Addictive Potential of Tobacco

1. Nicotine is the chemical inside tobacco that makes it so addicting. It is one of the most addicting substances known to man.

2. 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

3. 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

4. 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.

Effects of Tobacco

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. 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.

This exposure was estimated to have caused 379 000 deaths from ischaemic heart disease, 165 000 from lower respiratory infections, 36 900 from asthma, and 21 400 from lung cancer http://www.sciencedirect.com/science/article/pii/S0140673610613888

This effect is larger than one would expect on the basis of the risks associated with active smoking and the relative doses of tobacco smoke delivered to smokers and nonsmokers. http://circ.ahajournals.org/content/111/20/2684.short
