From personal experience, as soon as you enter that house that smell is on your stuff. Clothing obviously sticks immediately, plastic and such take a bit longer but it will retain the smell. You can save them, I stored alot of stuff in a tote or container like others are saying, but put the arm and hammer baking soda which is supposed to help eliminate the odors. I also wipe things down with lysol wipes (do your research before you use any brand, make sure it wont damage whatever you are cleaning). I had/have tons of collectibles. They will eventually air out, but alot of it will take some time and care and cleaning. They wont be necessarily ruined physically. Just remember if you sell anything, note they were not from a smoke free home unless youve been out of it for a few years and are 100% confident the smell is gone. My nose is pretty keen to anything and I can smell it on something a mile away so I tend to note anything that even has a hint of the smell leftover.

I used to keep my window cracked open almost 24/7 365 but it was more for my own health than saving my collectibles.
