In the world of vaping, a small revolution is changing the game! Indeed, after years of hegemony, <\/span>classic nicotine<\/b>, also called freebase nicotine, is gradually giving way to <\/span>nicotine salts<\/b> in e-liquids for electronic cigarettes. Let’s be clear, both substances serve the same purpose: your smoking cessation. However, they have <\/span>many differences<\/b>, starting from their chemical nature to their noticeably distinct effects.<\/span><\/p>\n

So that you can fully understand what differs between the two substances, we are focusing on several points of comparison to consider in order to choose the best solution for you. <\/span>Absorption speed<\/b>, <\/span>compatible hardware<\/b>, <\/span>“hit”<\/b> (sensation in the throat), <\/span>vaper profile<\/b>\u2026 Everything is scrutinized for a pleasant vaping experience and, above all, a successful cessation.<\/span><\/p>\n

Understanding Nicotine in Vaping<\/h2>\n

Let’s start at the beginning: the role of nicotine in vaping. It is an alkaloid naturally present in the tobacco leaf and is also one of the substances that creates dependence. For a <\/span>gradual cessation<\/b> and a gentle one, it is added in liquid form to e-liquids<\/a>. Its role is twofold.<\/span><\/p>\n

On one hand, nicotine allows former smokers not to feel the withdrawal associated with quitting traditional cigarettes from a purely chemical point of view. On the other hand, it simulates the sensation of the larynx contracting as the smoke passes, which is called the <\/span>“throat hit”<\/b>. The way it is processed and formulated will, in fact, directly influence the vaping experience. This is where the differences between nicotine salt and classic nicotine come into play.<\/span><\/p>\n

What is Classic Nicotine?<\/h2>\n

Classic nicotine<\/b>, also known as freebase nicotine<\/b> or purified nicotine, is the oldest and most widespread form in e-liquids for electronic cigarettes. Present in the tobacco leaf, it is extracted and then purified to obtain a pharmaceutical-grade product.<\/span><\/p>\n

Chemically, it has a basic (alkaline) pH<\/b>. It is precisely this high pH that results in a very pronounced “hit”<\/b> in the throat, a sensation that often becomes irritating<\/b> at high dosages. Note that it is also this form of freebase nicotine that has historically been used in nicotine replacement therapies like patches or gums.<\/span><\/p>\n

 <\/p>\n

What is Nicotine Salt?<\/h2>\n

Nicotine salt<\/b><\/a>, on the other hand, is the form closest… to its natural state<\/b> in the tobacco leaf. To be used in an e-liquid, it is combined with acids (like benzoic acid or lactic acid).<\/span><\/p>\n

These additions lower its pH<\/b>, making it more acidic and therefore much smoother to inhale<\/b>, even at high concentrations. It is this characteristic that allows for faster<\/b> and more efficient absorption<\/b> by the body. The vapor very faithfully reproduces the sensation provided by a tobacco cigarette.<\/span><\/p>\n

 <\/p>\n

The Differences Between Nicotine Salt and Classic Nicotine<\/h2>\n

Let’s now look in detail at the concrete nuances between nicotine salt and classic nicotine when they are put into practice in an electronic cigarette.<\/span><\/p>\n

Throat Sensations: The Famous \u201cHit\u201d<\/h3>\n

Classic nicotine<\/b> causes a powerful<\/b>, dry, and very noticeable “hit”<\/b>. The higher the level you choose, the more it increases. This solution is for you if you like this very distinct sensation. However, it can cause quite a bit of irritation and untimely coughing, which is bothersome for many vapers.<\/span><\/p>\n

As you’ve understood, with nicotine salts<\/b>, the “hit” is very smooth<\/b>, sometimes almost non-existent. This makes it an ideal solution for the most sensitive throats, allowing one to vape high levels, <\/b>for example, 20 mg\/mL, without any discomfort.<\/span><\/p>\n

Absorption Time by the Body<\/h3>\n

In terms of absorption, that of classic nicotine<\/b> is slow and gradual<\/b>. As a result, your peak satisfaction is reached after several puffs, in 5-10 minutes.<\/span><\/p>\n

In contrast, nicotine salt<\/b> offers you fast and almost instantaneous absorption<\/b>. You reach the peak in a few seconds, simulating the efficiency of a tobacco cigarette. This is ideal, especially, for calming a pressing craving.<\/span><\/p>\n

Available Nicotine Levels<\/h3>\n

Regarding the available levels in each of these substances, this also differs. For a very gradual and, above all, adjustable reduction, classic nicotine<\/b> offers a wide range of possibilities: 0, 3, 6, 11, 12, 16, 18, or even mg\/mL.<\/span><\/p>\n

For nicotine salt<\/b>, it’s a different story. It mainly exists in high levels<\/b> which are intended for a more radical stop to traditional cigarettes. Note that in France and Europe, the Tobacco Products Directive (TPD) mainly authorizes levels of 10 and 20 mg\/mL<\/b>.<\/span><\/p>\n

Device Compatibility<\/h3>\n

The form of nicotine in your e-liquid will directly influence your choice of hardware. Thus, while classic nicotine is versatile, this is not at all the case for nicotine salts.<\/span><\/p>\n

Freebase nicotine<\/b> can therefore be used with all types of electronic cigarettes<\/b>, from the simplest (pods) to the most powerful (sub-ohm clearomizers, rebuildable atomizers). In contrast, nicotine salt<\/b> must be vaped with low-power<\/b> hardware (generally below 20 watts) and high-resistance coils<\/b> (above 0.8 ohm).<\/span><\/p>\n

The reason for this distinction is simple: using nicotine salts with a powerful electronic cigarette would deliver too large a dose of nicotine too quickly, and you would risk a nicotine overdose<\/b>, which is not only unpleasant but also very dangerous.<\/span><\/p>\n

Addiction and Potential Risks<\/h3>\n

As you know, nicotine is addictive regardless of its form. Nevertheless, there are some nuances to consider depending on the form you choose. The rapid action of nicotine salts<\/b> could hypothetically be more complex to manage and create a fairly strong dependence<\/b>. Classic nicotine<\/b> acts more slowly and could promote a more controlled cessation<\/b>.<\/span><\/p>\n
