No, you haven't smoked too much; this water bong really does change colors when you are using it! The change is triggered by the change in temperature. Here's a recommendation: When you are smoking with a buddy, do not tell them that you have a color-changing bong. At first, they may not notice that the color has changed at all. Then you will notice that they keep looking at the bong again and again. Ask them what is up, and they'll say something like 'Wasn't this blue, or did I just smoke too much?' This is where you TELL THEM NOTHING. Insist that the color never changed.
