When exploring vaping products, particularly e-liquids, you may come across two types of nicotine: freebase nicotine and nicotine salts (nic salts). Both are widely used, but they behave differently depending on the device, nicotine strength and user preference.
Here’s a straightforward guide to help you understand the key differences.
What Is Freebase Nicotine?
Freebase nicotine is the original form used in early e-liquids. It is produced by chemically altering nicotine to remove its natural salts, creating a purer and more stable form.
This type of nicotine is typically found in lower nicotine strengths and is known for producing a stronger, more noticeable throat sensation when inhaled – particularly at higher strengths.
Freebase nicotine is commonly used in more powerful vaping devices, such as sub-ohm kits, which generate larger clouds and allow for a more customisable vaping experience.
What Are Nicotine Salts?
Nicotine salts, also referred to as nic salts, are a combination of acid with natural nicotine found in tobacco leaves, to lower the pH level. This process results in a smoother vaping experience, even at higher nicotine strengths.
Nic salts are most often used in lower-powered devices like pod systems and starter kits. These setups are designed for ease of use and are commonly chosen by adults making a switch from cigarettes to vaping.
How They Differ in Throat Sensation
One of the main distinctions between freebase and nic salt e-liquids is how they feel when inhaled.
Freebase nicotine tends to deliver a sharper, more noticeable throat hit. This can be preferred by users who are accustomed to a stronger sensation.
Nic salts, in contrast, are known for their smoothness. Even at higher nicotine strengths, the throat sensation tends to remain gentle, making them a popular option for those who find traditional e-liquids too harsh.
Device Compatibility and Usage
Different types of nicotine work best with different devices.
Freebase nicotine is usually vaped using high-powered devices. These are designed to produce large clouds and are often used at lower nicotine strengths. They are more suited to experienced vapers who prefer longer sessions and custom settings.
Nic salts are best suited to lower-powered, mouth-to-lung (MTL) devices such as pod systems. These are compact, easy to use and provide a more discreet vaping experience. They are particularly popular among users who prefer convenience or who are looking for a familiar transition from traditional smoking.
Nicotine Strengths and UK Regulations
In the UK, nicotine-containing e-liquids are regulated under the Tobacco and Related Products Regulations (TRPR). The maximum permitted nicotine strength is 20mg/ml (2%).
Nic salts are most commonly available in strengths of 10mg/ml and 20mg/ml. Freebase nicotine tends to be offered in lower concentrations, such as 3mg/ml or 6mg/ml, although higher strengths do exist within legal limits.
The strength you choose may depend on your preference for throat sensation, the device you’re using, and your previous smoking or vaping habits.
Making the Right Choice
Choosing between freebase nicotine and nic salts is largely down to personal preference and device compatibility.
If you’re using a sub-ohm device, or you prefer a more intense throat feel with a lower nicotine strength, freebase nicotine may suit your needs.
If you’re using a compact pod system and want a smoother experience with higher nicotine content, nic salts may be the better option.
Whichever you choose, it’s important to ensure your vaping setup is suited to the type of e-liquid you’re using. Always follow manufacturer guidelines and purchase from trusted, compliant retailers.
