Smoking harms almost every organ of the body and diminishes a person’s overall health. The chances of smokers being affected by cancer are very high.

Several studies have shown that the various carcinogens in the cigarette smoke cause cancer. Cancers are most likely to occur in organs like lungs and oral cavity, which come into direct, contact with smoke.

Cigarette smoke contains about 4,000 chemical agents, out of which 70 substances are carcinogenic. Some of these harmful substances are - carbon monoxide, tar, arsenic, cyanide, benzene, formaldehyde, methanol, acetylene, ammonia, lead etc.

When the carcinogens in cigarette smoke are absorbed and spread through the human body, smoking causes cancer at various distant sites. Smoking causes many types of cancer, including cancers of the lung, esophagus, larynx, mouth, throat, kidney, liver, bladder, pancreas, stomach, cervix, bowel and also acute myeloid leukemia.

The risk of developing cancer is related to:

  • Number of cigarettes smoked

  • Age at which smoking is started
  • The type of cigarettes smoked

Types of smoking:

  • Active smoking - Active smoking is the intentional inhalation of smoke using cigarettes and cigars.
  • Passive smoking - Passive smoking is when a non-smoker breathes other people's smoke. It is also called as involuntary or secondhand smoking.

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.
