Quitting smoking is one of the most important things you can do to reduce your risk of cancer. Tobacco smoke contains more than 7000 chemicals, including over 70 carcinogens (chemicals known to cause cancer).
There are immediate health benefits as soon as you quit smoking, even if you already suffer health problems:
- Twelve hours after stopping, almost all nicotine is out of your system with most by-products gone within five days.
- After 24 hours, the level of carbon monoxide in your blood has dropped dramatically, meaning your body can take and use oxygen more efficiently.
- After two days, your senses of taste and smell start to return.
- After two months, blood flow to your hands and feet improves.
- After one year, your risk of heart disease rapidly drops
- After 10 years, your risk of lung cancer is halved.
Many smokers need to practise quitting several times before they give up for good. Keep trying. Practice helps you plan what to do the next time you get an urge to smoke.
