Scientific research has increasingly focused on the neurological and social implications of cannabis use. A study from Northwestern University identified a specific neural pathway in the central amygdala involving somatostatin (SOM) neurons. Researchers found that cannabinoids can weaken the brain’s natural inhibitory signals, making fear-related cells easier to excite and potentially triggering anxiety and panic responses.

Building on neurological findings, a meta-analysis of 63 studies involving over 265,000 participants published in Psychological Medicine identified a correlation between cannabis use and an increased risk of violence. The data suggests users are statistically more likely to both commit violent acts and become victims of violence, particularly among women. Researchers noted that this is a correlation rather than a proven causal link, suggesting users may be more frequently exposed to high-risk or criminal environments.
