Cannabis, especially marijuana, is often associated with red eyes in the collective imagination, especially regarding smoking. Marijuana smokers can often be easily identified by the red rings around their eyes, along with characteristics like drowsiness, euphoria, and sometimes excessive hunger also called the munchies. However, people need to understand that THC, not CBD, causes inflamed, watery, and red eyes. But why is that the case? And will CBD ever make your eyes red or dry? 

Our cannabis and CBD experts at Care Division are here to explore these essential questions to help you better understand the impacts CBD has on your body. Please continue to learn everything you’ll need to know about the issue, and also consider exploring our selection of other educational CBD resources for even more information.

Why Doesn’t CBD Cause Red or Dry Eyes?

You’ll first want to understand that CBD will not turn your eyes red or dry, no matter how much you smoke, consume, or put on your body, because it doesn’t cause the same effects as THC. They are two different cannabinoids that trigger a diverse range of symptoms in those who smoke or consume them, despite being found in the same plant. To better explain the situation, let’s delve into the primary differences between THC vs. CBD


THC is the well-known psychoactive component of cannabis that results in a sensation of being “high” or euphoric, but it also causes other symptoms, including red, irritated eyes. This effect occurs because THC dilates blood vessels and lowers blood pressure while ultimately causing the usually small, unnoticeable blood vessels in the eyes to appear more prominent. The higher blood flow in the eyes then triggers excess redness, watering, and irritation, creating the telltale look associated with marijuana smokers. However, the smoke produced from marijuana pipes or joints may also exacerbate eye redness and irritation.

In contrast, CBD is a nonpsychoactive cannabinoid that will not get users high and instead produce a range of other, often beneficial symptoms. CBD is often used to help people relieve pain, relax, and sleep well without altering their mental states. It also doesn’t cause the same effects on blood vessels as THC or cause blood to rush to the eyes. If someone smokes or consumes CBD or CBD-based products, those around them are not likely to notice, as they likely would when someone smokes or consumes THC.

However, please keep in mind that too much of anything can be bad for you, so be sure you don’t go overboard. Just because it’s harder for others to tell if you’ve been smoking or consuming CBD products compared to THC ones doesn’t mean you should go too far. Consider reading our specialized guide on how much CBD is too much and the effects it can cause to learn more.

Used CBD and Still Got Red, Dry Eyes? You May Have Been Scammed

If you’ve ever smoked CBD or consumed a CBD product that you thought was THC-free and still ended up with red, irritated eyes, then it wasn’t actually THC-free. Throw the product out right away if you genuinely don’t want to deal with those effects or have THC in your system. 

Try using eye drops to relieve the inflammation, and consume things like coffee, chocolate, and salt to help narrow your blood vessels. You’ll generally need to be patient and wait for the issue to resolve itself, but those tactics can sometimes help speed up the process.

You always want to be careful about where you get your products, what brand they belong to, how much they cost, and other critical factors that can help you determine the quality of the product. You’re more likely to encounter this kind of issue if you get your CBD from a friend or an uncertified seller, so always be sure you’re getting your flower and other products from quality, trustworthy sources, like Care Division.

Reducing the Risk of Red Eyes from CBD Oil 

There are a few additional things you can do to reduce your risk of experiencing red eyes from CBD oil: 

Start with a low dose: If you’re new to using CBD oil, it’s important to start with a low dose and increase gradually as needed. This will help your body get used to the compound and reduce the likelihood of side effects. 

Store properly: Store your CBD oil in a cool, dark place away from direct sunlight. This will help preserve the quality of the product and prevent it from causing irritation. 

CBD oil is a popular natural remedy that is generally well tolerated; however, it can cause some side effects, including red eyes. Red eyes from CBD oil are thought to be caused by reduced tear production. You can reduce your risk of experiencing this side effect by starting with a low dose, using a high-quality product and storing properly. If you do experience redness or irritation after using CBD oil, try using artificial tears or over-the-counter eye drops for relief.

Are There Any Other Side Effects of CBD Oil That People Should Be Aware Of?

CBD oil is a popular product that many people use for its potential health benefits. While CBD oil is generally considered safe, it can cause some additional side effects in some people.

Dry mouth: CBD oil can cause dry mouth in some people. This is because CBD oil can affect the production of saliva. Dry mouth can be uncomfortable and can lead to other problems such as bad breath and difficulty swallowing. 

Drowsiness: Another potential side effect of CBD oil is drowsiness. This is because CBD oil can interact with certain medications that are used to treat conditions such as anxiety and insomnia. If you are taking any medications, it is important to talk to your doctor before you start using CBD oil. 

Interactions with other medications: As mentioned above, CBD oil can interact with other medications. It is important to talk to your doctor about all of the medications that you are taking before you start using CBD oil. This is because CBD oil can increase or decrease the levels of certain medications in your blood. 

CBD oil is generally considered safe, but it can cause some side effects in some people. If you are considering using CBD oil, it is important to talk to your doctor first so that you can be sure it is right for you. Additionally, if you do start using CBD oil, be sure to watch for any potential side effects so that you can stop using it if necessary. If you experience any adverse effects after taking CBD oil, stop using it immediately and consult your doctor.
