what is the endocannabinoid system

If you are new to this series, welcome!

Here, we aim to take new patients through all the basics and get them ready to make informed decisions about their cannabis-based therapy. This is not a substitute for a consultation with a prescribing specialist, but it may help you understand the concepts better.

And what better place to continue the series than with the endocannabinoid system - a crucial biological system that regulates homeostasis and one with which cannabis compounds can interact.

Contents

What is the endocannabinoid system made up of?

There are three main pieces to the ECS puzzle:

  • Endocannabinoids - internally produced cannabinoids that bind to and activate the ECS receptors
  • Receptors - CB1 and CB2, these specialised proteins receive messages and transmit them to the cell
  • Metabolic enzymes - responsible for breaking down endocannabinoids after interacting with the receptors.

How does cannabis interact with the ECS?

Well, you might have noticed that "cannabinoid" makes up a significant portion of the term "endocannabinoid system." This biological system is named after the cannabinoids that interact with it - both the internal cannabinoids (endocannabinoids) and external ones (phytocannabinoids).

THC and CBD are phytocannabinoids - both can influence the ECS and modulate its responses.

THC binds to the CB1 receptors directly. CB1 receptors are mostly located in the central nervous system, and their activation can lead to the psychoactive effects commonly associated with recreational marijuana use. This type of activation can also have a range of therapeutic effects, helping to alleviate symptoms such as pain, nausea, and muscle spasms.

CBD, on the other hand, has a more indirect interaction with the ECS. It can enhance the activity of internal cannabinoids and block the breakdown of endocannabinoids by metabolic enzymes. This can have a balancing effect on the ECS and potentially alleviate symptoms associated with conditions like anxiety, pain, and inflammation.

Why does this matter to medical cannabis patients?

Understanding the endocannabinoid system is crucial because it helps us understand how and why cannabis-based medicines can offer such diverse therapeutic effects. By targeting specific receptor sites, cannabis compounds can address specific imbalances and promote healing, making it a powerful tool in the management of a vast range of medical conditions.

Final thoughts

So, there we have it.

A brief but hopefully informative introduction to the endocannabinoid system and how medical cannabis can interact with it to achieve therapeutic effects.

UK Savings Week: is medical cannabis affordable?

Much like all other treatment options in the UK, medical cannabis does come with costs. But, here at Releaf we do our best to balance bespoke, specialised care with affordable and accessible treatment plans, and our ever-growing patient numbers and reams of positive reviews on Trust Pilot, show we’re keeping the scales in check.

How does medical cannabis affect daily life

Medical cannabis has become increasingly accessible and accepted in recent years. However, accessing cannabis-based products - even from legal sources - can have an impact on everyday life. From medicating in public or even the comfort of your own home to driving and employment, there are many things to consider when becoming a medical cannabis patient.

When I join Releaf, will my GP find out?

Even though medical cannabis has been a full legal treatment option here in the UK since 1 November 2018, there is still a level of stigma surrounding it. It is anything but a surprise that some patients are worried about how their decision to pursue a medical cannabis prescription may affect their relationship with their general practitioner (GP).
