Walking into Zerona is kind of like realizing maybe you shouldn't have had that second brownie — a bit overwhelming. On the larger side for a Phoenix smoke shop, Zerona is coked to the gills with a fine selection of glassware, including from local bong-maker Rotten Pricks. The typical head shop ware here includes several brands of kratom, nitrous oxide, and CBD products. It's also a full-service tobacco shop, whether you're a home-roller, pipe user, or hookah party genie. For reasons we've never quite been able to understand, Zerona provides one-stop shopping for graffiti artists with its colorful array of spray paint and markers. If Zerona doesn't have it, you don't want it.
