What nicotine strength should you choose for your e-liquid?

Quick answer: there is no universal nicotine strength. The right choice depends on how many cigarettes you smoked before vaping, your device’s power, your inhalation style, and the amount of e-liquid you vape. The more vapor a device produces per puff, the lower the concentration generally used; low-power MTL devices make it easier to use higher concentrations.

The goal is therefore not to choose “the highest” or “the lowest” strength, but a concentration that suits your equipment and needs.

What does a strength in mg/ml mean?

An e-liquid labelled 6 mg/ml contains 6 milligrams of nicotine per milliliter of liquid. In France, the maximum permitted concentration for nicotine-containing e-liquids placed on the market is 20 mg/ml.

The strength shown on the bottle does not directly correspond to the number of cigarettes smoked: absorption depends on the equipment, the way you inhale, and how frequently you use it. Tables such as “X cigarettes = Y mg/ml” should therefore be regarded as approximations, not exact equivalents.

The 4 criteria to consider before choosing your strength

1. How many cigarettes you smoked before vaping

The stronger your dependence on tobacco was, the higher your initial nicotine needs may be. However, the number of cigarettes is only one indicator: the way you smoked, the type of cigarette, and when the urge to smoke occurred also matter.

2. Your inhalation style

With mouth-to-lung inhalation (MTL), the vapor is first held in the mouth and then inhaled. The volume per puff is generally more limited, which often allows the use of higher strengths. With direct-to-lung inhalation (DL), the volume of vapor is much greater, so the concentrations used are generally lower.

3. The power of your vape

A large, high-powered sub-ohm tank does not deliver the same volume of vaporized e-liquid as a small pod. Before changing your strength, check the type of coil and the power actually being used.

4. How frequently you vape

Two users vaping at the same strength may absorb very different amounts if they do not vape at the same frequency. Your choice should therefore be reassessed according to your comfort and actual usage.

How can you tell if the strength you chose is not right for you?

An unsuitable strength may cause discomfort or a persistent urge to smoke. If you need to vape almost continuously without feeling satisfied, your nicotine intake may be insufficient; if every puff feels unpleasant or too intense, the strength, power, or type of e-liquid may not suit you.

When quitting smoking, avoid reducing your nicotine strength too quickly solely to reach 0 mg. If you are unsure, a healthcare professional or smoking-cessation specialist can help you adjust your strategy.

Regular nicotine or nicotine salts: is the strength chosen in the same way?

Both forms require you to take the concentration into account. Nicotine salts often provide a smoother throat hit at a comparable strength, which can make a high concentration less noticeable. This does not mean you should increase the dosage without a reason.

You can compare products currently available from VAPEVO: the Liquideo Darka Bubble Baba E-Liquid 10ml is available in several regular nicotine strengths, while the Fuu Minimal Blue Strawberry Nicotine Salt 10ml illustrates several nicotine salt concentrations.

Another example of regular nicotine: ELiquid France Fruizee Blackcurrant Mango 10ml is also available in several strengths, allowing you to stick with the same flavor while adapting the concentration you choose.

Should you gradually reduce your nicotine strength?

This is not an immediate requirement. For an adult smoker replacing cigarettes with vaping, a strength that is too low can make the transition more difficult. A gradual reduction may be considered once your usage is stable and comfortable, while monitoring whether the urge to smoke returns.

Our Mix N Vape guide also explains how to calculate the nicotine strength when preparing a mix.

FAQ: choosing your nicotine strength

What nicotine strength should you start with?

It depends on your tobacco dependence and your device. A beginner using a small MTL pod does not have the same needs as someone using high-powered equipment for direct-to-lung inhalation. If your goal is to replace cigarettes, choose a strength that is satisfying enough rather than reducing it too quickly.

Can you vape 0 mg straight away?

Yes, if you do not want any nicotine intake, but a dependent adult smoker who switches directly to 0 mg may not meet their needs. The approach should be adapted to the individual.

Is 20 mg/ml very strong?

20 mg/ml is the regulatory limit for nicotine-containing e-liquids sold in France. This concentration is generally associated with low- or moderate-power devices and should not be interpreted independently of the device being used.

Can you mix two nicotine strengths?

Yes, mixing two compatible liquids can produce an intermediate strength, but the calculation must be accurate and the recipes must remain compatible with each other. Use our dosage guide or a suitable calculator to avoid mistakes.

Does the ideal strength change over time?

Yes. Your habits, equipment, and goals may change. Your strength can therefore be reassessed, without systematically seeking the fastest possible reduction.
