What Are The Disadvantages Of Smoking?

The constituents of tobacco smoke are chemically dynamic. They can start striking and deadly changes in the body. There are more than 4,000 chemicals, which can be harmful to the smoker's body. They contain:

-- tar
-- carbon monoxide
-- nitrogen oxides
--hydrogen cyanide
--metals, ammonia

Scientists and doctors identify so much more about the ill effects of smoking now than ever before. They know smoking causes instant effects on the smoker's body. It narrows the airways. It increases the smoker's heart beat. It raises the smoker's blood pressure. The carbon monoxide in tobacco smoke removes the tissues of the smoker's body of much-needed oxygen. All of these are risky and instant effects.

There are many more severe long-term effects as well. Smoked tobacco in the types of cigarettes, pipes, and cigars causes lung cancers, emphysema, and other diseases related to respiratory system. In fact, smoking is the major reason behind ninety percent of all lung cancer cases. This disease is hardly ever seen in non-smokers. Smokers are also no less than four times more expected to build up oral and laryngeal cancer than the nonsmokers.
