What is Medical Cannabis

What is Medical Cannabis (Cannabis Based Medical Products)

What is Medical Cannabis? What is it used to treat?

Cannabis Based Medical Products (CBMPs) or Medical Cannabis are medications derived from the cannabis plant, containing cannabidiol (CBD) and/or Tetrahydrocannabinol (THC – which is the psychoactive substance in cannabis). In the UK medical cannabis has been legal since 2018 for the treatment of psychological, neurological, and chronic pain conditions as well as, palliative and/or end of life care: for sake of brevity a full list of conditions treated in the UK is highlighted in eligibility section of this website.

What’s the eligibility criteria?

With cannabis based medical products (CBMPs) being unlicenced, the census would be for patients to evidence unmet clinical needs i.e., their health is not improving despite having ongoing treatment or interventions via conventional healthcare services. It is important for all patients to recognise that due to cannabis containing a psychoactive substance, for the safety of potential patients, if you have any of the diagnosis listed in the exclusion criteria, you will not be eligible. We would advise these patients to liaise with their consultants at the NHS and explore an alternative treatment method to support their health needs.

Patients have a right to a second opinion, provided they do not have any counterindications listed in the exclusion criteria below. Patient’s must be over 18 years of age.

Exclusion Criteria?  

Like all medications, CBMPs is not advisable to use if you struggle from one of the following: –

  • Suffer with high BP (If this is not stable)
  • History of psychosis
  • Diagnosis of schizophrenia
  • Heart condition (Which has NOT been stable for 6+ months)
  • Pregnant or breast-feeding

What are the side effects of medical cannabis?

Side effects of CBMPs include:

  • Drowsiness
  • Confusion
  • Imbalance
  • Euphoria
  • Diarrhea
  • Dry mouth
  • Anxiety and/or Depression
  • Heart Palpitations
  • Psychological Dependence
  • Tolerance
  • Cannabis hyperemesis syndrome (CHS)

Adverse reactions include:

  • Headaches
  • Migraines
  • Nausea
  • Vomiting
  • Diarrhoea

If you experience an adverse reaction, it is important that you report your symptoms to the MHRA via yellow card, who are the medicines and healthcare products regulatory agency. To report a yellow card, please follow this link and fill out the form: Yellow Card | Making medicines and medical devices safer ( It is also vital that you inform your clinic, to ensure this medication is not prescribed to you again in the future.

Cannabis dependence:

Cannabis dependence is known clinically as cannabis use disorder, and user’s of any form of medicines, including medical cannabis are prone to psychological dependency.

Signs of Psychological dependence include:

  • Not using medications as prescribed -> using more than required or larger dosages and/or more frequently
  • Withdrawal
  • Developed a tolerance and require more
  • Failed repeated attempts to control or stop use
  • Physical or psychological concerns related to use (i.e., respiratory concerns or fluctuation in mood)
  • Missing relevant appointments or work to use
  • Craving for purposes other than prescribed

If you experience any of the following, please get in touch with your prescriber, so that they may manage this concern accordingly.

Cannabis Hyperemesis Syndrome (CHS)

Cannabis hyperemesis syndrome, also known as cannabinoid hyperemesis syndrome, can affect people who are exposed to prolonged, high doses of cannabis: this can also occur with medical cannabis use.

Signs of Cannabis Hyperemesis Syndrome include:

  • Intense nausea and vomiting
  • Projectile vomiting (can happen without warning, up to 5x an hour)
  • Extreme Diarrhea
  • Lack of appetite
  • Weight loss

Although this is uncommon, if you experience any of the following, please reduce use or stop where possible and urgently alert your prescriber. If symptoms are uncontrollable, please seek urgent medical intervention as you are at risk of dehydration.

Monitoring BP / Warfin prescription

Medical cannabis can for some people cause heart palpations, it is important that people with a history of high blood pressure or a heart condition to be mindful of this, particularly those on warfarin as cannabis can impact the liver enzymes, interacting with other medications. It is important that you work alongside your GP and relevant health care professionals to adequately address your heart.

If you are someone who meets this criterion, regularly monitoring your blood pressure would aid in ensuring your safety and enables you to appropriately reach out for support.

Blood pressure guidance:

Low 90/60 or below Inform GP and clinic, if unwell seek medical attention
Ok 90/60 – 140/90 Continue to monitor – update clinic at FUP appointment
Raised 141/91 – 179/119 Raised, monitor and inform GP and clinic
High 180/120 or more Significant risk, needs urgent review – update GP and clinic

The Cannabis Plant: Nature’s Gift Unveiled

Cannabis Bud AI Generated Image


The cannabis plant, scientifically known as Cannabis sativa, has been a part of human history for millennia, revered for its versatility and medicinal properties. In this comprehensive blog, we will explore the fascinating anatomy, life cycle, pollination methods, defence mechanisms, habitats, and diverse types, shapes, and colours of the cannabis plant. Let’s embark on this journey of discovery and unravel the enigmatic world of cannabis.

Anatomy of the Cannabis Plant

The cannabis plant is a hardy, dioecious flowering plant, meaning it has separate male and female reproductive structures. Below is a simple table illustrating the basic anatomy of the cannabis plant:

Plant PartFunction
LeavesPhotosynthesis and transpiration
StemsSupport, nutrient transport, and storage
Flowers (Buds)Reproductive structures containing cannabinoids
SeedsReproduction and dispersal of the species
RootsAnchoring, nutrient and water absorption

1. Cola:

The Cola refers to the cluster of buds at the top of the female cannabis plant. It contains high concentrations of cannabinoids, such as THC and CBD, making it a crucial component for medical cannabis production. Colas are carefully cultivated and harvested for their therapeutic properties, contributing to the medicinal benefits of the plant.

2. Sugar Leaf:

Sugar Leaves are the small, sugar-coated leaves that surround the Cola and other buds. These leaves contain trichomes, which are resin-producing glands responsible for synthesising cannabinoids and terpenes. Sugar Leaves are also utilised in medical cannabis preparations due to their cannabinoid-rich content.

3. Pistil and Stigma:

Pistils and Stigmas are the reproductive structures of the female cannabis plant. The Pistil consists of the Stigma, which is a hair-like structure designed to capture pollen during pollination. While cannabis growers typically remove male plants to prevent seed development, these female reproductive components play a significant role in medical cannabis production as they are rich in cannabinoids and other beneficial compounds.

4. Trichomes:

Trichomes are tiny, crystal-like structures that cover the surface of cannabis plants, including the Cola and Sugar Leaves. These structures are the powerhouse of medicinal compounds, housing a majority of the cannabinoids and terpenes responsible for the therapeutic effects of medical cannabis. Trichomes are carefully preserved during harvesting to ensure maximum medicinal potency.

5. Fan Leaf:

Fan Leaves are the large, fan-shaped leaves that emerge from the cannabis plant’s branches. While they contain minimal cannabinoid content, they play a crucial role in the photosynthesis process, providing the plant with the energy it needs to produce therapeutic compounds. Fan Leaves also contribute to the overall health and vigour of the medical cannabis plant.

6. Bract and Calyx:

Bracts are modified leaves found at the base of each Cola, while Calyxes are small, cup-like structures that encase the cannabis seeds when pollinated. While Bracts and Calyxes have limited cannabinoid content, they are essential components for medical cannabis growers as they protect and support seed development, which is crucial for strain preservation and breeding purposes.

Life Cycle of the Cannabis Plant

The life cycle of the cannabis plant consists of several stages, each crucial for its survival and propagation. Let’s take a look at the key phases:

  1. Germination: The life cycle begins with a seed, which germinates when exposed to water, light, and suitable temperature conditions.
  2. Vegetative Stage: During this phase, the plant focuses on vegetative growth, producing leaves and stems. It requires ample light, nutrients, and water.
  3. Flowering Stage: As the plant matures, it enters the flowering stage. Female plants develop buds containing cannabinoids, while male plants produce pollen for pollination.
  4. Pollination: Cannabis plants employ various pollination methods, primarily wind pollination or insect-facilitated pollination.
  5. Seed Production: If pollination is successful, female plants produce seeds within their buds.
  6. Death and Decay: After seed production, the plant completes its life cycle and eventually dies or goes dormant.

Pollination Methods of the Cannabis Plant

The cannabis plant has developed different strategies for pollination. The two main methods are:

  1. Wind Pollination: In this method, male cannabis plants release pollen grains into the air, which are carried by the wind and may land on female flowers, leading to fertilisation and seed production.
  2. Insect-Facilitated Pollination: Some cannabis strains have co-evolved with insects like bees and butterflies to facilitate pollination. These insects visit male flowers, collect pollen, and transfer it to female flowers, aiding in fertilisation.

Defence Mechanisms of the Cannabis Plant

To protect itself from predators and environmental stressors, the cannabis plant deploys various defence mechanisms. These include:

  1. Cannabinoids: Cannabis plants produce a range of cannabinoids, including THC and CBD, which can deter herbivores and insects.
  2. Trichomes: Tiny hair-like structures on the surface of cannabis leaves and buds secrete resin, which contains cannabinoids and terpenes that can repel pests.
  3. Smell: The strong aroma produced by cannabis plants can attract pollinators and beneficial insects while repelling potential threats.
  4. Adaptability: Cannabis plants can adjust their growth patterns and chemistry in response to environmental conditions, enabling them to survive in various habitats.

Habitats of the Cannabis Plant

The cannabis plant is remarkably adaptable and can thrive in diverse habitats, including:

  1. Outdoor Environments: Cannabis grows well in temperate climates with long growing seasons, such as parts of North America, Europe, and Asia.
  2. Indoor Cultivation: Controlled indoor environments with appropriate lighting, temperature, and humidity can also support cannabis growth.
  3. Greenhouses: Greenhouses offer a balance between outdoor and indoor cultivation, providing a controlled environment with natural light.

Various Types, Shapes, and Colours of Cannabis

Cannabis exhibits a wide array of types, shapes, and colours, influenced by factors such as genetics, cultivation techniques, and environmental conditions. Below are some common cannabis types:

SativaTall, slenderLight green, orange, yellow
IndicaShort, bushyDark green, purple
RuderalisSmall and ruggedPale green
HybridsVaries depending on mixCombination of colours


The cannabis plant is a remarkable botanical wonder, with a rich history and countless applications in various fields. Understanding its anatomy, life cycle, pollination methods, defence mechanisms, habitats, and diverse characteristics can foster appreciation for this extraordinary plant. Whether it’s for medical purposes, recreational use, or industrial applications, the cannabis plant continues to intrigue and amaze humanity, reminding us of the wonders of nature.

Terpenes: Unveiling Nature’s Aromatic Healers in Cannabis


Terpenes, the aromatic compounds found in various plants, including cannabis, have gained attention for their potential therapeutic benefits. These natural wonders not only provide delightful scents and flavours but also contribute to the entourage effect, enhancing the medicinal properties of cannabinoids. In this comprehensive guide, we will delve into the world of terpenes, exploring their diverse benefits and highlighting their presence in cannabis strains.

What are Terpenes?

Terpenes are organic compounds produced in the resin glands of plants, including cannabis. They are responsible for the distinctive aromas and tastes of different strains. In addition to their sensory appeal, terpenes offer a range of therapeutic effects. More than 200 terpenes have been identified in cannabis, each with its own unique characteristics and potential health benefits.

Natural Occurrence of Terpenes

Terpenes are not unique to cannabis; they are widespread in the plant kingdom and can be found in various fruits, vegetables, herbs, and flowers. These compounds are synthesised in the resin glands of plants and serve essential ecological functions. In nature, terpenes act as attractants for pollinators, deterrents for predators, and defence mechanisms against microbial and insect attacks. The diverse aromas and flavours emitted by plants owe their existence to the rich variety of terpenes present. From the soothing scent of lavender to the zesty aroma of citrus fruits, terpenes create an aromatic symphony in the natural world.

Historical and Cultural Influence of Terpenes

Terpenes have played significant roles in human history and culture. For centuries, people have utilised the aromatic properties of plants containing terpenes for various purposes. In ancient civilisations, plants rich in terpenes were used in traditional medicine, perfumery, and religious rituals. The Egyptians used myrrh, a resinous plant containing terpenes, in embalming processes. The ancient Greeks and Romans valued the uplifting effects of terpene-rich plants like mint and rosemary. Throughout history, the cultural significance of terpenes has extended to culinary arts, where herbs and spices infused with terpenes add depth and flavour to dishes. Today, terpenes continue to shape the world of fragrance, food, and medicine, providing us with an appreciation of nature’s aromatic wonders.

Harnessing Terpenes for Medicinal Use

For medical cannabis patients, understanding terpenes is essential for optimising treatment. By selecting strains with specific terpene profiles, patients can tailor their cannabis-based therapies to suit their individual needs. Consulting with a knowledgeable healthcare professional or pharmacist experienced in medical cannabis can provide valuable guidance in strain selection.

Terpenes have shown promise in various areas of health and wellness. When combined with cannabinoids like THC and CBD, they work synergistically to enhance the therapeutic potential of cannabis. Let’s explore some of the prominent terpenes found in cannabis and their potential medicinal benefits:

What Do Patients Want?

In this post we discuss the products currently prescribed to patients and strains that patients would like to see on the medical cannabis market. We put together a short questionnaire to ask patients what products they are prescribed and for what condition, how they feel about the products prescribed to them and if it is beneficial for their condition, what strains they are familiar with and what condition do they benefit. We also asked patients to provide some feedback on their experiences as a Medical Cannabis Patient. We received 21 responses from patients, here are the results:

Conditions Identified
Neuropathic Pain8
  • Ankylosing Spondylitis Anxiety
  • Insomnia
  • Neuropathic Pain Colitis
  • PTSD
  • Depression
  • ADHD
  • Chronic Pain
  • Migraines
  • Hypermobile Ehlers-Danlos Fibromyalgia
  • Nerve Pain
Medical Cannabis Products
Graph Showing What Products Patients Are Prescribed.

From this graph we can identify 2 products commonly used among patients. Khiron 18-22/1 THC Hindu Kush & Adven EMT 1 19% THC (Cairo – Unknown Strain). ‘Khiron Hindu Kush 18-22/1 THC CBD Flos’ was commonly found among patients with Neurological Pain and Anxiety whereas ‘Adven Flos EMT 1 19% THC’ was used for most of the conditions mentioned. Within the Khiron product patients can identify the strain as Hindu Kush, whereas with ALL Adven products the patients are left unaware of the strain name and pretty much any other information.

What Patients Want

List of Strains Preferred By Patients Not On The Medical Market;

  • Blue Cheese (Sleep, Depression, Anxiety)
  • Cheese
  • Granddaddy Purple (Anxiety, Pain)
  • Northern Lights  (Pain, Sleep)
  • Biscotti (Anxiety)
  • Zkittles
  • Gorilla Zkittles
  • Strawberry Cough (Anxiety)
  • Strawberry Haze
  • Strawberry Diesel
  • Do-si-do (Rumor there was an Adven (EMT 6) of this same strain)
  • Girl Scout Cookies (Anxiety)
  • Sour Diesel (Anxiety, Pain)
  • Green Crack (Anxiety)
  • Purple Punch
  • OG Kush (Sleep, Depression, Anxiety, Pain)
  • S5 Haze (Sleep, Depression, Anxiety)
  • Chocolate (Sleep, Depression, Anxiety)
  • Pink Panties
  • Stardawg (Pain, Anxiety)
  • Super Silver Haze
  • Train Wreck
  • Afghan (Pain, Sleep)
  • Afghan Kush (Pain, Sleep)
  • Rhino Ryder (Pain, Sleep)
  • Bubba Kush (Pain, Sleep)

Patients have emphasised that there are so many strains that they could list although the list is still quite long. No patient was able to identify products from any medical market so there are no CoA with these products they have tested. The 2 most common strains mentioned were Granddaddy Purple (5x) and Stardawg (4x). Grandaddy Purple is best known for treating pain, stress, insomnia, appetite loss, and muscle spasms. Although Stardawg can help treat stress, fatigue and anxiety disorder, patients with pain issues also noted that it helped them too.

Types Of Products

We asked patients what type of products they would benefit from as we received a diverse result. Most patients identified that they benefit mostly from High THC/Low CBD Flower and also identified that Hashish is also beneficial. Currently patients are unable to get Hashish prescribed to them, in the Australian market there is “Bubble Hash” which can be made without additional chemicals or gasses. The Bubble Hash found in the Australian Market is called CannaTrek T55 (Bubble Hash Topaz), from the name it indicates a strong medication. The other products patients would like to see were Pollen Hash.


Examining the feedback from patients it is quite obvious that the consistency of medication we all receive is poor and is proving to affect patient’s treatments. Although medical cannabis has been available since 2018, 3.5 years on and we are still experiencing slow development and improvements to the products we are prescribed. The variety that’s available at the moment is not diverse enough and patients have to be okay with whatever they get prescribed, this causes patients to experience ‘strain lock’, in turn affecting their treatment.

Cost of medication is also something highlighted by patients. The cost is always compared with the illicit market and in doing so we can see that Medical Cannabis is still very expensive, especially for patients who are unable to work due to their health and rely on benefits. Key compounds in cannabis that patients feel are not being taken seriously are ‘Terpenes’. Patients have said that due to the way the product goes through drying, curing, storage and steralisation patients say they can notice a significant decrease in quality and standards.

In conclusion, standards need to improve and prices need to match that of the quality and that of patient needs before entering the market. More products are needed that patients are familiar with and of those products that patients are aware benefit their conditions. We also need more variety of products, including Bubble Hash and Vape Cartridges to help patients who are unable to benefit from Flower, Oils or Capsules. ‘High THC/Low CBD’ flower is most common but there is still a need for ‘Balanced’ flower too.

Patient Feedback
The irradiation process destroys any smell/terpenes from the flower and really does let the whole market down.
Irradiated seems to remove the taste as well as the smell and most of the time the products seem to come as they have been left in storage for too long. Recent batch of EMT 1 has improved because of new method of storage, this has reflected on the effects too!
The frustration for me is the process, there seems like a lot of red tape to make this efficient. Typical “make it hard” strategy from the government who make things a lot harder than it needs to be. Risk assessment gurus who have to make sure there is a safe way to achieve an easy win! Sadly until this is more second nature this will be the case with the UK. It seems also that lots more would benefit from the medicine however this isn’t possible for those who don’t work! Making a system that’s only available for those who are in a position to pay! This in itself discriminates those who can’t afford it and is again a government incentive that only works, as there is money to be made through it. Other countries seem to have this sorted and even have recreational use in hand! Sadly again with the UK we are behind in thinking we know best! When I’m actual fact they are just over cautious as usual and are blind sighted with the fact that legalisation would not only reduce police time! But would create a revenue to assist in these hard times of recession! And would also satisfy the public in regards to allowing it to be legal.
I am currently allowed 30g of flower per month (1g per day) but I actually use double that on average, the prices are actually higher than black market flowers and they don’t have the quality of it yet.
The flower dose not need to be irradiated to meet standards a d its proven by many this needs to stop also the flower needs to be hand trimmed not machines as its destroying the end product and we should be able to pick and choice a flower to what we want not be subject to one type
The Hindu Kush I get prescribed is good for pain relief but I need large doses. Not sure if it’s the lack of terps due to sterilisation or perhaps lack of potency in terms of THC.  I can imagine a tolerance will quickly build up. But for now after just 1 prescription it works well enough.
I appreciate the prescription so much and recognise were early in the process but disappointed at the general standard of products and lack of choice.
The products are improving but it’s crazy to think that there is a high standard market across the globe and we are only importing products that are only just improving… where was the R&D? Irradiation, incorrect curing and storage certainly affect the terpenes but it’s never a concern to the clinicians. We don’t even get Product Information Leaflets with our medicines.
Products are way too expensive for patients without jobs due to disability
