CBD Unboxed - Strongest CBD Vape Oils

What is CBD Vape Oil?

As the name indicate, CBD vape oil is a CBD-containing liquid that can be vaporised and therefore used for vaping or smoking. Also known as CBD juice, vape oil and e-liquid, this liquid produces a vapor that can be inhaled when heated with a vaping device.

This is not to be confused with traditional CBD oil – also known as CBD tincture – which is taken sublingually and not suitable for smoking.

CBD vape oils tend to contain three main ingredients, although the final composition will depend on each individual brand and product:

  • CBD: This could be pure cannabidiol (known as CBD isolate) or whole hemp extract
  • Carrier: A liquid in which the CBD extract and flavouring agents are dissolved, making it possible for the CBD to be inhaled. the two main carriers are Vegetable Glycerin (VG) and Propylene Glycol (PG). However, some products use alternatives, such as MCT oil.
  • Flavouring: Most CBD vape oils will have a sweet, minty, fruity or herby flavour to appeal to different people and tastes.

Advantages of CBD Vape Oils & E-Liquids

CBD vape oils have many advantages over other CBD products such as CBD oil, CBD gummies or CBD capsules.

  • Easy to use and discreet – Whether you are vaping using traditional vaping juices or CBD infused e-liquids, most people will not be able to tell the difference especially since many e-liquids come in various flavours.
  • Increased bioavailability – Inhalation is an efficient way to consume CBD because it bypasses the digestive tract and liver allowing CBD to be readily absorbed through the thin membranes that line the air sacs of the lungs (alveoli) where it enters directly into the bloodstream.
  • Fast acting – Due to its increased bioavailability, CBD vaping will usually act much faster than other products that needs to go through the digestive tract.
  • Great tasting – Whilst traditional CBD oil will usually have an earthy or grassy taste, CBD vaping juices will usually be flavoured with agents such as raspberry, lemon, strawberry, peach or blackcurrant making it a great tasting alternative to oils which tend to leave an unpleasant aftertaste in your mouth.
  • No addictive or withdrawal issues – Finally, CBD drinks are a natural remedy that can be taken by almost anyone and possesses none of the addictive or withdrawal issues that other pain management or anxiety medications may present.

Are CBD E-Liquids Legal?

CBD is legal in the UK as long as the plant which have been grown contain less than 0.2% of THC, the legal limit in the UK. The reason for this is that THC is known to be a psychotropic substance and limiting the amount of THC ensures that CBD is safe to consume and will not have any psychoactive effects. In other words, CBD won’t get you “high”.

Personal Use

You will not be arrested or fined for buying, consuming or carrying CBD products, anywhere in the UK, as long as it has less than 0.2% THC in it.

What is illegal is to grow the hemp plant(s) yourself, at home. Growth for personal use is strictly prohibited by the Misuse of Drugs Act of 1971. To do so, could result in up to 5 years in prison and/or an unlimited fine.

New Regulations & Guidelines

As CBD is eaten or drunk it falls under “novel foods”, which means that the Food Standards Agency (FSA) oversees CBD products and they can therefore enforce new laws and regulations and they have recently done so.

Since the 31st of March 2021, all CBD products must be approved by the FSA in order to be sold in the UK. Failure to do so will result in the products being removed from the shelf. This request for approval means that the exact ingredients within a CBD will be known, making it safer for the general public.

Health Benefits of CBD Vape Oils

The human body contains a specialized system called the ECS (the endocannabinoid system), which aim is to regulate a variety of functions such as sleep, appetite, pain and immune system response. The body also produces endocannabinoids, which are simply neurotransmitters that bind to cannabinoid receptors in your nervous system.

CBD is believed to interact with specific receptors, specifically the CB1R and CB2R.

  • CB1 receptors, which are located in various regions of the body, with a large concentration in the central nervous system and brain, co-ordinate mood, emotion, appetite, and other functions.
  • CB2 receptors are more commonly found in the immune system and are responsible for controlling inflammation and pain. CBD stimulates these receptors and induces the body to release serotonin.

Serotonin, or 5-HT, is a neurotransmitter that carries signals from one neuron to the other. CBD increases the level of serotonin, which, in return, helps reduce pain, reduce inflammation as well as provide a range of other health benefits, which include:

  • CBD for Pain Relief: CBD has analgesic (pain relief) properties and can help with many painful conditions such as arthritis, headache disorders, migraines, back pain or period pain.
  • CBD for Sleep: CBD has a calming effect on both the mind and the body, allowing people to fall asleep more easily and stay asleep throughout the night.
  • CBD for Stress: CBD helps reduce stress and calm both the body and mind, through its interaction with both the Hippocampus and the Amygdala.
  • CBD for Anxiety: CBD has both anti-anxiety and antidepressant properties, and can be a great alternative to anxiety medications which have known side-effects.
  • CBD for Headaches: CBD reduces the frequency of headaches as well as reduce stress and improve sleep, two major triggers of headaches. But CBD also has strong analgesic (pain relief) and antiemetic (prevent vomiting) properties which can help people with headache disorders during an attack.
  • CBD for Arthritis: CBD has antiarthritic, analgesic (pain relief) as well as anti-inflammatory properties and as such is a great option for people suffering from arthritis.
  • CBD for Cancer: CBD helps relieve some of the symptoms of cancer as well as reducing the side of effects of cancer medication such as nausea, vomiting and pain.
  • CBD for Epilepsy: CBD helps reduce the frequency and intensity of seizures in epileptic patients, and may also counteract some of the side effects of traditional anti-epileptic.

Does Vaping Present Any Risks?

There are a very limited number of studies covering the risks of CBD vaping, but below are two things that we believe are worth considering before starting on your vaping journey.

Thinning Agents – A major risk linked to CBD vape pens is thinning agents. Since CBD extract is usually too thick to be used for vaping products, manufacturers use a thinning agent – such as propylene glycol and polyethylene glycol. The downside of thinning agents is that when heated to high temperatures, as is the case with a vape pen, they can break down into potential carcinogenic compounds (resulting in cancer) and may cause respiratory complications.

Addiction – Whilst CBD does not have addictive properties, the process of CBD vaping by itself has been found to be addictive by a few studies. The risk of such addiction is simply that your consumption of CBD may increase, especially if you are not tracking your CBD intake closely.

Which CBD is Best for Vaping?

There are three main types of CBD used to make CBD products such as CBD oil, capsules, gummies or vape oils. Whilst full and broad-spectrum CBD is usually considered more efficient for oils and capsules as you will benefit from what is known as the “entourage effect”, most vaping oils, e-liquids or vape juices are made using CBD isolate, a crystalline powder that contains 99%+ pure CBD.

This is simply because very few studies cover the suitability of whole plant CBD for vaping or inhaling (broad and full spectrum) and several manufacturers have conducted their own toxicological assessments and have deemed whole plant hemp extract & full spectrum CBD oil unsuitable for use in the formulation of CBD e-liquid.

For this reason, the vast majority of CBD vape liquids on the market have been formulated using only CBD isolate.
