BackThe UK medical market demands high-THC strains
07.02.2025
Since the UK legalised cannabis for medical use in 2018, there has been an increase in patients choosing to be treated with cannabinoids. Although CBD is legal, users seem to prefer products with high THC ratios, so let’s find out why.
Medical cannabis in the UK: a rising demand
More and more patients in Great Britain are accessing medical cannabis for the treatment of different diseases. Even though users still face difficulties such as product shortages or social stigma associated with cannabis, statistics in recent years have shown a progressive increase in demand for cannabis products for medical use. It is estimated that the volume of medical cannabis patients was around 63,000 by the end of 2024, with this figure projected to double by 2028. This data makes the country one of the most dynamic medical cannabis markets in Europe.
Why do patients prefer high-THC products?
According to a report by Canna Monitor, 79% of the products prescribed in the country in recent years have been flowers, of which 93% came from high-THC marijuana strains. This preference for high-potency buds contrasts with the status of CBD products in the UK, which don’t require a prescription, and so you might think patients would prefer CBD strains given that the access to them is so much easier. Despite the legalisation of medical cannabis, bureaucratic hurdles often hinder the access of patients to products containing THC, while CBD is completely legal and can be purchased, sold, and consumed freely, provided that the products contain less than 0.2% THC. However, patients continue to choose flowers with a high THC count, so let’s analyse the reasons for this rising trend.
Medicinal effects of THC
Although the "medicinal" label has been awarded to cannabidiol (CBD) in recent years, we must not forget that this isn’t the only cannabis compound that exhibits potential therapeutic uses. Even though THC is socially stigmatised to a certain extent for being the quintessential psychoactive cannabinoid, it also showcases great medicinal potential. This is supported by the multiple studies and clinical trials that have been conducted over the last few decades. Among a number of uses, THC has been proven to be effective for the treatment of:
- Chronic pain (especially useful for the treatment of neuropathic pain). May serve as an alternative to opioids in some cases, significantly reducing side effects and the risk of substance addiction.
- Reduction of chemotherapy-induced nausea and vomiting, and an increase in appetite.
- Insomnia.
- Glaucoma (can help reduce intraocular pressure).
- Glioblastoma Multiforme (GBM), an extremely aggressive type of malignant brain tumour. Clinical trials have shown that THC may contribute to apoptosis (death of cancer cells), and may be useful as a complementary treatment.
It is important to highlight that, although THC is a cannabinoid with proven therapeutic properties, its medicinal use must be done under the supervision of a doctor. That’s why legalisation is so important, as it ensures safe and effective access to cannabis treatments for patients.
Bureaucratic hurdles and the preference for high-THC marijuana varieties
As explained above, although the therapeutic benefits of THC are undeniable, the preference of UK patients for high-potency strains may also be influenced by other factors. Nowadays, there are strains with moderate THC:CBD ratios (1:1, 1:2, etc.) whose effects are more sustainable. One might think that patients choose these genetics because they prefer to avoid the side effects of THC (dry mouth, anxiety, paranoia, etc.). One of the reasons that could explain the preference for high-potency products is that a large part of the prescriptions is issued in private clinics, with all the associated costs that this implies. This could influence the preference for products with higher THC levels, as users would seek to maximise the therapeutic effects based on the cost alone.
Which marijuana strains are higher in THC?
Thanks to the legalisation of medical cannabis in most European countries, patients now have access to specific genetics that are becoming more and more adapted to their therapeutic needs. Today, seed banks work hard to create new specific cultivars with different cannabinoid and terpene profiles to cover a wide spectrum of uses. For this reason, our team of breeders at Linda Seeds have created various cannabis seeds that have taken the scene by storm, especially among those looking for high-flying potency. If you’re into high-THC strains, pay close attention…. These are some of the gems that you’ll find in our catalogue:
