Here’s another reason to quit smoking: Your joints and discs will thank you. Nicotine from cigarettes, dip, and chewing tobacco cuts down on blood flow to your bones, joints, and to the cushioning discs in your back. It limits how much bone-building calcium your body can take in. It also breaks down estrogen, a hormone you need for bone health. It also slows new growth that thickens bones. All that makes your joints and spine weaker and your bones more likely to break. After surgery, nicotine decreases healing of wounds, increases infection rates, and inhibits bones from healing together. Do your body a favor and avoid products containing nicotine!
