Vape Town Blogs & Vaping Guides, Tips & Safety Advice

When moving from smoking to vaping, new vapers can often feel like something is missing and the vape they are using is not quite hitting the sweet spot. Maybe the throat hit you are getting is not quite right or the nic cravings are still there after each inhale. If so the root of the issue is most probably the nicotine type you are using, not necessarily the device you are using.

There is a distinct difference between nicotine salt e-liquid and traditional freebase e-liquids, a much bigger differential than most vapers realise. Our guide explains exactly what each nicotine type does, who it may suit and which products be that freebase e-liquid or nicotine salts stocked at Vape Town will get you to the right choice faster.

Quick Takeaways

Key Insight	Explanation
Nicotine salts absorb faster	Nic salts reach the bloodstream more quickly than freebase, closely mimicking the nicotine hit from a cigarette.
Freebase is harsher at high strengths	Above 12mg, freebase nicotine causes significant throat irritation that most users find unpleasant in a pod or pen device.
Nic salts suit low-power devices	Nicotine salts work best in pod kits and MTL devices. High-wattage sub-ohm kits will over-deliver nicotine dangerously fast.
Freebase suits cloud chasers and DTL vapers	Direct-to-lung devices and sub-ohm tanks pair with lower-strength freebase liquids for satisfying, flavour-rich vaping.
UK TPD caps nic salt strength at 20mg	All nicotine salts sold by Vape Town comply with UK TPD regulations, capping concentration at 20mg per ml.
Heavy smokers generally do better on nic salts	If you smoked 15 or more cigarettes per day, a 20mg nic salt is statistically more likely to satisfy cravings than a 12mg freebase.
Flavour expression differs between types	Freebase liquids often carry more pronounced, complex flavour profiles. Nic salts can taste slightly smoother and sweeter at equivalent strength.

What Is Freebase Nicotine?

Freebase nicotine is the purest form of nicotine used in e-liquids. Developed by researchers Philip Morris in the 1960s to increase cigarette potency, it exists in a chemically unbound state. That free-floating molecular structure means it vaporises readily at lower temperatures, making it ideal for the wide range of wattages used across sub-ohm tanks and direct-to-lung devices.

In practice, freebase nicotine is alkaline. The higher the concentration, the harsher the throat hit. A 3mg freebase e-liquid in a high-wattage device can feel completely smooth. That same alkalinity at 18mg in a low-wattage pod will feel like inhaling sandpaper. This is not a quality problem. It is chemistry working exactly as intended.

Most of the classic shortfill e-liquids you see at Vape Town are designed for freebase use. They come in high VG ratios (typically 70VG/30PG or higher) to produce the vapour volume that DTL devices require.

What Are Nicotine Salts?

Nicotine salts are created by combining freebase nicotine with benzoic acid. This chemical reaction lowers the pH of the nicotine compound, which does two important things. It makes higher nicotine concentrations significantly smoother to inhale, and it accelerates the rate at which nicotine enters the bloodstream.

A study referenced by Public Health England (now UKHSA) found that nicotine delivery speed is a primary factor in craving satisfaction. Nic salts replicate that rapid spike more closely than freebase at equivalent concentrations. For anyone switching from cigarettes, that speed matters enormously in those first few weeks.

"The bioavailability of nicotine from e-cigarettes varies substantially by device and liquid formulation. Nicotine salt formulations consistently demonstrate faster peak plasma nicotine levels compared with freebase equivalents." - UK Health Security Agency (UKHSA) evidence review on vaping and nicotine delivery.

Brands like Lost Mary and Hayati have built their entire disposable and Prefilled vape kits product lines around nic salt formulas, which is a large part of why those products became so dominant with former smokers in the UK. At Vape Town, you will find dedicated nic salt e-liquids from these brands designed specifically for pod systems like the OXVA Xlim and Vaporesso XROS series.

Pro tip: If you are buying nic salts to use in a refillable pod kit, look for liquids with a 50VG/50PG or higher PG ratio. Higher PG carries flavour more efficiently and wicks better in the tighter coils that MTL pod devices use.

Nic Salts vs Freebase: Key Differences

Throat Hit and Smoothness

This is the most immediately noticeable difference. Freebase nicotine at 12mg or above produces a strong throat hit that some ex-smokers enjoy but many find overwhelming on modern low-resistance coils. Nicotine salts at 20mg in a pod kit feel noticeably smoother because the benzoic acid lowers the pH and reduces that harsh alkaline sensation.

A common mistake is assuming a harsher hit means stronger satisfaction. It does not. Nic salts at 20mg will satisfy cravings more effectively than freebase at 18mg because the nicotine absorbs faster, not because it hits harder in the throat.

Nicotine Absorption Speed

The data consistently shows that nic salt formulations reach peak blood nicotine levels faster than freebase at the same concentration. For a heavy smoker stepping down from 20 cigarettes a day, that speed difference is the deciding factor in whether vaping actually replaces the cigarette or merely supplements it.

Freebase nicotine absorbs more slowly, which can leave experienced smokers vaping continuously to chase a satisfaction level the liquid type cannot efficiently deliver. This leads to overconsumption and often causes people to incorrectly conclude that vaping does not work for them.

Flavour Character

Freebase liquids, particularly high-VG shortfills, tend to produce more open, complex flavour profiles. The large vapour cloud carries more flavour compounds. Nic salts, by contrast, often taste slightly cleaner and more direct. The lower vapour volume in MTL vape pod kit means less flavour diffusion, so the liquid needs to be well-formulated to compensate. Brands like Hayati and Lost Mary invest heavily in their salt nic flavour development, and it shows.

Which Devices Work With Each Type?

Device compatibility is non-negotiable. Using the wrong nicotine type in the wrong device is not just ineffective, it can be genuinely unpleasant or, at high wattages, result in nicotine overconsumption. The rule is straightforward: nic salts go in low-power MTL and pod devices, freebase goes in high-wattage sub-ohm and DTL devices.

Pod Kits and MTL Devices for Nicotine Salts

The OXVA Xlim Series, Vaporesso XROS 6, and similar pod kits operate between 8 and 18 watts. At these power levels, a 20mg nic salt delivers nicotine efficiently without flooding the system. These devices typically use coils above 0.8 ohm, which restricts vapour production and suits the MTL (mouth-to-lung) inhale style most smokers naturally use.

Vape Town stocks a wide range of compatible pod kits from Vaporesso and OXVA specifically suited for nic salt use. If you are new to vaping, starting with one of these kits paired with a 20mg nic salt is the approach most likely to replicate the cigarette experience closely enough to stick with it.

Sub-Ohm Tanks and DTL Kits for Freebase

Devices like the Vaporesso Gen series running at 40 to 80 watts require freebase nicotine at 3mg to 6mg. At these power levels, a 20mg nic salt would deliver nicotine at a rate that causes nausea and dizziness. High-VG freebase shortfills are designed for this environment, providing satisfying vapour volume and flavour without overwhelming the user.

Choosing the Right Nicotine Strength

Strength selection is where most newcomers make their first significant error. They either choose too low a strength (because they do not want to be seen as heavily dependent on nicotine) or too high (because they assume more is always better). Neither approach works.

Strength Guide for Former Smokers

Use this as a starting framework. If you smoked fewer than 10 cigarettes per day, a 10mg nic salt in a pod kit or a 6mg freebase in a low-wattage pen device will typically suffice. If you smoked 10 to 20 cigarettes per day, start at 20mg nic salt. If you smoked more than 20 cigarettes per day or were on high-tar cigarettes, 20mg nic salt is the correct starting point and you should not go lower until you have fully transitioned.

The NHS Stop Smoking guidance supports starting at a nicotine level that satisfies, rather than gradually reducing from day one. Unsatisfied cravings are the primary driver of relapse back to smoking.

Pro tip: Do not drop your nicotine strength until you have gone at least two consecutive weeks without craving a cigarette at your current level. Reducing too early is the single most common reason people relapse during the first three months of switching.

Best Use Cases for Each Nicotine Type

Neither nicotine type is universally superior. The right answer depends entirely on your smoking history, the device you are using, and what you want from your vaping experience.

Choose Nicotine Salts If You

Are you a current or recent smoker making the switch, prefer MTL inhale style, use a pod kit or low-wattage pen device, want faster craving relief, or dislike harsh throat sensations at higher nicotine strengths. The nic salts vs freebase debate resolves quickly for this group. Nic salts win on almost every measure for the typical former smoker profile.

Choose Freebase Nicotine If You

Have already been vaping for several months and want to step down your nicotine intake, enjoy DTL vaping with large cloud production, use a sub-ohm tank or high-wattage mod, or are interested in exploring complex flavour shortfills. Experienced vapers who no longer need rapid craving satisfaction will find freebase gives them more flexibility in device choice and flavour range.

Side-by-Side Comparison

The table below compares nicotine salts and freebase nicotine across the factors that actually matter when choosing your e-liquid. This is based on how these products perform in real-world use, not theoretical chemistry.

UK Legal Strength Limit	20mg per ml (TPD compliant)	20mg per ml (TPD compliant, though rarely sold above 12mg)
Vapour Production	Low to medium	Medium to very high
Ideal User Profile	Recent ex-smokers, MTL vapers	Experienced vapers, cloud enthusiasts, DTL users
Flavour Complexity	Clean and direct	Broader, more layered with high-VG formulas

Frequently Asked Questions

Can I use nicotine salts in any vape device?

No. Nicotine salts should only be used in low-wattage pod kits and MTL pen devices operating below approximately 20 watts. Using nic salts in a sub-ohm or high-wattage device will deliver nicotine far too rapidly and can cause dizziness, nausea, and nicotine overconsumption. Always check your device's recommended wattage and coil resistance before selecting your liquid type.

Are nicotine salts safer than freebase nicotine?

Neither formulation is inherently safer than the other in any meaningful clinical sense. Both are significantly less harmful than combustible tobacco, which is the comparison that matters for most Vape Town customers making the switch from smoking. The UKHSA has maintained for several years that vaping is approximately 95% less harmful than smoking. The benzoic acid used in nic salts is recognised as safe at the concentrations found in e-liquid.

What is the best nicotine salt strength for a pack-a-day smoker?

20mg is the correct starting point for a pack-a-day (approximately 20 cigarettes per day) smoker switching to a pod kit. This is the maximum permitted under UK TPD regulations and provides the fastest craving relief. Once you have been cigarette-free for four to six weeks and are no longer experiencing strong cravings, you can consider stepping down to 10mg.

Why do nic salts feel smoother than freebase at the same strength?

The benzoic acid added to create nicotine salts lowers the pH of the liquid. High-pH (alkaline) compounds cause irritation to the throat and mucous membranes. By reducing the pH, nic salt formulas significantly reduce that irritation, making 20mg feel considerably smoother than 20mg freebase, even though the absolute nicotine content is identical.

Do nicotine salts affect flavour compared to freebase?

Yes, but not dramatically. Nic salts tend to taste slightly cleaner and less bitter than freebase at equivalent strengths because the lower alkalinity reduces the chemical edge that high-strength freebase can produce. However, device type and coil resistance influence flavour perception more than the nicotine formulation itself. A well-made nic salt in a quality pod kit will taste excellent.

Can I mix nic salts and freebase nicotine together?

Technically you can, but there is no good reason to. The two formulations are not chemically incompatible, but mixing them undermines the specific benefits of each. You lose the smoothness advantage of nic salts and the cloud production of freebase without gaining anything meaningful in return. Stick to one type matched to your device.

Is there a nicotine type that helps more with quitting smoking long-term?

The research evidence, including data cited in UKHSA and NHS Stop Smoking guidance, points to the most effective vaping approach being the one the user actually sticks with. For most recent ex-smokers, nic salts in a simple pod kit provide the most cigarette-like experience and therefore the best short-term quit support. Long-term, many vapers naturally migrate toward lower-strength freebase as their nicotine dependence decreases.
