Tobacco package warning messages are warning messages that appear on the packaging of cigarettes and other tobacco products concerning their health effects. They have been implemented in an effort to enhance the public's awareness about the harmful effects of smoking. In general, warnings used in different countries try to emphasize the same messages. Warnings for some countries are listed below. Such warnings have been required in tobacco advertising for many years, with the earliest mandatory warning labels implemented in the United States in 1966.[1] Implementing tobacco warning labels has been strongly opposed by the tobacco industry, most notably in Australia, following the implementation of plain packaging laws.
The effectiveness of tobacco warning labels has been studied extensively over the past 50 years, and research shows that they are generally effective in changing smoking attitudes and behaviors.[3][4][5] A 2009 science review determined that there is "clear evidence that tobacco package health warnings increase consumers' knowledge about the health consequences of tobacco use". The warning messages "contribute to changing consumers' attitudes towards tobacco use as well as changing consumers' behavior".[6]
Despite the demonstrated benefits of warning labels, the efficacy of fear-based messaging in reducing smoking behaviors has been subject to criticism.[7][8] A 2007 meta-analysis demonstrated that messages emphasizing the severity of threat may be less effective at changing behaviors than messages focusing on susceptibility to threat,[9] suggesting that extremely graphic warning labels are no more effective than labels that simply state the negative consequences of a behavior. Additionally, the study found that warning labels may not be effective among smokers who are not confident that they can quit, leading the authors to recommend exploring other methods of behavior modification.[10]
In many countries, a variety of warnings with graphic, disturbing images of tobacco-related harms (including hematuria and diabetes) are placed prominently on cigarette packages.
