So I was vaping with my Da Vinci (the old style that looks like a walkie talkie) like normal, probably used it 100 times with no problem, when out of no where I'm tasting a nasty fine powder in my mouth. I wipe my tongue off with my finger and its covered in very fine vaped bud! I check my screens and they aren't that dirty and intact. I haven't used it since because I have no idea how much of that shit went in my lungs because it was pretty subtle and I only noticed it because of the taste. Anyone have this kind of problem? At this point I'm ready to toss this thing out because I don't know if its safe.
