Smoking also causes pollution, and pollution is very bad. If you smoke, you will speed up the progress of air pollution. Air pollution will eventually cause you, your family and your friends to die. Do you want that? When you smoke, the chemicals in cigarettes go up into the gases in the atmosphere. This weakens the atmosphere so more heat comes in. If people keep smoking, people will die.
Lastly, smoking is terrible for the people surrounding the smoker. Once when I was five, I was walking on the street and someone was smoking. When I walked by him, his cigarette gave me a burn! The worst thing is that cigarette smoke can kill newborns! Secondhand smoke is unfair to all the people who chose not to smoke.
In conclusion, smoking is bad for your health, it causes pollution to the environment, and it is terrible for the surrounding people. It really should be illegal.
