The Best Dry Herb Vaporisers for Medical Cannabis in the UK (2025 Updated Guide)

The landscape of medical cannabis vaporisers has evolved significantly in 2025, with new technology making devices more efficient, user-friendly, and affordable than ever before. As UK medical cannabis prescriptions continue to rise, finding the right vaporiser has become essential for patients seeking effective medication delivery without the harmful effects of combustion.

This comprehensive guide—updated for June 2025—examines the latest dry herb vaporisers available to UK medical cannabis patients, comparing performance, value, and medical suitability. Whether you're new to medical cannabis or looking to upgrade your current device, our evidence-based recommendations will help you make an informed decision.

From this article, we hope that you can come away with a better understanding of dry herb vaporisers, how to use them with your UK medical cannabis prescription, and know more about what to look for/ how to cut through the BS in marketing.

Just a heads up though, when it comes to health, in our opinion there should be no compromise, and as such, with limited devices that have been cleared for medical use, the top end of our picks are expensive.

However, that isn’t to say there aren’t safe to use devices that are much cheaper. So fear not, we’ll help you know what to look for, and how to use them whilst being conscious of certain safety factors.

When it comes down to it, a dry herb vaporiser is essentially a small device that uses precisely controlled heat to extract the active ingredients in your herbs and turn them into vapours. Unlike smoking/ combustion, dry herb vaporizers don’t produce dangerous chemical by products/ carcinogens and other combustion byproducts when they’re used. There are several types of dry herb vaporizers on the market, but most fall under the category of handheld vaporizers for use on the go, although some desktop devices are well worth considering for medicating at home.

They all function generally in the same way, but there are some key things to look out for to find what will suit you. Such as, the size of the bowl. How much dose it fit in, with most prescribed dosages being around 0.2G, a dry herb vape that naturally fits this amount would be very convenient. Where as a device that holds 1G in the bowl may be a bit overkill! 

In my opinion, the Mighty dry herb vaporizer is the best device on the market currently, and I have been using one for two years now alongside other devices. It’s created by a company known for producing quality, well engineered and long lasting vaping products, and it’s been praised by experts in the industry. 

The Mighty is a top-notch device that’s capable of producing extremely pure and flavourful vapour and has a medical device option (Can be prescribed to save VAT for medical patients!). It also comes with a few other great customisations due to its popularity, like glass mouthpieces, or whips to pass the vapour through a bubbler, mesh pads to use with concentrates and dosing capsules for ease of use when out and about.

The only real downside to the Mighty is the price, but it’s still an excellent choice for anyone looking for the best dry herb vaporizer on the market as you have the peace of mind of owning a rock solid piece of kit. Other constructive criticism of the unit is that by design it has plenty of places for small bits of flower to get trapped when filling. This means that it can be a smelly boy when stored, which isn’t always ideal when you’re carrying it in a bag with other items!

Thankfully there are plenty of carry cases that can resolve this issue, including a waterproof pelican case that I recently grabbed that fits snuggly! Lastly, it’s quite a big device, it’s not like these tiny disposable vapes you can get these days. It takes a lot of power to consistently heat something at 210C for a few minutes at a time, and as such it takes big batteries! So the Mighty is a chunky boy, but that added battery life compared to it’s smaller counter part the Crafty, is a worthwhile compromise in my eyes, with roughly 5-6 doses between charges after a year of use. 

The Arizer Air II is our best budget buy. Though it’s not quite as popular as the Mighty, it is significantly cheaper and easier to use. The Air II is a durable vaporizer that’s been praised by experts in the industry and users alike. 

It’s been said to produce excellent vapor at a great value, and it’s definitely a solid pick for anyone on a budget. The Arizer Air II comes with a durable, easy-to-use design that makes it ideal for beginners or anyone who wants an affordable and effective dry herb vaporizer. From my personal experience it certainly stacks up to the Mighty in terms of vapour production and flavour, and is a great pick for someone stepping into using a Dry Herb with this budget range. 

I can't vouch personally for longevity of durability, but haven't heard any notable complaints. So would give that a confident thumbs up, as usually when a device is known for issues we'll hear about it!

*Continued below!* 

Another great piece of kit from Arizer with their SOLO3. A step up from the Air, this device delivers incredible vapour for it's price tag and a huge leap in battery capacity compared to it's smaller cousin.

At this price range, the SOLO 3 is competing directly with the Mighty by S&B which is no small task. The thing is, in many ways it delivers. The glass stem setup makes a world of difference for flavour and how smooth the vapour is. It also has a fantastic heat up time meaning it minimises time out and about when dosing. 

From there on it boils down to personal preferences, and where you are setup. The size of this is getting to the bulkier side of things whilst still being easier to handle than the Mighty size wise. 

If you are stuck around this budget range, it's hard not to take the step up in quality for another £50 or so with the Venty. However if this is the top of your budget, rest assured that you're still investing in a great piece of kit. 

Yet another great device from Arizer!

The PAX 3 is a small, unique device which can easily fit in a small case or even your pocket. Although do remember that Dry Herb Vaporizers require alot of power. So you will be compromising on battery life slightly with smaller devices.

With it's unique form function, it doesn't draw attention to itself as a vaporizer at all. It looks almost likea small power bank for your phone. 

With an easy to load chamber and a magnetic clip on mouth piece, there is no fiddly unscrewing to deal with. 

Although it doesn't produce the most vapour compared to larger devices, this is a happy compromise for the size and convenience of using your medication on the go. 

Personally I don't think you can go too far wrong with a PAX, and although there are better products on the market, for this price it's a great piece of kit from a reputable brand. 

Ok so by now you've come across a few great devices, but there are 3 devices in particular that regularly come up when talking about premium portable dry herb vapes. 

One thing I have found true with these devices is that you get what you pay for. These next three devices not only deliver industry leading extraction but warranties that give you peace of mind to back up your investment. 

Having said that, these three devices have their own unique pros and cons, so it's worth weighing up what would suit your needs best! Let's jump into it. 

So what can you expect from these top performers? 

Each of these devices are renowned for having the best tasting vapour, processing material efficiently, and having the power to take you through the day with multiple doses. 

So the only question is, which is best suited for you out of these three options? 

The Venty by S&B

Introducing the Venty by Storz and Bickel. 

This device comes up time and time again and for a good reason. It will churn through material no matter what temp or how coarse your grind is. No stirring half way through a dose or fiddling. Simple fill it, turn it on, and off you go. 

With adaptable airflow, the Venty really allows you to dial things in for your own needs. Open airflow makes for volumous smooth clouds, or tighten things up for a deep hot extraction getting every last bit out of your material. 

Now i'm going to make a bold statement here, but the Venty is my personal favourite vape and I have tried them all. My Venty has over 1,200 hours of use and still churns through material like day one. It stood by me during two major brain operations as the main piece of kit I used for my meeication so it's really been pushed through it's paces. 

How does the Venty compare to the Mighty? 

Prior to the Venty I was a Mighty user for a couple of years. Even after all of these years the Mighty still stands the test of time as one of the best options on the market. Testiment to the quality that Storz and Bickel deliver with their products. But the Venty is a worthy upgrade if you can afford it over the Mighty. 

Not only does it heat up faster, but it works through materials faster which matters if you're having to vape outside at times. 

The variable airflow and form of the Venty are also big upgrades. Though technically they're similarly sized, the thinner profile fits in the hand much better. Going for either option is going to land you with a great piece of kit, but if you have the budget, the Venty does have the edge! 

The Tinymight 2 has been at the forefront of premium dry herb vapes for a few years now and it still stands proud and undefeated in many ways. 

Known for it's excellent extraction rate, bold flavour and throat hit similar to smoking, and the interchangeable battery keeping it going all day long, the Tinymight 2 has certainly earned it's place on this list. 

But is it for everyone?  The answer is, no. But don't let that put you off as I explain why this is such a great piece of kit, but not ideal for every medical patient. 

So what can you expect from the Tinymight 2? 

The glass steam makes a great improvement over plastic options from other devices and even comes with a spare! Furthermore this heats up in record time compared to the Mighty or Venty. 

The hit this device provides are solid, and will favour those who have come across from smoking emulating the throat hit as closely as you can get without combustion. 

One down side however is that to process the whole chamber of flower, you need to mix it half way through use. Otherwise you tend to have brown material in the middle and light green on the outside. A quick stir and you're good to go to finish this off promperly. 

For many this is a non issue as the other features are well worth it and you will still process a dose much faster than other similar dry herb vapes. I bring this point up mainly as for some patients, having to fiddle half way through may not always be practical, particularly when out and about so it's worth considering. 

Over all, the Tinymight 2 is an absolute beast, and the build quality in the hand is second to none. 

The New Kid On The Block - The Frolic

There has been a lot of excitement in the past 6 months about the Frolic, one of the newer medical cannabis dry herb vapes to be released. 

Why the hype? It promises to deliver the same quality vapour and performance as the Venty, but with some key differences. Faster heat up time, and being able to swap out the battery. 

The thing is reports have been coming in from patients with so many different opinions, so I finally managed to get my hands on one to see if it actually lived up to the hype. 

In short, it does! Let's find out why

Is the frolic needed in a world of Ventys and Tinymights? 

Yes, as with anything there are always pros and cons to different setups. Those who love the Venty will happily admit that the fact you can't change the battery is a big drawback. Those who love the Tinymight will admit that it would be better if you didn't have to stir your chamber half way through. 

These two drawbacks on the other devices are what give the Frolic the edge when it comes to day to day medication. 

Back in 2007 I was sat in a bar in Amsterdam wondering what on earth was going on across the road. Through the window of a coffeeshop I could see this space craft looking thing filling up a balloon. I had to go investigate, and low and behold I was met with the Volcano, and I knew I must have it! Although it would take me another 15 years before I owned one myself, it's now by far one of the most effective and solid devices I own, and with good care will likelyout last me as it's built like a tank! 

So what is it, what's the bag about and what makes it so good? 

Flavour and ease of use: As discussed previously, the terpene profile is the first part of the vapour to be released. So with a typical handheld device where you are directly inhaling the vapour, the terpy flavour is lost after the first 5-10 pulls. However, with the volcano you have the option to fill a reusable bag with your vapour which mixes those tasty terps in with the rest of the bag balancing the flavour. 

The bags have an easy to use mouth piece that enables you to inhale at your pace when youre ready. The ability to wait also means that the vapour is cooled down, which can help those who struggle with a scratchy through when vaping! 

Table top dry herb vaporizers have the advantage of faster heat up, no waiting for charging, and generally better vapour production. However, not all vapes are made the same. 

When it comes to reputable build quality matched by a focus on safety with medical options available, the Volcano by Storz and Bickel is hard to beat. 

With various models available, a new Volcano can be picked up between £300 - £500 depending on model, location and whether you manage to grab a 420/ black friday sale. 

So what makes this the top recommendation for desktop? Let's jump in! 

Beyond the bag, there is more to it. Those with higher tolerances may find a bag not enough for their needs, but with hybrid you also have the option to add a 'Whip', which is a long tube with a mouth piece. You can then use the volcano as you would a normal vape, the difference being with further to travel the vapour is cooler, and I personally found as a reslt of this youre able to extract more from your plant material without drying out your throat. So with its conveniece to be setup on your desk/ next to your chair, it's a great way to work efficiently with no worry about battery life. 

The convenience of a desktop vape when at home is that it's reliable, fast to use, and offers options such as the easy to use balloon systems that allow vapour to cool of for longer. 

One area where the Arizer Extreme Q wins over the volcano is the remote control. Although there are apps for the volcano it isn't universal, and ultimately some times and old school simple to use remote is much easier let's be honst. 

I just had brain surgery, and it meant that everytime I got up it was followed with pain. So I plan my movements to minimise this. So by being able to turn it off remotely, pre heat it, or fill a balloon and sit down again whilst it works it's magic is a real help. 

The little accessibility details in devices like this can make a world of difference. So as a massive fan of the volcano for almost two decades, you can take my praise seriously when i'm talking about Arizers solution here. Well done to the team for thinking about these details.

Beyond the remote there are a tonne of reasons to take this setup seriously. Sure you have to accept a little more plastic than the Volcano, and ultimately it isn't as iconic, but when it comes to effective use of your medication, looks don't really come into it right? 

This desktop setup is small considering what it can do, and is easy to maintain. Using the whip allows you to take things at your own pace and dial in the temp as you go, or you can use the bag system for an even more portable experience. 

Beyond this the possibilities are endless as you can customise it with bubblers, prep it for concentrate use and more. One thing is for sure, you get a hell of a lot for your money with this setup and this is a major reason why it's become so popular. 

Quitting smoking isn’t easy, and I’m not just talking about those of you who use tobacco in your joints, but even those who roll pure, or have been using a bong/ pipe. Vaping cannabis is not easy to step over to from smoking, and time and time again we hear customers and patients who complain about how it doesn’t get them as high, it doesn’t give them the same throat hit, it tastes horrible and that they can’t quit as a result.

If you experience this difficulty when swapping over, don’t worry, you’re not alone!

Combustion comes with a few other things in the mix than vaporizing, and as such, you are actually absorbing a much richer profile from the plant, but also a few other nasty things too. The last thing you want to hear when feeling hopeless trying to swap over is to just keep at it, it will get easier, but it’s true. Stay the course.

 Aside from the fact that it is undeniable that smoking is more harmful with more associated risks than vaping alone, vaping can give stronger effects and more control than combustion with time, furthermore it will get you more from your flower as you dial in your tolerance. So stick with it, it is worth it, and there are no silly questions, so if you are still struggling, don’t be afraid to ask on forums, or heck drop me an email on here and I’ll be happy to help!
