If you’ve recently switched from smoking or are exploring vape options for the first time, one of the most common questions you’ll have is around nicotine strength. And with Lost Mary being one of the most talked-about brands in the UK, it’s only natural to ask how much nicotine you’re actually getting from one of their devices.
Lost Mary has become a familiar name thanks to its bold flavours, smooth hit and no-fuss design. But now that the UK has banned disposable vapes, the conversation has shifted to devices like the BM6000, which is fully legal and built to meet the latest regulations.
This guide covers everything you need to know about nicotine in Lost Mary devices, how it works in the BM6000, and what that means for your daily vape experience.
Understanding nicotine strength
Nicotine strength is measured in milligrams per millilitre, or mg/ml. This tells you how much nicotine is present in each millilitre of e-liquid. In the UK, the maximum allowed by law is 20mg/ml, which is often labelled as 2 percent.
This limit is set by the Tobacco and Related Products Regulations, which apply to all nicotine products sold in the UK. Anything stronger than this isn’t legally allowed to be sold for public use.
Lost Mary, like other compliant brands, sticks to this limit. That means every millilitre of e-liquid in a Lost Mary BM6000 contains 20 milligrams of nicotine. But there’s more to the story than just a number.
The difference between nicotine salt and freebase
Lost Mary uses nicotine salts rather than the traditional freebase nicotine found in older e-liquids. This is an important distinction.
Nicotine salts are absorbed more efficiently by the body, meaning you feel the effects more quickly. They also produce a smoother hit at higher strengths, making them ideal for people who are switching from cigarettes or want a satisfying vape without the harshness.
Even though the strength is capped at 20mg/ml, a nicotine salt vape like the BM6000 can feel much stronger and more satisfying than a standard 20mg freebase vape. This is one of the reasons Lost Mary has built such a loyal following among ex-smokers.
How the BM6000 is different
The BM6000 is Lost Mary’s newest legal model for the UK market. It was introduced in response to the government’s decision to ban disposable vapes, which are no longer allowed to be sold due to environmental concerns and underage use.
Unlike its earlier models, the BM6000 is a rechargeable and refillable closed-pod system. It comes with a prefilled 2ml pod already inside the device, plus a refill bottle containing 10ml of e-liquid. Both the pod and the refill liquid use nicotine salts at 20mg/ml.
This format allows you to refill the same pod multiple times, using the included liquid until it’s finished. The device is then recycled or replaced in line with current regulations. It’s still easy to use but offers far more longevity and flexibility than older single-use versions.

So how much nicotine do you get?
While each millilitre contains 20mg of nicotine, how much you actually absorb depends on how often you vape, how long your puffs are and how much liquid you go through each day.
There is no fixed nicotine dose per puff because usage varies. Some people take short, infrequent puffs. Others vape more consistently throughout the day. The BM6000 is designed to offer a consistent and satisfying nicotine experience regardless of how often you use it.
The included refill bottle means the device lasts longer than a single prefilled pod. This gives you a better vaping experience over time, especially if you're used to relying on disposable vapes before the ban.
How does this compare to smoking?
A typical cigarette delivers about 1 to 1.5 milligrams of nicotine into the body. This means a 20-pack might deliver between 20 and 30 milligrams in total. By comparison, vaping gives you more control over your nicotine intake.
You can take just a few puffs and put the device down. You’re not locked into finishing a whole cigarette, and you’re not inhaling all the other chemicals that come with burning tobacco.
Many ex-smokers find that a 20mg/ml salt nicotine vape gives them the same level of satisfaction without the smoke, smell or lingering aftertaste. The BM6000 is particularly well suited to this, with a mesh coil that delivers clean, strong flavour and a hit that feels consistent from start to finish.
Is it legal in the UK?
Yes. The BM6000 has been specifically developed to meet the UK’s legal requirements following the ban on disposable vapes. The nicotine strength is within the 20mg/ml limit, and the e-liquid is delivered through a refillable pod that holds no more than 2ml at a time.
The refill bottle that comes with the device contains more e-liquid for topping up, but this format is completely legal because it gives users a longer-lasting device without breaching single-use laws.
The BM6000 is also compliant with child-resistant packaging, ingredient labelling and emissions testing, which are all part of the current UK rules.
Can you choose different strengths?
At the moment, the BM6000 is only available in 20mg/ml strength. This makes it suitable for smokers and ex-smokers who are used to getting a stronger nicotine hit. It’s not currently offered in lower strengths, although this may change as the product line develops.
If you feel the strength is too high for your needs, you could vape less frequently or look at refillable devices with adjustable wattage and variable nicotine e-liquids.
What if you’re used to disposables?
If you're switching from older Lost Mary disposables like the BM600 or QM600, the BM6000 is your legal alternative. It delivers the same smooth nicotine hit and flavour intensity, but in a format that lasts longer and meets environmental standards.
You’ll still get the familiar draw and flavour quality, just in a more flexible system. Charging is simple, refilling takes seconds, and the feel of the device is similar to what you already know.

Final thoughts
Lost Mary vapes in the UK, including the BM6000, use 20mg/ml nicotine salt e-liquid. This offers a smooth, satisfying hit that’s designed to meet the needs of adult vapers, particularly those transitioning away from cigarettes. The BM6000 format delivers that experience in a longer-lasting, refillable pod device that complies fully with UK law.
You’re not locked into a single-use device. You get a better vaping experience with more control, less waste and the same flavour you’ve come to expect from one of the UK’s leading vape brands.
