"The labeling requirement and preemption provision of the Labeling Act express Congress's determination that "the prescribed federal warnings are both necessary and sufficient to achieve its purpose of informing the public of the health consequences of smoking." Altria,555 U.S. at 79, 129 S.Ct. 538. Accordingly, states may not require that additional warnings be displayed by the manufacturer. See id. "[B]oth of the Act's purposes are furthered by prohibiting States from supplementing the federally prescribed warning...." Id. In Vango Media, Inc. v. City of New York, this Court invalidated one such effort to supplement federal warnings. 34 F.3d 68 (2d Cir.1994). There, a City ordinance required that one public health message pertaining to the dangers of smoking be displayed for every four tobacco advertisements displayed on top of taxi cabs. Id. at 70. We held that this was a requirement "with respect to" advertising, and therefore preempted by the Labeling Act. Id. at 73–75. Although the ordinance did [685 F.3d 182] not impact the appearance of the advertisements themselves, it "impose[d] conditions on [the] display of cigarette advertisements." Id. at 74–75. We held that Congress intended to preempt any local law that "treads on the area of tobacco advertising, even if it does so only at the edges." Id. at 74."
