When you walk through the touristy Pike-Pine corridor in downtown Seattle, it’s hard to miss the smoke shops that pervade the area. On the ground level window display of Smoke Plus, on the busy intersection of Pike and First Ave., there are boxes of cigars, glass pipes of various colors and sizes, and a lineup of grandiose hookah pipes with long coils shoved against each other. A sweet scent permeates the shop’s perimeter that leads down to the basement.
