​Why don't people want to quit smoking?

To clarify a bit the question: I have been browsing the quit smoking Facebook groups and noticed some patterns:

1. they try to use another substance to quit nicotine

2. they try to use another type of smoking with less negative consequences than usual cigarettes

3. they don't do any research

4. they give each other advices that are profoundly false

And probably the most important thing, they utterly ignore the fact that addiction is mostly a psychological problem and is cured by using psychology.

To my shock, even patients with COPD, scared and staring death in the face do not want to use a program to help them quit.

How is this possible? I really do not understand how people try everything to quit smoking, except what actually is proven scientifically that works.

Do you know somebody like this, can you provide some input? What would it take to educate people to use psychology to quit smoking?
