So I had this great idea in my never ending search for the perfect Salem ultra light ( which, after almost 3 months, I don't really remember what they tasted like). I was scoping out different liquids and I saw menthol drops. Perfect. I can buy some cowboy carts and add menthol. I learned the hard way, you don't need more than a drop. Wow. Talk about mouthwash! It worked fairly well with one drop. It did not work so well with several drops. Really the best combo I have found so far is wow cowboy menthol juice and adding premium smilin menthol. My experiment since we are out of wow cm wasn't so good.
