Why do people smoke cigarettes?

My first cigarette at aged fourteen nearly made me vomit but I did turn green anyway.

The ONLY reason I smoked,and continued smoking cigarettes was because at Grammar school the hard boys,the roughy toughy rebels and all the other juvenile tripe we believed in showed us to be a little bit better then the other goody goodies.

Of course after a while I succumbed to nicoteine addiction.

I was never a hypocrite,always believed it was a totally stupid practice and admitted it to others,but I also think that its every persons right to indulge if they want to.
I gave up several years ago before you ask.
