How Much Nicotine Is in a Vape?

The amount of nicotine in a vape depends on both the nicotine concentration of the e-liquid and the amount of liquid in the product. In the UK, nicotine strength is commonly shown in milligrams per millilitre (mg/ml), and it may also be expressed as a percentage.

These figures can look straightforward, but they describe different things. A label showing 20 mg/ml, for example, describes the concentration of nicotine in the liquid. It does not mean that the user receives 20 mg of nicotine each time they use the vape.

How is nicotine strength measured in vapes?

The most useful figure to look for is mg/ml, meaning milligrams of nicotine per millilitre of e-liquid.

Common examples include:

The percentage and mg/ml figures are therefore two ways of expressing the concentration of nicotine in the liquid.

Under current UK rules, nicotine-containing e-liquid supplied to consumers is limited to a maximum nicotine concentration of 20 mg/ml (2%). The MHRA also states that cartridges and tanks containing nicotine e-liquid are limited to 2 ml, while dedicated nicotine refill containers are limited to 10 ml. See the current MHRA guidance on e-cigarette regulation.

Nicotine strength and total nicotine are not the same thing

It is important to distinguish between nicotine concentration and the total amount of nicotine contained in the liquid.

Consider a 2 ml prefilled pod containing e-liquid at 20 mg/ml.

The calculation is:

20 mg/ml × 2 ml = 40 mg of nicotine in the e-liquid

A 1 ml cartridge containing 20 mg/ml would contain:

20 mg/ml × 1 ml = 20 mg of nicotine in the e-liquid

This tells you how much nicotine is contained in the liquid when measured by its stated concentration and volume.

It does not mean that all of that nicotine is necessarily inhaled or absorbed by the person using the product.

How much nicotine do you actually absorb from a vape?

There is no reliable universal calculation based simply on the number printed on the packaging.

Nicotine delivery and uptake can be influenced by factors including the device, e-liquid formulation and how the product is used. Puff duration, frequency of use and individual behaviour can also vary considerably.

For that reason, the nicotine contained in a pod or cartridge should not be treated as identical to the amount ultimately absorbed by the body.

The NHS describes nicotine as the addictive substance found in cigarettes and nicotine-containing vapes. It also distinguishes the effects of nicotine from the harms caused by burning tobacco. 

How much nicotine is in a 2% vape?

A vape labelled 2% nicotine normally corresponds to 20 mg/ml.

For example:

E-liquid volumeNicotine strengthNicotine contained in the liquid
1 ml 20 mg/ml (2%) 20 mg
2 ml 20 mg/ml (2%) 40 mg
1 ml 12 mg/ml (1.2%) 12 mg
2 ml 12 mg/ml (1.2%) 24 mg

Again, the final column describes the nicotine contained in the e-liquid, not the amount a particular person will absorb.

Why do different vapes have different nicotine amounts?

Vaping products come in different formats and liquid capacities.

A prefilled cartridge might contain 1 ml of e-liquid, while a pod might contain 2 ml. Two products could therefore use exactly the same nicotine concentration but contain different total quantities of nicotine because they hold different amounts of liquid.

Products can also be sold at different nicotine strengths.

This is why it is useful to check both:

  1. Nicotine concentration (mg/ml or %)

  2. E-liquid volume (ml)

Looking at only one of these figures does not give the complete picture.

Do all vapes contain nicotine?

No.

Nicotine-containing and nicotine-free vaping products both exist. A product labelled 0 mg/ml contains no nicotine.

Nicotine-free refers specifically to the nicotine content; it does not mean that the product contains no e-liquid or other ingredients.

For readers specifically comparing products without nicotine, Ezee lists its nicotine-free vape options separately from nicotine-containing variants.

How much nicotine is in a vape compared with a cigarette?

This is where simple calculations can become misleading.

You may see comparisons online that divide the total nicotine in a vape by an assumed amount of nicotine in one cigarette and then claim that a pod is equivalent to a particular number of cigarettes.

That does not provide a reliable like-for-like comparison.

A cigarette and a vape deliver nicotine through different products and patterns of use. The nicotine contained in the original product is also not necessarily the same as the amount ultimately absorbed by the user.

For example, calculating that a 2 ml pod at 20 mg/ml contains 40 mg of nicotine does not establish that using that pod is equivalent to smoking a particular number of cigarettes.

The NHS advises that nicotine intake from vaping can vary according to the product and how it is used. People seeking advice about nicotine use or stopping smoking should use current NHS guidance rather than relying on cigarette-equivalent calculations. 

What is the maximum nicotine strength for vapes in the UK?

For consumer vaping products covered by the Tobacco and Related Products Regulations, nicotine-containing e-liquid is currently restricted to a maximum concentration of 20 mg/ml.

The regulations also impose requirements concerning product capacity, packaging, warnings and notification. Nicotine-containing vaping products must be notified and published through the MHRA before being supplied on the UK market.

These limits apply to consumer vaping products under this regulatory framework. Nicotine-containing products authorised as medicines are regulated differently.

How to read nicotine information on a vape

When checking a nicotine-containing vape or refill, do not look only for a large percentage figure on the front of the packaging.

Check the product information for:

The most important distinction is simple: mg/ml tells you the concentration of nicotine in the liquid. It does not tell you exactly how much nicotine an individual will absorb while vaping.

FAQ

Is 20 mg the same as 2% nicotine?

When referring to e-liquid concentration, 20 mg/ml corresponds to 2% nicotine. Make sure the figure is actually stated as mg/ml, because “20 mg” without a volume describes an amount rather than a concentration.

Is 0 mg vape completely nicotine-free?

A product correctly labelled 0 mg/ml is intended to contain no nicotine. Nicotine-free does not mean ingredient-free; the product can still contain e-liquid formulated without nicotine.

Can I calculate how much nicotine I personally need?

A product label can tell you its nicotine concentration, but this article cannot determine an appropriate personal nicotine dose. If your question relates to nicotine dependence or stopping smoking, use current NHS guidance or speak to an appropriate healthcare or stop-smoking professional.
