Two types of nicotine, one important difference
If you compare two 20 mg/ml vapes side by side and one feels smooth while the other scratches your throat, the difference is almost certainly the form of nicotine inside (the PG/VG ratio is the other common cause): freebase or nicotine salt. Both are legal in Germany under the EU's 20 mg/ml ceiling, both deliver nicotine, and both appear across our disposable range — but they behave differently in ways that should influence what you buy.
What freebase nicotine is
Freebase nicotine is the traditional form: nicotine in its purest alkaloid state, extracted from tobacco and processed so that no acid is bound to it. It has been the standard in e-liquid for decades.
- Sharper throat hit: freebase nicotine is alkaline (higher pH), and that alkalinity is what creates the familiar scratch at the back of the throat. Ex-smokers often like this — it mimics the sensation of a cigarette.
- Slower absorption: the body absorbs freebase nicotine a little more gradually, which some users experience as a smoother ramp-up rather than an instant hit.
- Harsh at high strengths: above roughly 10–12 mg/ml, the throat hit becomes aggressive for most people — and pushing past it is one of the fastest routes to feeling dizzy from vaping. That is why freebase liquids in pod devices are usually 3, 6 or 12 mg/ml — and why, at the EU cap of 20 mg/ml, freebase vapes feel strong.
What nicotine salt is
The practical consequence for intake is covered in our guide to how much nicotine you actually absorb. Nicotine salt is freebase nicotine combined with a mild acid (usually benzoic acid). The acid lowers the pH, which changes two things at once.
- Much smoother at the same strength: a 20 mg/ml salt vape feels far gentler on the throat than a 20 mg/ml freebase vape. You can comfortably use the legal maximum without the harshness that freebase would deliver.
- Faster, more efficient absorption: the salt form crosses into the bloodstream more readily, so the hit arrives quicker and feels closer to a cigarette's nicotine delivery. This is why salt nicotine dominates modern disposables and pod systems.
- Trade-off in taste: some users report that salts taste slightly flatter than freebase at equal strength, though modern formulations have narrowed this. Our flavour guide matters more for taste than the nicotine form does.
Which one fits which situation
| Situation | Better fit | Why |
|---|---|---|
| Recently switched from cigarettes | Salt, 20 mg/ml | Fast absorption and smooth throat, closest to a cigarette's nicotine delivery |
| Light smoker or social vaper | Salt or freebase, 6–12 mg/ml | Enough to satisfy without overdoing it — see the strength guide |
| Chain-vaping and feeling queasy | Lower strength, either form | Symptom of too much nicotine, not the wrong form |
| Want maximum throat sensation | Freebase, 12–20 mg/ml | The harshness is the feature here |
| Nicotine-free by choice | Neither — 0 mg/ml | Our zero-nicotine guide covers this fully |

Common myths worth clearing up
"Salts are stronger."
No — both are capped at 20 mg/ml in the EU. Salts feel smoother and absorb faster, which can make the same number hit harder in practice. The mg/ml on the box is identical.
"Salts damage coils faster."
Not meaningfully. Coil life depends on the device, the sweetness of the flavouring and usage patterns — not on whether benzoic acid is present.
"Freebase is outdated."
It is simply different. For lower strengths and for users who want that distinctive throat hit, freebase remains the better tool.
What about disposables specifically?
Almost every modern disposable in Germany uses salt nicotine at or near 20 mg/ml, because the smooth throat feel is what makes high-strength liquid usable in a draw-activated device. Freebase disposables exist but are niche. If you are moving between disposables and larger pod systems, assume salt unless the label says otherwise — and expect the transition to feel consistent.
Frequently asked questions
Can I feel the difference between 10 mg salt and 10 mg freebase?
Yes, usually: the freebase will scratch more and satisfy a little slower. At 20 mg/ml the difference is dramatic.
Is nicotine salt more addictive?
The nicotine itself is identical; faster absorption simply delivers it more efficiently. If your goal is reducing nicotine dependence, step down the mg/ml over time rather than switching between forms.
How do I tell which form a product uses?
German-market packaging must list ingredients. "Nicotine salts," "nic benzoate" or "salt nic" on the label means salt; plain "nicotine" with a lower strength (3–12 mg) usually means freebase.
Bottom line: salt nicotine for smoothness and cigarette-like delivery, freebase for throat sensation and lower strengths. Both are capped identically by EU law — the form changes the feel, never the ceiling.
