Smoking is a very bad habit overwhelming societies today and harming a wide range of people including kids and yet no one is eager to make a change.
The problem is not just that you will have lung cancer and some other diseases. The problem is that this tiny cigarette is ruling your day, your attention and your mood.
If you are in a meeting for hours, you loose concentration earlier since you want to smoke. That also applies if you are in the hospital, airport and any other place that forbids smoking.
Any smoker will surely taste freedom after quitting and will realize that he was in a very big jail. Always remember that prevention is far better than treatment.
