Treat OCD with Medical Cannabis
Obsessive-compulsive disorder (OCD) is a serious and often misunderstood mental health condition. Medical cannabis is sometimes prescribed privately in the UK for certain mental health conditions, including OCD, when conventional options have not provided sufficient relief.
This page explains what OCD is, what causes it, how it is usually treated, and how medical cannabis for OCD may be considered as part of a specialist-led, regulated care pathway.
What is Obsessive-Compulsive Disorder (OCD)?
OCD is a form of neurodivergence, much like autism and ADHD, where the brain functions differently to a neurotypical one and is characterised by a cycle of obsessions and compulsions.
Obsessions are intrusive thoughts that repeatedly enter the mind and cause significant anxiety or distress. Compulsions are repetitive behaviours or mental acts that a person feels driven to perform in response to these obsessions, often in an attempt to reduce anxiety or prevent a feared outcome. It may temporarily relieve the anxiety but it does soon return, starting the cycle again.
In everyday language, OCD is frequently misunderstood and often used to describe being organised or a perfectionist. While compulsions can sometimes involve tasks like cleaning or tidying, those behaviours are not driven by preference but instead a fear that if it isn’t completed, the intrusive thought will happen.
What causes OCD?
There is no single cause of OCD. Research suggests it develops due to a combination of biological, psychological and environmental factors. These may include:
Differences in brain chemistry, particularly involving serotonin
Genetic factors
Learned behavioural patterns
Stressful, traumatic, or life-changing events.
Common Symptoms of OCD
As mentioned above, OCD is a cycle of obsessions and compulsions, which can vary from person to person.
It’s normal to have an intrusive thought but if it dominates your thinking and causes anxiety, it may be an obsession. Some common obsessions include:
Fear of contamination from dirt, germs, viruses, etc.
Fear of accidentally harming someone else
A fixation on symmetry and orderliness
Excessive concern about the body or physical symptoms
Fear of violating a religious or moral doctrine
Sexual thoughts
A need to hoard old possessions
Thoughts about violence and aggression.
To reduce distress caused by obsessions, you may feel like you have to do repetitive things, known as compulsions. Examples of compulsions include:
Rituals, e.g. washing your hands excessively or touching things in a certain order or at a certain time
Repetitively checking things, e.g. doors and windows to make sure they’re locked or your route to work to make sure you didn’t cause an accident
Correcting thoughts, e.g. repeating words out loud or in your head, counting to a certain number or ‘neutralising’ a negative thought with a positive one
Constantly seeking reassurance, e.g. by repeatedly apologising to people or asking other people to tell you everything is alright
Rumination, e.g. thinking about the same over and over, or trying to ‘fix’ your thoughts by thinking about what they mean
Avoidance, e.g. avoiding situations or people that cause anxiety, or procrastinating.
Standard Treatments for OCD
In the UK, first-line treatments for OCD typically include:
Cognitive behavioural therapy (CBT), mainly exposure and response prevention (ERP)
Antidepressant medication, most commonly SSRIs
OCD support groups.
How Medical Cannabis may help with OCD Symptoms
Medical cannabis is typically available as CBD, THC or a combination of the two. It is not currently available through the NHS for OCD but can be prescribed by a specialist doctor in the UK. CBD and THC are both cannabinoids, which interact with the endocannabinoid system (ECS). The ECS plays a role in a number of key functions in the body, including:
Anxiety regulation
Stress response
Emotional processing
Sleep patterns.
Therefore, taking cannabis for OCD may help some patients manage:
Persistent anxiety linked to obsessive thoughts
Heightened stress and emotional distress
Sleep problems that exacerbate symptoms
Responses vary, and not everyone will benefit. Careful assessment and monitoring are essential if you take medical cannabis.
What Type of Cannabis Treatment is used for OCD?
There is no single recommended product for OCD. Treatment is tailored depending on your personal circumstances. You could be prescribed CBD, THC or a combination of both. There are also a number of formats available, including cannabis oil, flower, capsule and pill.
In your initial consultation, the clinician will assess whether you’re eligible and if so, what method may work best for you, whether that’s THC pills or CBD oil for OCD treatment.
Combining Medical Cannabis with other Treatments
Before taking medical cannabis, it’s important to check interactions with other medications. For example, antidepressants (SSRIs) are a common treatment for OCD. Taking CBD or THC may increase the concentration of SSRIs you take, increasing risk of side effects. Your clinician will assess what medication you already take and the interactions with medical cannabis before prescribing it to you.
Medical cannabis can work well with non-pharmalogical treatments, however, such as talking therapy or changes to lifestyle.
Patient Testimonials
“After being left without medication by another clinic, I decided to switch to Medicann. Best decision I made, they were so quick and efficient in their replies and within days I've received my prescription. Communication afterwards has been equally as quick and the fast time frame (26hours total) from requesting my prescription to delivery is amazing.”
