I'm a former smoker and was obsessed with having my house smell fresh and not smokey. Most people said they never knew I smoked, so I don't think my clothes smelled of smoke very much. That being said, my daughter would wash everything that I sent her and I would never have any gift I sent in a room that was smoked in. She wasn't bothered when she lived at home but after she got away from it, she could smell it a mile away. Some people are super sensitive to smoke and others it only bothers a little. And I think it depends what type of cigarettes they smoke also. I used a lot of Febreeze. I'd spray the drapes, the sofa, the carpet, the closets. I'd give selling your stuff a try, if you are doing it online tell them your situation and say you will launder right before you post it and it's up to them if it needs more laundering. And I agree with others I have purchased things at stores that had an odor and washed it as soon as I got inside the house.
