I want to invent healthy cigarette
There are a great number of people who smoke around us, including women and men, even some students. As we all know, a cigarette can contain plenty of toxic materials which are not only harmful to themselves, but also to others. Therefore,I think it is necessary to invent healthy cigarette. If people use it when they want to smoke, it can be used to reduce the bad influence which is caused by the real cigarette.
For our beautiful future and human beings, healthy cigarette should be made.
When I grow up, I want to be an inventor. Healthy cigarette will be my first invention.
