According to the report of the World Health Organization (WHO), tobacco kills more than 8 million people globally every year. Of which, more than 7 million people die from direct tobacco use and about 1.2 million people die even though they do not smoke but are exposed to secondhand smoke.

Smoking is a risk factor for respiratory infections and increases the severity of respiratory diseases. A review by a panel of public health experts convened by WHO on April 29, 2020 found that smokers are at a higher risk of serious health complications from COVID-19 than smokers. non-smokers.
There are more than 5,000 chemical components found in cigarette smoke and hundreds of them are harmful to human health. Some of the main substances found in cigarette smoke are:
1,3-Butadiene is a chemical used to make rubber. It is considered a carcinogenic chemical and may cause some blood cancers. Arsenic is used to preserve wood. Certain arsenic compounds have been linked to lung, skin, liver, and bladder cancers. Benzene is used to make other chemicals. It can cause cancer, especially leukemia in humans. Cadmium is the metal used to make batteries. Cadmium and cadmium compounds can cause lung cancer and have been linked to kidney and prostate cancer. Chromium VI is used to make alloy metals, paints and dyes. Chromium VI compounds cause lung cancer and have been linked to cancers of the nose and sinuses. Formaldehyde is used to manufacture other chemicals and plastics. It is also used as a preservative. Formaldehyde causes leukemia and cancer in respiratory tissues. Polonium-210 is a radioactive element that has been shown to cause cancer in animals. Tar is made from certain chemicals found in tobacco smoke.

Smoking can damage a baby's lung and brain development. Smoking increases the risk of having a baby with birth defects. Babies of mothers who smoke during pregnancy and infants exposed to secondhand smoke after birth are at increased risk of sudden infant death syndrome.

The answer is NO
Light cigarettes are no safer than regular cigarettes. E-cigarettes cause 15 times more cancer than cigarettes. Cigarettes labeled "additive-free" or "natural" have the same cancer-causing ingredients as regular cigarettes. Filtered cigarettes do not block all the harmful chemicals in cigarettes. Pipe tobacco is as toxic as cigarettes. All types of tobacco are harmful, and any exposure to secondhand smoke can damage the body. There is no safe level of exposure to secondhand smoke, and there is no such thing as safe tobacco.

Smokers are not the only ones affected by secondhand smoke. Tobacco smoke and vapors are a serious health hazard to non-smokers, especially children. Non-smokers with high blood pressure or high blood cholesterol have an even higher risk of heart disease from breathing secondhand smoke. Secondhand smoke contributes to thousands of premature deaths from heart disease and lung cancer. Studies show that the risk of heart disease in people who breathe secondhand smoke at home or work is about 25-30% higher. Passive smoking also promotes disease. Children born to smokers have a higher risk of respiratory infections than children born to non-smokers.
