It is common knowledge now that smoking is bad for you, but I still hear people wondering exactly how can smoking destroy your lungs.
The real question is how doesn't smoking destroy your lungs? There are thousands of chemicals found in cigarettes and when you drag on a cigarette you are taking them all into your body.
 The lungs function is to take in what you inhale and send it to your bloodstream which sends what you inhale to all of your organs.
This is why smoking not only harms the lungs, it causes major malfunctions throughout the body.
One of the most harmful things you are taking in is tar.
Many people think that when you inhale and then blow the smoke out that most of the substance is exhaled, but actually only about 10% leaves the body.
That means that 90% of what you inhale stays in there! As if having all that stuff in there wasn't bad enough...
when the lungs are clogged with so much tar and other chemicals they are not able to function properly and this causes oxygen to become more difficult for the lungs to send to your body.
When you smoke you are starving your body of oxygen and eventually you will see the health reciprocation.
We've all seen the gruesome pictures of what a tar filled lung looks like, they change from a healthy pink to a dark black and eventually they stop working.
The good news is that the lungs regenerate very quickly and this means that even though smoking does destroy your lungs, by quitting you can return to full health in a relatively short period of time.
