In this case, you can make your cake and smoke it too. This ashtray cake, made by Natasha of Nevie-Pie Cakes, is completely edible (outside of the glass ashtray on top). The piece was created for a "hen party" -- a term used for bachelorette parties in the UK.

If you want to recreate this cake, I might suggest a little alteration. Place a few real cigarette butts along the sugary ones and watch as your friends go to town. For added realism to this "Night Out" theme, spill some Captian Mo' on top of it and a few crushed cans of Bud. Hey, go big or go home.
