Answer: I will explain to the child the harm caused by tobacco and help him to give up the habit, and inform his parents and teacher.
What I will do: I will talk to him politely and without scolding, show him pictures and information about the diseases caused by tobacco, and tell him about the law banning tobacco sale to minors. I will keep him busy in games, hobbies and studies, encourage him to take help from a doctor or a de-addiction centre, and inform his parents and teachers so that they also support him.
Why: tobacco contains nicotine, which is habit-forming, and cancer-causing substances. It causes cancer of the mouth, throat and lungs, gum disease, ulcers, high blood pressure and heart disease, and it wastes money and spoils studies. The habit is very difficult to leave once it is formed, so it must be stopped early.
