addiction to smoking tobacco products shall be considered an epidemic. It kills more than 5 million people each year worldwide. Of that 5 million people, 70% percent is considered low or middle income countries and the gap between high income countries is expected to be higher in the next decade with a death toll rises to an estimated 8 million people by 2030. It is still considered a preventable death, and prevent the leading cause of deaths in the world.

health issues around smoking comes from inhaling smoke generated by burning tobacco, which in turn release more chemicals into the body, and the air around the smoker. smoker is not the only person who is smoking tobacco, but the people around them are exposed to "second hand" smoke, as well. Second hand smoke is responsible for the premature death of 600 000 people annually.

This was the cause of sudden death in infants, and pregnant women who smoke usually give birth to low weight babies. Of 600 000 deaths caused by second hand smoke, 31% of them are children who have been exposed. Studies have also shown that children exposed to second hand smoke are also more likely to become smokers.

Of course, the smoker carries a higher risk with a far greater exposure to chemicals produced by burning tobacco. Only after 15-20 years of quitting smoking is not a smoker your risk of heart and lung diseases are becoming closer to that of a non-smoker. Smoking is the leading cause of lung cancer, emphysema and chronic bronchitis, all of which can lead to death. cardiovascular system in the body is affected by decreased size of blood vessels and the ability to carry oxygen in red blood cells decreases. This means that the heart must work harder to get the necessary levels of oxygen to the rest of the body, but it takes more strain because there is not enough oxygen alone.

of cancer that affects smokers generally affects the lungs, throat, mouth, nose and sinus passages, as well as other forms, such as the pancreas and bladder. It is estimated that one third of cancer deaths each year caused by smoking. carcinogens absorbed into the body through smoking to prevent the body's ability to control cell growth, which in turn causes cancer cells to grow out of control.

Out of these life-threatening problems associated with smoking, a smoker is more susceptible to colds, flu and pneumonia. They also often use cigarettes as a meal replacement, because it suppresses the appetite, resulting in a further risk of disease as the body does not absorb enough of its necessary nutrients. activity level of smokers was significantly lower than those for non-smokers and they can not keep up in the same sports environment for things such as shortness of breath.

All in all, there is no benefit to smoking, but plenty of flaws, even if only as an occasional smoker. The reason is that tobacco smoke is harmful poison and the body is not equipped to handle it.
