The impact of childhood trauma and cannabis use on paranoia: a structural equation model approach.

Psychological medicine August 8, 2025 Giulia Trotta, Edoardo Spinazzola, Hannah Degen et al. 4 citations

Childhood trauma, especially emotional and physical abuse, is strongly linked to paranoia, and cannabis use amplifies that effect. In a survey of 4,736 adults, those who experienced childhood trauma reported higher paranoia, and weekly cannabis use—measured in standard THC units—also predicted greater paranoia. Cannabis use partially mediated the link between trauma and paranoia, though trauma itself had a much larger direct effect. The findings suggest that assessing both trauma history and cannabis exposure in standard THC units could improve risk detection and guide interventions for people with childhood trauma.

Gene-environment interplay between cannabis and psychosis.

Schizophrenia bulletin November 1, 2008 Cécile Henquet, Marta Di Forti, Paul Morrison et al.

Cannabis use is considered a contributory cause of schizophrenia and psychotic illness, but only a small proportion of users develop psychosis. The amount, duration, and strength of cannabis consumption, as well as age at first exposure, partly explain this. Genetic factors likely play a role in both short- and long-term effects on psychosis. This review discusses studies using genetic, epidemiological, experimental, and observational techniques to investigate gene-environment correlation and interaction within the cannabis-psychosis association. Evidence suggests that mechanisms of gene-environment interaction underlie the link, with multiple genetic variations and other environmental factors (e.g., stress) interacting with cannabis to increase psychosis risk. Further research on higher-order interactions is needed.
