By. Erick 2.7.5.
It can hurt you.
Chronic kidney disease, leading to a failure of the kidneys.
I won't waste word limit on bad breath; there's cancers of the lip, tongue, mouth, throat. Much before that, your yellowing teeth might get loose due to receding gums.
The chemicals in your cigarette damage the supply of oxygen to your lungs.
You'll wrinkle faster, your teeth will yellow, you'll lose hair faster all in your mid-thirties.
