Smoking-related deaths represent 80% of lung cancer mortalities and 30% of all cancer deaths in the United States. Tobacco use also raises the risk of many other health conditions, including multiple types of cancer, respiratory illness, heart disease, heart attack, stroke, low bone density, type 2 diabetes, cataracts, and macular degeneration. Research has consistently shown that smoking cessation is paramount to lung health, and smokers who quit are more likely to live a healthier and longer life while greatly decreasing their risk of lung cancer.
