Light Smoking Linked to Decades of Heart Damage

Breaking News: Smoking Just a Few Cigarettes a Day Can Damage Your Heart for Decades A recent review of nearly two dozen long-term studies has revealed that even very light smokers face a significantly higher risk of heart failure and early death. According to the research, published in PLOS, people who smoke only a couple of cigarettes a day still face a much higher chance of heart disease and early death than those who have never smoked. This elevated risk remains for years after quitting. The review, conducted by researchers and experts, analyzed data from 22 long-term studies on smoking and cardiovascular health. The studies, which spanned several decades, found that even very light smoking sharply increases the likelihood of heart failure and death. The elevated risk can persist for many years after quitting, highlighting the importance of quitting entirely, especially at younger ages. Michael Blaha, a leading expert in cardiovascular health, emphasized the urgent need for smokers to quit. "Quitting leads to major health improvements, but some risk remains for decades," he said. "The safest approach is quitting entirely, especially at younger ages." The research findings have significant implications for public health policy and smoking cessation programs. Health organizations and governments must now reassess their strategies to address the risks associated with even light smoking. In the past, it was believed that smoking a few cigarettes a day posed a relatively low risk to cardiovascular health. However, this new research challenges that assumption, highlighting the need for a more nuanced understanding of the risks associated with smoking. As the scientific community continues to study the effects of smoking, one thing is clear: quitting is the safest approach to reducing the risk of heart disease and early death. For those who are struggling to quit, there are numerous resources available, including counseling services and nicotine replacement therapy. The research was published in PLOS on November 22, 2025. As the news spreads, health experts are urging smokers to take immediate action to protect their heart health.
