i dont know of any cutting too much
as far as i understand
eliquid consists of nicotine (pure) and propelyne glycol
some have citric acid or glycerin/glycerol depending on the maker
if youwant to take 48 mg down to 18mg then you would just cut it with the corresponging amount of Propelyne glycol
(you can
vape non nic liquids of just PG mixed with VG - i recommend using about 30% VG for more vapor production.)
so lets do some math - you have 500ML - wow can i have some lol?
as far as ive read the nic is usually measured per ML so each ML has 48 you could cut it per ml or all at once, you'll need alot of PG tho
basically 48/18 = 2.6
so basically if we do ML
1ml of 48 + 1ml PG = 2ml of 24mg
so 1 ml of + 1.6ml pg = 2.6ml of 18mg
someone please correct me if im wrong, im a bit hazy headed from smoking osmething we arent allowed totalk about in this forum
