(NBC) - The dangers of secondhand smoke are well documented, but now a new study looked at thirdhand smoke.
It's what's left hanging around after the smoke clears.
Burning tobacco releases nicotine into the air, and experts said it clings to furniture, carpet, walls and your clothing for days, weeks, even months.
Researchers said when this thirdhand smoke reacts with indoor air pollutants, usually from unvented gas fireplaces or heaters, it can form carcinogens.
Young children are most at risk because they're more likely to be on the floor or touching a smoker's clothing, and can breathe in these carcinogens.
