Follow the dollar, there you will find the truth! Ama$on stands to make billions on the sale of growing related products. Just another emerging market for them to corner and profit from. These companies write their own drug policies, can enforce, or not enforce them. It has nothing to do with opening up "employment opportunities". Those type of jobs draw a blue collar demographic( race has absolutely nothing to do with it) which is more inclined to partake in weed. Even if you look at it from an insurance company perspective, these companies are large enough to tell them to F off and there will be a line of other providers to gladly take their money.
