Shortfill E-Liquids

Adding an 18mg bottle of freebase nicotine to a 50ml capacity bottle of e-liquid will mix to a 3mg/0.3%. To mix to a 6mg, you’ll need double the amount of nicotine. Some shortfill bottles have enough space for two nic shots, otherwise you'll need to decant some liquid first to allow for the extra bottle of nicotine, then mix. By the same principle, if you want a very light nicotine level, just put in half the nic shot to your liquid.

When it comes to nicotine shots, you have a couple of options. The first is freebase nicotine, the most common form of nicotine found in e-liquid, it’s more affordable and has more of a throat hit when used in higher doses. The other format you can use is nicotine salts, a lower pH form that can be used in higher doses and vaporises at lower temperatures. Depending on what kind of device you have and your nicotine level needs one may suit you more than the other. Those using pod kits and lower powered devices can benefit from nic salts to get a high dose. For Sub Ohm devices you’re better off with freebase nicotine at a lower level as high powered devices deliver nicotine in higher concentrations than plus ohm kits.
