You guys have a pretty bad weed culture, from what I've heard. It isn't as developed as the American culture, which has exploded over the past 20 years or so.
About the burning though, that's how you smoke weed man. Each time you hit it, you light it up. In fact, most people will try to snuff it between tokes if they're alone, so it doesn't burn up while they're waiting to hit again. Joints burn through weed quicker than a pipe, but you'll go through lighters quicker with a pipe. On the other side of that though, the pipe is more efficient, and lighters are cheap.
