Freebase vs Nicotine Salts E-Liquids (also known as vape juice, eJuices, nicotine liquids) typically only contain these four ingredients: vegetable glycerin (VG), propylene glycol (PG), flavoring, and nicotine.
What is Freebase E-Liquid?
Most freebase nicotine extracted directly from tobacco plant, deriving pure nicotine from plant, excluding any other impurity or by-product. This free-form of nicotine leads to unbalanced alkalinity, imparting a stronger throat hit as nicotine concentrations increased. This can felt at higher levels of freebase nicotine, with 3mg leaving a smooth yet tolerable throat hit, while becoming harsher at 6mg, and even more so at 12mg. E-Liquid manufacturers tend to stay within the range of 0mg to 6mg, rarely going to 12mg or 18mg due to the extreme harshness of freebase eJuice and smaller demographics vaping at this level. E-Liquid with 0mg does not contain any trace of nicotine with pure VG/PG and flavoring.
What is Nicotine Salts
Nicotine Salts, or Nic Salts, is a slight alteration to freebase nicotine, with the addition of benzoic acid to help balance the alkalinity levels of freebase nicotine. Typically, this leads to the harshness levels considerably reduced, allowing for a smoother experience despite the higher nicotine concentrations. Nicotine Salts tend to start at 20mg and can reach as high as 59mg, with reduced discomfort in throat hits when vaping on an appropriate lower power vape device such as pod system, thanks to the composition of nic salts and benzoic acid.
Now that you know what each type of nicotine is and it’s characteristics and qualities, we can help find a suitable device for each.
What is Sub-Ohm Salts, or Sub-Ohm Nicotine Salts
Nicotine Salts are typically known to used with lower power, smaller devices but there some exception. Some E-Liquid manufacturers does replicate the nicotine salts formulation for Sub-Ohm use, referring to these E-Liquids as “Sub-Ohm Salts”. You can feel reassure that using Box Mod Kits or higher power devices with these “Sub-Ohm Nicotine Salts” will be okay as they are typically denote in 3mg and 6mg in nicotine strength. The reason for the utilization of Nicotine Salts in this form is to reduce the harsh throat hit of regular free-based forumation, creating a different and usually smoother throat hit than a typical 3mg or 6mg.
Free-Base E-Liquid and Sub-Ohm Device
Freebase E-Liquids are great for sub-ohm devices, or box mod paired bigger atomizers such tanks and RDAs. As freebase nicotine has a lower degree of nicotine concentration, they best used with Sub-Ohm Devices. larger coil, higher power, and lower resistances of sub-ohm devices and tanks allowing for freebase nicotine to be vaporized within juice, delivering a small dose within a large cloud of vapor. These are best for those that prefer performance, outputting substantial clouds. Although plenty of vapor created, nicotine concentration remains fairly low. Freebase eJuice can loaded into a pod system for more discretion, but many pod systems not optimized for freebase eJuice, as lower strength of freebase nicotine cannot be fully vaporized to same capacity sub-ohm devices are capable of.

Nicotine Salts and Pod System
Nicotine salts on the other hand is great for pod systems, utilizing the lower power output, smaller coil, and higher resistance to create discreet clouds of vapor that deliver nicotine salt with much better results. The inclusion of benzoic acid aids in the smoother delivery of nicotine salts, balancing the alkalinity for less of a throat feel. High nicotine strength Nic Salts should never loaded into a sub-ohm device, as stronger vapor output will deliver more nicotine to be absorbed by body, leading to great degree of discomfort.
Some pod systems such as Pod Mods available geared for both nicotine salts and freebase eJuice, depending on the type of coil or pod installed. One simple rule of thumb to follow is nicotine salts belong with higher resistances clocking in at or over 1.0ohm. This allows for a safe and efficient dosing of higher nicotine, allowing nicotine salts to work to their full potential. This ensures safer vaporization and delivery of lower nicotine concentrations within a larger vapor output.
