At the end of the day, anyone who's been vaping for a while knows the drill: you grab your go-to disposable, take a puff, and boom—it either glides down smooth or it hacks at your throat like you've swallowed crushed glass. If you’ve been wondering “why does my vape hurt my throat” with the Lost Mary, you’re not alone. This isn’t some “it’s just you” scenario; plenty of seasoned vapers have flagged Lost Mary’s disposables, especially the BM600 and QM600 models, as a bit on the harsh side.
Why Does My Vape Hurt My Throat?
Ever wonder why your vape sometimes feels like it’s doing more damage than good? The common culprit here is the nicotine formulation used and the device’s coil technology. Let me break it down:
- Nicotine Salt (Nic Salt): This form of nicotine is smoother and absorbed quicker than freebase nicotine, which most traditional e-liquids contain. Coil Type: Mesh coils are your pal for an even, consistent heat and better flavour delivery without unnecessarily harsh hits.
Loosely put, if your disposable vape is harsh on your throat, it’s either packing too much nic salt strength or uses a less friendly coil design.
Lost Mary: The Reigning King of Disposable Vapes?
Lost Mary’s Made-in-China BM600 and QM600 disposables have absolutely smashed the market across the UK. You can usually pick one up for around £4.99, making them a popular choice for budget-conscious vapers hunting for decent performance. They lean heavily into high nicotine salt strengths — usually between 20mg and 50mg — to mimic cigarette throat hits for those switching over.

Problem is, a lot of users report a throat hit so intense that it borders on painful, especially if they’re not seasoned cloud chasers. The BM600 and QM600 aren’t really designed for those wanting a “smooth disposable vape”. Instead, they’re out to replicate the cigarette buzz, which isn’t everyone's cup of tea.
You know what really annoys me? The lack of consistency in puff count claims. Some Lost Mary units promise 600 puffs and then burn through half their charge in a couple of days. This adds to the harshness because you’re forcing the device to work harder—more heat, harsher hits.
The Nic Salt Factor
Nicotine salt is supposed to make things smoother, right? When done properly, yes. But Lost Mary’s high nic salt concentration can actually overwhelm your throat receptors. It’s like trying to chug fuego instead of water.
Here’s the kicker: How your throat responds to nic salt harshness also depends on what strength you’re used to. A 50mg nic salt puff feels like a slap from a brick to an unaccustomed throat but is just “right” for hardened smokers switching over. If you’re new or a casual vaper, it’s brutal.
Hayati Vape: The New Challenger in the UK Arena
If Lost Mary feels like a heavyweight champ throwing punches you can’t take, meet Hayati Vape — the new kid on the block promising a more balanced experience. Hayati’s disposables also hover around the £4.99 mark but lean more heavily into a refined mesh coil system and mid-range nic salt strengths, delivering cleaner hits.
Their secret sauce? Mesh coils. Unlike traditional wire coils, mesh gives you a larger surface area, heating the e-liquid more evenly and gently. This translates to fuller flavour without the scratch on your throat.
So, what’s the verdict? If you’re fed up with that harsh feeling from Lost Mary but don’t want to ditch disposables entirely, Hayati offers a notable upgrade in smoothness without sacrificing nicotine satisfaction.

Elf Bar: The Veteran’s Take
Don’t count out Elf Bar just yet. They may not have the flashy buzz Lost Mary enjoys right now, but their reputation as one https://www.otsnews.co.uk/hayati-vape-going-toe-to-toe-with-lost-mary-and-elf-bar-in-the-uk-market/ of the OG disposable vape makers in the UK market holds firm. Known for decent coil tech and reliable flavour hits, Elf Bar takes the middle ground in nic salt concentration — enough to satisfy but not to shred your throat.
If Lost Mary hits like a heavyweight and Hayati’s playing the cruiserweight, Elf Bar might just be the welterweight middle ground you didn’t know you were looking for.
Blue Razz Showdown: Lost Mary vs. Hayati vs. Elf Bar
If you’re a flavour junkie, the Blue Razz flavor comparison between these brands is a good test flight:
Brand Flavour Authenticity Throat Hit Smoothness Price Lost Mary Bright but artificial Heavy, often harsh Low £4.99 Hayati Natural, fruit-forward Moderate, balanced High £4.99 Elf Bar Good, classic Medium Medium £5.50 (approx.)In simple terms, Lost Mary’s Blue Razz is bold but can grate on you. Hayati nails the smooth flavour with a friendly throat hit and better coil tech, while Elf Bar plays it safe but reliably tasty.
You Know What Really Annoys Me? Buying Fakes from Dodgy Corner Shops
This is hardly a revelation, but if you’re wondering why your Lost Mary or Elf Bar feels harsher than mates’ devices, ask yourself where you bought it. Fake or cloned disposables flood the UK market, especially from dodgy corner shops that promise the same puffs for less.
These fakes often cut costs with low-quality e-liquid, subpar coils, and faulty batteries — all resulting in nasty throat burns or leaks that ruin your day (and your jeans). If you want to avoid the harsh throat hit horror show, stick to reputable vendors or official websites. Your lungs — and sanity — will thank you.
Final Thoughts: Smooth Disposable Vape or Nic Salt Harshness?
Wrapping it up, if you ask me, the harshness brewing from your Lost Mary vape mostly boils down to:
High nic salt strength designed for smokers, not cloud novices. Less advanced coil tech causing uneven heat and rough hits. Potential fake products with low-quality parts messing with your experience.
Want a vape that’s kinder on the throat but still packs a punch? Check out Hayati’s mesh coil offerings — they strike a better balance between flavour delivery and smooth hits. Elf Bar remains a safe bet with moderate throat hits and classic flavours if you don’t want to experiment.
In the end, your throat deserves a break from bruising hits. Remember—disposables are meant to be convenient and enjoyable, not a test of pain tolerance. So, next time you ask, “why does my vape hurt my throat,” think about nic salt strength, coil tech, and authenticity before blaming yourself.
Cheers to smoother puffs ahead.
