Nicotine

In the world today, Nicotine is one of the most frequently used addictive drugs. The impact it has on society is like no other. It is one of more than 4,000 chemicals found in the smoke of tobacco products such as cigarettes, cigars, and pipes. This addictive drug is the primary component in tobacco that acts on the brain.

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.

Cigarette smoking, for example, results in quick distribution of nicotine throughout the body, reaching the brain within 10 seconds. Cigar and pipe smokers on the other hand, do not inhale the smoke so the nicotine is absorbed more slowly through the mouth. When using the wet snuff it would be held either between your lips or between your gums and cheek. The dried snuff is snorted up the nose and the chewing tobacco is chewed.

Nicotine has many various effects on the body. In small doses nicotine can serves as a stimulant, entering the bloodstream and promoting the flow of adrenaline, a stimulating hormone. It also raises the blood pressure and reduces the appetite, and it may cause nausea and vomiting.

It is well documented that most smokers identify tobacco as harmful and express a desire to reduce or stop using it, and nearly 35 million of them make a serious attempt to quit. Unfortunately, 7% of those who try to quit in their own achieve more than 1 year of abstinence; most relapse within a few days of trying to quit.
