Summary: Researchers assessed the time trends in alcohol and marijuana detected in homicide victims and found that the prevalence of marijuana almost doubled, increasing from 22 percent in 2004 to 42 percent in 2016. Alternately, the prevalence of alcohol declined slightly from 40 percent in 2004 to 35 percent in 2016.

“Our findings are of public health significance because previous research has established marijuana use as an important risk factor for homicide victimization. The impact of increased permissibility and availability of marijuana on violence and injuries needs to be closely monitored and rigorously studied,” said Dr. Li.
