Does anyone else get this? I've notice the last few days I've been vaping when I exhale from my nose there are some oily particles (e-juice) and an oily drip as well. It concerns me a bit. I can tell it is e-juice from the feel of it on my fingers. It's thick and sticky like glycerin. It's not just snot or anything. I'm worried the e-juice liquid/oils will build up on my lungs.
