You should never start smoking but if you already started you should stop now.  One danger of smoking I learned in health class is that you can get lung cancer from it.  Another that I learned is that cholesterol forms blood clots in you veins.  In my poster I try to tell people that smoking is a terrible thing for you.  The grave represents that when you smoke you can die from it.  The pack of cigarettes with the "no" symbol on it shows that you shouldn't start smoking.  That is how I feel about smoking.
