Why You Shouldn't Smoke!!

I listened to the radio from the ESL. It was talking about the disadvantages of smoking, and why the smoker smokes again and again. Smoking is usually linked to heart disease, and it also leads to many kinds of cancer. WHO estimates that five million people a year died from the effects of smoking, and WHO also says that it will kill more than eight million people a year by 2020. The major substance in cigarettes that makes people addicted to it is nicotine; it forces the person to keep smoking. Anyway, it is better not to start smoking.
