When I smoked the "going out night" was buy three packs of smokes and see what the night had to offer.Did not smoke every day so opened packs got discarded as trash when the night was done.Was wondering how efficient everyone else thinks a bottle cap is?Have never worried about the stink of vape though it does make a room smell like candy, but feel "greener" less wasteful in the fact that the product that is purchased gets used.We all can buy lots of juice , me included, that seems wasteful searching for the holy grail of flavor and dump it because its cost pennies on the dollar compared to smokes.My question , guess, is vaping is less wasteful any thoughts?
