What changes will your body go through if you smoke continuously for 10 years?

If you smoke every day for 10 years straight, your body will change a lot. When you first smoke, the harmful chemicals in the smoke can make you feel sick. They go into your lungs and make you cough. But, a drug called nicotine also gets into your blood and brain quickly, which can make you feel good.

After just a week of smoking, the tar in the smoke sticks to your teeth and gums. It slowly wears away your tooth enamel, making your teeth yellow and causing cavities. The smoke also irritates the inside of your mouth, which can lead to mouth sores over time.

A month in, your brain starts to depend on nicotine. It makes you feel good, so you want to keep smoking. But your body tries to get rid of the smoke by itself, to keep you healthy.

After a year, you might smoke so much that your body can't keep up. Bad stuff from the smoke gets deep into your lungs, covering the tiny hair-like parts that help clean your lungs. This makes them less able to work, and your lungs start to get darker.

Five years of smoking, and the bad stuff in the smoke builds up in your lungs. It clogs up the air sacs and stops oxygen from getting into your blood. You might start coughing a lot and have trouble breathing.

Nicotine also makes your blood vessels narrow, and your blood can get sticky. This can cause blood clots, which can lead to heart and brain problems.

After 10 years, your lungs are covered in dark spots from the tar. This can damage the DNA in your cells, making them go wrong and spread to other parts of your body, increasing your risk of cancer. Even people who don't smoke can be affected by the smoke you breathe out.

So, for your health and the health of your family, consider quitting smoking right now.
