A Brainteaser [EvolutionBlog]

Here’s a brainteaser for you. I’m interested to know what you all think of it:

A group of smokers had twenty-five cigarette butts in an ashtray. Each butt still contained a small amount of usable tobacco. The smokers knew that any five butts contained enough tobacco to make one new cigarette. How many new cigarettes could they make with the available butts?

For various reasons, I’m especially interested to know if you find the wording to be vague in any important way.
