Secondhand Smoke

CHILDREN How We Can Protect Our

(Humo de Segunda Mano)

Secondhand smoke is a danger to our 

children and our families.

Secondhand smoke comes from lit cigarettes and cigars. It also 

comes from smoke breathed out by smokers. When children 

breathe secondhand smoke, it is like they are smoking, too. 

Secondhand smoke is made of thousands of chemicals. Many 

are poisons that stay in your body. What do these poisons do? 

The U.S. Surgeon General asked scientists to find out. They 

found that secondhand smoke harms everyone, especially 

children. They also learned that

• An estimated 58 million nonsmoking Americans, including 14 million

children aged 3-11 years, are exposed to secondhand smoke.

• They breathe it at home, day care, and in cars.

• Most Hispanic adults do not smoke. But our children pick up

habits from people around them. Our teens now smoke as much as

other teens.

Here are just a few of the chemicals and poisons in tobacco smoke.

How does secondhand smoke hurt 

our children?

Tobacco smoke harms babies, even before they are born. It 

harms children, too, because their lungs and bodies are still 

growing.

• Babies who

breathe

secondhand

smoke are more

likely to die

unexpectedly

from sudden

infant death

syndrome (SIDS),

also called crib

death.

• Babies and

children

who breathe

secondhand

smoke are sick

more often

with bronchitis,

pneumonia, and

ear infections.

• For children with asthma, breathing secondhand smoke

can trigger an attack. The attack can be severe enough to

send a child to the hospital. Sometimes an asthma attack

is so severe that a child dies.

Smoking during pregnancy can cause your 

baby to be born too early and have low birth 

weight. If you smoke, your baby is more 

likely to become sick or die.

Children can’t hide from secondhand 

smoke at home. Here’s why...

Smoking in another room like a bathroom or bedroom 

pollutes all the air in your home. In an apartment, smoke in 

one room can go through the whole building.

• Smoking outside in a hall or stairwell does not protect

children inside. Smoke goes under doors, windows, and

through cracks.

• To protect the children inside, homes and apartment

buildings must be smoke-free.

No amount of secondhand smoke is safe. Even when you 

can’t smell it, cigarette smoke can still harm your child.

• Opening a window or using a fan does not protect

children.

• Air purifiers and air fresheners do not remove smoke’s

poisons.

• Smoke from one cigarette can stay in a room for hours.

Don’t smoke at home, even when children aren’t there.

Allowing people to smoke 

in only one room does not 

protect children. Smoke 

from halls and stairs gets 

inside, too.

We must protect children from 

secondhand smoke everywhere. 

At Home. If you take care of children in your home, do not 

allow anyone to smoke inside. Do not let babysitters, family 

members, or friends smoke around your children.

In Day Care. Make sure smoking is not allowed in your 

child’s day care.

At School. Make sure your child’s school is smoke-free 

inside and out. All school events should be “No Smoking.” 

In Public. Choose restaurants and businesses that are 

smoke-free. “No Smoking” sections in restaurants do not 

protect children from secondhand smoke.

In Your Car. Do not allow anyone to smoke if children are 

riding in your car. Rolling down a window does not protect 

them.

Our children are so important that we should ask family members and 

visitors not to smoke around them.

Hispanic adults smoke less than most other groups in the United States. 

But our teens need our help to choose good health and not start smoking.

Take simple steps to protect your 

children from secondhand smoke. 

Children respect and learn from your actions and words. 

As caregivers, we teach our children by the choices we make. 

• Ask people not to smoke around your children.

• Support family and friends who want to stop smoking.

• Decide to have a smoke-free home and car. Put an “Aquí

no se fuma” sign where everyone can see it. Ask family

and friends to respect your decision.

• Get rid of all ashtrays in your home.

• Teach your children to stay away from secondhand

smoke. Encourage your teens not to smoke.

• If you smoke, quit. Ask your doctor, family, and friends

to help. Call this free quit-line: 1-800-QUIT-NOW

neighbors smoke?

Do you allow smoking in your car?

Do your children visit places where 

people are smoking?

Is smoking allowed outside your day
