Surgeon General -Report:How Tobacco Smoke Causes Disease

The following is a summary provided by the Office of the Surgeon General of their recent report on "How Tobacco Smoke Causes Disease". A copy of the report or this summary may be found on the Office of the Surgeon General website. www.hhs.gov

THERE IS NO SAFE LEVEL OF EXPOSURE TO TOBACCO SMOKE. ANY EXPOSURE TO TOBACCO SMOKE - EVEN AN OCCASIONAL CIGARETTE OR EXPOSURE TO SECONDHAND SMOKE - IS HARMFUL.

* You don't have to ba a heavy smoker or a long-time smoker to get a smoking-related disase or have a heart attack or asthma attack that is triggered by tobacco smoke.

* Low levels of smoke exposure, including exposures to secondhand tobacco smoke, lead to a rapid and sharp increase in dysfunction and inflammation of the lining of the blood vessels, which are implicated in heart attacks and stroke.

* Cigarette smoke contains more than 7,000 chemicals and compounds. Hundreds are toxic and more than 70 cause cancer. Tobacco msoke itself is a know human circinogen.

* Chemicals in tobacco smoke interfere with the functioning of fallopian tubes, increasing risk for adverse preganancy outcomes such as ectopic pregnancy, miscarriage, and low birth weight. They also damage the DNA in sperm which might reduce fertility and harm fetal develpment.

DAMAGE FROM TOBACCO SMOKE IS IMMEDIATE.

* The chemicals in tobacco smoke reach your lungs quickly every time you inhale. Your blood then carries the toxicants to every organ in your body.

* The chemicals and toxicants in tobacco smoke damage DNA, which can lead to cancer. Nearly one-third of all cancer deaths every year are directly linkd to smoking. Smoking causes about 85% of lung cancers in the US.

* Exposure to tobacco smoke quickly damages blood vessels throughout the body and makes blood more likely to clot. This damage can cause heart attacks, strokes, and even sudden death.

*The chemicals in tobacco smoke inflame the dlicate lining of the lungs and can cause permanent damage that reduces the ability of the lungs to exchange air efficiently and leads to chronic obstructive pulmonary disease (COPD) which includes emphysema and chronic bronchitis.

SMOKING LONGER MEANS MORE DAMAGE.

*Both the risk and the severity of many diseases caused by smoking are directly related to how long the smoker has smoked and the number of cigarettes smoked per day.

* Chemicals in tobacco smoke cause inflammation and cell damage, and can weaken the immune system. The body makes white blood cells to respond to injuries, infections, and cancers. White blood cell counts stay high while smoking which can lead to disease in almost any part of the body.

* Smoking can cause cancer and weaken your bodys ability to fight cancer. With any cancer - even those not related to tobacco use - smoking can decrease the benefits of chemotherapy and other cancer treatments. Exposure to tobacco smoke can help tumors grow.

* The chemicals in tobacco smoke complicate the regulation of blood sugar levels, exacerbating the health issues resulting from diabetes. Smokers with diabetes have a higher risk of heart and kidney disease, amputation, eye disease causing blindness, nerve damage and poor circulation.

CIGARETTES ARE DESIGNED FOR ADDICTION

*The design and contents of toacco products make them more attrative and addictive than ever before. Cigarettes today deliver nicotine more quickly from the lungs to the heart and brain.

* While nicotine is the key chemical compound that causes and sustains the powerful addicting effect of cigarettes, other ingredients and design features make them even more attractive and more addictive.

*The powerful addicting elements of toacco products affect multiple types of nicotine receptors in the brain.

*Evidence suggest that psychosocial, biologic, and genetic factors may also play a role in nicotine addiction.

*Adolescents' bodies are more sensitive to nicotine, and adolescents are more easily addicted than adults. This helps exxplain why about 1,000 teenagers become daily smokers every day.

THERE IS NO SAFE CIGARETTE.

*The evidence indicates that changing cigarette designsover the last five decades, including filtered, low-tar and "light" variations, have NOT reduced overall disease risk among smokers and may have hindered prevention and cessation efforts.

*The overall health of the public could be harmed of the introduction of novel tobacco products encourages tobacco use among people who would otherwise be unlikely to use tobacco product or delays cessation among persons who would otherwise quit using tobacco altogether.

THE ONLY PROVEN STRATEGY FOR REDUCING THE RISK OF TOBACCO-RELATED DISEASE AND DEATH IS TO NEVER SMOKE, AND IF YOU DO SMOKE TO QUIT.

*Quitting at any age and at any time is beneficial. It's never too late to quit, but the sooner the better.

*Quitting gives your body a chance to heal the damage caused by smoking.

*When smokers quit, the risk for a heart attack drops sharply after just 1 year/ stroke risk can fall to about the same as a nonsmoker's after 2-5 year; risks for cancer of the mouth, throat, esophagus, and bladder are cut in half after 5 years and the risk for dying of lung cancer drops by half after 10 years.

* Smokers often make several attempts before they are able to quit, but new strategies for cessation, including nicotine replacement and non-nicotine medications, can make it easier.

* Talk to your doctor or call the Quit line and get started on a quit plan today.
