Newborns and cigarette smoke.

So I just feel like my house just has so much cigarette smoke in it I shampooed all the carpets and washed the curtains and I don't know how many times I will have to do this before my sweet baby boy arrives because everyone keeps smoking in the house . I'm just really nervous about bring my baby in here they say they will stop smoking in the house once the baby is born but Im just worried the air won't be clean enough and I can't move until March 1st so I'm really freaking out. Am I just parinoid or is there something that I should do?? I just want my little baby to be safe and the smoke is really stressing me out. Some may say " tell them to stop smoking in the house now" but they won't so that's a no go what tf should I do.
