Tobacco - Frequently Asked Questions

What is in tobacco?

  • The burning of tobacco produces smoke that contains more than 4000 chemicals including nicotine, tar, and carbon monoxide.
  • Tar is made up of thousands of chemicals, 50 of which are known to cause cancer.
  • Carbon monoxide is a poisonous gas formed when tobacco is burned. Carbon monoxide lowers the amount of oxygen carried in your blood, and therefore limits how much oxygen your body gets.
  • Nicotine is an addictive drug that affects the brain and nervous system. It acts as a stimulant and increases heart rate and breathing.
  • At higher doses nicotine is a deadly poison that has been used as an insecticide.
