In the future, like granny said, put it in the freezer IF it's damp. It will prohibit mold from growing, but place it within several freezer bags (about 5 should do). It's better then taking a chance and having mold grow on it. I used to occasionally get damp weed (yeah it sucks, but I didn't have many options =\) that wasn't moldy. Popping it in the freezer helped, even though it supposedly lowers it's potency...which I've yet to notice.
