Well, just ask yourself if smoking is necessary for you as a personal habit or just to gain group agreement among your peers?
Smoking is not good for you...to me, it's just like put your mouth on the exhauster and suck in all the useless air to harm yourself.
Yet, you have to pay at the same time...
So, I just hope you can think twice for you smoke again next time~
I wish you a healthy body and happy life!
