Does marijuana use raise the risk of violence and mental illness?
Core argument: A study found young individuals with mood disorders who are addicted to marijuana are 3.2 times more likely to commit self-harm and to die of homicide, often after initiating violence themselves.
The increasing legalization of cannabis across 19 states has coincided with a rise in mental health issues and violent behavior, particularly among young users. A study found that young individuals with mood disorders who are addicted to marijuana are 3.2 times more likely to commit self-harm and die of homicide, often after initiating violence. A meta-analysis revealed that the risk of perpetrating violence is over twice as high for young adults using marijuana. The potency of cannabis has increased significantly, with THC levels now up to 20 times higher than in the 1960s, leading to higher addiction rates and associated psychological issues. In California, cannabis-related emergency-room visits rose 53% post-legalization. Additionally, early marijuana use is linked to a significant increase in schizophrenia risk, with cases in Denmark rising three- to fourfold as potency increased by 200%. These trends suggest a need for policymakers to reassess the implications of cannabis legalization on public health and safety.

I don’t fully understand the numbers and need you to look at the online database and call them. On pages 261, 276, 345 and 485 (France, Germany, Italy and Sweden) they have charts that look like this:
Ed Comment:Nowhere could I find an equivalent chart for the US except for pretax (i.e. before all their calculations)—Table III in the main report. I tried to calculate post tax US amounts myself but the I couldn’t reconcile the numbers. Perhaps they have a chart I couldn’t find. or we can find it in the online database. I fear they didn’t presenting one because the numbers aren’t as comparable as they want the reader to believe. (Post tax BTW is after subtracting taxes and adding back government services. The study says the poor in Europe are heavily taxed but receive more government services.) They do make post tax comparison in charts in the appendix see below
