Smoke shops have NOT changed all that much from the 70s, at least not in California, what with medical marijuana "pharmacies" cropping - hehehehehe - up all over. In the same place where I can buy stale PopTarts and my brand, flavor and size of cigarette (Virginia Slims, "Silver" or ultra-light menthol, 120s) one can buy hookahs, bongs, pipes, clips, papers, rollers, screens, oh, just anything you need to enjoy your loose leaf tobacco or legal marijuana. Some of the blown glass articles are absolutely gorgeous.
The little mini-mart, gas staion within walking distance of my house has a surprising array of hard liquor brands in addition to juat about any kind of beer and a few, select wine labels. (Big wine country.) plus all the Slim Jims you could possibly want.
TP, paper plates and plastic utensils, soda, cans o' soup, bags o' rice, marshmallows.... An eclectic mix. But very limited cigarette selection. Lots of chaw, though!
