Smoking cigarettes is still very popular among teenagers.
Do people really endanger their lives just to look 'cool'? Perhaps cigarettes are something that makes you more adult? Or maybe those who smoke are the immature ones?
one in eight of you said you were addicted to smoking.

I'm a smoker, but thanks to Newsround your coverage, I haven't smoked in two days, my mum says that if I make it to the end of the month then she'll raise my pocket money. Thanks Newsround!

You should be allowed to choose whether you smoke or not, adults shouldn't criticise kids for smoking when they smoke themselves.

It's OK to smoke just as long as you can control it and not smoke around other people.

You want to ruin your life? Then by all means, smoke.

Smoking is a disgrace to the human race. If are you smoking, you are kiling yourself!
Hamed, 12, Bradford
I started smoking when I was 12, I've gave up two months ago, it was one of the hardest things I've ever done. The best way to quit is not to start.
Jonathan, 16, Turriff
My friend smokes because she grew up with it being normal. Educate the parents!

If you smoke your clothes smell, your breath smells, your teeth and fingernails go yellow and you put other people around you at risk. I don't think that makes you very attractive, do you?

I am a smoker myself and I don't want to quit. Some of you may say it's selfish but it isn't. It is up to us to smoke. It's our lives and we can chose!

Smoking is a really bad thing. Everyone thinks it's cool to smoke but it isn't. At the moment my mate needs help how to stop smoking.
Sarah, 16, Isleworth
People who smoke are not only risking their own lives, they are disturbing other people around them. I'm never going to smoke.
Simon, 11, Bexhill
I think smoking is disgusting. People smoke in the toilets at school and the smoke gives me a cough. I don't see how frying your lungs can make you cool.
Harriet, 13, London
Cigarettes should be declared an illegal drug and its production should be banned. That is the only way to stop people from smoking. After all does not smoking cause more deaths than drug use?
Matt, 15, Ann Abour, USA
I think smoking makes me look really cool and grown up. Since I started smoking I've found it easier to snog girls because I look more mature.

Teenargers are allowed to smoke in UK? Here in Aermica, you aren't allowed to buy cigarettes until you're 18. It's a disgusting habit! It makes your lungs black and makes all the healthy cells die.
Jenny, 14, California
Smoking is disgusting! Whenever I walk past someone who smokes, I try to cough as loudly as I can.
Sara, 14 High Wycombe
I know what smoking does to your body, but if somebody decides to smoke it is their choice and no-one can stop them.

Smoking is really insane. Why are drugs like cannabis and ecstacy illegal? Because they kill you! Doesn't smoking kill you? Why isn't it illegal? Smoking just gives you enough time to grow up, study at university, have a family and then when you die of cancer, you're ruining more lives than just your own.
Sarah, 13, Inverness
I am doing a school project on smoking and from what research I have found I am never smoking. There is too much risk.
Katie, 12, Preston
I smoke now. "Passive" smoking, but not for the image, I get depressed and it calms me down.
Edd, 15, Fareham
People who smoke are selfish and inconsiderate. Just because they want to shorten their lives doesn't mean that people who don't smoke want to as well. I feel that smoking in public places should be illegal. I also think that the prices should go up and if people smoke in public places they should be fined.
Alison, 15, Warrington
I used to smoke until I found out that both of my Grandads died of cancer. My mum said that she didn't want to watch me die. so if I can stop smoking you can.
Jennifer, 11, Guilford
I think smoking is great! I smoke a lot and it is wicked!
Michelle, 9, London
My best-friend smokes and she is really trying to quit. She wants to get a nicotine patch or the nicotine gum but they won't let her buy it because of her age. I think this is not fair as a lot of under age teens smoke. How are they going to quit?
Frances, 15, Norwich
It should be illegal to smoke in public places, then more people will cut down. The prices should go up as well and if people still want to waste money on killing themselves, let them.
James, 13, Goffs Oak
People who smoke are not immature. It's their decision, people should respect that. I am a smoker myself and I have been since I was 11. It gives me a more mature feeling.
Andrea, 15, Runcorn
People who smoke are stupid and don't deserve help to quit. After all we don't have a National Don't Punch Yourself Day.
