I've got quite few bottles of absolutely terrible e juice laying around that have been bothering for few weeks now. Do I suck it up and just vape them, or throw them away? Theres nothing worse than a nasty vape, and tossing out 40$ worth of juice makes me cringe. I decided to add a few drops of menthol to them and see how they taste....not too bad! I never smoked menthol cigarettes but a little menthol adds a refreshing twist to a tasty juice. A little more menthol can mask a nasty juice too.
