The substance in tobacco that causes addiction is called nicotine. Nicotine is a stimulant that causes us to temporarily feel good or energized. If you are depressed, it can provide a short boost. It also causes the release of natural chemicals in our brain called beta-endorphins. These chemicals cause us to feel more alert and calm. The problem is that nicotine isn't stored in the body so these effects last only a few minutes. We need to absorb more and more nicotine to make the effects last.
If we consume nicotine long enough, our brains may compensate and lower our natural energy level or mood. So, instead of providing a temporary high, people smoke just to feel "normal". When some people go without tobacco for more than a few hours they may experience withdrawal symptoms such as lack of energy, slight depression, and difficulty concentrating. They smoke to avoid feeling this way. But when you quit for good, withdrawal symptoms will pass within a few days. This is evidence that your body has begun to heal itself.
Nicotine is also highly addictive because it causes changes in your brain.

I freaking love to smoke. I love to smoke cigarettes, joints, cigars, whatever.
I also should not smoke. It is a profoundly stupid thing to do. It does not seem very "cool" to me.
So I quit. No smoking for me. Again. For the nth time. When I quit, I quit cold turkey, and I have no withdrawal symptoms to speak of. But I do miss it, because I really, really like to do it.
If I get a terminal disease, or get really old, or am otherwise near death, and you want to find me, just look for the dense cloud of fragrant, delicious smoke surrounding a happy sinner.
