The first reason why you shouldn’t smoke is that smoking affects your health. If you smoke, your physical condition will be negatively affected, so it will be very difficult for you to succeed in sports. Also, smoking produces lethal diseases like cancer and reduces the length and quality of your life. Maybe you don’t notice all the physical effects of smoking immediately, but you surely will be sorry one day.
The second reason why you shouldn’t smoke is because of all the money that you spend on it. Maybe you start smoking only when someone offers you a cigarette, but there will be a day when you will feel the need of a cigarette. By this time, you will pay whatever to smoke, and each time you will smoke more, so you will spend more money. All the money you would spend on cigars could have be spent in something better, don’t you think?
The last reason why you shouldn’t smoke is out of respect for the people around you. When you smoke, you not only harm yourself, but you also harm all the people around you. So you mustn’t be selfish; you should at least avoid smoking in front of people who don’t smoke. Also, many people don’t like the cigarette’s smell, so they won’t enjoy your company. Would you like that?
I have said just some reasons of why you shouldn’t smoke, so I hope that now those of you who smoke are able to think a little and try to make a smart decision. In addition to all the reasons I’ve said, I would like you to think about how much you love yourself and then whether you want to continue harming yourself. Think also about all the people who love you, like your family who doesn’t want to see you suffering or sick. If you decide to continue smoking, what a pity. But if you decide to stop smoking, congratulations! Remember that "If you can dream it, you can do it."
