This summer, the U.S. Food and Drug Admin­is­tra­tion unveiled graphic new cig­a­rette warning labels that will be required to appear on pack­ages starting next year. We talked to law pro­fessor Richard Day­nard, the pres­i­dent of the School of Law’s Public Health Advo­cacy Insti­tute and chair of its Tobacco Prod­ucts Lia­bility Project, about the effec­tive­ness of warning labels and a law­suit chal­lenging the new labels’ legality.

Will the new warning labels be an effec­tive smoking deter­rent in the United States? How do they com­pare to past efforts to warn people about the dan­gers of smoking?

They are a dra­matic improve­ment over the cur­rent labels, which studies show are not actu­ally read by most smokers. The cur­rent warn­ings, even if read, make only cog­ni­tive state­ments, while the new warn­ings also make emo­tional state­ments. No one who thinks he or she can change con­sumer behavior by making only cog­ni­tive state­ments would last five min­utes on Madison Avenue. It has been dif­fi­cult to prove pre­cisely how much deter­rent effect large graphic warn­ings have because they are gen­er­ally intro­duced along with other tobacco con­trol mea­sures, such as tax increases. But we know that when they appeared in Canada, some mer­chants devised sleeves to cover up the package images, an acknowl­edge­ment that they “turned off” consumers.

Other coun­tries such as Canada and Uruguay have used graphic, even grisly, images for years. Why has the United States been slow to follow suit?

The tobacco industry, which used to have effec­tive con­trol of the Con­gress on tobacco issues, obtained leg­is­la­tion in 1965 that said that only Con­gress could dic­tate package warn­ings. Need­less to say, the warn­ings imposed by a tame Con­gress were small, solely cog­ni­tive and rarely noticed by smokers. Industry lob­by­ists thwarted efforts to change this as recently as 2008, when White House offi­cials under George W. Bush sug­gested he might veto leg­is­la­tion giving the Food and Drug Admin­is­tra­tion both authority and a man­date to design and require large pic­to­rial warn­ings. But rev­e­la­tions from internal tobacco industry doc­u­ments made public as a result of state tobacco lit­i­ga­tion in the 1990s reduced the industry’s polit­ical influ­ence, as did the gradual but steady decline in the pro­por­tion of Amer­i­cans who smoke and the diver­si­fi­ca­tion of the indus­trial base in Southern states. Thus Con­gress finally passed the Family Smoking Pre­ven­tion and Tobacco Con­trol Act in 2009, and Pres­i­dent Obama hap­pily signed it.

Major tobacco com­pa­nies have filed a fed­eral law­suit about the legality of the new labels. What is the likely out­come of such a suit?

It’s hard to see even the cur­rent Supreme Court — pro-​​business and heed­less of prece­dent though they are — taking this law­suit seri­ously. There is no ques­tion the warn­ings are now autho­rized by statute, so the only pos­sible issue is whether they inter­fere with the tobacco industry’s First Amend­ment rights. But Con­gress has for more than 70 years lim­ited stock issuers pro­mo­tions of their offer­ings to a plain-​​vanilla, highly reg­u­lated prospectus, and Drano has, as long as I can remember, had a man­dated skull and cross­bones on it. Indeed, most deadly and addic­tive drugs are banned outright.
