I was once a menthol smoker. Newports were my brand. It has been hard finding a "replacement" for that taste. Even though I had "re-branded" years ago to Marlboro Reds, once I started
vaping.....I found myself wanting menthol again.
I made myself a mix using DIYFlavorShacks "Flu Cured Tobacco"( about 15 ml @ 36mg nic) and some NHalers "NuPort" ( about 10ml @ a lower nic level). Filled up the rest of a 30ml bottle by topping off with VG.
It isn't quite "Newport" cause the "FCT" is sweeter ( not sweet....."sweeter", you know what I'm saying......lol

) And the "NuPort" has a great menthol flavor and cooling sensation. Reminded me of Kool Filter Kings.
This may be something you wanna try...........
