"Plaintiffs note that section 387p(a)(2)(B) only applies to “requirements relating to the sale” of tobacco products, unlike section 387p(a)(1), which applies to “measure[s] relating to or prohibiting the sale” of tobacco products. 21 U.S.C. § 387p(a)(2)(B), 387p(a)(1) (emphasis added). Thus, plaintiffs argue, because the ordinance prohibits the sale of flavored tobacco within 500 feet of a school, section 387p(a)(2)(B) does not apply. This argument is unpersuasive. The ordinance permits retail tobacco stores to sell flavored tobacco within 500 feet of a school; it also permits any retailer to sell flavored tobacco if located more than 500 feet from a school. Thus, the “sales restriction ... does not constitute a complete ban, as it permits the limited sale of flavored tobacco products....” U.S. Smokeless Tobacco, 708 F.3d at 435–36. Requirements relating to sale will always prohibit sale under certain circumstances, namely when the requirements for sale are not met. Because flavored tobacco products may be sold within the city if the ordinance's requirements are met, the law does not constitute a prohibition in the meaning of the FSPTCA. See id. at 436 (“[G]iven Congress's explicit decision to preserve for the states a robust role in regulating, and even banning, sales of tobacco products, we adopt a broad reading of the saving clause and a limited view of the kinds of restrictions that would constitute a ban and require us to address the permissibility of [112 F.Supp.3d 754] outright prohibitions under the saving clause.”)."
