What Is a CBD E-liquid?
E-liquid – also named as e-juice is the liquid that fuels an e-cigarette. It is vaporised by the battery powered atomiser (e-cigarette) to imitate the sensation of smoking. It’s normally composed of 2 primary ingredients –an atomising base (PG-VG) and the flavouring.
With e-cigarettes becoming very popular lately amongst cigarette smokers, the use of vaporizers & E Liquid has also branched out into our world of health and is considered the most convenient ways for taking CBD.
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.
CBD E-liquids Bases
When it comes to e-liquid, two concepts constantly crop up: PG and VG.
This can seem confusing to beginners, but knowledge of these two ingredients can greatly enhance your vaping experience. Both e-liquid bases, outlined below, are equally safe and approved by the FDA.
• PG (Propylene glycol) – A clear, colourless liquid which is usually used as a flavouring carrier in food products. It has been utilised in asthma inhalers and nebulisers since the 1950s. Propylene glycol delivers the flavour very well and provides strong throat hit.
• VG (Vegetable Glycerin) – A colourless, odourless, and tasteless viscous liquid. VG is exclusively derived from plants (soybeans or palm). E-liquids can be made from up of 100 % VG or PG, however, nowadays e-liquids are usually mixed to take advantage of both. Vegetable glycerine is thicker than Propylene glycol and it doesn’t dissolve the CBD as good as the PG. It produces better vapour than PG and is a great sweetener as well.
Nowadays you can pick from so many flavours from Creme Brulee to a breakfast cereal, choosing is like standing in the middle of a candy store.
E-juice usually contains 5 – 20 % flavour. E-liquid manufacturers will use either natural or artificial flavouring, some vendors go as far as making their own extracts.
Some flavour enhancers, acidifiers, and preservatives are still unknown to us and not all of the flavourings are completely safe as well. For example, a very commonly used molecule pulegone (mint flavour) produces hepatotoxin, which can damage the liver.
When choosing e-liquids, you should pay attention to its composition. You don’t want your e-liquid to contain diacetyl because accumulated exposure to this volatile compound can cause severe bronchiolitis.
