Secondhand & Thirdhand Smoke

Secondhand and Thirdhand Smoke

In the air and on surfaces.

Smoke and aerosol vapor from tobacco or nicotine products can affect both the air you breathe and the spaces you share.

Secondhand smoke is the smoke others breathe in when someone is smoking or vaping nearby.

Thirdhand smoke is the invisible chemical residue left behind after smoking or vaping. These harmful chemicals build up on surfaces like clothing, furniture, walls, and cars long after smoking or vaping stops. 

The Risks Are Real

There is no safe level of secondhand or thirdhand smoke. Opening windows or using fans won’t remove these harmful chemicals. They stay on surfaces, putting kids, family, friends, and pets at risk. These chemicals can be inhaled, swallowed, or absorbed through the skin.

For Babies: Secondhand smoke can lead to sudden infant death syndrome (SIDS). Thirdhand smoke can expose babies to toxic chemicals on floors and toys they touch, which can harm their health.

For Kids: Secondhand smoke can cause asthma, sore throats, ear infections, breathing problems, and learning difficulties. Thirdhand smoke can trigger asthma and breathing problems when kids are exposed to these chemicals.

For Pets: Secondhand smoke exposure doubles the risk of cancer in pets. Thirdhand smoke can build up on floors, surfaces, and even fur, increasing the risk of health problems.

General Risks: Secondhand smoke contains thousands of chemicals, with at least 69 known to cause cancer. Thirdhand smoke leaves toxic residue that can build up on surfaces and increase health risks over time.
