Smoking is one of the worst habits and it has many damages for the smoker and people around him. Smoking is considered one of the killer diseases since it causes lung cancer and stroke. Unfortunately, it's really common in the communities even though people know how bad it is for their health. Smoking contains tobacco and a toxic substance that can kill the one. Smoking can affect badly the person's life and future because when someone starts smoking it will be hard for him to quit smoking and it is just wasting money. People who smoke usually have a bad mood and get angry fast and that causes a lot of problems with family and people. The one can always change his life to the best, but as we know everything will be hard at first so when someone has the resolve, the will and trust in God he can do whatever he wants, it will take some time to quit smoking but when that happens it will be a great achievement.
