What’s in Them May Surprise You

Researchers continue to learn how cigarettes harm health

Cigarettes have been around for centuries, but their many risks have been increasingly well understood in recent decades. Despite declines in the cigarette smoking rate, it remains the leading preventable cause of death in the United States.1 Tobacco companies have used false claims and sneaky marketing to make these products seem “healthy,” pushing flavored cigarettes, cigars, cigarillos, and menthol cigarettes at various populations to get and keep them addicted.

What You Need to Know

The chemicals in cigarettes can harm your health and take years off your life

70 of the chemicals in cigarettes are known to cause cancer

Chemicals found in cigarette smoke include:2

  • Nicotine, found in all cigarettes, produces a short-term “buzz” that quickly hooks users.
  • Lead (a toxic metal)
  • Carbon monoxide (a colorless, odorless gas that prevents blood from carrying oxygen)
  • Ammonia (used in cleaning products)
  • Formaldehyde (a colorless gas used to preserve bodies in mortuaries)
  • Arsenic (a poisonous chemical often used in rat poison)

Cigarettes are addictive

Cigarette smoking harms nearly every organ of the body and causes cancer, heart disease, stroke, lung diseases, diabetes, and chronic obstructive pulmonary disease.2

  • 10.7% of Colorado adults smoke. That’s about 625,000 people.3
  • 20.8% of high school students in Colorado have smoked a cigarette, even for just one or two puffs.4
  • 8,700 kids under 18 try cigarettes for the first time each year.5
  • Cigarette smoking kills more than 5,100 Coloradans each year.5
  • Smoking kills more people than alcohol, AIDS, car crashes, illegal drugs, murders, and suicides combined.1
  • If you quit by age 40, your risk of dying from a tobacco-related disease decreases by 90 percent.6

Menthol Cigarettes are Just as Dangerous – If Not More

  • Menthol cigarettes contain a substance that provides a cooling sensation and masks the harshness of tobacco smoke, making it easier to inhale deeply.
  • Research suggests that menthol cigarettes may be more addictive and harder to quit than non-menthol cigarettes, and they are often marketed specifically to younger and minority populations.7
