Understanding the Health Risks of Passive Smoking

Secondhand smoke is a major health concern, posing significant risks to non-smokers. Exposure to secondhand smoke can lead to a range of respiratory and cardiovascular problems, including lung cancer, heart disease, and stroke. As secondhand smoke lingers in the air and on surfaces, it is crucial to understand its persistence and the potential health consequences it carries.

How Long Does Secondhand Smoke Linger?

In the Air: Secondhand smoke particles can remain suspended in the air for several hours after a cigarette is smoked.

On Surfaces: Nicotine and other chemicals from secondhand smoke can settle on surfaces, such as furniture, clothing, and walls, where they can linger for days or even weeks.

On Clothing and Hair: Secondhand smoke can adhere to clothing and hair, potentially exposing non-smokers to its harmful effects even after leaving a smoky environment.

Hard Surfaces (e.g., tables, counters)	2-5 days
Fabrics (e.g., curtains, upholstery)	1-2 weeks
Clothing and Hair	1-3 days
