What is the difference between nicotine salt and freebase?

Freebase nicotine is nicotine in its pure alkaline form. Nicotine salt adds an acid — usually benzoic acid — which lowers the pH. That makes high concentrations far smoother to inhale, which is why almost every high-strength disposable uses salts.

Is nicotine salt stronger than freebase?

Not chemically — the same milligram figure delivers the same nicotine. Salts feel less harsh at high strength, so they are sold at higher concentrations, and they are absorbed somewhat faster. The practical effect is a stronger, quicker hit at the strengths salts are sold in.

Which is better for a disposable vape?

Nicotine salt, and effectively all disposables use it. A 5% freebase liquid in a small device would be unpleasantly harsh. Salts are what made high-strength pocket devices workable.

Does nicotine salt taste different?

Slightly. Salts tend to carry sweeter flavours cleanly and feel smoother on the throat, while freebase gives a more pronounced throat hit and can carry tobacco and menthol profiles more sharply.

Nicotine Salt vs Freebase: What the Difference Actually Is

Nicotine salt is nicotine with an acid added — usually benzoic acid — which lowers the pH and makes high concentrations smooth enough to inhale. Freebase nicotine is the pure alkaline form. That single chemical difference is why a 5% disposable is usable at all.

Why the pH matters

Alkaline freebase nicotine is harsh on the throat, and the harshness scales with concentration. At 50mg/mL a freebase liquid is close to unvapeable for most people. Adding benzoic acid lowers the pH, cuts the throat hit dramatically, and lets the same nicotine be delivered without the burn.

Absorption is also somewhat faster with salts, which is why they feel like they arrive more quickly.

What that means in practice

Salts are used at high strengths — typically 20 to 50mg/mL — in small, low-power devices. Every modern disposable is a salt device.
Freebase is used at low strengths — typically 3 to 12mg/mL — in larger, higher-power refillable setups where a big cloud carries plenty of nicotine at low concentration.

The rule of thumb: small device, high number, salts. Big device, low number, freebase.

The same milligrams are the same nicotine

A common misconception is that salts are "stronger" milligram for milligram. They are not. 50mg/mL is 50mg/mL either way. Salts feel milder, which is exactly why they get sold at concentrations freebase never could — and that is what makes them deliver more in practice.

If the numbers themselves are the confusing part, our guide to what 5% nicotine means covers the conversion.

Flavour

Salts carry sweet and fruit profiles cleanly, because there is less throat harshness competing with the taste. Freebase gives a firmer throat hit that suits tobacco and menthol. Neither is better; they are different experiences.

Which do we sell?

Effectively all of the disposables we stock are nicotine salt devices, which is what the "5%" on the packaging refers to.
