But does the research really back that up? Read on to find out.
Tinnitus is when people hear ringing or other noises in their ears that aren’t caused by an external source. It’s more common in older adults, but it can happen to anyone.
While tinnitus varies in severity, for some, the constant buzzing, roaring, or ringing can cause extreme distress.
Tinnitus is considered a symptom and not a condition in and of itself. Potential causes include:
- age-related hearing loss
- regular exposure to loud sounds
- high blood pressure
- high cholesterol
- middle ear muscle spasms
- having too much ear wax
- middle or inner ear damage
- medications, including nonsteroidal anti-inflammatory drugs (NSAIDs), some antibiotics, cancer medications, and diuretics
- head and neck injuries
- temporomandibular joint disorders
- Meniere’s disease
- ear or auditory nerve tumors
Treatment for tinnitus usually involves treating the underlying cause.
Your doctor might recommend removing excess earwax and stopping medications that might be causing your tinnitus. Some drugs, like tricyclic antidepressants, may help dampen ear sounds.
Unfortunately, it can sometimes be tough to pinpoint the cause for ringing in the ears. If your doctor can’t find a reason for your tinnitus, or if the treatments for the underlying cause don’t work, you may need to manage your tinnitus by blocking irritating sounds with a white noise machine.
Both full-spectrum and broad-spectrum CBD contain other cannabinoids, flavonoids, and terpenes from the cannabis plant. Full-spectrum CBD also contains a small amount of THC (less than 0.3 percent for federally legal products). CBD isolate is pure CBD.
However, it’s important to recognize that any CBD product, no matter the type, can have trace amounts of THC in it and could show up on a drug test.
The two are not the same. Hempseed oil contains only trace amounts of CBD. CBD is mostly found in the stalks, leaves, and flowers of the hemp plant.
Unfortunately, some brands incorrectly label hempseed oil products as containing CBD — sometimes by mistake and sometimes on purpose.
Looking at the ingredient list and certificate of analysis (COA) will let you know exactly what you’re buying. If you want a CBD product, search for terms, like:
- full-spectrum hemp
- hemp oil
We’ve all got an endocannabinoid system (ECS) consisting of endocannabinoid receptors throughout the body. Your body has two main endocannabinoid receptors: CB1 and CB2. It also makes molecules called endocannabinoids which are similar to cannabinoids found in the cannabis plant.
Why does your body make them? Experts don’t quite know everything there is to know yet about the ECS. But it likely helps keep your internal systems working smoothly.
When endocannabinoids bind to either CB1 or CB2 receptors, this produces effects depending on the location of the receptors. For example, endocannabinoids produced by your body might bind to immune cell receptors to let your body know it’s experiencing inflammation.
When endocannabinoids have done their job, enzymes break them down.
Again, experts don’t really know the exact mechanisms behind how CBD interacts with the ECS. Still, they’re aware that CBD binds differently to CB1 and CB2 receptors compared with THC — possibly by preventing the breakdown of endocannabinoids.
Experts also suspect that CBD produces more noticeable effects when paired with THC. That’s why full-spectrum and broad-spectrum products are more likely to provide benefits than ones containing CBD isolate. This is known as the entourage effect.
Research on CBD for tinnitus is mixed.
A 2015 animal study suggested that a combination of CBD and THC may actually make tinnitus worse.

Potential side effects include:
- weight loss or gain
While you’ll probably only ever experience mild side effects, it’s essential to talk with a doctor before trying CBD, especially if you’re taking any medications. CBD may interact with some medications.
Additionally, it’s important to know that the
You’ll have to do your own research to make sure you’re buying a high quality product.
There’s no evidence that CBD can help with tinnitus, but if you want to try it, we recommend opting for an oil due to its higher bioavailability and ability to produce full-body effects.
There are a lot of not-so-great CBD products on the market. Here’s how to figure out if a CBD product is high quality:
- Look for third-party testing. A quality product should come with a COA that you can read before buying. It should confirm that what’s on the label is accurate, as far as CBD and THC content. It will also tell you whether the product has passed tests for contaminants.
- Scan ingredients lists. CBD products should contain hemp, hemp extract, or hemp oil. Hempseed oil products only contain trace amounts of CBD. Ideally, opt for a product that contains organic ingredients.
- Confirm the cannabis source. Make sure the brand you’re buying from is transparent about where it grows its hemp and what the manufacturing processes are.
- Read reviews. Look through customer reviews to see what other people have to say. And steer clear of Amazon. Amazon prohibits the sale of CBD, so any “CBD” products on there are probably actually hempseed oil products.
While research suggests that CBD has promising qualities, like alleviating pain and helping with anxiety, there’s no scientific evidence that CBD or any other cannabis product can help with tinnitus.
That said, CBD may help you deal with the side effects of constant ringing in your ears, like sleep troubles and stress. Be sure to talk with your doctor before trying CBD.
Is CBD Legal? Hemp-derived CBD products (with less than 0.3 percent THC) are legal on the federal level, but are still illegal under some state laws. Marijuana-derived CBD products are illegal on the federal level, but are legal under some state laws. Check your state’s laws and those of anywhere you travel. Keep in mind that nonprescription CBD products are not FDA-approved, and may be inaccurately labeled.
