used unmarked postage stamps

Hiya
Wasn't sure where to stick this query.. so thought I'de try here, as I know there are loads of chatterboxes around.
I've received a package and am going to re-use the jiffy bag to send something. The stamp on the jiffy bag is unmarked. Do you reckon it will be okay to not bother buying a new stamp, and simply use the one that's already on the jiffy bag?

It's probably illegal or something but I'd re-use it (although my OH wouldn't - he's far too honest (and rich-lol)

Well, the govenrnment/councils are encouraging us to re-cycle.... there, my conscious is clear... will risk it and re-use the stamp! Thanks for your replies.
