First, it contains tar. Tar is a sticky black substances that when it is inhaled, gets stuck in the cilia of your throat and lungs. The body can normally get rid of it somewhat well except for that fact that cigarettes also have formaldehyde. Formaldehyde is the chemical used to preserve dead organisms (like a frog you would dissect in middle school). This causes the tar to stay stuck and preserved in your lungs and throat.
Next, it contains hundred of chemicals and compounds such as rat poison and carbon monoxide (both pretty toxic stuff).
Next, the nicotine gets you addicted and affects the way your neurons work in your brain and throughout your body. Not only that, but nicotine is a stimulant and a depressant. This is what makes its effects so powerful. It constrict blood vessels so blood may not get to your extremities as fast or efficient. Constricted blood vessel with blood cells coated in tar increases your risk for strokes and heart attacks. Lastly, lung cancer, emphysema, bronchitis, and Heart disease (the number one killer in America) are all directly linked to smoking.
It constricts the blood vessels, clogs the breathing passages, increases heart rate and blood pressure, turns teeth yellow, gives bad breath, suppresses the appetite so as to inhibit proper nutrition, and turns your fingernails brown.
Tobacco can create a tar like substance in your lungs, causing aesthma and to a larger extent, lung cancer. However, cigarettes are an entirely different matter, and contain chemicals that can do a variety of damage.
Nicotine is the blood vessels' constrictor. Not all blood vessels, of course, but mainly the peripheral blood vessels, including the brain capillary blood vessels.
well, smoking makes the blood vessels alot thinner than they usually are, and tbat makes it harder for the blood to be pumped to the brain.
