Chemicals in Cigarettes: From Plant to Product to Puff
You probably know that cigarettes can kill you—in fact, smoking kills half of those who don't quit1—but do you really have the full story? Do you know how many harmful chemicals are in cigarettes or how they get into the product?
FDA created these videos and interactive tools to lay the foundation for an important public health goal: we aim to publish a list of the levels of harmful and potentially harmful chemicals in tobacco, in a way that is easy for the public to understand. As an important step toward that goal, we invite you to explore the chemicals in tobacco in three stages of cigarettes, from plant to product to puff, in the videos below.
Chemicals in Every Tobacco Plant
It is a fact that cigarettes contain dangerous chemicals.2 But how do these chemicals get into cigarettes? Are most of the harmful chemicals added during the manufacturing process?
Fact: Some of the toxic chemicals in tobacco are present in the plant itself.3Watch the tobacco growth video to uncover more.
Chemicals in Every Cigarette Product
Ok, so harmful chemicals are in the tobacco plant. What happens during manufacturing? Is that when more dangerous chemicals are added?
Fact: Not all of the harmful chemicals created during cigarette manufacturing are man-made. Some of the carcinogens occur naturally as tobacco is cured.3Watch the video about cigarette manufacturing.
Chemicals in Every Puff of Cigarette Smoke
How many harmful and potentially harmful chemicals are in a cigarette? Is there more than nicotine and tar?
Fact: There are more than 7,000 chemicals in cigarette smoke.2 More than 70 of those chemicals are linked to cancer.4,5,6,7Watch the video on cigarette smoke to learn more about what happens when you light up.

Tobacco products that are labeled or advertised with the terms "light," "low," or "mild" or similar descriptors mislead the public into thinking that these products cause fewer health problems than other cigarettes. However, they still pose a heavy health risk. Research shows that:
Smokers who use light cigarettes do not reduce their risk for developing smoking-related cancers and other diseases.1
Switching to light cigarettes does not help smokers quit, and may actually decrease the motivation to quit.2,3
In order to better protect the public from misleading claims, the Family Smoking Prevention and Tobacco Control Act prohibits manufacturers from producing and distributing for sale any tobacco products labeled or advertised as "light," "low," or "mild" without a Modified Risk Tobacco Product order from the FDA. Manufacturers must meet rigorous criteria before we can issue an order authorizing the marketing of a modified risk tobacco product. If products are marketed as "light," "low," or "mild" without an MRTP order, FDA considers these claims to be health fraud.

Nearly 7 percent of all high school aged girls smoke cigarettes.3
Impacts of Smoking on Women and Their Families
There's abundant research about the many harms of smoking—whether it's the dangerous chemicals, the addictive properties, or the damage smoking causes to the body, these effects can have a profound impact on not only your own body, but also those around you. Here are some facts about smoking's effects on women, families, babies, and pregnant moms.
For Women
Smoking causes coronary heart disease, cancer, and stroke—the first, second, and fourth leading causes of death for women in the United States.4
Smoking cigarettes causes chronic obstructive pulmonary disease (COPD). People with COPD have trouble breathing and slowly start to die from lack of air. Women who smoke cigarettes are up to 40 times more likely to develop COPD than female nonsmokers.5
Life expectancy for smokers—both male and female—is at least 10 years less than for nonsmokers.6
For Families
Secondhand smoke causes disease and premature death in nonsmoking adults and children.7
The U.S. Surgeon General estimates that living with a smoker increases a nonsmoker's chances of developing lung cancer by 20-30%.7
Exposure to secondhand smoke increases children's risk for ear infections, lower respiratory illnesses, more frequent and more severe asthma attacks, and slowed lung growth, and can cause coughing, wheezing, phlegm, and breathlessness.7,8
Teens are more likely to smoke if they have friends or family who smoke.9
For Babies and Pregnant Moms
Smoking during pregnancy can affect the baby's health.10
Infants born to mothers who smoked during pregnancy are at a higher risk of low birth weight, birth defects like cleft palate, lungs that don't develop in a normal way, and sudden infant death syndrome.4,8
Next Steps
The good news is that you can do something about it now—smoking truly is what the CDC terms a "modifiable" risk factor.
Encourage the women in your life—the mothers, daughters, sisters, and friends—to put their own health first by finding a quit method that works for them.
