Smoking is harmful to society

People start smoking for a variety of different reasons. Some think it looks cool. Others start because their family members or friends smoke.

One of the main dangers of smoking is due to Nicotine. Nicotine is found naturally in tobacco. It has no odor and no color. It is, however, both physically and psychologically addictive, and it causes those who use it to want to smoke one cigarette after another. There are other dangers of smoking as well. The tobacco smoke starts to affect the lungs. Smoking is the one of the main cause of death every year. Smoking gives a higher risk of starting a fire.

There are several solutions for the smoking. Firstly, smoker must be place away from smoke places. Secondly start doing your job
and immediately change the focus. Thirdly tell your family and friends so they can encourage you. Also you should meet your doctor and follow his advances.

There are no physical reasons to start smoking. The body doesn't need tobacco the way it needs food, water, sleep, and exercise. Smoking is a hard habit.
