News release: “Exposure to tobacco smoke – even occasional smoking or secondhand smoke – causes immediate damage to your body that can lead to serious illness or death, according to a report released today by U.S. Surgeon General Regina M. Benjamin. The comprehensive scientific report – Benjamin’s first Surgeon General’s report and the 30th tobacco-related Surgeon General’s report issued since 1964 – describes specific pathways by which tobacco smoke damages the human body and leads to disease and death. The report, How Tobacco Smoke Causes Disease: The Biology and Behavioral Basis for Smoking-Attributable Disease, finds that cellular damage and tissue inflammation from tobacco smoke are immediate, and that repeated exposure weakens the body’s ability to heal the damage…The report also explains why it is so difficult to quit smoking. According to the research, cigarettes are designed for addiction. The design and contents of current tobacco products make them more attractive and addictive than ever before. Today’s cigarettes deliver nicotine more quickly and efficiently than cigarettes of many years ago. Tobacco smoke contains a deadly mixture of more than 7,000 chemicals and compounds, of which hundreds are toxic and at least 70 cause cancer. Every exposure to these cancer-causing chemicals could damage DNA in a way that leads to cancer. Exposure to smoke also decreases the benefits of chemotherapy and other cancer treatments. Smoking causes more than 85% of lung cancers and can cause cancer almost anywhere in the body. One in three cancer deaths in the U.S. is tobacco-related.”
