Adrian Spade : I've never understood the use of smoking - even when people say they use it to calm the nerves. My father has been smoking everyday since he was a teen (he's in his late 60's now) and you can't go an hour without him coughing up a storm, and spitting up tar into the sink. That's why when I read comments online from smokers playing the "yolo" excuse and "it's my body" and all that, it made me a little furious. So you want to spend your short life in pain? There is a plethora of healthier ways to cope with stress, there are plenty of chances to escape peer pressure, and there are certainly other ways live that "#coolkid" life, so please stay safe for the sake of yourself and those around you.

Takadatsu : When you are depressed and life it's a pain every single day...death is nothing, smoking is nothing.

Николай Смирнов : Glad i've never started.

score fresh : I think my school should offer nicotene toffee (2 per cigarette) in exchange for cigaretes. A 20p money given for a cigarette box. If course most after school sports won't stop, but 20p is pretty good.
