“most likely due” is not exactly a fact.
I’m thinking of a number between 1 and 10. What is the number?
It's supported by the linked article: "Finally, the relationship between MMLs and more direct measures of alcohol consumption is examined. Using data from the Behavioral Risk Factor Surveillance System (BRFSS), we find that MMLs are associated with decreases in the number of drinks consumed,especially among 20- through 29-year-olds, providing additional evidence that alcohol is the mechanism by which traffic fatalities are reduced. Using data from the Beer Institute, we find that beer sales fall after a MML comes into effect, suggesting that marijuana substitutes for beer, the most popular alcoholic beverage among young adults."
