From the very first paragraph of the article you linked: "Research firm Cowen & Company analyzed the state of the beer industry in Colorado, Oregon and Washington—states where both recreational weed is legal and craft beer has become popular". And: "MilllerCoors have seen the largest drops. Sales volume of premium brews like Coors Light and Bud Light dipped by 4.4%, while economy brews—the regular forms of mainstream beers like Budweiser or Coors—dipped by 2.4%." Sales of craft beers go up, sales of draft beers go down. I'm not putting all of that on weed. I really don't like how all the sources of articles on the impact and results of weed legalization link to... other weed legalization articles. P.S. A large amount of this "information" is just normal if well disguised click-bait. Please, please, please, link me to hard data if you want to change my mind. I will read every sentence of it! P.S.S. Also craft beer has EXPLODED in places like Portland and it seems like a natural outcome that, because craft beer is much more expensive, that people buy less of it and enjoy it as more of a social delicacy then a weekend event.
