Global study reveals low awareness of smoking's cardiovascular risks

A study involving over 240,000 smokers across 46 countries has revealed a significant gap in public awareness regarding the cardiovascular risks of tobacco use. While more than 90% of respondents recognized that smoking can cause lung cancer, only approximately 80% identified heart disease as a consequence, and even fewer were aware of the risks of stroke or the dangers of secondhand smoke.

Janet Chung-Hall, a researcher with the International Tobacco Control Policy Evaluation Project (ITC Project) at the University of Waterloo and the study's lead author, described the lack of knowledge regarding these major health effects as “extremely worrying.” The findings raise questions about the effectiveness of long-standing health warnings, especially since smoking is linked to more than 2 million cardiovascular deaths globally each year.
