Background

Tobacco is a plant that grows natively in North and South America. The seed of a tobacco plant is very small. It is believed that Tobacco began growing in the Americas about 6,000 B.C. As early as 1 B.C., American Indians began using tobacco in many different ways, such as in religious and medicinalpractices. Tobacco was believed to be a cure-all, and was used to heal wounds, as well as a pain killer. Chewing tobacco was believed to relieve the pain of a toothache.

Christopher Columbus was offered dried tobacco leaves as a gift from the American Indians that he encountered. Soon after, sailors brought tobacco back to Europe, and the plant was being grown all over Europe. The major reason fortobacco's growing popularity in Europe was its supposed healing properties.

During the 1980's there were many lawsuits filed against the tobacco industry because of the harmful effects of its products. Smoking becomes politically incorrect, with more public places forbidding smoking.

After the leaves are dried they are treated with around 4000 different chemicals before being made into cigarettes. Many of these chemicals cause cancer, and tobacco smoke itself is carcinogenic.

Tar is the name given to the yellow-brown substance that stains smokers' teeth, fingers and lungs.It is made up of many different chemical particles and is the main cause of throat and lung cancer in smokers. All cigarettes contain tar.
