With the help of Dr. Hays, director of the Nicotine Dependence Center at Mayo Clinic, and a makeup artist, BuzzFeed aged three smokers to show the physical effects of a continued smoking habit.
"The skin is more affected because of exposure to the smoke. It causes excessive wrinkles around the mouth and creases between the nose and the mouth," said Hays.
"There's also a loss of underlying tissue. So, the face becomes more saggy or more deeply wrinkled," said Hays.
"You also get higher risk of periodontal disease, and tooth loss," said Hays.
Meredith worried that the physical effects only scratched the surface of the damage she was doing to her body.
And according to Hays, "The most important things are what happens to the organs internally."
"The most common conditions that occur are chronic lung disease, emphysema, pulmonary disease (now the third leading cause of death in the U.S.). Secondly, cardiovascular disease. So, heart attacks and strokes are more common in smokers than non-smokers. And then of course cancer. Especially cancers of the mouth, throat, and lungs," said Hays.
