Is it safe to smoke cigarettes or vape indoors with kids in the home?
No. Keep smoking and vaping outside, away from doors, windows, and kids.
What is in it
Cigarette smoke contains cadmium, nicotine, fine particles, and many combustion byproducts. Vape aerosol can contain nicotine, tiny particles, metals, and flavoring byproducts.
Opening a window or smoking in another room does not protect kids. Residue can settle on walls, furniture, carpets, clothes, and car seats.
What the research says
CDC says secondhand smoke harms children and that e-cigarette aerosol can contain substances that are harmful or potentially harmful.
EPA says thirdhand exposure can happen from contaminated surfaces and from chemicals released back into indoor air. EPA says the only way to eliminate secondhand exposure is to prohibit smoking and vaping indoors.
A 2026 Biological Trace Element Research study also estimated health risks from cigarette-related cadmium exposure.
What to do
Smoke or vape only outdoors, away from doors, windows, vents, and kids. Wash hands before holding a child. Change a smoky sweatshirt or jacket before coming back inside.
If a home or car has been smoked in, clean hard surfaces, wash fabrics, replace HVAC filters, and keep kids away from dusty carpets while cleaning.
