Chapter 21, lesson 3 objective:

2. Words to know Environmental tobacco smoke (ETS) – secondhand smoke
Mainstream smoke: the smoke exhaled from the lungs of a smoker
Side stream smoke: the smoke from the burning end of a cigarette, pipe or cigar.

3. Risks for Smokers and Nonsmokers
Both smokers and nonsmokers who breathe air containing tobacco smoke are at risk for health problems.
Between second hand smoke (ETS), environment tobacco smoke that is composed of mainstream smoke and the smoke from the burning end of a cigarette (side stream smoke)’; these all display ways of health risks for breathing it in.
Side stream smoke is more dangerous than mainstream because it has higher concentrations of carcinogens, nicotine and tar.

4. Effects of smoke on nonsmokers
Environmental tobacco smoke from cigarettes and cigars contains more than 4,000 different chemical compounds, 43 of which are identified as carcinogens.
Inhaling this smoke either by smoking or someone else brings these carcinogens into your body.
Secondhand smoke affects people of all ages, causing eye irritation, headaches, ear infections, and coughing.
It worsens asthma conditions and other respiratory problems.
Every 3,000 people are diagnosed with lung cancer caused by second hand smoke.

5. Effects of Smoking on Unborn children and infants
Smoking during pregnancy can seriously harm the developing fetus.
Nicotine passes through the placenta, constricting the blood vessels of the fetus.
Carbon monoxide reduces the o2 levels in the mothers and fetus’s blood.
This all increases the risk of impaired fetal growth, high levels of carbon monoxide, miscarriage, prenatal death, premature delivery, low birth weight, deformities and stillbirths.

6. What happens to a fetus if you smoke while pregnant

7. Effects of Smoke on Unborn Children and Infants
The infant may also suffer from growth and developmental problems throughout the early childhood.
Babies of smokers are two and a half times more likely to die of sudden infant death syndrome (SIDS).
One study found that nearly 60% of all SIDS cases could be prevented if babies and pregnant females were protected from tobacco smoke.

8. Effects of Smoke on Young Children
Young children are also particularly sensitive to
environmental tobacco smoke.
Children of smokers are nearly twice as likely
to be in poor health as those of nonsmokers:
Children of smokers tend to have a higher incidence of sore throats, ear infections, and upper respiratory problems than children of nonsmokers.
Children who live with smokers have double the risk of developing lung cancer than children of nonsmokers

9. Reducing your Risk
What can you do to protect yourself from ETS (second hand smoke)?
If you and your family want your home to be smoke free, politely ask visitors to refrain from smoking inside.
If someone in your household smokes, open windows to allow fresh air to circulate
Consider using air cleaners to help remove contaminants from the air.
What else could you do to lessen your risk of second hand smoke?

10. Toward a Smoke-Free Society
As people realize that smoking causes diseases and harms not only their own health but also the health of others, the drive to become a smoke-free society increases.
Many states have taken steps
to prohibit smoking in all public
buildings and private workplaces.

12. Group Activity
The Dangers of ETS (Environmental Tobacco Smoke) has prompted some states to pass laws that prohibit all tobacco use in public buildings.
With the group at your table, list some measures that can be taken to protect the health and well-being of nonsmokers. I need at least 7 at the minimum.
We will discuss our answers.
