The eustachian tube is a canal that connects your middle ear to the back of your throat and nose, with the primary job of keeping the air pressure in your middle ear equal to the outside pressure, draining mucus and secretions into the throat and blocking internal sounds.
Patulous eustachian tube is a condition in which the tube does not function as it should, staying open when it should be closed, leading to being able to hear, often in an exaggerated or booming way, your own breathing, heartbeat and voice (autophony).
What symptoms does patulous eustachian tube cause?
As well as being able to hear your bodily functions, which many patients find very distressing, symptoms also include a potentially painful, clogged sensation in the ear, dizziness/vertigo, nausea, headaches, anxiety, depression, muscle tension, and sensory overload
What is the psychological burden of living with PET?
Constantly hearing your own heartbeat, voice and breathing, as well as having outside hearing muffled or fluctuating, can cause severe distress, profound social isolation, anxiety and depression.
What treatments are currently available for patulous eustachian tube?
Many people stick to simple strategies at home to manage symptoms of patulous eustachian tube, including staying well hydrated and attempting to reset pressure equalisation by forcing exhalation against a closed mouth and nose.
Saline nasal sprays may also be prescribed. In some severe cases, surgical intervention may be required, such as inserting a ventilation tube into the eardrum, inserting custom silicone plugs or injecting fillers into the walls of the tube.
Medical cannabis can also be prescribed for patulous eustachian tube to help manage some of the uncomfortable physical and mental health symptoms.
A huge 97% of the 1,669 Releaf medical cannabis patients who took part in our 2025 patient survey, the largest of its kind at that point, reported improved quality of life.
Here's a quick overview of the main treatment options available for patulous eustachian tube:
|
Type of treatment
|
Clinical Context
|
|
Saline nasal drops
|
Although the primary purpose of saline nasal drops is to combat dryness, in the case of patulous eustachian tube these drops are used to induce temporary swelling to help seal the tube closed.
|
|
Estrogen Nasal Drops
|
Compounded, topical estrogen drops may be prescribed in some cases of patulous eustachian tube to swell the mucus membrane of the Eustachian tube.
|
|
Potassium Iodide (SSKI)
|
Oral potassium Iodide is sometimes prescribed to induce swelling and temporarily close the tube.
|
|
Prescribed medical cannabis
|
Medical cannabis can be prescribed to help manage co-occurring symptoms of patulous eustachian tube, such as nausea, dizziness and anxiety.

Can medical cannabis treatment help with my patulous eustachian tube symptoms?
Medical cannabis is generally not recommended for the treatment of patulous eustachian tube, and some studies have found cannabis can exacerbate certain symptoms. One study noted that taking nonprescribed cannabis is associated with greater odds of obstructive eustachian tube dysfunction. That said, the cannabis was likely smoked, and in the UK, it is illegal to smoke cannabis, even when legally prescribed.
When medical cannabis is taken as prescribed by a specialist clinician, some patients may find it helpful in managing the headaches, anxiety, depression, nausea and dizziness, which can go hand-in-hand with the condition.
Here’s a quick overview of what the key studies relating to patulous eustachian tube symptoms have found over recent years:
How does the endocannabinoid system relate to patulous eustachian tube?
Although no studies that show a direct link between the endocannabinoid system and patulous eustachian tube, the ECS is being increasingly researched in relation to conditions affecting the ears, nose and throat.
It’s known that the ECS plays a critical role in regulating homeostasis within the nasal, sinus cavities and tissues of the ear, helping to modulate inflammation and regulate mucus production. Inflammation, allergies, and changes in mucus consistency are common co-factors or triggers for PET symptoms. CB2 receptors in particular are studied for their potential to alleviate inflammatory pain and auditory issues.
What does the research say about cannabis and patulous eustachian tube?
So far, the very limited research looking at cannabis and patulous eustachian tube only focuses on smoking and the negative impact of that. There are broader studies looking at cannabis in otolaryngology, tinnitus being one with the most positive results.
A 2023 study found that out of 45 patients, 80% were actively taking cannabis and reported that it helped with tinnitus-related symptoms, such as dizziness, anxiety, bodily pain, and sleep disturbances.

FAQs on medical cannabis for patulous eustachian tube
Can medical cannabis cure my patulous eustachian tube?
No, medical cannabis cannot cure patulous eustachian tube, but it may help to manage co-occurring symptoms including nausea, anxiety and dizziness.
Will medical cannabis make my autophony worse?
Smoking cannabis can worsen symptoms of patulous eustachian tube, including autophony, but it is illegal to smoke medical cannabis. It’s important to take your medical cannabis prescription as advised by your Releaf clinician for the best experience.
I have tried everything my ENT offered me. Is medical cannabis worth considering?
To access a medical cannabis prescription in the UK, you need to have already tried two standard treatments. If you’ve given various treatments a go but are still having a problem with symptoms of patulous eustachian tube, medical cannabis may be worth considering.
Can medical cannabis help with the social anxiety that PET causes?
Yes, medical cannabis is known for helping with social anxiety.
A recent review of 57 studies found that, among the 13 highest-quality studies, 70% reported a positive improvement for disorders including generalised anxiety disorder (GAD), social anxiety disorder (SAD), and post-traumatic stress disorder (PTSD). Another 2019 Neuropsychopharmacology trial of CBD for anxiety found that cannabis oil containing 300 mg CBD daily significantly decreased anxiety after being taken daily for 4 weeks.
