Yes the dried marijuana will absorb the moisture thats stored in any plant matter when you put them in a jar together.

I have experimented with this before(lemons and oranges), and found that i prefer the taste of the plain weed to the "flavored" weed. Plus it somewhat made the "dried" weed a little more moist to the touch.

so i would say go ahead and experiment with it if you want, it wont rally hurt your weed unless you put too much too much peel in which could cause your weed to mold, and i wouldnt reccomend apple skin either(it gets all brown and nasty).

Good luck.
