What is the reason (chemically) that people smoke cigarettes?

Stubbs the Zombie smokes.

Nicotine even has a receptor named after it - the nicotinic receptor, which responds to it or acetylcholine, while the (acteyl)cholinergic muscarinic receptor doesn’t respond much to it. These aren’t however much involved in addiction. It is not a big influence on dopamine, but indirectly affects addiction systems. It’s complex.

Then why so many ex-smokers ?

We’ve had more than enough smoking threads resurrected here. Let’s put this poor nicotine-addicted zombie back in his grave.
