a risk factor to be more systematically reviewed and assessed. Using specific search criteria on Embase, PsychINFO and Medline, all studies examining cannabis as an independent risk factor for schizophrenia…

Cannabis and Psychosis: A Review of the Risk Factors Involved
TLDR
A significant inverse relationship exists between cannabidiol (CBD) and psychosis: cannabodiol is associated with less psychotic symptoms and manifests antipsychotic properties.
Cannabis and Psychosis: What is the Link?
TLDR
Although there is evidence that cannabis use increases the risk of developing psychotic symptoms, the causal nature of this association remains unclear, and this conclusion should be mitigated by uncertainty arising from cannabis use assessment, psychosis measurement, reverse causality and control of residual confounding.
Cannabis psychosis: examining the evidence for a distinctive psychopathology in a systematic and narrative review.
TLDR
These findings do not suggest that "cannabis psychosis" does not exist, only that from a psychopathological perspective it may not be qualitatively any different from other forms of psychosis.
Meta-analysis of the Association Between the Level of Cannabis Use and Risk of Psychosis.
TLDR
Current evidence shows that high levels of cannabis use increase the risk of psychotic outcomes and confirms a dose-response relationship between the level of use and the risk for psychosis, and sufficient evidence to justify harm reduction prevention programs.
Factors Moderating the Association between Cannabis Use and Psychosis Risk: A Systematic Review
TLDR
Cannabis use is associated with an earlier psychosis onset and increased risk of transition in individuals at a clinical high risk of psychosis, indicating that changing cannabis use behavior could be a harm reduction strategy employed to lower the risk of developing psychosis.
Cannabis use and psychosis: a review of reviews
  • A. Hasan, R. Keller, E. Hoch
  • Psychology, Medicine
    European Archives of Psychiatry and Clinical Neuroscience
  • 2019
TLDR
A systematic review of meta-analyses and systematic reviews to evaluate the impact of cannabis use on the onset and course of psychoses found that cannabis use is associated with a dose-dependent risk of developing psychotic illness, and cannabis users have an earlier onset of psychotic illness compared to non-users.
An overview of systematic reviews on cannabis and psychosis: discussing apparently conflicting results.
TLDR
It is concluded that there is insufficient knowledge to determine the level of risk associated with cannabis use in relation to psychotic symptoms and that more information is needed on both the risks of cannabis use and the benefits of preventive interventions to support evidence-based approaches.

Cannabis, Vulnerability, and the Onset of Schizophrenia: An Epidemiological Perspective∗
TLDR
The vulnerability-stress-coping model of schizophrenia suggests possible interpretations of these findings, which suggest patients probably learn to counterbalance a hypodopaminergic prefrontal state by the dopaminergic effects of cannabis.
Cannabis Use and Psychosis: A Review of Clinical and Epidemiological Evidence ∗
TLDR
It is still unclear whether this means that cannabis use precipitates schizophrenia, whether cannabis use is a form of ‘self-medication’, or whether the association is due to the use of other drugs, such as amphetamines, which heavy cannabis users are more likely to use.
Cannabis use and the risk of later schizophrenia: a review.
TLDR
Antecedent cannabis use appears to act as a risk factor in the onset of schizophrenia, especially in vulnerable people, but also in people without prior history.
Cannabis use and psychosis: a longitudinal population-based study.
TLDR
Results confirm previous suggestions that cannabis use increases the risk of both the incidence of psychosis in psychosis-free persons and a poor prognosis for those with an established vulnerability to psychotic disorder.
[Cannabis use as a probable causative factor in the later development of schizophrenia].
TLDR
There are strong indications that cannabis use increases the risk of the subsequent development of symptoms and disorders in the schizophrenia spectrum.
Cannabis use in adolescence and risk for adult psychosis: longitudinal prospective study
TLDR
This is the first prospective longitudinal study of adolescent cannabis use as a risk factor for adult schizophreniform disorder, taking into account childhood psychotic symptoms, and the Dunedin multidisciplinary health and development study has a 96% follow up rate at age 26.
Cannabis Use is Not Associated With the Development of Psychosis in an ‘Ultra’ High-Risk Group
TLDR
This study does not support a role for cannabis in the development of first-episode psychosis, but it cannot conclude that cannabis use should be completely ignored as a candidate risk factor for onset of psychosis.
Effects of cannabis and psychosis vulnerability in daily life: an experience sampling test study
TLDR
Cannabis use interacts with psychosis vulnerability in their effects on experience of psychosis in daily life and there is no evidence that use of cannabis is increased following occurrence of psychotic experiences as would be expected by the self-medication model.
Cannabis use and age at onset of schizophrenia.
TLDR
A strong association between use of cannabis and earlier age at first psychotic episode in male schizophrenia patients is indicated and additional studies examining this possibly causal relationship are needed.
Self reported cannabis use as a risk factor for schizophrenia in Swedish conscripts of 1969: historical cohort study
TLDR
Self reported cannabis use is associated with an increased risk of subsequently developing schizophrenia, consistent with a causal relation This association is not explained by sociability personality traits, or by use of amphetamines or other drugs Self medication with cannabis is an unlikely explanation for the association observed.
