Late to the thread, but, yeah - I would totally smoke this. Not mold, imo - Likely micro-crystalline deposits from various compounds or minerals (additives, or sugars, or salts, etc..).
Imo, every smoker should have a either a USB microscope or stereo microscope in their toolkit. It is really easy to identify molds this way. Molds are not crystals and crystals are not molds. They are super cheap.
