Standing up for a cause you believe in can be hard, particularly if it means maybe standing up to adults!

But that's exactly what these pupils did when they decided that they no longer wanted to allow them to smoke near their school entrance.

Their head teacher said the students were not happy about passing through the smoke each day, and were concerned about the health issues that second-hand smoke might cause.

While second-hand smoke - which is when you breathe in smoke from cigarettes, but don't smoke directly - is not nearly as dangerous as smoking itself, it can still be damaging to breathe in, in a similar way to pollution.

Those in favour of the ban outside a school, hope it might encourage fewer kids to start smoking if they see people doing it less.

Being around second-hand smoke also exposes someone to the same dangers as the smokers themselves. They inhale the same gases and chemicals.

Children need to be even more careful as their bodies are still developing.

But some people don't agree.

They think smokers should have the freedom to light up wherever they like outside in public. It might also be that they can't give up the habit or don't want to.

Some argue it could be hard to keep an eye on everyone outside the school and they wonder who should be in charge of making sure they follow the rules.
