Some people find it so easy to quit smoking because they have only one problem they're dealing with, and that is the lifestyle, the environment, the habit , the rituals and routines of smoking. Their nicotine addiction itself is not very strong and when they make a decision to quit smoking, they don't have severe withdrawal symptoms, they don't feel terrible, they lay their cigarettes down and they go about their way. This is once they make up their mind. About 10-20% of the population of smokers find it easy to quit smoking. The vast majority find it much more difficult because the way they feel, their withdrawal symptoms or their whole life environment is just wrapped around their smoking in such a way that holds them very tightly. There are other underlying conditions that you need to consider, too, such as depression or other mood disorders for which cigarette smoking really makes someone feel much better and when they quit smoking their symptoms significantly increase to the point where they find life unmanageable. So the long risk people, I call them, are the ones who aren't heavily addicted, they don't have to smoke the first thing when they wake up in the morning, they can go for hours without minding having a cigarette. Those people, when they quit, don't have much that pulls them back in. But the people who have a very strong addiction, a brain chemistry disorder set up by their nicotine dependence, and when they have an underlying condition that makes them want the cigarette to treat that problem, those individuals have a much more difficult time quitting smoking, and need professional help. But with that help they can be just as successful in the long run.
