People searching for Lost Mary safety info usually want straight answers, not marketing. This page covers what's in Lost Mary vapes, what the UK regulations say, and the specific ingredient questions that come up most often.
We sell Lost Mary products at Ecigone, so we're not a neutral source on this. For health guidance, the NHS vaping page has the most up to date UK position. What we can do is tell you exactly what's in the products we stock and how they're regulated.
What's In a Lost Mary Vape?
Every Lost Mary vape sold in the UK contains the same four base ingredients. There's nothing unusual in the mix compared to other UK legal e-liquids.
|
Ingredient |
What It Is |
|
Propylene Glycol (PG) |
Carries the flavour and creates a throat hit. Used in food, medicine, and cosmetics. |
|
Vegetable Glycerine (VG) |
Creates the visible vapour. Also used in food and pharmaceutical products. |
|
Nicotine Salt |
20mg nic salt in all prefilled pods. Lost Mary bottled nic salts come in 10mg and 20mg. |
|
Food Grade Flavourings |
The flavour compounds that create each flavour profile. Vary by flavour. |
That's it. No tobacco, no tar, no carbon monoxide. The e-liquid is heated by a coil to create vapour rather than burned, so there's no combustion involved.
Do Lost Mary Vapes Contain Diacetyl?
No. Diacetyl is banned in e-liquids sold in the UK under TPD (Tobacco Products Directive) regulations. All Lost Mary products sold through UK authorised retailers are TPD compliant and don't contain diacetyl.
Diacetyl is a buttery flavouring compound that was linked to lung problems in factory workers exposed to very high concentrations. It was used in some early US e-liquids years ago but has been banned from UK e-liquids for a long time now.
If you're buying Lost Mary from an authorised UK retailer, diacetyl won't be in the product. Counterfeit vapes from unofficial sources are a different story, and there's no way to know what's in those.
Do Lost Mary Vapes Contain Formaldehyde?
Formaldehyde isn't an ingredient in Lost Mary e-liquid. It can be produced in very small amounts when any e-liquid is heated, but this happens at levels far below what cigarette smoke contains.
The concern around formaldehyde in vaping came from early studies that overheated coils at temperatures no real vaper would use. Under normal use with a functioning coil, formaldehyde production is minimal.
Lost Mary's prefilled pods are sealed and use fixed wattage with no adjustable settings. You can't overheat the coil because there's no way to change the power output. The coil runs at the wattage Lost Mary set it to.
Are Lost Mary Vapes TPD Compliant?
Yes. Every Lost Mary product sold in the UK must meet TPD regulations. Here's what that means in practice:
- 2ml maximum pod capacity (the BM6000 uses a 2ml pod with a separate 10ml reserve container)
- 20mg maximum nicotine strength for prefilled products
- Banned ingredients including diacetyl are not allowed
- Emissions testing before products can be sold in the UK
- Child resistant packaging on all products
- Health warnings on packaging
TPD compliance is checked at the manufacturing and import stage. Products that don't pass don't make it onto UK shelves through legitimate supply chains. This is also why buying from authorised retailers matters. Counterfeit Lost Mary products that skip this process have no guarantee of meeting any safety standard.
Is Lost Mary a Good Vape Brand?
Lost Mary is one of the biggest selling vape brands in the UK. They're made by Shenzhen iMiracle Technology, the same parent company behind Elf Bar. The brand launched with disposable vapes and moved to prefilled pod kits after the UK disposable ban in June 2025.
The current Lost Mary range includes:
- BM600 - approximately 600 puffs per pod, compact size
- BM6000 - approximately 6,000 puffs with reserve container
- Nera 30K - approximately 15,000 puffs per side, dual pod with screen
- 4-in-1 - four prefilled pods in one kit, approximately 2,400 puffs total
- Lost Mary nic salts - bottled e-liquid for refillable pod kits in 10mg and 20mg
Lost Mary's main strength is simplicity. All their prefilled kits are draw activated with no buttons or settings. You slot in a pod and vape. Build quality is consistent and the flavour range is one of the largest in the UK prefilled market.
The main limitation is nicotine choice. Prefilled pods only come in 20mg nic salt. If you want lower strengths or 0mg, a refillable kit with your own nic salt e-liquid gives you more options.
Who Makes Lost Mary Vapes?
Lost Mary is made by Shenzhen iMiracle Technology Co., Ltd, based in Shenzhen, China. They're the same company behind Elf Bar, one of the other top selling vape brands in the UK.
The brand name doesn't have a deep meaning behind it. iMiracle launched Lost Mary as a separate brand to sit alongside Elf Bar in the prefilled and disposable market. Both brands share manufacturing and quality control processes but have different product lines and flavour ranges.
Lost Mary products sold in the UK go through the same TPD notification and testing process as every other legal vape product. They're imported through authorised UK distributors and carry the required regulatory markings on packaging.
How to Spot Fake Lost Mary Vapes
Counterfeit Lost Mary products are common, especially from market stalls, social media sellers, and unverified online shops. Fakes don't go through TPD testing and there's no way to know what ingredients they contain.
Signs of a counterfeit Lost Mary:
- Spelling errors on the packaging or labelling
- Wrong colours on buttons or body compared to official images
- Missing or incorrect QR code (genuine products have a verification code)
- Unusual taste or flavour that doesn't match what you'd expect
- Suspiciously low pricing well below normal retail
- No TPD health warnings on packaging
Lost Mary has a verification tool on their website where you can scan the QR code on genuine products. If you're buying from an authorised UK retailer, counterfeits aren't something you need to worry about.
