  • Tobacco smoke contains more than 7,000 chemicals, including hundreds that are toxic and about 70 that can cause cancer.
  • There is no risk-free level of exposure to secondhand smoke.
  • Secondhand smoke causes lung cancer in adults who have never smoked.
  • Secondhand smoke causes nearly 34,000 premature deaths from heart disease each year in the United States among nonsmokers.
  • Exposure to secondhand smoke has immediate adverse effects on the cardiovascular system and can cause coronary heart disease and stroke.
  • Breathing secondhand smoke can have immediate adverse effects on your blood and blood vessels, increasing the risk of having a heart attack.
  • Secondhand smoke harms children and adults, and the only way to fully protect nonsmokers is to eliminate smoking in all homes, worksites, and public places.
  • Evidence from peer-reviewed studies examining objective measures such as taxable sales revenue and employment levels shows that smoke-free policies and regulations do not have an adverse economic impact on the hospitality industry.


  • Every year, tobacco companies spend billions of dollars on advertising and promotion, and tobacco use costs the United States billions of dollars in medical expenses and lost productivity.

  • Diseases from smoking kill more African Americans each year than car crashes, AIDS, murders, and drug and alcohol abuse combined.
  • Smoking cigarettes puts people at risk for heart disease, cancer, and stroke, which are the three leading causes of death for African Americans in the United States.

  • E-cigarette cartridges can contain carcinogens, such as nitrosamines and diethyleneglycol.
  • The vapor exhaled from e-cigarettes contains measurable amounts of carcinogens and toxins including formaldehyde and acetaldehyde
  • Nicotine, the main component in both e-cigarettes and cigarettes, is a highly addictive chemical that can increase the likelihood of developing heart disease, high blood pressure, ulcers, and can lead to fertility problems.
  • One study found that nicotine can cause the formation of carcinogens when it reacts with nitrous acid found in indoor air.
  • E-cigarettes have been found to have immediate adverse physiological effects after short term use. This includes lung flow resistance and lower concentrations of exhaled nitric oxide, a sign of bronchial inflammation.
  • Other studies suggest that using e-cigarettes could lead to permanent changes in lung functioning.
  • E-cigarette users have the option to refill their cartridges, which can be dangerous due to the concentrations of nicotine present in these refillable cartridges.
  • Nicotine refill bottles contain up to 7 grams of nicotine, more than 10 times more than the amount of a fatal dose of nicotine (30-60 milligrams).
  • E-cigarette liquids may remain on surfaces long after the user has left. This includes clothes, furniture, and other surfaces.

E-Cigarettes and cessation.

  • Although often promoted as smoking cessation aids, these devices are NOT regulated by the Food and Drug Administration (FDA) as such.
  • One study found that callers to tobacco quitline services who used e-cigarettes were less likely to be tobacco free 7-months later than those who did not use e-cigarettes. This could show that e-cigarettes are not an effective cessation tool.
