Im sorry to have to differ here.

But the smell of smoke scares the life out of any wild animals.
We have a fireplace in the house and my snakes are housed in the room the furthest from it.

When there is even a slight smoke smell in the room, the Balls will go straight into their hides.

I guess this is a natural reaction.
But i have also seen smokers who raised their snakes from young in a smokey environment, without this issue.

I guess its all about conditioning.
