Research has shown that it takes a long time of constant smoking to actually become dependent on the nicotine. People like the affects of the nicotine and get used to it which causes them to desire more. Much of the dependence of nicotine is psychological. Smokers think that they need tobacco to rest, relax, reduce anxiety, control their appetite, because they use it so often to control these problems that they begin to think that smoking is the only way to be in control. This is where the dependence begins for many people.
There are a lot of jobs throughout the world which depend on tobacco and cigarettes. Without tobacco, many people in developing countries would be out of jobs. Tobacco is important to the economy in terms of growth and development.
