Best primer to block cigarette smoke smell?

[Lara Fobian]

What’s the best type of Kilz primer (or other primer) to use on a bedroom’s walls and ceiling to permanently eliminate or cover up a smoky cigarette smell from someone who smoked in a bedroom?

I know some of the smell could also be in the carpet and pad (which is being REPLACED), so should the concrete subfloor under the pad also get coated in the same odor-blocking primer?

I’m curious on the general consensus.

Thanks!
