Stop The Stores From Selling Cigarettes!!!

My petitions overview is to stop people from selling cigarettes. If people sell cigarettes than other people smoke them. Now in days millions and millions of people smoke and it becomes a habit of smoking. Smoking kills lots of people because the nicotine causes lung cancer and much more deseases. My dad smokes and he has been smoking for 15 or more years now, I try to tell him to stop but he is so used to smoking that he cant stop. Thats why I am trying to stop stores from selling cigarettes. Well you know that your throat is the color pink right, well when you smoke and the longer you have been smoking the nicotine goes into your body and yellow liquid comes into your throat which is the nicotine and thats what causes lung desease, because it also goes to your lungs and every other part of your body. So please help stop smoking because it doesnt  just hurt the smoker but everyone and everything around the smoker (and causes pollution)!!! SO SIGN NOW PLEASE!!!
