Hi everyone. I started vaping 2 weeks ago, i first got some closed pod system which wasn’t enough for me so i bought some MTL starter kits. At first i didn’t know what nicotine level i needed so i bought a whole lot of 3mg and 6mg juices. I now know that i need beetween 12 and 16mg. So i wanted to know if i could use some nic shots to turn those 3 and 6mg nic juices into 12mg for exemple. If not is there another way or have i bought these for nothing ? Thx for your time and answers. Peace from France.
