We need to make you aware that there is not simply one type of bong anymore, there are so many different types out there with small additions added to pipes that are coming in totally different shapes that would not look anything like a bong. A bong shop like http://www.herbtools.com/ is a great example of the different sorts of products currently being sold out there.
While some of these are better for health than others, overall they might not be quite as safe as once thought, so do not think now you are a proud owner of one that you can smoke all day every day without causing damage.
