Two Nicotine Forms in E-Liquids: Distinction Between Freebase & Nicotine Salts

When it comes to e-liquids, the choice of nicotine form is a crucial factor that affects the vaping experience. Two primary forms of nicotine are commonly used in freebase nicotine and nicotine salts e-liquids. In this blog post, we will delve into the differences between these two forms, exploring their characteristics, effects, and suitability for different vaping preferences.

Freebase Nicotine

Freebase nicotine is the most common form of nicotine used in traditional e-liquids. It is the purest and simplest form of nicotine, extracted from the tobacco leaf and processed to remove impurities. Freebase nicotine is highly alkaline, which means it has a higher pH level. In e-liquids, freebase nicotine is typically available in higher concentrations, ranging from 3 mg/ml to 24 mg/ml.

Key Features of Freebase Nicotine:

  1. Harshness: Freebase nicotine tends to be harsh on the throat, especially at higher concentrations. This is due to its higher alkalinity and can lead to throat irritation for some users.
  2. Faster Absorption: Compared to nicotine salts, freebase nicotine is absorbed more rapidly by the body. It provides a quicker nicotine hit, resulting in a more immediate satisfaction for vapers.
  3. Higher Vapor Production: E-liquids containing freebase nicotine tend to produce more vapor due to their higher VG (vegetable glycerin) content. This makes it an appealing choice for cloud chasers and those seeking larger vapor clouds.

Nicotine Salts

Nicotine salts, also known as nic salts, are a modified form of nicotine that combines nicotine molecules with an organic acid. This modification reduces the pH level and alters the chemical composition, resulting in a smoother vaping experience. Nicotine salts were initially developed to mimic the nicotine delivery of traditional cigarettes more effectively.

Key Features of Nicotine Salts:

  1. Smoothness: Nicotine salts offer a significantly smoother throat hit compared to freebase nicotine, even at higher concentrations. This makes them more suitable for individuals sensitive to throat irritation.
  2. Higher Nicotine Strengths: Nicotine salts are commonly available in higher nicotine strengths, ranging from 20 mg/ml to 50 mg/ml. This allows users to achieve satisfying nicotine levels without the need for high wattage or excessive vaping.
  3. Slower Absorption: Nicotine salts are absorbed more slowly by the body compared to freebase nicotine. This slower absorption rate results in a more gradual release of nicotine, providing a more prolonged and satisfying vaping experience.
  4. Reduced Vapor Production: E-liquids containing nicotine salts typically have a higher PG (propylene glycol) content, resulting in reduced vapor production. This can be desirable for vapers who prefer a discreet vaping experience or those who prioritize nicotine satisfaction over cloud production.

Choosing the Right Nicotine Form

Selecting the appropriate nicotine form depends on personal preferences, vaping habits, and desired effects. Consider the following factors when making your decision:

  1. Nicotine Strength: If you require higher nicotine levels, nicotine salts may be a suitable choice. They provide a smoother experience even at higher concentrations.
  2. Throat Sensitivity: If you are sensitive to throat irritation or prefer a smoother throat hit, nicotine salts might be preferable due to their reduced harshness.

Vapor Production: If cloud production is a priority, freebase nicotine e-liquids with higher VG content are more suitable. If discreet vaping is preferred, nicotine salts with higher PG content may be preferred.

Composition and Characteristics

The primary distinction between freebase nicotine and nicotine salts lies in their composition and physical characteristics. Freebase nicotine, due to its unprotonated form, has a higher pH level, making it more alkaline. In contrast, nicotine salts have a lower pH level, which leads to a smoother vaping experience and reduced throat irritation. This smoother sensation is often preferred by individuals who have transitioned from smoking to vaping.


Understanding the two nicotine forms in e-liquids: distinction between freebase and nicotine Salts is essential for choosing the right disposable vapes e-liquid for your vaping needs. The choice between these two forms often depends on individual preferences, device compatibility, and nicotine concentration desired. While freebase nicotine offers a stronger throat hit, nicotine salts provide a smoother vaping experience and faster nicotine delivery.
