I have a certain E-juice (Cappuccino flavor) that i adore but it causes my tongue to turn brown. I assume it's because of the coloring/dye in the liquid. Funny, the liquid is only a very translucent brown and not real dark. But, if it's coating your tongue then it's coating your lungs. I haven't coughed up any brown stuff but still....I think I'm going to steer towards clear liquids. It may cause me to start DIY on E-juice. But I have a lot of commercial stuff to vape first. 
Anyone else get tongue staining?
Come to think of it, it may not be E-juice at all, but all this tea I have been drinking while vaping. LOL. I'm going to try water for a while and see what happens.
