Do Edibles Make Your Eyes Red? Yes, Here’s Why

Are you one of those people who have ever indulged in cannabis edibles and ended up with red eyes, wondering why it happens? You are not alone. It can be frustrating when you enjoy the benefits of edibles, but the side effects are making you self-conscious or even worried about your health.

In short, yes, edibles can make your eyes red. This is due to the active ingredient in cannabis known as tetrahydrocannabinol (THC). THC causes blood vessels in the eyes to dilate, leading to increased blood flow and a reddening of the eyes.

Within this article, we will explore the reasons why edibles can make your eyes red and provide some tips on how to prevent and treat it.

Does Consuming Edibles Make Your Eyes Red?

Yes, consuming edibles can make your eyes red.

Is It Normal?

Yes, it’s completely normal for your eyes to turn red after consuming edibles.

How Does It Work?

When you consume edibles containing THC, it is absorbed through your digestive system and then metabolized by your liver, where it is converted into a more potent form of THC called 11-hydroxy-THC. This compound then travels through your bloodstream and eventually reaches your brain, where it produces its psychoactive effects.

One of the effects of THC is that it causes blood vessels to dilate, including those in the eyes. This dilation leads to increased blood flow to the eyes, which in turn causes them to appear red. The exact mechanism behind this process is not fully understood, but it is believed to be related to the way THC interacts with the body’s endocannabinoid system.

How Long Does It Last?

The redness in your eyes typically lasts for several hours after consuming edibles. The exact duration can vary based on factors such as the dosage of THC consumed, your body weight, and your tolerance to cannabis.

Are There Medical Concerns About Having Red Eyes Caused By Eating Edibles?

Yes, there can be medical concerns associated with having red eyes caused by eating edibles. While red eyes are generally considered a harmless side effect of consuming cannabis, they can also be a symptom of a more serious underlying condition. For example, red eyes can be a sign of glaucoma, a group of eye conditions that damage the optic nerve and can lead to blindness if left untreated.

If you have persistent redness in your eyes or other eye-related symptoms after consuming edibles such as gummies, it’s important to monitor your eye health and seek medical attention if necessary.

Are There Benefits?

There may be potential benefits associated with consuming edibles and their effects on eye health. Studies suggest that cannabinoids like THC and CBD may have neuroprotective and antioxidant properties that could potentially benefit eye health and be used to treat conditions like glaucoma. THC in particular has been shown to effectively lower intraocular pressure in the eyes, which can help relieve symptoms of glaucoma.

How to Treat Red Eyes After Consuming Cannabis

If you experience red eyes after consuming cannabis, there are several ways to treat it.

Use Eye Drops

One of the easiest and most effective ways is to use eye drops specifically designed to reduce redness.

These drops work by constricting the blood vessels in the eye, reducing inflammation and redness. However, it’s important to choose eye drops that are safe to use with cannabis and avoid products that contain harmful preservatives or other chemicals.

Cool Compress 

This method can help to constrict the blood vessels and reduce inflammation. Simply wet a clean cloth with cool water and place it over your eyes for several minutes.

And if your red eyes are accompanied by other symptoms such as headache, nausea, or dizziness, it’s important to seek medical attention immediately. These symptoms could indicate a more serious underlying condition and should not be ignored.

Tips to Prevent Having Red Eyes

While red eyes are a common side effect of consuming cannabis, there are several steps you can take to prevent or reduce their occurrence:

  • Choose strains with lower THC content: THC is the primary psychoactive compound in cannabis and is responsible for many of its effects, including red eyes. By choosing strains with lower THC content, you may be less likely to experience redness in your eyes.
  • Use eye drops before consuming: If you know that red eyes are a common side effect for you, consider using eye drops before consuming cannabis to help prevent redness from occurring.
  • Stay hydrated: Dehydration can exacerbate the effects of cannabis, including red eyes. Be sure to drink plenty of water before and after consuming to stay hydrated.
  • Avoid rubbing your eyes: Rubbing your eyes can irritate them and make redness worse. If you experience itching or discomfort, use eye drops or a cool compress instead.

Can CBD edibles causes your eyes to go red?

Yes, CBD edibles can cause red eyes in some individuals. Although CBD is non-psychoactive and does not produce the same intoxicating effects as THC, it can still affect blood flow and circulation, which can cause blood vessels in the eyes to dilate and result in redness.

Can edibles affect vision or other aspects of eye health?

While red eyes caused by edibles may be a temporary side effect, there is no evidence to suggest that consuming cannabis edibles can have long-term effects on vision or other aspects of eye health.

Can you also get red eyes from smoking weed?

Yes, smoking cannabis can also cause red eyes for the same reason that edibles do – THC causes blood vessels in the eyes to dilate, leading to increased blood flow and a reddening of the eyes.
