A smoke shop’s inventory can cater to different audiences. Smoker’s World, on Carpenter Rd., sells tobacco products and cigars for the traditional crowd, e-cigarettes and accessories for on-trend nicotine fiends, and paraphernalia for marijuana users.

Owner Admon Yousif says he’s seen all kinds of customers since he opened last year, including a surprising number of elderly and sickly patients seeking accessories for medical marijuana.

Since January, when Ann Arbor banned tobacco sales to people under twenty-one, he’s also been seeing a new group of buyers: city residents aged eighteen to twenty. Just outside the city limits in Pittsfield Twp., his shop is now their closest legal source.
