Smoking can be very harmful to everybody. First, smoking develops cancer, and there is more than 4000 toxic chemicals inside a cigarette. Also, the nicotine inside is very addictive.
Second, smoking is also very harmful to other people. People around a smoker can also smoke by second hand smoking. Also, the government spends thousands of dollars in curing people sick by smoking.
Because of these reasons, I believe we should ban smoking. Thank you.
