Passive Smoking

A non-smoker who breathes other people's smoke is called passive smoking. It is also called as involuntary or secondhand smoking.

Passive smoking is particularly dangerous as the passive smoker inhales -

The smoke from the burning tip of the cigarette (side stream smoke)

The smoke that has been exhaled by the smoker  (mainstream smoke)

Passive Smoking

Passive smoking consists mainly of side stream smoke. Side stream smoke contains much higher levels of many of the poisons and cancer-causing chemicals in cigarettes and is about four times more toxic than mainstream smoke. Second hand smoke comprises of up to three times more carbon monoxide, five times more cadmium and about 15 times more benzene.

The various chemicals and carcinogens in the cigarette smoke can cause smoking related diseases similar to ones acquired by actual smoking.   

Effects of passive smoking -

Effects of passive smoking depend on the exposure levels and duration of exposures. It can be immediate or late effects.

The chemicals in the cigarette smoke can cause irritation of the eyes, headache, cough, sore throat, and nausea. Studies have shown that in patients with asthma, exposure to smoke can reduce the lung function significantly and new cases of asthma can be induced in children who are exposed to cigarette smoke.

A major review by the Government-appointed Scientific Committee on Tobacco and Health (SCOTH) stated that passive smoking is the cause of lung cancer and ischemic heart disease in adult non-smokers, and the cause of respiratory disease, cot death, middle ear disease and asthmatic attacks in children. 

Passive smoking increases the risk of getting frequent lower respiratory tract infections in children. Passive smoking during childhood predisposes children to develop cancer as adults.

Exposure to passive smoking during pregnancy can lead to the birth of low birth weight babies.

Smoking can affect various parts of the body. First of all, cigarettes contain carcinogens, which are substances that cause cancer. The cancer that cigarettes are going to lead to is most very likely lung cancer. The organs that are going to be affected are for sure lungs. Lung cancer contains a process known as metastasis, which will spread the effect to other parts of the body. Hi, I am 13 years old and I really enjoy medical studies.

Why is your/the page - about the contents of a cigarette even up? It's a waste of time. People are searching for the WHOLE THING, not just some micro entry! Phooey. Thanks for the waste of time. Lay it all out! The full and complete list of ALL the dangerous poisonous stuff or at least give a link to a page that DOES have it all. At this time, your page of cigarette contents is a pretender, an anemic version of what most are looking for.

The cells of all living organisms normally divide and grow in a controlled manner. Cancer results when this control process is lost. A lump or tumour, known as the primary tumour can grow locally or spread to produce secondary tumours somewhere else in the body. This spreading process is called metastasis.
