To discourage tobacco use, federal law required all cigarette packages manufactured or sold in the United States to bear color graphics depicting the negative health consequences of smoking. The statute mandates that the new warning labels comprise the top 50 percent of the front and rear panels of cigarette packages and 20 percent of the area of each cigarette advertisement. Pursuant to this authority, the Food and Drug Administration (FDA) selected nine images that would accompany the statutorily prescribed warnings. These included images of cancerous lungs and dead bodies. Tobacco companies challenged the rules, complaining that the government had no evidence indicating that the graphic images would actually curtail tobacco use. May the FDA require that tobacco companies place graphic images on tobacco packages? Explain.
