I do not regularly vape, but I have had a juul for when i'm tripping sack or really high because the buzz is awesome. Unfortunately, the juul pods are 5% nic and I don't feel a buzz anymore. I met a guy who had 12% nicotine juice he bought online somewhere, and I was soaring(sourin?) off one hit. When I looked online no juice companies have a nicotine percentage, just by mg. I do not know how that works, is there a way to calculate a percentage? I have no way of comparing because there is unit size differences.
% is the same as mg. I think people just confuse it because the % of VG/PG is listed next to Xmg of nicotine.
I've had a few 12mg juices and they are good if you want lots of nicotine. I don't like the low mg juices very much, I usually get 6mg because that's sometimes the highest you can get for certain kinds.
If you order online you can get 12mg which is what I normally do or sometimes even higher like 16mg or more. The highest I have seen is 32mg and when I used to make vape juice I offered it in the range of 0-32
If you don't really care about flavor and just want a good hit you should check out nic salts.
