Insomnia can be exhausting, isolating, and deeply disruptive to everyday life. For some people, it becomes a long-term condition that affects physical health, mental wellbeing, work, and relationships. If you are living with persistent sleep problems and have not found relief from standard treatments, you may be wondering whether medical cannabis for insomnia could be an option.
To help you understand your options, we explain what insomnia is, why sleep problems can persist, what treatments are usually tried first, and how medical cannabis may be an option for some people who still struggle with sleep. Treatment at Medicann is always assessed on an individual basis by a qualified clinician.
You can check your eligibility for medicinal cannabis for insomnia in just a few steps.
Insomnia is a common sleep disorder that makes it difficult to fall asleep, stay asleep, or wake feeling rested. It can happen occasionally, or it can become a long-term problem.
Healthcare professionals often describe insomnia as either:
Even when people with insomnia feel tired, they may still struggle to sleep. Over time, this can affect mood, concentration, memory, and overall quality of life.
People experience insomnia differently, but common symptoms include:
When these symptoms persist, they can place strain on both physical and mental wellbeing.
Insomnia rarely has just one cause. It is often linked to a combination of physical, mental, and lifestyle factors, including:
For many people, insomnia exists alongside other long-term conditions. Managing sleep problems can sometimes help improve how those conditions feel day to day.
Most people are advised to try non-medication approaches before anything else. These focus on improving sleep habits, reducing factors that disrupt rest, and addressing underlying thoughts or behaviours that may be affecting sleep.
Sleep hygiene and routine changes
Sleep hygiene refers to everyday habits and routines that support better sleep. Small changes can sometimes make a meaningful difference over time, especially when practised consistently. Common recommendations include:
While these changes are often helpful, they may not be enough on their own for people with long-term insomnia.
Talking therapies
Psychological approaches are commonly recommended for persistent sleep problems, particularly when stress, anxiety, or low mood play a role.
Cognitive Behavioural Therapy for Insomnia (CBT-I) is one of the most widely used therapies for long-term insomnia. It focuses on identifying unhelpful thoughts, habits, and behaviours around sleep, and replacing them with strategies that support healthier sleep patterns. CBT-I can be effective, but access may be limited and progress can take time.
Prescription sleep medication
In some cases, a GP or specialist may prescribe sleeping tablets or sedative medications, usually for short-term use. These can help some people sleep initially, but they are typically prescribed with caution.
Over time, these medications may become less effective or cause side effects such as daytime drowsiness, dependency, or disrupted sleep quality. For this reason, they are not usually considered a long-term solution.
Despite trying one or more of these approaches, some people continue to struggle with poor sleep. In these cases, individuals may begin to explore other options, such as medicinal cannabis for insomnia.
Medical cannabis is sometimes prescribed for insomnia when other treatments have not provided sufficient relief.
When discussing cannabis for insomnia, clinicians focus on symptom management rather than cure. Some patients report that medical cannabis helps them:
It’s important to note that responses can vary from person to person. For this reason, a Medicann doctor will carry out a careful assessment before considering medical cannabis as part of a treatment plan, with regular reviews to monitor progress and make any necessary adjustments.
Research into medical marijuana for insomnia is ongoing but promising. Some studies and patient-reported data suggest that certain cannabinoid-based medicines may help improve sleep quality or duration for some people, particularly where sleep problems are linked to pain, anxiety, or other long-term conditions.
A 2022 clinical study examined a prescribed medicinal cannabis oil containing both THC and CBD in adults with long-term insomnia. In this controlled trial, the treatment was generally well tolerated and was associated with improvements in sleep quality and sleep duration compared with a placebo.
The study also reported improvements in night-time melatonin levels and daily functioning, with around 60% of participants no longer meeting the criteria for clinical insomnia by the end of the treatment period. The authors highlighted the importance of personalised prescribing and ongoing clinical monitoring, as responses varied between individuals.
A 2025 case series study published in PLOS Mental Health followed patients with insomnia who were prescribed cannabis-based medicinal products over an 18-month period. The study found a positive association between treatment and improvements in sleep-related symptoms and overall quality of life, based on patient-reported outcome measures, with treatment generally well tolerated.
While the authors noted that responses varied and that further high-quality clinical trials are needed to assess long-term outcomes, the findings highlight the potential role of personalised prescribing and the importance of ongoing clinical review when medicinal cannabis is used for insomnia.
Medicann clinicians carefully review the available evidence alongside your medical history and past treatments, ensuring decisions are made with your individual needs and wellbeing in mind.
There is no single treatment that works for everyone. At Medicann, our clinicians consider your symptoms, previous treatments, preferences, and overall health before recommending a suitable treatment format.
Medical cannabis prescribed through Medicann is available in the following forms:
Cannabis oils are commonly prescribed and are often used for their longer-lasting effects. Some patients ask specifically about CBD oil for insomnia, although CBD-dominant, THC-dominant, or balanced oils may be considered following clinical assessment.
Cannabis capsules offer a measured, convenient way to take medical cannabis. They may suit patients who are already used to taking oral medication as part of their routine.
Cannabis gummies provide an alternative oral option for patients who prefer not to use oils or capsules. Like other oral formats, effects tend to come on more gradually and last longer, which may be appropriate for some individuals.
Medical cannabis flower may be prescribed for use with a medical vaporiser. Vaporisation avoids smoking and allows for faster onset of effects, which may be considered where difficulty falling asleep is a particular concern. Dosing and use are carefully guided by a clinician.
Your Medicann clinician will explain the potential benefits, risks, and practical considerations of each option during your consultation, and treatment will be reviewed regularly to ensure it remains appropriate for you.
“ Quick and efficient onboarding with appropriate discussion on the medical requirements. I was simply transferring between providers so a seamless process.”
Medical cannabis is often considered as part of a wider sleep-management approach. Your clinician may also discuss:
This combined approach aims to support better rest while prioritising safety and wellbeing.
Yes, medical cannabis is legal when prescribed by a qualified doctor. Insomnia alone does not guarantee eligibility, and each case is assessed individually.
While medical cannabis is not a cure, some people report improvements in how their symptoms are managed. Individual responses vary, which is why treatment is always carefully assessed.
Sometimes yes, but a clinician will need to check first. Your Medicann doctor will review your current medications to make sure medical cannabis can be considered safely alongside them.
Is CBD oil the same as prescribed medical cannabis?
No. Over-the-counter CBD products are different from prescribed cannabis-based medicines and are not regulated in the same way. Prescribed medical cannabis is supplied under specialist medical supervision, with known cannabinoid content, consistent dosing, and ongoing clinical review, whereas non-prescription CBD products are not assessed or prescribed as medicines.
