I suggest getting the menthol drops mentioned above. Then you can turn anything into a Menthol. I just add 15 drops of Menthol to 30 Ml of anything, but you could go higher or lower on the drops to suit your taste.
I don't particulary like the flavors labeled "Menthol" . They don't taste like tobacco to me.
My favorites are Kent and, believe it or not, RY4, both with menthol added.
