What Are Nicotine Salts?
Nic salts are behind most of today’s pod systems and many disposables, and they explain why a small, low-power device can use a much higher nicotine strength than a big sub-ohm tank. If you have seen “salt nic” on a label and wondered what it means, this guide is for you.
You will learn what nicotine salts are, how they differ from the freebase nicotine in traditional vape juice, their pros and cons, and how to match them to the right device and strength.
Short version: Nicotine salts are nicotine combined with an acid, which makes high strengths feel smoother. They usually come in 20 to 50 mg and are made for low-power pod systems with coils above 1 ohm. Do not use high-strength salts in a sub-ohm tank.
What nicotine salts are
Freebase nicotine is the form used in most traditional bottled vape juice. It is fairly alkaline, and the higher the strength, the harsher it feels on the throat. That is one reason freebase juice rarely goes above 18 mg, and why sub-ohm vapers usually stick to 3 or 6 mg.
Nicotine salts, or nic salts, are made by combining nicotine with an acid, commonly benzoic acid. The acid lowers the liquid’s pH, and the result feels much smoother to inhale at high strengths. That smoothness is what lets nic salt e-liquids come in strengths that would be uncomfortably harsh as freebase.
Strength is listed in milligrams per milliliter (mg/ml). Some brands use a percentage instead, so 5% means 50 mg/ml. Our guide to nicotine strength has a full conversion table.
Nic salts vs. freebase nicotine
| Nic salts | Freebase nicotine | |
|---|---|---|
| Typical strengths | 20 to 50 mg | 0 to 18 mg |
| Feel at high strength | Smooth | Harsh |
| Devices | Pod systems, disposables, low-power mouth-to-lung kits | Starter kits, mouth-to-lung tanks, sub-ohm tanks, rebuildables |
| Power | Low wattage, coils above 1 ohm | Low to high, depending on the device |
| Typical PG/VG | 50/50 | Anything from high-PG to high-VG |
| Vapor | Modest | Modest to very dense |
In short, salts are built for small devices and higher strengths, while freebase covers everything from mouth-to-lung starter kits to cloud-focused sub-ohm setups at low strengths.
Pros and cons of nic salts
Why vapers like them
- Smoother at high strengths. Salts let you use a higher strength without the rough throat hit freebase would give, which is why they are popular with vapers who want a stronger nicotine level in a small device.
- Small, simple devices. Salts work at low power, so you do not need a big mod or a sub-ohm tank. A compact pod system or a disposable vape is all it takes.
- A bottle goes further. Low-power pods vaporize far less liquid per puff than sub-ohm tanks, so a 30 ml bottle usually lasts longer, even if a salt costs a little more per bottle.
- Low-key clouds. Small devices at low power make modest vapor, which is handy when you want to be discreet. See our guide to stealth vaping.
What to watch out for
- A lot of nicotine. Salt strengths are high, and nicotine is addictive. If you do not already use much nicotine, a high-strength salt can be far more than you want. Start at the lower end of the range, and if you feel lightheaded or nauseous or get a headache, stop and switch to a lower strength.
- Fewer device options. Salts are built for pods and low-power mouth-to-lung devices, so there is less room to experiment with tanks, coils and big clouds.
- Not for sub-ohm tanks. In a high-powered sub-ohm tank, a high-strength salt is harsh and delivers far too much nicotine per puff.
- Handle with care. Nicotine e-liquid can be harmful if swallowed, and higher strengths mean more nicotine in every bottle. Keep bottles capped and out of reach of children and pets.
How to vape nicotine salts
Pick the right device
Use a device made for nic salts. Most pod systems and low-power mouth-to-lung kits are, and the usual sign is a coil rated above 1.0 ohm running at low wattage. Many pod systems are draw-activated with nothing to adjust, which makes them an easy place to start. If the numbers are new to you, read what ohms mean in vaping.
Choose a strength
Nic salts commonly run from about 20 to 50 mg, and the top of that range is very strong. Match the strength to how much nicotine you already use, and if you are unsure, choose the lower one.
Vape them the right way
- Take slow, gentle mouth-to-lung puffs rather than long direct-to-lung draws.
- Prime new coils or pods and give them a few minutes to soak before your first puff.
- Keep the pod topped up so the wick never runs dry. A burnt taste means it is time for a fresh coil or pod, so check when to change your coils.
- Most salt e-liquids are 50/50 blends, and our guide to 50/50 e-liquid explains why that ratio suits pods.
Trying nic salts
Flavor matters as much with salts as with any vape juice, so start with the families you already enjoy, whether that is fruit, menthol or tobacco. Our guide to choosing the right e-liquid can help you narrow it down.
If you would rather not hunt for salt nic flavors one bottle at a time, the Zamplebox Club‘s Salt Nic Box sends four 30 ml bottles at 18 mg or higher, chosen for your flavor profile, for $39.99 a month. You can preview the box, swap any bottle before it ships, and skip, pause or cancel anytime.
Common questions
Are nic salts stronger than regular vape juice?
They usually come in higher strengths, commonly 20 to 50 mg, compared with 0 to 18 mg for freebase juice. The salt form makes those strengths feel smoother.
Can I use nic salts in a sub-ohm tank?
Not high-strength salts. In a sub-ohm tank they are harsh and deliver far too much nicotine per puff. Use low-strength freebase juice instead.
What nic salt strength should I choose?
It depends on how much nicotine you already use. If you are unsure, start at the lower end of the range. Our nicotine strength guide explains the options.
Will nic salts work in any pod?
Most pod systems are designed for them, but check your device’s manual for the recommended coil resistance and e-liquid type.
