Secondhand smoke comes from burning tobacco products, like cigarettes, cigars, hookahs or pipes. It’s also what’s exhaled, or breathed out, by the person smoking.
Cigarette and cigarillo (like a cigarette but rolled with brown paper) smoke contains over 7,000 chemicals, hundreds of which are toxic and about 70 that can directly cause cancer. Secondhand aerosol from e-cigarettes is also harmful, containing cancer-causing heavy metals like nickel, tin, arsenic and lead.
Thirdhand smoke, which is the residue and gasses left on furniture, clothes, walls in a room or car after someone smokes or vapes, is also harmful too.
Harms of Secondhand Smoke
Secondhand smoke is dangerous for all people—there is no safe amount of secondhand smoke.
- Breathing secondhand smoke increases one’s risk of stroke, heart attack, respiratory diseases and lung cancer—even if you’ve never smoked.
- Babies exposed in utero to secondhand smoke are at higher risk of developing asthma as a child and experiencing or crib death.
- Babies and children who breathe secondhand smoke are sick more often with bronchitis, pneumonia and ear infections.
- Secondhand smoke is also harmful to pets of all kinds. Any kind of exposure increases their risk of cancers, lung and respiratory issues, eye irritation and allergies.
- For people with asthma, breathing just a small amount of secondhand smoke can trigger a severe attack.
Protecting Your Loved Ones & Pets from Secondhand Smoke
Don't smoke in or near your home.
Homes are the main places where everyone, especially children, infants and pets, is exposed to secondhand smoke. Smoking in another room, opening a window or using a fan or air filter system does not get rid of secondhand smoke.
Smoke travels under doors, windows, outlets, heating and cooling systems and through cracks. It also becomes trapped in fabrics, carpet and even on the walls, and can combine with other chemicals to create thirdhand smoke which is just as harmful. Thirdhand smoke is the residue and gas left on furniture, clothes or walls of a room or car after someone smokes or vapes.
Steps to Take:
We’ve put together a list of the best resources for youth looking to quit tobacco and nicotine:
- Remind all guests that your living space is a smoke-free home. Hang up a sign if you need to. Free signs are available through the Vermont Department of Health.
- If needed, create a designated smoking area outside, away from the home’s entryway and any common hangout or play areas.
- Leave a covered trash bin nearby for cigarette waste. In addition to being the most common form of litter, cigarette butts are toxic to infants, children and pets.
- Smoke stays in your clothing and hair. Store any clothing you regularly smoke in, like a jacket, separate and away from your family’s items. Wash your hair before taking care of children.
- Candles, air purifiers and air fresheners do not remove smoke toxins.
Make your car a smoke-free zone.
Cars are the #1 source of exposure reported by Vermont teens. There’s no way to avoid breathing in toxic tobacco smoke when in an enclosed space like a car, even when a window is down. In fact, it is against the law in Vermont to smoke any combustible product or vape in a car with a child under the age of 8.
Steps to Take:
- Remind passengers that your car is a smoke-free zone.
- Close or fill your car’s ashtray with spare change or gum to avoid the temptation to smoke.
- Store cigarettes, cigarillos or vape devices in the trunk and out of reach while driving.
The best way to protect yourself and loved ones from secondhand smoke is to quit all forms of tobacco. Quitting is hard for everyone, and often takes several attempts. Many Vermonters are successful with the help of quit smoking aids, like nicotine gum and lozenges, and confidential and counseling. Visit 802quits.org for free, personalized support.
