Here, we have a brief look at the different methods of using CBD, and how each method affects bioavailability

One of the first things to consider is bioavailability, this is a term used to describe the degree and rate at which a substance is absorbed into the bloodstream. The bioavailability of CBD varies based on the consumption method and concentration of CBD in the product you are using. So let us have a brief look at the different methods of using CBD, and how each method affects bioavailability.

Oral Ingestion

This method means ingesting either Capsules or Edibles so that it can be metabolised by your gastrointestinal system. Ingesting CBD usually takes longer to feel compared to other methods, particularly sublingual and vaping. You can usually feel the positive effects within one hour after oral consumption with a similar effective length of sublingual application usually lasting 4 to 6 hours.

Other factors can affect this rate of absorption, clearly, if you are chewing a gummy CBD will be partially absorbed sublingually prior to swallowing, your body weight, metabolism, and stomach content will also affect absorption.

Sublingual Consumption

Involves either spraying or placing the CBD oil under the tongue and usually holding it there for 30 seconds or so after which you would swallow the residual, there are a lot of mucous membranes under your tongue, all of which have a permeable layer covered in tiny blood vessels. These vessels allow for the quick absorption of Cannabinoids directly and quickly into the bloodstream. The positive effect can be felt in under 5 minutes and can typically last up to 4-6 hours. Sublingual consumption is one of the most popular methods of administrating Cannabinoids.

Vaporising (know as vaping)

This method gives an almost instantaneous effect its quicker that sublingual application, but the effects have a shorter lifespan than all the other applications. Much like the mucus membranes under the Tongue, there are permeable membranes in your lungs. These allow the vaporised CBD to become absorbed directly into the bloodstream in 60seconds or less. Typically, you can begin to feel the effect within 30 to 90 seconds however it usually only lasts 2 to 3 hours.

Topicals (creams and balms)

This is different in that the CB is applied directly to the skin in the area that’s affected and/or required. This can be a lotion, cream or balm. When using topicals the rate of bioavailability does not apply because the CBD only reached the cannabinoid receptors just below the dermal layer.

Water-based CBD

The main advantage of water-soluble CBD is that your body absorbs a much higher percentage of the cannabinoids and terpenes available in the product, it has been suggested that almost 100% bioavailability is obtainable. This would suggest that you could take less water-based CBD product as opposed to the CBD oil and obtain the same effect, and therefore the financial cost could be reduced.


PlantEd Collective

“There is a change in image here from cannabis being associated with ‘teenage boys on BMX bikes’ to ‘women advocating for wellness’ that brings about a different energy with which to step forward”

Women unite to provide education to cannabis and plant medicine consumers

Five women, five different health conditions, five approaches to wellness – PlantEd Collective are a female-led team with experience spanning a range of specialities, such as: education, the arts, activism, health and social care, patient advocacy, cannabinoid therapy and movement medicine.

They come together with the collective aim to create dialogue and engagements using complementary specialisms, building a platform of education around wellness, medicinal plants and herbology at a time where society is actively stepping away from the synthetic. PlantEd’s mission is to provide a space for those who are, instead, looking to restore their relationship with natural treatment methods, in line with the very latest research from around the world.

Why do you exist?

Each of the PlantEd team bring very different experiences, as we span such a broad range of specialisms. As cannabis consumers, activists, educators, yoga practitioners and boundary breakers, we understand this space and, most importantly, we understand the consumer needs and barriers to accessing information.

Cannabinoid consumers in the UK are awash with information that is often misleading and fraught with challenges. For example, there are barriers to CBD suppliers sharing information about medicinal benefit due to regulation, and there are legal barriers to discussing medicines containing THC.

The information that makes it to UK consumers is often outdated and not practical. There currently is no safe, reliable place for consumers to digest the latest science, or educate themselves from a place of independence.

Our not-for-profit scheme hopes to tackle this head-on. Whilst many other organisations are focused on educating policymakers and medical professionals in a top-down approach, we would like to be able to fill the gap in a ground-up approach, building knowledge within the consumer community so that choices are made from a place that is informed.

We aim to tackle this by:

  • Providing access to digestible summaries of scientific developments.
  • Enlisting the engagement of high-profile researchers and developers to bring conversational content via accessible podcasts.
  • Designing short courses to enable consumers to teach themselves and increase the knowledge base from the ground up.
  • Providing resources for families and children to instil high-quality education and dispel the tension that so often exists in a family when dealing with stigma.
