1. Nicotine
The average cigarette contains from 1 to 16 grams of nicotine.  When inhaled, nicotine enters the bloodstream, reaching the brain in less than 10 seconds.  In less than a minute, nicotine spreads throughout the entire body.
Since nicotine is a stimulate, it raised blood pressure and increases the heart rate,

2. Poisonous Substances in Tobacco Smoke Tar & Carbon Monoxide
Tobacco is an addictive and toxic drug. It’s a carcinogen. Tobacco Smoke contains Tar and Carbon Monoxide.

3. TAR
The tar damages a smoker’s respiratory system by paralyzing and destroying cilia.
Tar destroys the alveoli which absorbs oxygen and rids the body of carbon dioxide.
Smokers are susceptible to bronchitis, pneumonia, emphysema, heart disease, and cancer.

4. Carbon Monoxide Its is absorbed more easily than oxygen.
It increases the risk of high blood pressure, hardening of the arteries, and other circulatory problems.

5. Pipes, Cigars, Dip, and Chew.
Smokeless Tobacco
Pipes, Cigars, Dip, and Chew.
Cigars contain significantly more nicotine and produce more tar and carbon monoxide than cigarettes (20 cigarettes).
