Best used in subohm tanks and direct to lung inhales, freebase e-liquids utilizes a common form of nicotine that is often considered to be the purest form of the substance. Because of its purity, freebase e-liquids are offered in lower and more manageable nicotine strengths, and they will generally offer a more noticeable throat hit.
Originally developed in the 1960s, freebase nicotine served as the go-to nicotine for e-liquids since the advent of vaping. This form of nicotine will generally produce a more pronounced throat hit but will be more potent when heated. Because of this, freebase e-liquids will feature lower nicotine strengths (i.e. 3mg, 6mg, 12mg) making them ideal for direct-to-lung inhales and high power sub-ohm coils.
Freebase Nicotine vs. Nicotine Salt
While the two are variations on a naturally occurring substance, there are fundamental differences between the two. Without getting too technical, the two variations of nicotine differ primarily in their production and their effect on the human body.
Originally developed by Philip Morris in the 1960s, freebase nicotine has been the go-to option for e-juice manufacturers since the beginning of vaping. This form of nicotine has a higher pH level, meaning it will be slightly harsher, but this version is also more potent when heated. Generally speaking, finding e-liquids with freebase nicotine should be easier, considering the prevalent use of the substance across vaping and with the majority of e-liquid manufacturers.
At its core, nicotine salt is composed of the same nicotine found in the natural state within the tobacco leaf. However, nicotine salt is further augmented with benzoic acid, allowing it to be properly vaped and absorbed into the human body. Nicotine salt also offers a more even rate of absorption into the body and can provide a less harsh throat hit, if in lower percentages.
Why Choose Freebase Nicotine
Unlike nicotine salt, freebase nicotine can be used in almost any device and will allow users to exhale larger clouds of vapor. Freebase e-liquids may also be better suited for new vapers who may not enjoy the higher concentration of nicotine used in nicotine salt e-liquids.
