Can medical cannabis be prescribed for psoriasis in the UK?
Yes, in the UK medical cannabis may be prescribed for psoriasis, but that prescription must be issued by a specialist listed on the GMC Specialist Register. It is not considered a first-line treatment option for psoriasis and will not cure psoriasis or treat the underlying causes, but can be considered for eligible patients when conventional approaches have not provided sufficient symptom relief.
Medical cannabis is not prescribed to replace conventional treatment options, but to sit alongside them. Keeping your GP and dermatology/rheumatology care team informed helps to make sure that every part of your treatment works together.
Prescribed medical cannabis versus over-the-counter CBD oils and creams
Over-the-counter CBD oils, creams, shampoos, and other non-prescribed CBD options are consumer wellness products, not prescribed medicines for psoriasis. They should not be seen as a substitute for specialist assessment or an agreed-upon treatment plan from your dermatologist.
Prescribed medical cannabis is different.
It is supplied through a regulated pharmacy after a specialist has reviewed your full medical history, current treatment options, and overall health needs and goals.
Your UK medical cannabis treatment is clinically overseen with regular follow-up consultations, allowing your specialist to have the ability to monitor your response and make changes where needed or appropriate.

Which psoriasis symptoms might medical cannabis help with?
For eligible patients, the question is not only how visible psoriasis may be, but also how its symptoms can affect their day-to-day lives.
Your prescribing specialist will consider whether medical cannabis could help manage your particular symptoms, rather than just the underlying inflammatory processes. Medical cannabis won't help control every single psoriasis symptom, but it may help with the following:
CBD and THC for psoriasis: what is the difference?
THC and CBD are the two most well-known cannabinoids produced by cannabis plants, and for good reason. While they are just two of over 110 cannabinoids that have been isolated from Cannabis sativa L. species (which includes both cannabis and hemp plants), they are produced in greater abundance than any of the minor cannabinoids.
Both have the ability to interact with the endocannabinoid system, but do so in quite different ways. The endocannabinoid system helps regulate a wide range of bodily functions, including pain signalling, sleep, mood, and immune/inflammatory activity, among many others.
Both cannabinoids also have an impact on separate receptor systems, so the picture is far more complex than their endocannabinoid system interactions alone.
|
THC
|
CBD
|
|
How it acts
|
Activates cannabinoid receptors, particularly CB1 receptors in the brain and nervous system, and CB2 receptors involved in immune signalling. It also affects pain, dopamine and GABA signalling.
|
Has a less direct effect on cannabinoid receptors. It can influence serotonin, adenosine and TRPV receptors, which are involved in mood, inflammation and pain signalling.
|
|
What this may mean for psoriasis-related symptoms
|
May be relevant to pain, sleep disruption and the wider stress of living with a chronic condition.
|
May be relevant to discomfort, itch and inflammatory signalling, but research does not show that CBD treats psoriasis itself.
|
|
Intoxicating effects
|
Can cause intoxication at higher doses. Your specialist will work with you to find a dose size that offers therapeutic benefits without intoxication.
|
Does not produce the intoxicating effects associated with THC.
|
|
How a specialist approaches it
|
May be included in a prescription where the potential symptom-management benefits are judged to outweigh the possible drawbacks.
|
May be prescribed alongside THC or on its own, depending on your symptoms, treatment history and overall health.

What about scalp psoriasis?
Psoriasis of the scalp is one of the more common forms the condition takes, and it can be extremely difficult to live with. The persistent itching, soreness, thick scale, and flaking can be quite difficult to disguise, while scratching can make the scalp feel very irritated.
Standard treatment for psoriasis of the scalp mostly focuses on the scalp itself with medicated shampoos, topical treatments, and support from both your GP and dermatologist where needed.
Medical cannabis will not be prescribed to clear scalp plaques, reduce scale, or treat hair loss, but it may help to soothe any itching, improve sleep, and reduce chronic soreness. That type of almost never-ending itch and soreness can also cause sleeplessness, anxiety, and depression if left untreated.
Psoriasis, psoriatic arthritis and joint pain
An estimated 25% of people with psoriasis develop psoriatic arthritis. This is an inflammatory condition that can cause joint pain, swelling, stiffness, and fatigue. It is very different from general skin psoriasis, and needs assessment by a GP or rheumatologist, particularly if you have persistent joint symptoms, swollen fingers or toes, or stiffness that is worse in the morning.
What the evidence says, and any risks to be aware of
Research into medical cannabis specifically for psoriasis and psoriatic arthritis is still in the early stages, but is beginning to give a clearer picture of where it may have a role in symptom management. Early real-world data show patients report improvements in pain, sleep, and day-to-day quality of life, while controlled CBD studies have produced more mixed results.

Study
|
What the research found
|
Important context
|
|
Oral CBD oil trial in psoriasis
|
28 adults with chronic plaque psoriasis received oral CBD oil or placebo for 12 weeks. CBD did not produce a significant change in psoriasis severity, although itch improved at Week 8 and time taken to fall asleep reduced at Week 6.
|
Both improvements were temporary and not sustained by Week 12. This was a small trial of CBD oil, not prescribed THC-containing medical cannabis.
|
|
Synthetic CBD trial in psoriatic arthritis and hand osteoarthritis
|
129 participants received synthetic CBD or placebo for 12 weeks. CBD did not improve pain, sleep, anxiety or depression scores more than placebo.
|
This was a stronger randomised trial, but included people with hand osteoarthritis as well as psoriatic arthritis.
|
|
UK Medical Cannabis Registry study
|
82 people with inflammatory arthritis, including psoriatic arthritis, reported statistically significant improvements in pain, sleep and quality-of-life measures over 12 months after beginning prescribed cannabis-based medicines.
|
This was an observational case series, so it can identify an association but cannot prove that prescribed cannabis caused the changes.
|
|
Releaf patient survey
|
10 of 12 respondents who mentioned psoriasis rated their prescribed medical cannabis treatment as moderately, very, or extremely effective.
11 of 12 reported some improvement in quality of life, while 10 of 12 reported improvement in everyday tasks and 9 of 12 in work or study.
|
This is a small, self-selected group. It is useful patient feedback, but not clinical evidence and should not be used to predict another person’s outcome.
|
Like all prescribed medications, medical cannabis can cause certain side effects and interact with other prescribed medicines. All of this will be taken into account by your prescribing specialist before any recommendation for your treatment is made.
