That is interesting, how in some countries, shisha and hookah mean slightly different things. In the US, for instance, shisha is the actual flavoured tobacco, and hookah is the pipe. For example, here the pipes are called hookahs:

And I've heard in Germany they call the actual smoking pipes shisha.
