Nicotine

I want to expand my research of the teen life project on nicotine, I want to do this because I am interesting what is nicotine what is so bad and what does it effect, and all about nicotine.
Nicotine is a very bad chemical that makes smokers addictive that smoker has been used for thousand of year. People smoke or chewed the tobacco leaves or Nicotiana tabacum.
Tobacco was first found and cultivated in the Americas, because of the discovery and colonization of North and South America, the tobacco plant was exported to Europe and to the rest of the world. Tobacco was supposed to be protective against the ravages of the plague.
Nicotine is a naturally occurring liquid alkaloid, an alkaloid is an organic compound made out of carbon, nitrogen, and sometimes oxygen. These chemicals have a lot of effects on the human body, an example that makes you addictive to the coffee is caffeine, is the same, what makes you addictive to the substance that have nicotine is that liquid alkaloid. Nicotine is make about five percent of tobacco plant. Cigarettes contain eight to twenty milligrams (mg) of nicotine, but only one milligram is actually absorbed by your body when you smoke a cigarette.

When nicotine gets to your body it gets through your skin, lungs, and mucous membranes. Nicotine moves into the small blood vessels that are near the tissues that are above, from there the nicotine travels through your bloodstream to the brain, and then it goes to the rest of your body. The most common way to get nicotine and other drugs into your bloodstream is through inhalation; by smoking it, your lungs have a lot of alveoli, which are tiny air sacs where gas exchange occurs. These alveoli provide huge surface areas that are ninety times greater than that of your skin, and this provide for access to nicotine and other compounds. When nicotine gets to your bloodstream and start to flow immediately it goes to your brain. Nicotine takes a lot of different actions throughout your body what it does to your brain is responsible for both the good feelings you get from smoking, as well as the irritability you feel if you try to quit. Nicotine doesn’t stick around your body for too long.

Here is the process by wich how nicotine gets rid of your body:

· About eighty percent of nicotine is broken down to cotinine by enzymes in your liver.
· Nicotine is metabolized in your lungs to cotinine and nicotine oxide.
· Cotinine and other metabolized can be in your urine.
· The nicotine that is left from your blood goes to your kidney and then your urine is affected.

I think that nicotine is a very interesting thing to research. I was interesting on doing this because I am curious of how does the nicotine works on your body what effects do. I hope you like my research. Know I want to expand my research on what are teens start smoking what are there resons.
