Passive Smoking

Exposure to secondhand smoke in a public place

Passive smoking, also known as secondhand smoking, occurs when a nonsmoker inhales the smoke from cigars, cigarettes, or pipes used by others. This exposure poses significant health risks, including an increased likelihood of developing cancer and respiratory disorders.

Overview

Passive smoking involves the involuntary inhalation of smoke from tobacco products used by others. It is a major public health issue due to its widespread impact and associated health risks.

Composition of Secondhand Smoke

Secondhand smoke is a mixture of two forms of smoke from burning tobacco products:

Mainstream Smoke

Smoke exhaled by a smoker.

Sidestream Smoke

Smoke from the lighted end of a tobacco product, which contains higher concentrations of carcinogens.

Health Risks

Exposure to secondhand smoke has been linked to several health problems, particularly in non-smokers who are regularly exposed.

Cancer

Passive smoking significantly increases the risk of lung cancer and other types of cancer.

Respiratory Disorders

It can lead to or exacerbate respiratory disorders, especially in children and infants.

Cardiovascular Diseases

Exposure to secondhand smoke is also associated with an increased risk of heart disease.

Impact on Children and Infants

Children and infants are particularly vulnerable to the effects of passive smoking, which can lead to increased risks of asthma, sudden infant death syndrome (SIDS), and respiratory infections.

Regulations and Public Health Measures

Many countries have implemented laws and public health measures to reduce exposure to secondhand smoke, such as smoking bans in public places.

These bans are aimed at protecting non-smokers, especially in enclosed spaces such as restaurants, workplaces, and public transport.

Prevention and Education

Public education campaigns focus on the dangers of secondhand smoke and the importance of smoke-free environments.
