RE: The dangers of third-hand smoke อันตรายจากควันบุหรี่มือสาม
The nicotine in third-hand smoke residue reacts with common indoor air pollutants, such as nitrous acid and ozone and goes on to form carcinogens, or compounds that may cause cancer.
Efforts to diffuse the smoke, such as opening windows or using a fan, don’t prevent third-hand smoke from forming or keep it from being inhaled. And this residue may give off harmful chemicals for years or even decades.
