While you may get a buzz from the "fluff" out of the vaporizer, it certainly isn't what it was fresh.

Either you're not efficiently vaporizing the weed the first time in the VAP or your not getting much from the residual. Bottom line, there is a finite amount of buzz in your budz.

I save mine as well and then pack a bunch into the Volcano cup with some ground coffee beans or something else and run it a second time. The taste definetaly degrades the second time around and there is much less intensity.
