Secondhand Smoke and Pregnancy: Get the Facts
In my post, What Happens When You Smoke During Pregnancy?, I discuss what happens to your body, what parts of your body are affected, and what happens to your baby when you choose to smoke while you’re pregnant.
But what if you’re not the one smoking? What if your husband is, or his family, or yours? Is secondhand smoke bad for your baby too?
And is cigarette smoke really that bad?
Is Cigarette Smoke really that Bad?
As I talked about in my post, What’s Actually in Your Cigarette?, there are over 4,000 different chemicals in cigarettes. In fact, many of the chemicals are poisonous and are known carcinogens (cause cancer).
And, cigarette smoke is no better, according to “chemists at R. J. Reynolds Tobacco Company, cigarette smoke is 10,000 times more concentrated than the automobile pollution at rush hour on a freeway.”  
Also, it’s been shown that the smoke burning off the end of a cigarette contains horrible substances such as tar, carbon monoxide, nicotine, formaldehyde, benzene, arsenic, ammonia, hydrogen cyanide and many others.
“Secondhand smoke causes about 3,000 deaths from lung cancer and tens of thousands of deaths from heart disease to nonsmoking adults in the United States each year.” 
Does Secondhand Smoke Affect you when you are Pregnant?
According to a study published in the American Journal of Physiology, asking someone to smoke outside isn’t enough to protect the lungs and life of your unborn child.
“The study, by researchers at the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed), found prenatal exposure to toxic components of a newly recognized category of tobacco smoke — known as “thirdhand smoke” — can have as serious or an even more negative impact on an infants’ lung development as postnatal or childhood exposure to smoke.
Thirdhand smoke is the newly formed toxins from tobacco smoke that remain on furniture, in cars, on clothing and on other surfaces — long after smokers have finished their cigarettes.” 
Both secondhand and thirdhand smoke can cause:
- Tubal pregnancy
- Poor lung development (leading to respiratory trouble after birth)
- Early birth
What can Secondhand Smoke do to your Baby?
When toxins you breathe in make their way to your bloodstream, those toxins are also shared with your baby.
And if you spent your pregnancy breathing cigarette smoke and being in contact with the residue, it can cause many problems for your baby as he/she grows.
The chemicals that are inhaled from cigarette smoke can cause:
- Learning problems
- Behavioral problems
- Sudden Infant Death Syndrome (SIDS)
- Low birth weight
- Severe allergies
- Respiratory problems throughout life, including increased risk of asthma
- Pneumonia and bronchitis
- Decreased immune system function
And there are long-term dangers that are caused to children who are exposed to secondhand smoke while growing up. For one thing, children who have smoking parents are more likely to become smokers too. And secondhand smoke may cause additional problems for those children later in life including:
- Poor lung development (meaning that their lungs never grow to their full potential)
- Lung cancer
- Heart disease
There is no safe level of exposure to cigarettes or cigarette smoke.
