The nation’s largest grocery store chain is joining a growing list of national retailers with its plan to begin selling C-B-D products. Kroger owns Pick ‘N Save and Metro Market stores in Wisconsin. It plans to sell C-B-D creams, balms and oils in 17 states. Derived from hemp, C-B-D is legal thanks to the 2018 Farm Bill. Customers are curious about the possible benefits of the product, even though there is hardly any scientific evidence to confirm the claims.
