In the world today, Nicotine is one of the most frequently used addictive drugs. The impact it has on society is like no other.

Tobacco can be found two ways, it can be dried brown leaves of various sizes or it can be a grown form of tobacco. When extracted from the leaves, nicotine is colorless, but quickly turns brown when exposed to air. It then becomes a poisonous, pale yellow, oily liquid with a pungent odor and acrid taste. The amount of nicotine contained in tobacco leaves ranges from 2% to 7%. There are four ways in which you can use tobacco. They are cigarette smoke, dry or wet snuff, and chewing tobacco. The cigarette smoke is inhaled through the mouth. Most cigarettes in the US contain 10 milligrams or more of the nicotine. Since most of the nicotine is destroyed by the heat of burning the actual concentration of nicotine in smoke is low. So, when inhaling the smoke you actually only take in 1 to 2 mg of nicotine per cigarette. Nicotine is absorbed through the skin, lining of the mouth and nose, or by inhalation in the lungs.

Cigarette addiction is responsible for over four million deaths every year. The question most people ask is why don’t people just put down their cigarettes? Well, the answer to that often asked question is nicotine. Nicotine is a neurotransmitter that targets certain receptors in the brain. It is a chemical messenger that induces feelings of pleasure.

During the time period 1450 to 1750, the world went through major change and development. Nomadic power declined, and European Kingdoms became world powers. A world trade network was set up as contact amongst nations increased immensely. A population boom occurred throughout the world. Many civilizations that were once isolated were brought into the world economy. The Americas unknown until Christopher Columbus’ voyage in 1492 became a major part of the world economy as many European nations colonized much of the land. Large sea trade arose during this time period first by the Portuguese and Spanish and later by the English, French and Dutch. As European countries began exploring the Americas, an exchange of crops, animals, raw materials, diseases and new ideas were exchanged between the Americas and the rest of the world. This is known as the Columbian Exchange. One major component of the Columbian Exchange was the discovery of tobacco. Tobacco was first discovered in the Americas and became as cash crop. It was imported back to Europe, where it became vastly popular. As many middle class Europeans people began smoking, the demand for more tobacco from the Americas increased; colonies were set up to produce tobacco. With the demand for tobacco so high, labor was needed to farm the crop causing slaves to be imported.
