The smoke from your cigarettes (secondhand smoke) puts your loved ones' health at risk. Even if you try to keep smoke out of your home by smoking outside, you still bring nicotine into your home on your clothing and hands, and in your hair.
When you quit smoking, you reduce all of these risk factors for health problems in your family. You also increase the chance that your children will not smoke or will quit if they already smoke.
