Major Study Links Cannabis Use to Increased Risk of Violence and Victimization

The Relationship Between Cannabis Use and Violence

According to НВ — Техно: A comprehensive investigation conducted by King's College London has uncovered a significant association between cannabis consumption and an elevated likelihood of both committing violent acts and experiencing violence. By reviewing 63 studies involving over 265,000 participants, researchers found that cannabis users face a heightened risk of engaging in violence and being convicted of violent offenses. This connection is particularly pronounced among women, who appear to have an increased vulnerability to victimization.

Data indicates that individuals using cannabis in the general population report violent behavior at about twice the rate of non-users. Among those receiving psychiatric care, the chance of perpetrating violence rises to approximately 2.5 times higher when cannabis is used. Additionally, this group is 3 to 4 times more likely to have convictions related to violent crimes.

Impact on Victimization

Cannabis use is also linked to roughly a 50% greater risk of becoming a victim of violence. Notably, this association is stronger for women compared to men. The studies applied the World Health Organization’s definition of violence, which encompasses:

• physical violence
• sexual violence
• psychological abuse
• intimate partner violence

It is important to note that only a small number of the studies examined the frequency or amount of cannabis use, and data on criminal convictions came from a limited subset of research. Most investigations were conducted before the widespread availability of cannabis products with higher levels of active compounds. The authors suggest that daily use of these more potent forms today could be linked to stronger effects.

Given these findings, the researchers recommend that mental health professionals routinely inquire about cannabis use when assessing patients’ risk of violence. They also emphasize the need for public health messaging to address the potential connection between cannabis consumption and violent behavior. As the authors clarify,

"these results reveal an association but do not establish that cannabis directly causes violence."

This study highlights the necessity of recognizing possible risks tied to cannabis use, especially in efforts to prevent violence. Since evidence points to an increased risk for women, support programs and mental health services should incorporate these insights when working with affected individuals. Furthermore, the research underscores the importance of further scientific exploration to better understand the underlying mechanisms and to inform health and safety policies accordingly.
