Vaporising is becoming ever more popular in the UK. You cannot walk through a city centre in the land without being engulfed in a cloud of thick, sickly sweet smelling vapour. This method was historically used to utilise the medicinal properties of various plants without physically burning them. The modern technology it has evolved into, has primarily been produced as a way to lessen the harms caused by the consumption of Tobacco.
There are now several shops popping up on every high street in Britain selling a myriad of various vaporisers and liquid “E-juices” containing Nicotine, one of the most addictive substances known to man.
As CBD is legal in the UK it means that many companies are now producing 100% legal, Non-addictive, Non-carcinogenic, and non-toxic alternatives to consuming Tobacco or maintenance dosing on Nicotine “E-liquids”.
Vaporising CBD has been shown in clinical studies to help reduce Tobacco consumption by up to 40%whilst still providing the calming, anxiolytic effects that Tobacco consumers say is why they started, and continue to consume the deadly drug in light of just how dangerous it is.
These legal CBD vape liquids contain less than 0.2% THC, the currently illegal Cannabinoid, varying percentages of CBD, other trace Cannabinoids, and Terpenes.
In this article, we’ll be looking at how vaporising CBD differs from other consumption methods. We’ll be breaking this piece into several sections.

What is a Vaporiser?
A vaporiser is a device that is used to vaporise key chemical components of plant material, mainly Cannabis and Tobacco. However, there are other herbs and herbal combinations that are produced specifically for inhalation via vaporisation.
Vaporising works by heating the plant material to an optimal temperature turning them into vapour which is then inhaled, getting the effect without combustion. This allows for the Cannabinoids, Terpenes, and Flavonoids to be extracted without burning the physical plant material which greatly reduces any potential harmful effects from the inhalation of combusted carbon-based plant matter.
What is CBD Vape oil?
CBD vape oil is a Cannabidiol preparation that is specifically manufactured to be vaporised.
Cannabis is gradually being re-legalised and tentatively welcomed back into the global fold in more and more countries around the world each week. Consequently this speeds up the evolutionary process producing ever-increasingly more sophisticated and precise methods for extracting, isolating and distilling individual Cannabinoids and Terpenes.
CBD vape oil is often available as an “E-Tincture” which is an oral tincture that can also be used with handheld vaporisers, vape pens, and e-cigarettes. These mixes typically consist of CBD Isolate VG and/or PG and artificial flavours.
There are many different carrier oils for CBD and other Cannabinoids when producing vape juices. The traditional ones using VG or PG as thinning agents and for generating vapour clouds are slowly being replaced with different oils and more refined methods of extraction.
One such method is supercritical C02 extraction which is a safe, environmentally friendly and highly effective method of producing quality Cannabinoid vaporiser cartridges.
Carbon Dioxide (C02) is a supercritical fluid, this means that it converts into a liquid form when pressurised. It is a pure chemical substance that occurs naturally and when used correctly leaves behind no residue. This method also maximises the number of Terpenes that are extracted, which could potentially provide further health benefits from these compact chemical compounds.
Another new innovation is the combination of Cannabis derived Terpenes and butane extracted shatter diluted with MCT oil producing a semi-viscous amber coloured vape liquid. This is another method that is quickly growing in popularity in the UK.
Using CBD extracts such as Shatter, Wax and Crumble in a vaporiser that has a special coil to “dab” extracts is also a great subtle way of getting the CBD you want.
We’ll explore “dabbing” further in the section below titled “Maximising the efficacy of CBD”
Understanding the bioavailability of CBD
What does bioavailability mean?
Bioavailability is the degree to which a drug or other substance is absorbed when introduced into the human body. There are various methods of consumption for different drugs which will yield differing results. Intravenous administration, for example, has 100% bioavailability as it is administered directly to the bloodstream negating the first-pass effect, whereas oral ingestion and topical applications typically have a far lower rate of absorption.
The Bioavailability of CBD when ingested is around 10%, it is low because CBD is hydrophobic, this means that it’s not very water-soluble so when ingested will quickly diffuse out of the blood and into surrounding fatty tissue leaving only a small percentage to be metabolised by the liver. The low binding affinity of CBD with Cannabinoid (CB) receptors in the gastrointestinal tract, which means that the potency diminishes en route to being metabolised and passes into the bloodstream.
Vaporising CBD greatly increases the bioavailability up to around 50/60% when vaporised.
This is a result of negating the “First-pass effect”, which is the phenomenon in which the bioavailability of a substance is reduced by it having to pass through the gastrointestinal tract and be metabolised by the liver before entering the bloodstream.
This decreases the potency of CBD meaning that you’d have to ingest much more orally to equal the same amount consumed by vaporisation.
This is antithetical to THC who’s bioavailability is greatly increased when orally ingested.
This may be because when THC is orally ingested it breaks down via the liver. The body converts it to 11-hydroxy-THC (11-OH-Δ9-Tetrahydrocannabinol), this process increases the number of THC metabolites and increases metabolism.
The high binding affinity of THC with CB receptors in the gut is thought to be the reasons behind the increase in potency.
Vaporising is also the quickest Cannabinoid delivery method. Typically passing the blood-brain barrier with in 90 seconds of inhalation. Along with the increase in absorption rates, this makes vaporising one of the most effective ways to consume CBD.
Maximising the efficiency of Cannabidiol (CBD)
As mentioned above in the previous section Vaporising is already regarded as the most effective means of consumption, however, there are different levels of vaporising.
“Dabbing” is the flash vaporisation of Cannabinoid extracts. By using a special attachment made from either glass or metal attached to a bong. It is then heated to several hundred degrees with a blow torch or an electronic heating device known as an e-nail. This is how the high potency extracts are consumed.
The concentrates wax, Shatter, crumble etc are then dropped onto the heated surface and inhaled through the water in the base to help cool the vapour.
These various extractions are gradually becoming more ubiquitously available in the UK as dabbing continues to grow in awareness and popularity.
Dabbing is a much more intense sensation and consumption experience than traditional vaporising and can often be overwhelming to novices, however, a tolerance is quickly acquired and lost when ceasing and starting dabbing again, making it a great way to titrate high doses.
Dabbing is arguably the quickest and best way to consume CBD as you get all of the benefits of vaporising but with a much higher concentration and with a near enough instant effect.
How much oil should I Vape?
Given what we’ve learned above about the bioavailability of CBD when vaporising, less than you might think!
Although CBD doesn’t get you high like THC does, it still nevertheless effects you. Small doses have been found to have a “wake-inducing effect” whereas paradoxically in larger does it can have a sedative effect.
Vaporising CBD has very few side-effects, its non-addictive, non-toxic, not carcinogenic, and it supplements your Endocannabinoid system too!
It is advisable to start low and build up to a dose that works for you. On average a dose is typically 10mg- 20mg when consumed orally in a tincture. That can be reduced to less than 10mg and still have the desired effect given the greatly improved bioavailability when it’s consumed with a vaporiser.
Ultimately, Vaporising CBD greatly increases its bioavailability making it the most cost-effective way of consuming CBD. It’s discreet, it allows you to take precise doses and is the fasted way to consume CBD.
The Vaporisation market may still be in its infancy in the UK but you can rest assured that CBD will be a primary driver and key influence in the markets evolution and development moving forward.
