The Canadian labels led to a 2.9 to 4.7 percentage point drop in smoking rates — which would mean 5.3 to 8.6 million fewer smokers in the U.S. if the same result were obtained. The findings are published online in the journal Tobacco Control.
The researchers used statistical methods to compare smoking rates in the U.S. and Canada for a nine-year period before and after the graphic warning labels were introduced in Canada. The price of cigarettes were factored into the analyses.
The study found the “regulatory impact analysis” used by the U.S. Food and Drug Administration to gauge the effectiveness of Canada’s graphic warning labels to be inaccurate. The FDA had estimated only a 0.088 percentage point reduction in smoking rates after graphic warning labels were mandated in Canada.
Jidong Huang, research specialist at UIC’s Institute for Health Research and Policy and lead author of the new study, said when he and his collaborators corrected the FDA’s methodological flaws and took into account the purchase prices paid by smokers, they found that graphic warning labels reduce cigarette-smoking prevalence at much higher rates.
Graphic warning labels on cigarette packages have been implemented in more than 40 countries, but not in the U.S.
In 2009, the Family Smoking Prevention and Tobacco Control Act gave the FDA authority to regulate the manufacture, distribution and marketing of tobacco products, including requiring prominent warning labels for cigarettes and smokeless tobacco products. However, the tobacco industry challenged the FDA’s requirement for graphic warning labels, and a U.S. Court of Appeals ruled that the federal agency lacked evidence that graphic warning images would reduce the number of Americans who smoke. Studies had shown that such labels increase knowledge of the harmful effects of tobacco products, motivate smokers to attempt quitting, and decrease relapse rates among smokers who have quit, but not whether they reduce overall smoking rates.
The UIC and University of Waterloo researchers hope the new study will provide support for a revised FDA proposal to require graphic warnings.
The FDA should “adopt a standard methodology in doing their regulatory impact analysis that is statistically sound and validated by social scientists,” said Huang. The “very rudimentary analysis” methods currently used by the FDA will cause problems in future proposals and regulations for new and emerging tobacco products, he said.
Geoffrey Fong, professor of psychology at the University of Waterloo, said the new study “adds to the strong and growing number of studies showing the powerful positive impact of graphic warnings on reducing smoking rates.”
Fong and Frank Chaloupka, distinguished professor of economics and director of the Health Policy Center at UIC’s Institute for Health Research and Policy, are co-investigators.

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
