Smoking is a known risk factor for various long-term health conditions and premature deaths. Now, a recent study reveals that by lowering the prevalence of smoking from current levels to just 5% everywhere, there will be a significant boost in life expectancy and prevent millions of premature deaths worldwide by 2050.
Smoking has claimed more than 175 million lives and resulted in nearly 4·30 billion years of life lost (premature deaths) from 1990 to 2021.
