i would like to uninvent cigarettes, because it is not useful and addictive. The disadvantages of smoking is so much more than the advantages. you could say that its stupid if one smokes because not only that they effect themselves but they effect other innocent people around them. The best thing that you could do is just help people understand what they are doing to themselves and what are the consequence of smoking and just support them in staying clean and environmental. Smoking effects both the people and the environment. We are responsible to what happens to our children and our enviroment.
