The benefits of quitting smoking have been widely disseminated in public health campaigns of recent decades - a far cry from the advertising campaigns that featured doctors as ambassadors of smoking in the early 1900s. Nevertheless, the benefits of quitting smoking are now clear and smoking as a cultural norm is quickly becoming a fact of history. For those who have not yet kicked the habit, the immediate benefits of doing so might be enough to encourage you to put the cigarettes down:
- After 12 hours, almost all nicotine will be out of your system.
- After 24 hours, the level of carbon monoxide in your blood will drop dramatically and you will have more oxygen in your bloodstream.
- Within 1 month, your blood pressure returns to its normal level and your immune system begins to show signs of recovery.
- After 2 months, your lungs will no longer be producing extra phlegm caused by smoking.
- After 1 year, your risk of dying of heart disease is half of what it would have been if you kept smoking
