How will smoking tobacco affect me?
Tobacco, from the tobacco plant, releases a mixture of chemicals and tar that are taken into the lungs when you smoke. Not only is smoking addictive, but it temporarily increases the heart rate and blood pressure, which, over time, can cause a heart attack and/or stroke. Fat deposits caused by smoking can narrow and block blood vessels, whilst respiratory illnesses such as emphysema and bronchitis are common. The tar that builds up and coats the lungs can slowly cause cancer.
