Cannabis May Drive Violence in Early Psychosis Through Impulsivity
Cannabis use is a risk factor for violent behavior in early-phase psychosis, with impulsivity potentially mediating this relationship through cannabis effects on frontal brain regions.
Quick Facts
What This Study Found
Cannabis use is particularly high in early-phase psychosis (EPP) and is a confirmed risk factor for violent behavior in this population. Impulsivity is both associated with cannabis use and a risk factor for violence, potentially mediating the cannabis-violence link. Cannabis affects frontal brain structures involved in impulse control.
Key Numbers
Cannabis use is particularly high in EPP; impulsivity mediates the cannabis-violence link; frontal lobe dysfunction involved
How They Did This
Viewpoint review of scientific literature examining the link between cannabis use, violent behavior in psychosis, and the mediating role of impulsivity at clinical and neurobiological levels.
Why This Research Matters
Understanding why cannabis use increases violence risk in early psychosis identifies a targetable mechanism (impulsivity) for prevention, particularly since early-phase psychosis represents a window for intervention.
The Bigger Picture
The early phase of psychosis offers unique prevention opportunities. If impulsivity mediates the cannabis-violence link, interventions targeting both cannabis use and impulse control could reduce violence risk.
What This Study Doesn't Tell Us
Viewpoint/review rather than original data. The mediating role of impulsivity is proposed but needs confirmation with longitudinal studies controlling for confounders.
Questions This Raises
- ?Would impulse-control interventions reduce violence in cannabis-using psychosis patients?
- ?Does the age of cannabis use onset affect the strength of the impulsivity pathway?

What do these levels mean? →Frequently Asked Questions
Does cannabis cause violence in people with psychosis?
Cannabis use is a confirmed risk factor for violent behavior in early-phase psychosis. This review proposes that impulsivity, worsened by cannabis effects on frontal brain regions, may explain this link.
Can this risk be reduced?
The review highlights early-phase psychosis as a window for prevention, suggesting that interventions targeting both cannabis use and impulsivity could reduce violence risk.
