-
The Lost Mary 3500 Puffs vape offers an impressive puff capacity and a diverse range of flavours, catering to vapers who enjoy vaping with nic salt.
-
Compliance with UK vaping regulations is critical, as high puff counts may breach legal limits on e-liquid capacity and nicotine levels.

The Lost Mary 3500 Puffs disposable vape is a favourite among vapers for its impressive puff capacity and premium flavour offerings. This device allows users to enjoy up to 3500 puffs, eliminating the need for frequent replacements and providing an extended vaping experience. Many users appreciate the variety of flavours available, with over 22 unique options catering to different tastes.
User satisfaction is high, with many praising the performance and reliability of the Lost Mary 3500 Puffs. The device’s overall performance and ease of use, in addition to the flavours, make it a preferred choice for both new and seasoned vapers. This satisfaction is likely down to the enormous puff quantity - a measure that could indicate the Lost Mary 3500 is illegal in the UK.
High Puff Count
One of the standout features of the Lost Mary 3500 Puffs is its high puff count. Offering approximately 3500 puffs, this device caters to users who prefer extended usage without the hassle of frequent device swaps. The high puff count allows for longer vaping periods, enhancing convenience.
However, some users have reported inconsistencies in the puff count, suggesting that not all devices deliver the promised 3500 puffs. While most users are satisfied with the device’s performance, it’s important to be aware of these potential variations.
This high puff count is indicative of a higher volume of e-liquid than the legal limit of 2ml. A good example of a disposable vape that is meant to contain the legal limit of e-liquid is the Elf Bar 600, with the '600' being an indication of how many puffs a user should expect to get from the device. While there is naturally some variation between users like the size and strength of the inhale, this figure is a good rough indication of how many puffs to expect from these disposable vapes.
The SMOKO VAPE POD and the SMOKO VAPE MAX feature 2ml prefilled pods that attach to rechargeable batteries. We would expect a puff count for the whole pod to be around the 600 mark, as with most legal prefilled vapes, depending on individual usage. The advantages for prefilled options are many, from being able to change flavours at a whim to re-using the battery for months - and both parts can be easily recycled, making it a more sustainable choice.
Long-Lasting Battery Life
The Lost Mary 3500 Puffs features a robust 650 mAh battery, ensuring sufficient power for long vaping sessions. This substantial battery capacity allows for uninterrupted vaping throughout the day, adding to the overall satisfying vaping experience. Users often commend the battery’s longevity, noting that it lasts significantly longer than expected without the need for frequent recharges.
The rechargeable battery allows the Lost Mary 3500 Puffs to ensure the user gets to the last drop of vape juice, where other non-rechargeable disposables could potentially run out of charge before the e-liquid is finished, leaving the user with no option but to move on to their next disposable vape.
While rechargeable disposable vapes may be a step in the right direction for reducing waste, there are still major drawbacks in terms of the lack of recyclability and the lithium going to waste (1) when the device has no e-liquid left in the tank. These sealed units are contributing to increased waste, with an estimated 5 million disposable vapes being thrown away each week in the UK. (2)
This is why, at SMOKO, we favour rechargeable vape batteries that can be used time and time again before they need to be replaced. SMOKO batteries can be recycled at your local battery recycling, and you can recycle your empty SMOKO refills with us for free!
We are particularly pleased with the New VAPE MAX battery life, lasting a whole 2ml pod and then some on a single charge!
Compact Design and Portability
The sleek and compact design makes the Lost Mary 3500 Puffs an ideal choice for portability and convenience. There is no doubt its compact size and slim form make it easy to carry, fitting comfortably in pockets or small bags. Portability allows users to enjoy their vaping experience wherever they go.
Users appreciate the device’s stylish and compact design, blending simplicity with functionality. The anti-stick design enhances usability, making it a practical option for everyday use.
Compare this with the SMOKO E-Cigarette; a cigalike style vape no larger than a traditional cigarette. Not only does this take the place of a tobacco cigarette perfectly - a big help for smokers making the switch - carrying a spare battery and refill doesn't impact the convenience and can ensure you are stocked up to keep vaping on the go.
Both the SMOKO VAPE POD and the VAPE MAX are only slightly bigger than the SMOKO E-Cigarette, making them easy, convenient options to keep you vaping all day.
Diverse Range of Flavours

The Lost Mary 3500 Puffs is known for its diverse flavours, catering to various vaping preferences. From fruity to candy-inspired and menthol to dessert flavours, there is something for everyone. Users often highlight the rich and authentic flavour profiles, enjoying the intense and satisfying taste each puff delivers.
This variety allows vapers to explore and find favourites, making it a versatile choice. Whether you prefer the sweetness of fruits or the indulgence of desserts, this device offers a flavour to suit your palate.
It's important to note that Lost Mary disposable vapes utilise nic salts in their e-liquid. This salt form of nicotine provides a smooth inhale, where devices like the SMOKO VAPE MAX use freebase nicotine, a form which is absorbed in the throat and therefore provides something known as 'throat hit' that many smokers are looking for when they make the switch to vaping, so they can 'feel' the vapour going down.
With nic salt liquids, one study found that they typically contain 3 to 4 times the amount of flavourings used in freebase nicotine liquids (3). This is significant because the flavourings are responsible for some of the volatile compounds produced in the vaping process, potentially indicating that freebase nicotine liquids could be safer than nic salt liquids.
Fruity Flavours
Fruity flavours are among the most popular options for vapers using the Lost Mary 3500 Puffs. Favourites include strawberry ice, watermelon ice, and lemon lime, each providing a refreshing and enjoyable taste experience. Strawberry ice offers a sweet and refreshing experience, a top choice for fruity vape enthusiasts.
Watermelon ice provides a juicy and revitalising flavour, ideal for hot days or a refreshing burst. Lemon lime offers a tangy and zesty taste, both invigorating and satisfying, for citrus lovers.
Candy-Inspired Flavours
Candy-inspired flavours like rainbow candy and fizzy cherry add a playful twist to the vaping experience. Rainbow candy offers a medley of sweet flavours reminiscent of classic candy treats, delighting those with a sweet tooth. Fizzy cherry mimics cherry soda, offering a nostalgic and enjoyable vaping experience.
However, it’s important to note that the UK government has expressed concerns about flavours that appeal to children, such as these candy-inspired options. This concern is one reason behind the upcoming ban on disposable vapes, including those with candy flavours, set to take effect in June 2025. (4)
Menthol and Dessert Flavours
Menthol flavours are ideal for vapers who enjoy a cooling sensation. Options like icy mint and menthol tobacco offer a crisp and refreshing taste, enhancing the vaping experience. These flavours are favoured by those who appreciate menthol’s invigorating effect.
Dessert flavours, on the other hand, cater to those with a sweet tooth. Flavours like vanilla custard, chocolate fudge, and creamy caramel provide a rich and indulgent vaping experience, making each puff a treat. These flavours cater to vapers seeking a decadent and satisfying taste.
SMOKO VAPE Flavours
SMOKO is intended to provide a great option for smokers to help them quit smoking, boasting a range of straightforward flavours including a range of tobacco options, fruits like Raspberry, Cherry and Black Currant, and more rich offerings like Vanilla and Coffee.
User-Friendly Features
Designed with user-friendliness in mind, the Lost Mary 3500 Puffs is a convenient choice for both beginners and experienced vapers. Its lightweight and compact design ensures portability and convenience, easy to carry for vaping on the go. The wide flavour selection and ease of use are often highlighted by users, contributing to its popularity.
The Lost Mary 3500 also features user-friendly mechanisms like draw activation and Type-C charging, enhancing functionality for everyday use.
Draw Activation

A standout feature of the Lost Mary 3500 Puffs is its inhale-activated mechanism. This system allows users to inhale to activate the vape, eliminating buttons and simplifying use. Beginners particularly appreciate this feature as it simplifies vaping compared to button-operated devices.
Users report positive experiences with the draw activation feature, highlighting its simplicity and reliability. This mechanism ensures a seamless and enjoyable experience, making the Lost Mary 3500 Puffs user-friendly.
Disposable vapes aren't the only ones to utilise inhale activation - all SMOKO devices from the SMOKO E-Cigarette Cigalike vape to the SMOKO VAPE POD make use of this technology, eliminating the need for buttons and potential auto-firing and accidental button presses.
Mouth to Lung (MTL) Vaping Style
The Lost Mary 3500 Puffs supports a mouth-to-lung (MTL) vaping style, closely resembling the sensation of smoking traditional cigarettes. This MTL experience makes it easier for smokers to transition to vaping, providing a familiar and satisfying experience. For this reason, SMOKO devices are designed for a mouth to lung vaping style.
Users who switched from smoking often praise the MTL style, noting its effectiveness in replicating the feel of traditional cigarettes.
Type-C Charging
Equipped with a Type-C charging port, the Lost Mary 3500 Puffs facilitates quick and efficient recharging. This modern charging solution ensures the device is always ready for use, enhancing convenience.
Nicotine Free Options
Vapers who are keen to reduce their nicotine intake do have the option of vaping nicotine-free e-liquids. This nicotine free option for Lost Mary 3500 enhances the device’s appeal, especially for those looking to quit smoking and avoid nicotine. It looks like nicotine free options may be able to contain more than the 2ml e-liquid limit for nicotine containing vapes.
Legal Considerations in the UK

UK legality of vapour products like the Lost Mary 3500 Puffs is influenced by regulations on nicotine levels and puff counts. These regulations ensure consumer safety and prevent vaping product misuse. Vapers must understand these legal considerations to ensure compliance and avoid legal issues.
High puff count vapes like the Lost Mary 3500 must adhere to guidelines on e-liquid capacity and nicotine content. While the nicotine free version may not be subject to the 2ml legal limit, the nicotine containing Lost Mary 3500 is likely to be in breach of UK regulations.
Maximum Tank Size
The UK sets a legal limit of 2ml for e-cigarette tank capacity. This regulation, part of the Tobacco Products Directive (TPD) and Tobacco and Related Products Regulations (TRPR), limits the quantity of e-liquid used at one time.
Products like the Lost Mary 3500, claiming thousands of puffs, may breach regulations if exceeding the 2ml e-liquid capacity. Compliance with this regulation is essential for the legality and safety of vaping products.
British American Tobacco (BAT) conducted their own testing on disposable vape products on UK shelves and found that almost all contained more than the legal 2ml limit (x)- with an average overfill of an additional 50%, bringing the total e-liquid in many of the tanks to around 3ml. This is clearly a breach of UK regulations and has contributed to the government decision to ban all disposable vapes as of June 2025.
Puff Limits and Legality
A typical 2ml tank provides approximately 600 puffs (5). Thus, disposable vapes with nicotine and single pods larger than 2ml are illegal in the UK. The Lost Mary 3500 Puffs is meant to comply with these regulations to be legally sold in the UK.
The puff count of the Lost Mary 3500 suggests it does not comply with TPD and TRPR regulations. Nicotine disposable vapes offering far above 600 puffs are likely illegal in the UK, highlighting the importance of adhering to legal requirements.
Where to Buy Lost Mary 3500 Puffs in the UK
Purchasing Lost Mary 3500 Puffs from reputable sources ensures quality and authenticity. The Vape Pack, a leading UK online store for 3500 Puffs Vapes, offers diverse high-quality vaping products and a seamless shopping experience. Sadly, purchasing from established retailers should ensure product compliance with legal regulations, however this was demonstrated not to be the case by the testing conducted by British American Tobacco.

Online Vape Shops
For competitive prices, Vape Superstore specialises in discounted vaping products, including the Lost Mary 3500 Puffs at a good price. Vape Online Store offers free next-day delivery on orders over £40, catering to those needing quick access to vaping supplies.
The great thing about using SMOKO Vapes and E-Cigs is that we are an independent vape store supplying our own product, so when you get in touch with us you are talking to someone with product knowledge instead of a middle-man.
Customer Reviews and Feedback
Customer reviews are crucial for understanding the user experience of the Lost Mary 3500 Puffs vape. Many users consistently praise the flavour satisfaction, highlighting the rich and authentic taste profiles. The impressive battery life also receives positive feedback, enhancing the extended and satisfying vaping experience.
The major issue surrounding the Lost Mary brand is the fact that their vapes allegedly contained illegal levels of e-liquid, and while the Lost Mary 3500 Puffs nicotine free vape may be legal here in the UK, the nicotine-containing version is most certainly illegal. This raises issues of trust as breaches of the UK regulations are a serious infringement that shouldn't be allowed to pass unnoticed. With youth vaping as a rising issue, a driving force behind the disposable vape ban, and generally a bad thing for society, companies that ignore the regulations put in place for the safety of the consumer should be named, shamed and prevented from selling their product.

So why is SMOKO different? Our products use e-liquid made here in the UK, subject to the rules and regulations mentioned above, and are also submitted to the UK's Medicines and Healthcare products Regulatory Agency (MHRA) for approval in every flavour, at every strength. We even fill SMOKO refills here in the UK, too!
SMOKO also has a track record over a decade long. We have been helping smokers quit with E-Cigarettes for this time, preventing over 400,000 cigarettes from being smoked daily, collectively saving our customers over £500 million! According to recent estimates that a single cigarette costs on average 20 minutes of life (7), we have potentially saved SMOKO customers over 32,000 years of life! Now that isn't too shabby!
Summary
