Wash every item of clothing in the house, including your pillows if you can. Draperies may or may not be washable. If they are, wash them. If not, Febreeze (little though I like the stuff). Detectable scent came off the throw I use on a table the television sits on. Into the washer that went!
Clean your carpets if you have carpet. Wash hardwood floors if you have them.
Consider washing your walls. 1 cup white vinegar in 1 gallon of water will remove a shocking amount of smoke buildup and brighten the room(s). That's usually only necessary in smaller rooms where you smoked a lot--in my case, just my home office, which was disgusting. The rest of the house was clean enough to ignore.
Wash the windows. They look great without the smoking grime on them! (You may find that in cold weather and using high VG you get a film on your windows from
vaping, it comes off really easily with any cleaner--I use vinegar again at 1 C per 1 G water).
In the car, wash every surface you can reach with 1 cup white vinegar in 1 gallon of water. Prepare to be disgusted. You can do the windows as well. Clean those carpets if you can; the foot rest carpets can frequently be hosed off, sprayed with soap, scrubbed, hosed, and dried in the sun on a nice day in April or May. Febreeze or take it to be detailed if you can't.
Don't forget the trunk! An amazingly powerful cigarette stench came from mine...
(Honestly, just nuke it from orbit. It's the only way to be sure...)
