Anytime you hear someone say they need a cigarette, it usually means they want to make themselves feel better in some way. It is hard for a non-smoker to understand how puffing on and inhaling burning tobacco that stinks so bad could make anyone feel better. It does make someone that is addicted to the nicotine in the tobacco feel better, but this only lasts for a short while and then they have to smoke some more. After many years, and sometimes not even that long, smoking will not be making them feel better, but it will literally make them sick.
The feel good aspect of smoking a cigarette rarely lasts for very long. All a smoker is doing is feeding their addiction to nicotine and the smoking habit itself. Most of the time a smoker will just do it mindlessly as if it is the most natural thing in the world to them. They no longer give it any thought, they just do it. As long as they get their nicotine fix on a regular basis they are fine. If you suddenly take their cigarettes away, you could have a real fight on your hands. Running out of cigarettes can send a smoker into a panic if they think they are not going to get one soon.
Even after many years of smoking, this urgent craving to smoke does not normally diminish. As a matter of fact, even when some smokers are diagnosed with serious health issues because of it, many of them continue to smoke just like always. Sometimes it is because they have given up hope of quitting and think there is no sense in quitting now. Smokers often become so discouraged by attempting to quit and failing that they do give up. For some of them it is just too hard to go through the withdrawal. It is not necessarily the withdrawal from nicotine because that usually only lasts for a few days. It is the emotional withdrawal from the smoking habit itself that keeps them from quitting.
People that are trying to stop smoking have a hard time learning to live without the habit that they have been practicing for long. When you are accustomed to putting something in your mouth and holding it in your hand for five to ten minutes at a time up to and beyond twenty times a day, it creates a void that they way to find a way to fill. Most regular smokers will use a pack of twenty a day, sometimes more than that. This means that while they are awake they are lighting a cigarette about once an hour or more. This can take up a big part of the day. It is a repetitive procedure they do over and over. They have programmed themselves to light a cigarette many times a day. It becomes almost like breathing to them. The only thing is that when they do it for years and years, they will eventually have to give up breathing because they will not be able to.
