Nicotine is the chemical inside tobacco that makes it so addicting. It is one of the most addicting substances known to man.Like acetylcholine, nicotine leads to a burst of receptor activity. However, unlike acetylcholine, nicotine is not regulated by your body. While neurons typically release small amounts of acetylcholine in a regulated manner, nicotine activates cholinergic neurons (which mainly use acetylcholine to communicate to other neurons) in many different regions throughout your brain simultaneously. http://science.howstuffworks.com/nicotine4.htm Nicotine withdrawal symptoms include headache, anxiety, nausea and a craving for more tobacco.. Nicotine creates a chemical dependency, so that the body develops a need for a certain level of nicotine at all times. http://www.quitsmokingsupport.com/withdrawal1.htm The study found that 70 percent of current adult smokers would like to quit, but only 41 percent had quit smoking for even as little as a day. http://articles.cnn.com/2002-07-25/health/cdc.smoking_1_black-smokers-smoking-cessation-cdc?_s=PM:HEALTH
Affects of smoking
1. Coughing: Smokers coughing that is. After a not predetermined time of being a smoker, you will begin to experience smokers cough, because your body uses this as a way to try and get rid of the toxins you inhale while smoking. 2. Yellow teeth: many smokers when they realize the state of their smile, that have gone from bright white to almost yellow stop smiling all that much, or try to hide their teeth while smiling. 3. Trouble with blood circulation: After contaminating your blood for a period of time with the smoke you inhale and that therefore gets into your blood stream, your blood will not circulate as freely in your body as it used to, and your arteries will begin to clog. The ares furthest away from the heart, (hands and feet) will be first to get lowered their blood flow, and you will begin to experience cold hands and feet. 4. Lessened glowing of your skin: A healthy skin have a natural glow about, but with the clogged arteries, the lessened blood flow, will slowly make your skin greyer, and more pale than it used to be. 5. Ugly yellow fingertips: The smoke that several times daily gets in contact with your skin at the fingertips, is slowly going to make the fingers on the hand you hold the cigarette with into ugly looking yellow fingers. 6. Lessened ability to smell the lovely flowers: Well maybe you don't really care about the smell of flowers, but another negative effect of smoking is that rather shortly after becoming a smoker, you taste buds and your ability to smell well be severely worse than before. The good news however is that they return rather quickly after quitting. 7. Lessened lung capacity: Your overall fitness levels are determined largely by the capacity of your lungs, and a negative effects of smoking is a slowly deteriorating lung capacity. When I smoked I had a test as I were doing sport at a serious level, but had collapsed during a track test, and were told my lung capacity were well below par for my age group. 8. Lower Energy: When you smoke, your immune system never relaxes for very long. Immediately when smoke gets in your body, the immune system start fighting it, and is therefore working on overdrive so to speak. That extra use of energy has to come from somewhere, and it does. The energy used is taken from your overall energy levels, Along with that, the lesser lung capacity reduces your bodys oxygen intake, which again reduces your energy levels. so you can expect a lower energy level overall from smoking. 9. Bad breath: Often times when I were a smoker I would wake up dry mouthed, and my girlfriend refused to kiss me because of my bad breath. This point should require no further explanation. 10. Less oxygen for your brain: Lower oxygen in your blood also causes the brain to get lesser oxygen then it needs to function optimally. This may cause you to have a worse than average ability to focus on things, and it may also cause dizzy spells. http://www.itkorner.net/t506-top-10-negative-effects-of-smoking Chronic obstructive pulmonary disease (COPD) is one of the most common lung diseases.
