Contrary to the belief that vaporisation is “new-in-town”, vaporiser technology has been explored since the 1960’s. Herbert A. Gilbert was the first to file a patent in 1963 after losing his dad to lung cancer. He created prototypes but failed to commercialise the product. It wasn’t until Hon Lik introduced his “cig-a-like” e-cigarette in 2003, that the vaporisation industry really took off!
What is Vaporisation?
Vaporisation can be defined as the act of inhaling vapour through a personal vaporiser. A heating mechanism extracts the active ingredients of a compound converting them to vapour which is then inhaled. The heat applied has to be high enough to extract the compounds, but low enough to avoid combustion.
This is an extremely effective way of ingesting the essential compounds, such as the cannabinoids and terpenes of a plant like hemp. For plants and extracts vaporisation, you want to use a dry herb vaporiser, or alternatively, there are CBD e-liquids for e-cigarettes.
Why vape CBD?
CBD can be taken orally as a cannabis-based concentrate or extract. When compared to vaporisation, ingesting CBD orally poses a number of drawbacks including a delayed effect and inconsistent absorption.
To be sold legally in Europe, CBD is normally extracted from certified industrial hemp which is a variety of cannabis grown in a controlled environment, specifically for use in industry. It has to have less than 0.3% THC (the psychoactive compound in cannabis) to be certified.
Not all of the CBD you consume will directly affect your body; only a certain percentage will be able to enter your circulation to produce its active effects. This is called the “bioavailability” and is based on the way you introduce CBD into your system.
There are two main points here to understand. First, CBD is not very water soluble. Instead of staying in your bloodstream, it rapidly diffuses out of your blood and reduces the amount of bio-active CBD that can enter your circulation. Before entering the blood stream, CBD has to enter your gut. During this transition, the liver will actively break down bio-active compounds, which is referred to as the “first-pass effect”.
During vaporisation, CBD enters your lungs and diffuses directly into your bloodstream rather than passing through your gut and liver. This avoids “the first-pass effect” altogether, allowing nearly four times as much CBD to enter your circulation for a maximum bioavailability of roughly 50 to 60 percent. That means for every 100 milligrammes of CBD that you vape, 50 to 60 milligrammes will actually reach your bloodstream.(the oral bioavailability of CBD is roughly 15 percent). Basically, you can achieve the same beneficial effects with a much smaller amount of CBD.
What is CBD e-liquid?
CBD e-liquids are normally made up of four basic parts: VG, PG, CBD and flavouring. Unlike nicotine-based e-liquid, CBD concentration can vary massively in strength going from 25mg to 1000mg per bottle.
VG is short for Vegetable Glycerine and is also commonly used in foods and is responsible for producing the vapour. The higher the VG content the thicker the clouds! PG stands for Propylene Glycol and is commonly used as a food preservative or sweetener. It provides the “throat it” and flavour.
Your final choice will depend on your personal requirements, smoking habit and flavour preferences.
How Does Vaporisation work?
When it comes to choosing a dry herb vaporiser, there are only two types of heating mechanisms to consider; conduction and convection. These mechanisms will
These mechanisms will affect the quality of vapour and it’s good to know the differences before buying your own device.
Conductive Heating vs Convective Heating
This is the most direct way to heat the plant material. Vaporisers using conductive heating contain an electronically heated surface filled with the dried flowers or extract. The “hot plate” is then heated to an ideal vaporisation temperature, directing heat throughout the chamber and converting the cannabinoids and terpenes into vapour.
Conductive heating mechanisms tend to be found in the more basic devices. You can achieve very fast warm up times but there is also a higher risk of combustion.
With convection heating, the air in the chamber is heated first. Once the air has reached the optimum temperature, it is moved either by a fan or through inhalation. This heats the flower or concentrate, converting the cannabinoids and terpenes into vapour without burning the substance. To avoid combustion, the herb should not come in contact with the heating element.
Convection allows for accurate temperature control, whilst heating more herb with a lower risk of combustion. Due to these advantages, the cost for convection vaporisers is usually more expensive.
Despite these differences, most vaporisers use both convection and conduction to some degree. Convection is better at achieving superior taste thanks to the precise temperature control. However, there are still some great conduction vaporisers on the market with reduced sizes, faster warm up and lower prices.
Remember vaporisation isn’t the only way of getting CBD into your body. There is a range of CBD products available to you, in different forms, via our online store, making CBD easy to take wherever and however you like.
Everyone will have different needs, wants, and expectations when looking for the best way to ingest CBD. So it’s important to figure out where you will be using it, how you will be using it, and what features matter most to you.
