Why smoking is injurius to health and in which of our body smoke is effect.

Cigarettes have multiple dangerous toxins that you ingest when smoking, the tar builds up coatings on your lungs that damage cells, they cannot repair the damage and become leather like and fatty making it harder for your body to process oxygen, cigarettes contain multiple poisons including cyanide that also damage cell structures, but the worst thing is it damages the heart and ventricles, narrowing arteries restricting blood flow. Cigarette smoking is also directly linked to numerous aggressive cancers that thrive due to damaged cell structures. I am a lifelong smoker and cant stop, I wished I had never started, so if you have a choice dont smoke.
