I sure hopw someone can help me here. I am trying to play around with flavoring and creating my own liquids. I have 100 mg nicotine and am making 30ml bottles of each flavor. How many drops of the 100mg/ml nicotine should I add to each bottle? Anyone know? I tried to download the calculator scubabatdan posted, but it is not coming up (I am on a Mac). If anyone knows how much, i would greatly appreciate the help! Thanks!
