I saw that one girl made clip of her inhaling air only when inhaling smoke of the cigarette and i though it would be fun to try it.

At first it was easy, but with every inhale it got harder and harder. I ended up coughing really bad. I don't know why, but I liked it so much. I am passionate smoker and everything that includes cigarettes makes me satisfied. At the end I talked about that experience and how I would definitely try it again.
