What would the overwhelming advantage in bank deposits seem to indicate for the north?

Your answer would be, Snack food vendors were for the measure while beer vendors were against it. Marijuana; and beers are considered substitutes as they both affect the central nervous system as depressants; similarly affecting to the body; and therefore, be viewed as competitors in the market space; and reducing beer sales; as consumers pursue marijuana. However, snack foods are considered complementary as marijuana use has been shown to enhance sensory inputs; and produce "the munchies" resulting in the user purchasing snack foods thus; elevating snack food sales.

Hope that helps : )
