What you mean menthol unflavored, you just using menthol and no tobacco or fruit flavors added? Is it harsh
I mix my own e-liquid. Unflavored is a bit of a misnomer. I don't add any actual flavorings, but PG and VG have a taste of their own. Mine is mostly VG, which has a sweetness to it. That plus a little menthol to give it a light icy tone. It actually tastes pretty good.
I choose to use this for a few reasons:
1. It actually tastes good, and I've never gotten "vaper's tongue" ever with it.
2. It's CHEAP. As in my e-liquid costs me about $75 a year. Between my Provari and my RBA, my yearly cost of vaping is under $100, and that's liquid and new batteries each year.
3. Of all the ingredients in e-liquid, flavorings are the wild card. They are food-safe, but long term effects of inhalation are completely unknown. VG, PG, and nicotine effects are all very well known at this point.
