I was an only menthol smoker that never got into menthol vapes. And I DIY and tried various things. You just have to try it and see if you like it.
You can add menthol to any juice. Buy some menthol crystals and some PG, and a 15ml or 30ml glass bottle with a dropper. Dissolve as much as you can, it takes a few hours and you may need to put the bottle in a hot bath. I think I had to put mine in boiling water.
Then add one or two drops to a 15ml bottle of juice. Just a drop at a time because it is VERY strong. And of course you can buy commercial mentholated juice. I'm just trying to get you into a little DIY through a back door
Thinking about it, rather than trying to make the most concentrated menthol you can, you may just put a few crystals in PG, and then a drop at ta time into a smaller amount of juice, maybe a few ml from a favorite juice so you don't waste it if it isn't what you are looking for. No sense killing a whole bottle of juice in the interests of science.
