smoking is harmful?there's no benifit in it?

Smoking is really a addiction and not easy to quit all of sudden. But good thing is there are many rehabilition center for helping to get rid of these habits. Try them and make a great change in your life.

I think something is beneficial ! but what it is I don't understand.

There are benefits in smoking, but not enough to say that it's good. Like: just because a dish has vegetables, it doesn't mean it's healthful. Smoking relaxes the person smoking (but spreads damaging second hand smoke to passers by). Also, it is said to help the brain function more quickly - however these few benefits could not overcome its damaging effects: such as inhaling toxins, bad breath, lung cancer, spreading second hand smoke, etc. Thanks for the response on my discussion!

Let's me ask you,can you tell me the time of smoked meet puts is longer or the fresh meat puts is longer? that's a joke!

Well, actually it has a benefit. It gives you (smokers) the benefit of a happy life. Plain and simple. Why should you not smoke? Live how you want to live right? Besides there are many deaths more worse than those that you get from smoking.
