Have you ever had this experience while vaping, when suddenly your tongue just can’t tell the flavor of the e-juice? If so, then you have vapers tongue: a vaper loses the ability to taste vape juice suddenly and unexpectedly. Don’t panic! If you unfortunately come across this situation, it's only temporary.
That burnt vape taste is an awful experience in the throat, when instead of tasting a smooth flavorful vapour after a long puff, an awful burnt taste is felt.
