One of my family members smoked for the first time today inside the kitchen. He took a few puffs and then went outside to smoke, but the room smelled like cigarettes, we then turned on the kitchen ventilation fans and waited a while till there was no smell. Should I be worried of the third hand smoke on the surfaces from just a few puffs? How long does it take to go away. I've asked so many subreddits but no one took me seriously, please help I'm desperate.
