Tobacco is scary, that is true. But fear without information is just anxiety — and anxiety has never made anyone quit for good. This category takes the opposite bet: explaining precisely what cigarettes do to your body, without serving you photos of black lungs.
You will find here the 16 cancers linked to tobacco (yes, 16, not just lung cancer), the COPD that has been quietly eating away at smokers for twenty years, the cardiovascular risk that doubles from a single cigarette a day, and all the lesser-known effects: osteoporosis, diabetes, blindness, deafness, slow wound healing. With dated numbers, reliable sources, and good news every time: your body recovers once the cigarette is gone. Often quickly. Faster than you think.
