Why do you smoke?

First time I done it was to look cool. I can admit that. My friend smoked and tried to get me to smoke and she was successful.

I then gave it up cold turkey.

Then I picked it back up again about a year or two ago. The reason why is because I don't feel like I can inhale enough. I don't feel like the oxygen fills up my body and I feel like a part is trapped off. Don't get me wrong I could breathe perfectly normal but it felt weird. So I picked up smoking again because it gave that sharpish feeling that I can only describe as cutting in to the trapped part I couldn't get air in to previously.

Again, that's simply how it felt, I doubt I couldn't get oxygen in me properly. :)
