01772 230513Are Lost Mary Vapes Safe
What UK health bodies and regulators actually say about vaping safety, how genuine Lost Mary products are regulated, and why counterfeit devices are the bigger risk.
No vaping product, including Lost Mary, can honestly be called "safe" in an absolute sense - that's not how UK health bodies describe any vape, and we won't either. What the evidence does show is that genuine, MHRA-notified nicotine vapes are substantially less harmful than smoking, though not risk-free, and their long-term effects still aren't fully known. Lost Mary's products, when genuine and bought from a registered UK retailer, fall within that same regulated framework.
There's a second, separate risk that matters just as much: counterfeit and non-compliant Lost Mary products. These bypass UK safety regulation entirely, and Trading Standards data shows they're a growing problem specifically for this brand. This guide covers what NHS, Cancer Research UK, ASH and GOV.UK evidence actually says about vaping generally, how genuine Lost Mary products are regulated, and how to tell a real one from a fake.

Quick Answer
Genuine, UK-regulated Lost Mary vapes are not risk-free, but current evidence indicates they carry a small fraction of the health risk of smoking. They should only be used by adult smokers trying to stop or stay smokefree, never by non-smokers or under-18s. Separately, counterfeit Lost Mary products carry additional, avoidable risks because they skip UK safety checks entirely - authenticity is arguably the bigger practical safety question for this specific brand.
What UK Health Bodies Actually Say About Vaping
- Less harmful than smoking, not harmless. The NHS states that vapes are thought to be less harmful than smoking tobacco, but they aren't risk-free, and it will be some time before studies can show their full long-term impact.
- A 2022 independent expert review, published on GOV.UK as "Nicotine vaping in England: 2022 evidence update," found that in the short and medium term, vaping poses a small fraction of the risks of smoking.
- Cancer Research UK notes that e-cigarettes don't contain tobacco or most of the toxic chemicals found in cigarette smoke, but vapes haven't been around long enough to be certain about long-term effects.
- Nicotine is addictive in vapes just as it is in cigarettes, and people who smoke can become similarly dependent through vaping.
- Non-smokers and under-18s should not vape, according to the NHS and Cancer Research UK. Vaping is positioned specifically as a quit-smoking tool for adult smokers, not a general-use product.
- No vape is currently licensed as a stop-smoking medicine in the UK, so vapes aren't available on NHS prescription, though some local Stop Smoking Services offer free vape starter kits as part of a wider quit programme.
How Genuine Lost Mary Products Are Regulated in the UK
- MHRA notification. Every legal vaping product sold in the UK must be notified to the Medicines and Healthcare products Regulatory Agency, with a full ingredient listing submitted before it can go on sale.
- ECID registration. Notified products are assigned an ECID (European Community Identification) number by the MHRA for regulatory tracking.
- Nicotine strength cap. UK-legal e-liquid is capped at 20mg/ml nicotine strength.
- Pod and tank capacity cap. Under the UK's Tobacco and Related Products Regulations (the UK's version of the TPD), nicotine-containing e-liquid in a pod or tank is capped at 2ml.
- Sale restrictions. It's illegal to sell vapes to, or buy them for, anyone under 18.
- The Tobacco and Vapes Act 2026, which received Royal Assent in April 2026, adds a licensing scheme for retailers and further controls on vape advertising, flavours and packaging, tightening the regulatory framework Lost Mary and every other legal brand operates within.
The Bigger Risk: Counterfeit Lost Mary Products
Lost Mary is one of the UK's most counterfeited vape brands, alongside Elf Bar and Geek Bar. Trading Standards data shows the scale of the problem:
- Over 1.19 million illegal vapes were confiscated by UK Trading Standards between 2023 and 2024.
- Seizures increased by 59% year-on-year during that period, with nearly 300,000 vapes confiscated in a single quarter.
- Some raids have found devices with nicotine strengths far above the UK's 20mg/ml legal limit.
- Lost Mary itself has issued a public warning to retailers about a rise in counterfeit products, stating they "do not meet the rigorous quality and safety standards of genuine products" and can contain substandard components.
Counterfeit and grey-market vapes skip MHRA notification entirely, which means the nicotine strength on the label isn't verified, the ingredients haven't been checked, and the battery and coil components may be substandard - a genuine fire and health risk that has nothing to do with vaping itself and everything to do with buying an unregulated product.
How to Check a Lost Mary Product Is Genuine
- Check the holographic label and QR code on the side of the box, and verify it on Lost Mary's official verification page.
- Buy from a registered UK retailer with a verifiable business address, rather than marketplace listings, social media sellers, or unofficial resellers - these have been repeatedly flagged by Trading Standards for counterfeit stock.
- Be suspicious of prices well below the standard UK market rate. Genuine, compliant supply chains have a realistic cost floor that counterfeits undercut.
- Look for a nicotine warning label covering a proper portion of the box, correct 2ml pod/tank capacity information, and a maximum strength of 20mg.
- Watch for warning signs during use: an unusual taste, crackling sounds, or a burnt plastic smell can indicate a counterfeit or faulty device.
- Report suspected counterfeits to Lost Mary directly or via the MHRA's Yellow Card scheme, which collects consumer reports on suspected unsafe or non-compliant vaping products.
Who Shouldn't Vape at All
Vaping is positioned by UK health guidance as a tool for adult smokers, not a general-use product. Non-smokers, under-18s, and anyone who has never smoked shouldn't start vaping. If you're pregnant and want to quit smoking, or you're unsure whether vaping is right for your situation, speak to a GP rather than making that decision alone - the NHS notes that switching completely from smoking to vaping can reduce risk for both a pregnant person and their baby compared with continuing to smoke, but this is a conversation to have with a healthcare professional, not a general recommendation.
Frequently Asked Questions
No vaping product is risk-free, and no UK health body describes any vape that way. Genuine, MHRA-notified Lost Mary products are regulated and considered substantially less harmful than smoking, but not harmless.
A widely cited estimate from a 2015 Public Health England-commissioned review suggested vaping is around 95% less harmful than smoking. It's still referenced, but current NHS and Cancer Research UK materials tend to use more general language like "far less harmful" rather than restating that precise figure, since it was based on an expert panel estimate rather than a single definitive study.
Check the holographic label and QR code against Lost Mary's official verification page, and confirm you bought it from a registered UK retailer rather than an unofficial marketplace seller.
Stop using it, report it to Lost Mary or via the MHRA's Yellow Card scheme, and seek a refund from the retailer you bought it from.
No. UK health guidance is consistent that non-smokers and under-18s should not vape - vapes are intended as a tool for adult smokers who want to stop smoking or stay smokefree.
