I went to grab some PS LBF from my tobacco shelf and noticed that my C&D Afterhours had a white spot in it. I picked up the jar for further inspection, and noticed a larger patch that had mold on it.
I'm assuming that this tobacco is junk now, no saving it, even though there's only two spots with mold.
My real questions are:
1) How does this happen?
2) How can I prevent this in the future?
