They like to smoke Addiction

For the same reason people continue to use heroin, cocaine, crack and even,in some cases, alcohol...it's an addiction and nicotine is VERY addictive, actually it's more addictive than heroin.

I think they become addicted to it and can't live without it. I suggest them to go to the hospital as soon as possible. And there should be posters or advertise not to smoke.

i smoke! i enjoy it plain and simple. i was likely imprinted heavily by my grandfather and aunt at an early age. they were in my life pretty frequently.. it always felt familiar...

Probably because the bad habit developed though addiction.

Because, at age 70, after smoking for 60 years, I feel certain that quitting smoking would be far more damaging to my health, mental and physical, that continuing the practice. I also believe that the quitting trend is treated far too casually by individuals and, particularly, the medical profession...especially where the person has smoked for several years, even far less than I. The properties in tobacco products have such an impact on the function of the brain that rules the other organs of the human body, the sudden or even gradual denial of those properties needs to be managed for as much as a lifetime. I made an attempt to quit approximately 12 years ago, and was "successful" for some 15 months. But my physical and mental reactions were extremely negative. Almost immediately after re-starting, things got back to "normal". Again, at 70, I would not make that foolish attempt again. BTW, unlike all the people I know who have quit smoking, and who are in and out of doctors' offices all the time, with one malady or another, I have needed the services of the medical profession only three (3) times in the past 30 years! I had a physical last year...and, viewing all results of mounds of testing, my primary doctor shook his head and told me not to change one thing in my life that I am doing. One other BTW...I don't want to stick my nose in other peoples' business and personal choices, and I take personal offense when others attempt to stick theirs in mine.

Because nicotine is probably the most addictive substance in widespread distribution.

Most people if not all people know that smoking is a bad habit. However some people keep on smoking because they are already hooked to this bad habit and are unable to break free from the addiction. They are many methods available to assist these smokers to breathe free again but they are either unwilling to give up this pleasure or afraid of the "suffering" due to withdrawal effects.

Some people keep smoking because they're pissed off with the smoke nazis. Here's an education on how smokers feel about constantly being harrassed by militant non smokers:

Addicted and the wife smokes.

addiction isn't easy to just walk away from - some people can do it easier than others

Because they are addicted to it. When habits turn to addiction, it's a hell of task to quit it. Beside, a person body becomes so much used to nicotine, that it's always hard to get rid of it so quickly.Why is tobacco so addicting? It is because nicotine acts as a stimulant, which is stimulating the mind, body, and spirit. When the body tolerance levels high then one ends up needing to use larger doses of nicotine to maintain a certain level of the physiological effect. When the body becomes accustomed to the presence of nicotine, it then requires the use of the chemical to help the body to function normally. This level of dependence is referred to as an addiction.

Because they are addicted, maybe they dont care and so on. Its the same with drugs, people know the effects, so why do they keep doing it?

I am addicted. For years. You younguns out there. Don't start.

Because they're more interesting than non smokers.

Because they are looking for a crutch.

b/c they are addicted and they still think its cool.

it makes them feel good!!!!!!!!!!!!! gawd im so wired

I think everyone needs a vice...mine is Pepsi. I know it's the root of all my problems but the caffeine addiction is hard to kick!!

it's part of my routine. without it i would be lost

Bad or good, it's still a habit. You don't just change your habits because others deem them 'bad'.

Same reason they keep going to the McD's drive-thru and shoving quarter-pounders and BigMacs in their face. People want what they want and the consequences be damned. People are usually their own worst enemy and smoking cigarettes and eating craptastic food proves that, along with all the other destructive behaviors that humans engage in.

I have heard it is one of the most addictive things a person can do. So even when they know it is bad for them and they are coughing up blood and wheezing with every breath..they don't know how to give it up. I am not trying to funny or mean, I know a lot of otherwise smart people that are killing themselves with cigarettes. It is as addictive as meth seems to be.

It is a stimulant that some people use for a small mental boost. It also is associated with a break time. Moreover, quitting is difficult because those who have become dependent on the drug will have their bowl movement, and sleep cycles disrupted (this is true for caffeine too). It is easier to quit if one follows a good diet and morning anaerobic exercise regimen as an energy replacement.

We're just bad people.

If nobody had bad habits, the term would not even exist...

Just three reasons cross my mind. (1) Some people do not consider smoking as bad and hence they will stay with their habit. (2) Addiction can be a tremendous force to break away from. Two friends have commented that they are prepared to give up their wives instead of their smoking habit. (3) Some people have reached the stage to call smoking a pleasure. They can go momentarily without food & drink but not their smoke.

because its a habit and all habits are hard to break

People are well aware what the effects of smoking can have on their health.They do it out of personal choice and its their right to smoke.They must be fully aware of the dangers it can cause them in later life,and most will know someone who has died of a smoking related disease such as,acute myeloid leukemia and cancers of the cervix, kidney, pancreas and stomach; abdominal aortic aneurysm, cataracts, periodontitis and pneumonia.Maybe they say to themselves it will not happen to me,I will be one of the lucky ones who will live to a ripe old age.Suddenly they develop one of the diseases related to smoking.They suddenly have to have radium treatment or chemotherapy to try and arrest the cancer in their lungs and other vital organs.They will have a short time to reflect on their smoking habit when they are lying in a hospice bed hook up to a morphine drip,and my then say to themselves,well I have no one too bame but myself.After all it was their choice to start smoking and their choice not to take any notice,and it was their choice that they chose to end their lives prematurely.Humans do have free choice,and some use it wisely and some do not.

As they can't foresee that they are going to be addicted to smoking, Like so many other things drugs, alcohol. Why smoking is so addictive, because cigarettes contain nicotine and nicotine acts as a stimulant, which is stimulating the mind, body, and spirit. When the body tolerance levels high then one ends up needing to use larger doses of nicotine to maintain a certain level of the physiological effect. When the body becomes accustomed to the presence of nicotine, it then requires the use of the chemical to help the body to function normally. This level of dependence is referred to as an addiction.
