Study Notes
Definition of Secondhand Smoke
- Secondhand smoke (SHS) is smoke from burning tobacco products such as cigarettes, cigars, hookahs, or pipes.
- Also known as passive smoke or environmental tobacco smoke (ETS).
Mechanism of Exposure
- SHS occurs when non-smokers inhale smoke that is exhaled by smokers or smoke emitted from burning tobacco.
- This includes both mainstream smoke (inhaled and exhaled by the smoker) and side-stream smoke (released from the burning end of a cigarette or other tobacco products).
Health Risks
- Secondhand smoke contains numerous harmful chemicals and toxins similar to those found in firsthand smoke.
- Exposure to SHS can lead to serious health consequences for non-smokers, including respiratory issues and heightened risk of developing chronic diseases.
Regulatory Measures
- Many locations have established prohibitions on smoking in public areas, schools, and some residential properties to protect non-smokers from the dangers of SHS.
