A brand new research launched final week has discovered that legalizing both medical marijuana or hashish for leisure use isn’t related to a rise in site visitors fatalities that contain pedestrians. A report on the research, “An examination of relationships between cannabis legalization and fatal motor vehicle and pedestrian-involved crashes,” was printed on Friday within the journal Traffic Injury Prevention.
In a press release of the research’s aims, investigators related to the University of Minnesota defined the rationale for his or her analysis.
“While attention has been given to how legalization of recreational cannabis affects traffic crash rates, there has been limited research on how cannabis affects pedestrians involved in traffic crashes,” they wrote. “This study examined the association between cannabis legalization (medical, recreational use, and recreational sales) and fatal motor vehicle crash rates (both pedestrian-involved and total fatal crashes).”
To conduct the research, the crew of researchers investigated the affiliation between legal guidelines legalizing hashish and deadly motorcar crash charges, together with each pedestrian-involved and deadly automobile collisions. Motor automobile accidents in three states with authorized hashish—Oregon, Washington, and Colorado—have been in comparison with the tendencies in 5 management states. The investigators have been unable to determine any improve in deadly motorcar accidents that may very well be attributed to the adoption of insurance policies that legalized hashish.
“We found no significant differences in pedestrian-involved fatal motor vehicle crashes between legalized cannabis states and control states following medical or recreational cannabis legalization,” the researchers wrote within the outcomes of the research.
More Than 25 Years Of Crash Data Analyzed
The investigators used crash knowledge from the Fatality Analysis Reporting System (FARS) to calculate month-to-month charges of deadly motorcar crashes and deadly pedestrian-involved crashes per 100,000 folks from 1991 to 2018. Changes in month-to-month crash charges within the three states that had legalized hashish have been in comparison with matched management states utilizing segmented regression with autoregressive phrases.
Both Washington and Oregon noticed quick decreases in all deadly crashes following the legalization of hashish for medicinal functions. Colorado confirmed a rise in development for all deadly crashes after hashish was legalized to be used by adults and the start of leisure gross sales in 2014.
“Overall, these findings do not suggest an elevated risk of motor vehicle crashes associated with cannabis legalization, nor do they suggest an increased risk of pedestrian-involved motor vehicle crashes,” the authors of the research wrote of their conclusion.
In a press launch in regards to the research, the National Organization for the Reform of Marijuana Laws (NORML) famous that the outcomes of the analysis are in step with these of comparable research. In a study printed final yr, a crew of investigators from the University of California at Irvine decided that the legalization of medical marijuana in California was related to a sustained decline in site visitors fatalities. And in 2016, investigators with Columbia University in New York and the University of California at Davis found that the legalization of medical marijuana is related to a discount of site visitors fatalities amongst youthful drivers.
