CBD and Tinnitus: What Does the Research Actually Show?

People living with tinnitus sometimes search for CBD in the hope that it might reduce ringing, buzzing or other unwanted sounds. But current research does not establish CBD as a treatment for tinnitus.

There is scientific interest in the endocannabinoid system and auditory signalling, but the evidence available so far is limited. Some animal research has produced results that actually argue for caution rather than suggesting cannabinoids reduce tinnitus.

It is also important to distinguish between cannabis, THC, combinations of THC and CBD, and purified CBD. Research involving cannabis or THC should not be presented as evidence about a CBD-isolate product.

What is tinnitus?

Tinnitus is the perception of sounds that do not come from an external source. People may describe ringing, buzzing, humming, hissing, whooshing or other sounds in one or both ears or in their head. It can be intermittent or persistent.

Tinnitus is often associated with hearing loss, although there are many possible contributing factors and sometimes no obvious cause is found.

Because tinnitus can affect sleep, concentration and emotional wellbeing, it is understandable that people look for products that might help.

That does not, however, mean that CBD has been shown to treat it.

Can CBD help tinnitus?

At present, there is no good evidence that an ordinary CBD product reduces tinnitus.

A published review examining the relationship between cannabinoids and tinnitus looked at animal research, survey data and the limited clinical evidence available. It concluded that there was no compelling evidence from either animal or human studies to support cannabinoids for alleviating tinnitus. You can read the review on PubMed.

That is quite different from the message given by many commercial CBD websites.

Claims such as “CBD reduces ringing”, “CBD protects auditory nerves” or “CBD helps the brain filter tinnitus out” go beyond what the evidence currently supports.

Why are researchers interested in cannabinoids and hearing?

The endocannabinoid system is involved in signalling throughout the body, and cannabinoid receptors have also been investigated within auditory pathways.

That provides a scientific reason for researchers to study cannabinoids and tinnitus. It does not mean that activating those pathways will necessarily improve tinnitus.

In fact, some of the experimental results have gone in the opposite direction.

This is a useful example of why a biological mechanism should not automatically be turned into a health claim.

What did the animal research find?

One frequently cited experiment investigated a combination of THC and CBD in rats exposed to acoustic trauma.

Among animals already showing tinnitus-like behaviour after hearing damage, cannabinoid treatment increased the number displaying tinnitus-like responses. The researchers suggested cannabinoids might potentially promote tinnitus under those experimental circumstances. The study is available on PubMed.

There are several important limitations.

This was an animal experiment, not a human clinical trial. The treatment contained THC as well as CBD. The animals had experimentally induced hearing damage. And behavioural measurements in rats are not equivalent to a person describing tinnitus.

Therefore, this study does not demonstrate that CBD causes tinnitus in people.

But it does give us another reason not to claim that CBD has been proven to protect the auditory system or relieve ringing in the ears.

What does human research show?

Human evidence is much less direct.

A 2023 study examined cannabis use and tinnitus in a large sample of US adults. Tinnitus was more prevalent among people reporting cannabis use, and higher-volume cannabis use remained associated with tinnitus after researchers adjusted for a number of other factors. The study can be read on PubMed.

But this was an observational study.

It cannot establish that cannabis caused tinnitus, and importantly cannabis use is not the same as taking CBD isolate. Cannabis contains numerous compounds and may include substantial THC.

We should therefore neither use this research to claim that CBD causes tinnitus nor ignore it and claim that CBD treats tinnitus.

The appropriate conclusion is that the human evidence does not currently provide a sound basis for recommending CBD for tinnitus.

Has CBD itself been clinically proven for tinnitus?

The cannabinoid literature review found that clinical evidence was largely lacking and concluded there was no compelling evidence supporting cannabinoids for tinnitus.

In our current 2026 evidence check, we also did not find a randomised human clinical trial demonstrating that oral CBD itself treats tinnitus.

There are modern randomised tinnitus trials investigating approaches such as hearing interventions, psychological therapy and digital tinnitus programmes — but that is not evidence for CBD.

So if someone asks:

“Has CBD been clinically proven to stop tinnitus?”

The answer is currently:

No.

What about using CBD for the stress or sleep problems associated with tinnitus?

This needs particular care.

Tinnitus can certainly affect sleep and emotional wellbeing, and NICE specifically recognises the psychological impact tinnitus can have.

However, that does not allow a CBD retailer to say its oil treats the anxiety, stress or sleep problems associated with tinnitus.

The Food Standards Agency states that CBD foods are not medicines and that there are no authorised health claims for CBD food products. It also states that claims that CBD foods relieve pain, improve sleep or treat illness are not permitted.

For current UK guidance, see the Food Standards Agency guidance on CBD safety and health claims.

The MHRA also states that CBD products marketed for medical purposes, or using medicinal claims, can fall within medicines regulation. See the MHRA statement on products containing CBD.

That is why we should not suggest that high-strength CBD helps people sleep despite tinnitus or helps manage tinnitus-related anxiety.

Could CBD make tinnitus worse?

There is not enough human evidence to say that CBD itself worsens tinnitus.

Some animal cannabinoid research has raised concerns, and observational human research has found associations between cannabis use and tinnitus. But neither provides proof that purified CBD causes tinnitus in people.

So the balanced answer is:

We do not currently have strong evidence that CBD improves tinnitus, but neither do we have good evidence demonstrating that CBD isolate causes it. More targeted human research is needed.

What does UK guidance recommend for tinnitus?

UK clinical guidance focuses on assessing tinnitus properly and addressing its impact rather than recommending CBD or other unproven supplements.

NICE recommends audiological assessment for people with tinnitus. Where hearing loss is also present, hearing aids or other amplification devices may be appropriate depending on the person's circumstances.

For adults whose tinnitus continues to cause emotional, social or day-to-day difficulties, NICE recommends a stepped approach to tinnitus-related psychological therapy. This can include digital tinnitus-focused cognitive behavioural therapy (CBT), group interventions and individual CBT.

You can read the current NICE tinnitus recommendations.

These recommendations are based on clinical tinnitus management rather than CBD marketing.

When should tinnitus be checked by a healthcare professional?

The NHS recommends speaking to a GP if tinnitus occurs regularly or constantly, is worsening, or is affecting areas such as sleep, concentration or emotional wellbeing.

Tinnitus that beats in time with your pulse requires urgent GP assessment.

The NHS advises going to A&E or calling 999 if tinnitus occurs after a head injury or alongside sudden hearing loss, facial weakness or a spinning sensation such as vertigo.

For the latest public guidance, see the NHS tinnitus page.

Those symptoms should not be self-managed with CBD or another supplement.

Current UK CBD safety guidance

There is another important distinction between clinical CBD research and ordinary CBD foods.

The FSA currently advises healthy adults not to consume more than 10mg CBD per day from CBD foods.

People taking medication are among the groups the FSA advises to avoid CBD unless under medical direction because of uncertainty around safety and potential medication interactions.

This is especially relevant to an article about a health condition: someone looking for tinnitus information may also be taking prescription medicines.

We should never convert doses appearing in cannabinoid studies into Valley CBD dosing instructions.

Frequently asked questions

Does CBD stop ringing in the ears?

There is currently no good human evidence demonstrating that CBD stops tinnitus. Existing cannabinoid research does not provide a basis for claiming that CBD is a tinnitus treatment.

Can CBD make tinnitus worse?

There is insufficient human research to conclude that purified CBD either improves or worsens tinnitus. Some animal cannabinoid research has reported increased tinnitus-like behaviour, but those findings cannot simply be applied to humans or to CBD isolate.

Is cannabis the same as CBD?

No. Cannabis can contain numerous cannabinoids and other compounds, including THC. Research concerning cannabis or THC should therefore not automatically be treated as research about purified CBD.

Has CBD been clinically tested as a tinnitus treatment?

Current evidence does not establish CBD as an effective tinnitus treatment. The published cannabinoid literature has described human clinical evidence as very limited.

Can I take CBD if I use medication?

The FSA advises people taking medication to avoid CBD unless under medical direction because CBD can interact with some medicines.

What treatments are recommended for tinnitus?

Treatment depends on the individual and any underlying hearing problems. NICE recommends audiological assessment and may recommend hearing devices where hearing loss is present. For tinnitus-related distress, tinnitus-focused psychological approaches including CBT can be considered.

The bottom line

There is scientific interest in cannabinoids and auditory signalling, but interest is not the same as proof of benefit.

Existing animal research has produced mixed and sometimes concerning findings, while human evidence does not demonstrate that CBD treats tinnitus. Cannabis observational research should also not be confused with research on purified CBD isolate.

We can explain the research, including its limitations, but we should not claim that Valley CBD oils reduce tinnitus, improve tinnitus-related sleep or anxiety, protect auditory nerves or provide a treatment for ringing in the ears.

That is both more scientifically accurate and more consistent with current FSA and MHRA guidance.
