/EIN News/ — OTTAWA, Dec. 8, 2022 (GLOBE NEWSWIRE) — A new report from the Canadian Institute of Actuaries (CIA) and the Casualty Actuarial Society (CAS) analyzes the impact of cannabis legalization on vehicle accident experience. Affects in Canada and the United States. The study did not find any statistically significant effect of decriminalization on car crash mortality, frequency of insurance claims, or average cost per claim, especially over the long term.
Assessing the Effect of Marijuana Legalization on Vehicle Accident Experience The trend and seasonality of traffic accidents in Canada did not change significantly after the legal status change, according to insurance statistics. Likewise, the estimated statewide impact of decriminalization in the United States does not reveal any consistent, significant results to support the conclusion that decriminalization leads to an increase in road accidents or deaths.
Temporal patterns of human activity (eg, yearly, weekly, and daily cycles) and severe weather were more predictive of vehicle accident experience than marijuana legalization.
The study overcomes the limitations and shortcomings of earlier research on the effects of cannabis decriminalization by incorporating a novel data-driven approach.
“The methods used in this study include improved statistical models, machine learning and other data science techniques. These models use high-resolution weather data to explain the influence of weather factors,” said report author Dr. Vyacheslav Lyubchich.
