Taking on tobacco was no small task at mid-century, when more than half of men and a third of women smoked. In 1956, the AHA’s first scientific statement on smoking concluded that more evidence was needed to link it to heart disease. But as evidence grew, so did our role. Even before the landmark Surgeon General’s report of 1964, we called for a public campaign against smoking.

By 1971, we said cigarette smoking “contributed significantly” to coronary heart disease, and in 1977, we declared smoking to be the most preventable cause of heart disease.

In the 1980s, with significant support from the AHA, new laws required stronger warning labels for cigarettes and banned smoking on airplanes. Today, we’re working to understand the risks of e-cigarettes and vaping while fighting to keep teens and others from starting.
