I like the whole concept and the render itself is really great but to be truthful when I first looked at it I didn't realize it was a cigarette until I read it here from you and then it was a eureka moment for me…I’m sometimes slow that way  ;-). So I would agree that some form of identity would enhance the experience for the undiscerning viewer. Perhaps simply adding the typical filter flecks which are commonly seen on cigarette filters to your texture would do the trick. The smoke meandering from the hypo isn't  a bad idea as well.
