I have a favorite flavor that only comes in a 16mg strength, what I wanted to do was buy some nicotine and strengthen it to 24mg. The 16mg flavor comes in 10ml bottles and I bought three of them. So how much of the flavor and how much nicotine will I need to mix to make it 24mg ? Should I buy 24mg strength nicotine or higher to bring the 16mg flavor up to 24mg ?
