Smoking is bad for health. Everybody knows it, but when you are smokers especially heavy smokers, it is not an easy thing to stop. Some people can make it,but other keep smoking even though they try so hard to stop that bad habit. Some people socially smoking and I think those who socially smoking are unique people because usually when a person start to smoke, he/she want to try and try again until the he/she become an addict to cigarette.
A lot of my friends are smokers, they smoke a lot until they can build the cigarette tower shown below. Have a nice day and healthy life.
