I was never a menthol smoker. But having tried a lot of different flavors I still haven't found the one. So after a long debate I decided to get so tobacco flavors, plus some menthol flavoring to added to stuff. How much do you usually add (menthol) before it is over powering. Just ask cause it is due to arrive today. I plan on mixing it in a 6ml bottle so I don't waste a big bottle of anything. Thanks for your help
