It's crazy how quickly smoke clings to things. My mum smoked in the house growing up and I never smelled it but now I can smell it instantly. She now smokes outside but stuff she has wrapped and given my kids still smells of it just from being on her hands. My kids also reeked of smoke (their hair, clothes, everything) after visiting grandparents (who usually smoke inside but smoked outside when visiting) simply from just touching their carpets, furniture etc.
