A big part that is often not talked about is the oral fixation. A lot of smokers smoke because they use it as a mental break--both day to day life at work and at home--and like having something to do idly. Feeling restless or anxious? Go have a cigarette and think about what to do next.

That physical habit is a powerful thing. Some people can replace cigarettes with vapes, but it isn't the same thing.

Same is true with patches and gum. Those can help with nicotine cravings, but they do nothing for the physical habit that many smokers really enjoy.
