Does CBD Make Your Eyes Red?

Published: Updated:

As the use of CBD becomes increasingly widespread, questions about its side effects continue to surface. One of the most frequently asked questions is: "Does CBD make your eyes red?" Often associated with the use of cannabis, red eyes are actually a common side effect of THC, not CBD. However, the difference between these two compounds and their effects can be confusing for many. In this blog, we aim to clarify these differences and address your concerns, offering an in-depth exploration of whether CBD usage can lead to red eyes, what causes this reaction, and how it can be managed or prevented.


What causes red eyes after using cannabis products?

The primary cause of red eyes after using cannabis products is due to the substance's ability to lower blood pressure and dilate blood vessels, increasing blood flow. When smoked or ingested, cannabis, specifically THC, the psychoactive compound in the cannabis plant, dilates the small blood vessels in the eyes. This action causes increased blood flow and a decrease in intraocular pressure, leading to red eyes. It's worth noting that not all cannabis users will experience this, as individual reactions may vary.

Does CBD make your eyes red like THC does?

Unlike THC, CBD, or cannabidiol, another compound found in the cannabis plant, does not typically cause red eyes. The question is common, as many associate cannabis use with this symptom. However, while both CBD and THC are cannabinoids, they affect the body differently. CBD does not have the same vasodilating effects as THC and, thus, is less likely to cause red eyes, even when used in products like CBD oil.

What are the differences between CBD and THC in relation to eye redness?

The key difference between CBD and THC concerning eye redness lies in their distinct interactions with the endocannabinoid system in the body. THC binds to the CB1 receptors, which are abundant in the eyes, and in doing so, dilates blood vessels and increases blood flow, leading to red eyes. CBD, on the other hand, has a different mechanism of interaction with the endocannabinoid system. Unlike THC, CBD's influence doesn't lead to red eyes, despite both being compounds from the same cannabis plant.

How can I prevent red eyes after using cannabis products?

While CBD products are not typically associated with causing red eyes, some users who are particularly sensitive may experience this side effect. If you're using a CBD product with a small amount of THC, you may also experience red eyes due to the THC content. If you're concerned about red eyes after using cannabis products, there are a few strategies you can employ. Hydrating before and after using cannabis can help, as can using over-the-counter eye drops. You might also consider seeking out products with a lower THC content or a higher ratio of CBD to THC.

Are there long-term effects of CBD use on eye health?

As of now, there is no substantial evidence suggesting that long-term use of CBD negatively affects eye health. It's important to note that much of the research on CBD is still in its early stages, and more studies are needed to conclusively understand all of CBD's potential effects. However, the current consensus is that CBD does not cause any significant eye health problems. Always consult your personal doctor or healthcare provider before starting or changing a cannabis regimen.

Is eye redness a sign of an allergic reaction to CBD?

While it's uncommon, some people may have an allergic reaction to CBD or other components in CBD products. Symptoms of a possible allergic reaction may include red eyes, but it could also include other symptoms like skin rash, itching, shortness of breath, or swelling. If you suspect that you're having an allergic reaction after using CBD, discontinue use immediately and consult a healthcare professional. It could be an allergy to the CBD itself or another ingredient in the product. Always ensure you are buying your CBD products directly from reputable sources to avoid any harmful contaminants.
