How to Pick the Right Nicotine Strength: A Complete Beginner’s Guide (2026)

Choosing the right nicotine strength can make a major difference to how satisfying and comfortable a vape feels. Too little nicotine may leave a smoker feeling unsatisfied and tempted to smoke again, while too much can feel unpleasant and may cause symptoms such as nausea, dizziness, or headaches.

For adults switching from cigarettes, the right strength usually depends on previous smoking habits, the type of vape device being used, and how frequently the person vapes.

In this beginner-friendly 2026 guide, we explain what nicotine strengths mean, how 5mg, 10mg and 20mg options compare, and how to choose a suitable starting point without simply picking the strongest option available.

Important: Vaping products containing nicotine are intended for adults. Nicotine is addictive. People who do not currently smoke or use nicotine should not start vaping.

What Does Nicotine Strength Mean in Vape Liquid?

Nicotine strength tells you how much nicotine is contained in a particular amount of vape liquid.

In the UK, nicotine concentration is commonly shown in milligrams per millilitre, written as mg/ml.

For example:

• 5mg means approximately 5mg of nicotine per millilitre of liquid.

• 10mg means approximately 10mg per millilitre.

• 20mg means approximately 20mg per millilitre.

Higher numbers mean a stronger nicotine concentration.

However, nicotine strength alone does not determine how much nicotine someone actually consumes. Device power, puff frequency, inhale length and vaping style can all influence nicotine delivery.

When browsing products through vapekituk, it is therefore useful to compare both nicotine strength and the type of device the liquid is designed for.

Quick Nicotine Strength Guide for Beginners

The following table gives a simple starting reference.

These are general guidelines rather than fixed rules.

Two people who smoke the same number of cigarettes may prefer different nicotine levels because cigarette type, inhalation style and nicotine dependence can differ significantly.

What Are Nicotine Salts?

Nic salt vape liquids contain nicotine in a formulation designed to provide a smoother inhale at concentrations that might otherwise feel harsher with traditional freebase nicotine.

Nicotine salts are commonly used in:

• Pod kits

• Low-powered vape kits

• Mouth-to-lung devices

• Prefilled pod systems

They are particularly popular among adults moving away from cigarettes because they can provide a more cigarette-like nicotine experience without requiring a high-powered device.

Nic salts should still be selected carefully. A smoother inhale does not mean the nicotine concentration is weak.

Who Might Choose 5mg E-Liquids?

5mg e-liquids sit at the lower end of common nicotine strengths.

They may suit adults who:

• Previously smoked only occasionally

• Have already reduced their nicotine intake

• Vape frequently but prefer lower nicotine per puff

• Find stronger nicotine concentrations uncomfortable

A lower strength can also be useful for people gradually reducing their nicotine consumption.

However, someone switching from regular cigarette smoking may find 5mg too weak initially. If the nicotine level is insufficient, they may compensate by vaping much more frequently or continue craving cigarettes.

The goal is not automatically to choose the lowest nicotine level. It is to find a strength that adequately replaces the nicotine previously obtained from smoking.

Who Might Choose 10mg E-Liquids?

10mg e-liquids are often considered a middle-ground option.

They may suit light or moderate smokers who want a noticeable nicotine delivery without moving immediately to the maximum commonly available UK strength.

Someone who previously smoked around a moderate number of cigarettes each day may find 10mg a sensible place to begin, especially when using a low-powered pod kit.

The actual experience will still vary by device.

For example, a pod kit with efficient nicotine delivery may feel stronger than another device using the same 10mg concentration.

Who Might Choose 20mg E-Liquids?

20mg e-liquids contain a relatively high nicotine concentration and are commonly found in nicotine salt products and prefilled pods.

In the UK, 20mg/ml is the maximum nicotine concentration permitted for nicotine-containing e-liquid sold to consumers under current vaping regulations.

This strength may be more appropriate for adults with a stronger dependence on cigarettes who find lower concentrations do not adequately control cravings.

It should not automatically be considered the best option for every new vaper.

Someone who previously smoked only a few cigarettes per day could find 20mg unnecessarily strong.

How Does Your Previous Cigarette Use Affect Nicotine Strength?

Your previous smoking habit is one of the most useful starting points when choosing nicotine strength.

A heavier smoker usually has greater nicotine dependence than an occasional smoker. Therefore, switching directly to a very low nicotine concentration may not provide sufficient satisfaction.

However, cigarette count is only part of the picture.

Consider:

• Number of cigarettes smoked each day

• How soon after waking you normally smoked

• Whether you frequently experienced cravings

• Type and strength of cigarettes previously used

• How deeply and frequently you inhaled

Someone who previously smoked immediately after waking may have stronger nicotine dependence than another person smoking the same number of cigarettes later throughout the day.

Does the Vape Device Affect Which Nicotine Strength You Need?

Yes.

Your vape device can significantly influence the most appropriate nicotine concentration.

Low-Powered Pod Kits

Low-powered pod systems are commonly paired with higher-strength nicotine salts because they produce relatively small amounts of vapour per puff.

High-Powered Vape Kits

High-powered devices produce considerably more vapour.

Because more liquid can be vaporised with each puff, lower nicotine strengths are generally used in these systems.

Using a high-strength nicotine liquid in a powerful sub-ohm device may deliver substantially more nicotine than expected.

Always check the manufacturer's device and coil recommendations before selecting your E-liquids.

Signs Your Nicotine Strength May Be Too Low

A nicotine concentration may be too low if you consistently experience:

• Strong cigarette cravings

• Feeling unsatisfied immediately after vaping

• Constant vaping throughout the day

• Difficulty staying away from cigarettes

However, frequent vaping does not automatically mean the nicotine level must be increased. Habit, device performance and vaping technique can also influence usage.

Signs Your Nicotine Strength May Be Too High

Using more nicotine than your body is accustomed to can feel uncomfortable.

Possible signs include:

• Nausea

• Dizziness

• Headache

• Light-headedness

• Feeling unusually uncomfortable after vaping

If this happens, stop using the product and consider a lower nicotine concentration.

Anyone experiencing severe or persistent symptoms should seek medical advice.

Should Beginners Start With 5mg, 10mg or 20mg?

There is no universal nicotine strength that works for every beginner.

A practical approach is:

5mg: Consider if you previously smoked very lightly or are already reducing nicotine.

10mg: Often suitable as a moderate starting point for light-to-moderate smokers.

20mg: May suit adults with stronger nicotine dependence who previously smoked regularly and find lower strengths insufficient.

The objective when switching from cigarettes is usually to use enough nicotine to control smoking cravings without taking more than necessary.

Can You Gradually Reduce Your Nicotine Strength?

Yes.

Some adults eventually reduce nicotine concentration after becoming comfortable using a vape instead of cigarettes.

For example, someone might move from:

20mg → 10mg → 5mg → lower or nicotine-free liquid.

There is no requirement to reduce quickly.

If lowering nicotine causes strong cigarette cravings, remaining temporarily at a more suitable nicotine level may be preferable to returning to smoking.

The NHS also advises people using vaping to stop smoking to choose enough nicotine to manage cravings effectively.

UK Nicotine Strength Regulations

UK vaping products are regulated under tobacco and related-product legislation.

Among other requirements, nicotine-containing refill containers sold to consumers are subject to limits on nicotine concentration and container size.

The maximum permitted nicotine concentration for standard consumer vape liquid is 20mg/ml.

More information on UK vaping and tobacco-product regulations is available from the UK Government:

Because regulations can change, users and retailers should always check current official guidance.

Frequently Asked Questions

What nicotine strength should a beginner use?

It depends primarily on previous smoking habits and the vape device being used. Light smokers may consider lower strengths such as 5mg or 10mg, while people with stronger cigarette dependence may require higher concentrations such as 20mg.

Is 20mg nicotine strong?

Yes. 20mg/ml is a high nicotine concentration and is the maximum generally permitted in consumer nicotine e-liquid under UK regulations.

Is 10mg nicotine good for beginners?

10mg can be a reasonable middle-ground option for some light-to-moderate smokers, particularly when using low-powered pod kits.

Is 5mg nicotine enough?

It may be enough for light smokers, people reducing their nicotine intake or users who vape more frequently. Regular smokers switching from cigarettes may find it insufficient.

Are nicotine salts stronger than normal vape liquid?

Not automatically. Strength depends on the stated nicotine concentration. However, nicotine salts often feel smoother at higher strengths than comparable freebase nicotine liquids.

Should non-smokers use nicotine vapes?

No. People who do not smoke or already use nicotine should not start using nicotine-containing vape products.

Final Thoughts: Choosing the Right Nicotine Strength

Choosing the right nicotine strength is about finding a level that matches your previous nicotine use, device type and individual vaping habits.

Lower strengths such as 5mg may work well for lighter users, while 10mg can provide a middle-ground option. Adults with stronger cigarette dependence may require 20mg initially to control cravings effectively.

Instead of focusing on finding the strongest or weakest liquid, focus on finding a nicotine concentration that feels sufficient without producing unpleasant effects.

For adults switching away from cigarettes, getting nicotine strength right can make the transition significantly easier and reduce the temptation to return to smoking.
