Hi everyone. My mom and I both vape and we live together so we share juices. When we first started we were getting 18mg nicotine and that ended up being way too much nicotine for me and a little to much for her. So we switched to 12mg. Its still to much for me but its maybe a little low for my mom. So I switched to 6mg and its great for me but not for her. We cant afford to buy seperate strengths for every juice. So on My Freedom Smokes website I saw some flavorless nicotine in a pg/vg base. There is a 24, 36, 48, 60 and 100mg nicotine levels in that flavorless stuff. And 100% PG... 75/25.. 50/50.. 25/75... and 100% VG...But before I buy some I need to know what strength to buy and a suggestion on what base % to get. And I know I need some sort of a formula. We dont want to have to add so much of the flavorless nicotine that it will dilute the flavor of the juice too much. I will be buying 6mg nicotine e juice from now on....so I need to know what strength of the flavorless nicotine to buy, the recommended base %, and how much to add to bring up the nicotine level to 12-16mg. And the last thing is there another vendor that would be better or one ya'll have had good success with? So I was wondering if anyone could help me out. If you need any more info just let me know.
