CBD Vape Oil UK: Is it Legal?

Yes. CBD vape oil in the UK is legal if derived from hemp plants with less than 0.2% THC by volume. Yet, CBD brands are not allowed to advertise it as having medicinal benefits.

In 2016 the Medicines and Healthcare Products Regulatory Agency (MHRA) decided to recognize the medicinal benefits of cannabidiol (CBD). However, according to its “legal outlook,” any medicine sold in the country must be properly licensed and approved before being marketed and sold to the general public.

In the case of cannabidiol, there is currently no authoritative program available that licenses CBD products as medicines. Therefore, you’ll find that no reputable CBD vape oil sellers in the UK make any medical claims whatsoever.

Also, UK law dictates that CBD vape juice must not contain nicotine. Please note that vaping is banned in most public places in Britain, including public transport, hospital grounds, and even certain music venues.

All UK CBD companies had to apply for novel food authorization by March 31, 2021. It is now illegal to sell any CBD products lacking this qualification.

CBD Vape Oil UK: What Is It?

There are two types of e-liquids:

  • Marijuana-derived: Containing high amounts of THC
  • Hemp-derived: Containing high levels of CBD but a maximum of 0.2% THC

Manufacturers use CO2 extraction to take cannabinoids, terpenes, and other useful compounds from hemp. CO2 (carbon dioxide) can adopt a unique state between liquid and gas phases known as a ‘supercritical’ state. Therefore, it can become pressurized without being heated to extreme temperatures.

For this reason, it is the perfect compound for extracting CBD from hemp. It pulls virtually 100% of the active cannabidiol from the plant material without denaturing the CBD or leaving the extract laden with toxic solvent residue.

Once the CBD is extracted from the plant, it must go through multi-stage purification processes before being put into a vaporizer and inhaled. Unfortunately, some manufacturers still use butane (lighter fluid) to extract the compound from the plant material. Butane is dangerous because, in addition to being explosive and flammable, it can also leave behind solvent residue in the end product.

Therefore, you must look at the ingredients used and the extraction process when browsing CBD vape oil for sale in the UK.

Should I Focus on the Strongest CBD Vape Oil in the UK?

No. When looking for CBD vape oil in the UK, the cannabidiol concentration isn’t necessarily the most important thing. We know of products containing an impressive 2000mg of CBD and e-liquids with 30mg+ of the compound per ml. This is certainly a useful concentration if using CBD to help with anxiety or pain. After all, vaping provides a high level of bioavailability and fast-acting effects.

Nonetheless, it is crucial to focus on CBD oil vape products in the UK with third-party lab reports. Also called certificates of analysis (COA), lab reports outline the cannabinoid content of the product. COAs also let you know if a product is tested for heavy metals, pesticides, and other harmful chemicals.

You must also look into the thinning agents included in the list of ingredients. As we’re about to show you, certain ingredients could have a devastating effect on your health.

What Are the Dangers of CBD E-Liquid in the UK?

CBD oil vape UK products have an element of regulation to protect consumers, although it is far from guaranteeing quality. However, there are potential issues even with the best CBD vape juice.

Medical experts are concerned about the general effect of vaping on the lungs, in particular, as well as the ingredients included in many e-liquids.

In the United States, a vaping illness epidemic was linked with 61 deaths from over 2,700 confirmed cases. Most people hospitalized consumed illegal THC oil, while vitamin E acetate is the ingredient most associated with the outbreak. However, the American CDC did not rule out other chemicals as the cause.

The Trouble with Thinning Agents

Research is still ongoing concerning the long-term effects of vaping. The suspicion is that the habit could damage the lungs. A CDC report outlined that using a vape pen 5+ times a day gave someone the greatest chances of developing a lung injury.

Even if casual vapers are less at risk, there are unquestionably problems with certain thinning agents used in vape juice. These chemicals are designed to make it easy to vaporize the oil. If you try to vape regular CBD oil, you’ll find it too thick and will likely clog your vape pen.

Vegetable glycerine (VG), propylene glycol (PG), medium-chain triglycerides (MCT) oil, and polyethylene glycol 400 (PEG 400) are all used as thinning agents. However, few brands use the latter due to health concerns.

Thinning agents are required to make vapor out of CBD oil. However, some thinning agents are safer than others.

Unfortunately, it seems as if the other three ingredients aren’t as safe as originally thought. A study published in the Journal of Alternative and Complementary Medicine in 2017 looked at the four aforementioned thinning agents.

Researchers heated them to 446 degrees Fahrenheit (230 degrees Celsius) and tested the vapors for three carcinogenic substances: formaldehyde, acrolein, and acetaldehyde. They found that PEG 400 produced the highest levels of formaldehyde and acetaldehyde. PG also produced a significant degree of formaldehyde.

Meanwhile, a study published in PLoS Biology in 2018 found that VG and PG, when used alone or with flavors, were toxic to cells.

What About MCT Oil & Terpenes?

MCT oil and terpenes are often hailed as safe alternatives. However, the jury is out on both. A study published in Frontiers in Pharmacology in 2019 found MCT oil in samples of vape liquid in some people diagnosed with a vaping-related lung injury during the epidemic. MCT oil also produces reactive aldehydes and several hydrocarbons when heated. However, overall, there isn’t enough evidence to say whether MCT oil is safe or harmful to vape.

Regarding terpenes, a 2019 study by Portland State University published in ACS Omega found that more toxins come from terpenes when heated than THC. The chemicals produced included xylene and benzene.

Therefore, it seems as if there isn’t any specific vape liquid thinning agent that is classified as ‘safe.’ Please bear this in mind before looking into the best CBD vape products in the UK.

How to Determine the Best CBD Vape Oil UK Brands

There is a huge assortment of products available with radical disparities between price and quality. So, how can you pick the best CBD vape oils in the UK without getting ripped off?

As it happens, there are only a handful of things you need to ask yourself when shopping for CBD e-liquid for sale in the UK. Check out our handy table below to learn more.


Question to ask yourself before buying

The answer to look for

Where was the CBD sourced from?

When buying UK CBD vape oil, you’ll want to make sure that the oil has been sourced from industrial hemp, as this is the only kind of cannabis plant material that is legal in the United Kingdom.

Does it contain THC?

While you likely won’t be coming across any CBD vape oils in the UK that contain THC, it is still important to double-check as you could get in serious trouble if found in possession of high-THC marijuana.

Is it advertised to treat medical conditions?

As we said before, CBD vape e-liquids in the UK are legal as long as they are extracted from industrial hemp and used as “nutrition supplements.” In other words, they can NOT be advertised as medicine.

Was there a thinning agent used?

Often, UK CBD vape oil is unnaturally “thinned” with a thinning agent to make the thick mixture more compatible with a modern vape pen. Be sure to look out for products that contain PG or PEG, as these have been known to break down into formaldehyde when heated.

Is the CBD content lab-verified?

One thing that you’ll ABSOLUTELY want to look out for when considering UK CBD vape liquid is whether or not the product’s CBD content has been verified by an independent third-party laboratory. If it hasn’t then stay away.

Its CBD Calm products contain CBD isolate and a 70:30 mixture of PG and VG. All Vapoholic products are certified THC-free, and the prices are incredible. You can buy 3000mg of CBD e-liquid for £30 at present on sale. However, even the usual price of £60 offers remarkable value for money.

Vapoholic has many positive customer reviews and is well worth considering if you want low-cost, high-quality CBD vape juice.
