Nicotine salts occur naturally in tobacco.
Nicotine salt is a much more stable compound than freebase, but less fickle. Salts requires more heat to volatilize to allow it to be inhaled, which is considered to be a less productive delivery system.
Nicotine salts have a much smoother throat hit when compared to freebase nicotine, which allows users to use higher levels of nicotine, without discomfort.
A good example of this is with the e-juice formulated by Juul. Juul uses nicotine salts derived directly from tobacco leaves. Their e-juice nicotine strength is 50mg , but due to the lower voltage of their device and the smoother throat hit of salts, the throat hit won’t feel anything like 50mg. The user will still get a quick and very strong nicotine buzz, without having to constantly pull on the device. Vaping one Juul pod with 50mg nicotine content is the equivalent of one pack of cigarettes.
Normally what DIY’ers and e-juice manufacturers use is a free compound version of nicotine, or a freebase.
Freebase sounds bad because it’s often associated with the word “freebase cocaine,” but in this case, freebase only means that it’s in its purest form.
First a little science…
Nicotine itself is a base and is not very potent in the body until protons are removed. Nicotine absorbs protons which results in the nicotine molecules becoming ions. Ions don’t move across organic membranes very well so they are less likely to affect the body. For nicotine to become potent, it needs to be converted into a “freebase” form.
Freebase nicotine is the form that tobacco companies use and what most e-juice companies use.
