The Science of Edibles and Red Eyes

Edibles have become a popular way for many people to consume cannabis and experience its effects in a discrete manner. But what exactly are edibles and why do they sometimes lead to those telltale red eyes? Let’s explore the science behind it all.

What Are Edibles?

Edibles are food products infused with cannabis extracts like THC and CBD. They come in many forms like baked goods, candies, chocolates, beverages, tinctures, and more. The popularity of edibles has skyrocketed in recent years with the legalization of cannabis in many places. Edibles provide a way to receive the benefits of cannabis without smoking.

The most common types of edibles include gummies, chocolates, cookies, brownies, and candies. These are ingested orally and metabolized differently than smoking, resulting in a delayed onset of effects. Tinctures placed under the tongue are another popular edible format for faster absorption.

No matter the type, it’s important to start with a low dose and increase slowly. Edibles take time to kick in, making it easy to consume too much if you’re not patient. Going slow helps ensure an enjoyable experience.

Why Do Edibles Make Your Eyes Red?

Red, bloodshot eyes are a classic sign someone has consumed cannabis. But why does this happen? The answer lies in the body’s endocannabinoid system.

THC and other cannabinoids in cannabis interact with CB1 receptors in the body and brain. Some CB1 receptors are located near the eyes. Activation of these receptors causes vasodilation (widening of blood vessels) in the eyes, allowing more blood to flow in.

The increased blood flow enlarges the vessels and gives the eyes a reddish hue. CBD is also known to widen blood vessels, so edibles with a THC and CBD combination can be especially prone to making eyes red.

Beyond cannabinoids, factors like lack of sleep, allergies, and rubbing your eyes can also induce redness. But in most cases, edibles lead to red eyes due to the abundance of cannabinoids.

So next time you indulge in cannabis edible, be prepared for a high chance of having noticeably red eyes. Stay hydrated and use medicated eye drops to help constrict blood vessels and reduce redness if needed. And enjoy your edible responsibly!

Tips to Reduce Red Eyes from Edibles

There are some simple tips to help prevent or reduce red eyes from edibles:

Stay Hydrated – Dehydration causes blood vessels in the eyes to expand, leading to redness. Be sure to drink plenty of water before, during, and after consuming edibles to stay hydrated. This will help minimize vasodilation in the eyes.

Use Eye Drops – Over-the-counter eye drops containing tetrahydrozoline can quickly constrict blood vessels in the eyes and reduce redness. Apply as needed if you notice your eyes getting red after taking an edible.

Manage Your Dosage – Consuming too large of a dose of edibles at once increases the likelihood of side effects like red eyes. Start with a low dose, especially if you’re new to edibles, and wait at least 2 hours before taking more. This gives time for effects to kick in before overdoing it.

Apply Cool Compresses – Placing a cool, damp washcloth over your closed eyes can soothe redness and irritation. The slight pressure also helps constrict blood vessels. Do this as needed for relief.

Avoid Rubbing Your Eyes – Rubbing your eyes tends to make redness worse by irritating the delicate skin and blood vessels. Try to avoid touching your eyes if they feel irritated after consuming cannabis.

Use Eye Drops Preventatively – If you know your eyes tend to get very red and irritated from edibles, use eye drops preventatively. Apply drops just before or immediately after consuming edibles to preemptively reduce redness.

Staying proactive and using remedies as needed can help minimize red, bloodshot eyes from edibles. Be sure to drink water, manage dosage, and have eye drops on hand. With some simple precautions, red eyes don’t have to be a problem.

How to treat your eyes if your eyes are red from Edibles?

Red eyes from edibles are not a sign of harm or damage, but rather a result of the dilation of the blood vessels in the eyes due to the action of THC, the main psychoactive compound in cannabis. This lowers the intraocular pressure and increases the blood flow to the eyes, making them appear red. Red eyes from edibles are usually temporary and harmless and can be prevented or reduced by using eye drops, drinking water, or choosing low-THC strains of cannabis.

However, some people may have allergic reactions to edibles or other ingredients in them, which can cause more severe symptoms such as itching, swelling, or pain in the eyes. If this happens, it is important to seek medical attention as soon as possible. For more information about red eyes from edibles.

Is it dangerous to get red eyes from Edibles?

No, getting red eyes from consuming edibles is not dangerous or harmful. It can be an annoyance, but it does not pose any threat to your vision or eye health.

The red, bloodshot eyes are caused by cannabis’ ability to dilate blood vessels. The tiny capillaries in the sclera (the white part of the eyes) expand which makes them more visible and gives the eyes a reddish hue. However, this vasodilation does not damage the eyes.

It’s simply a cosmetic side effect of edibles, similar to how some people’s eyes may get red after drinking alcohol. There are no long-term risks to your eyesight or ocular health from occasional red eyes after taking edibles.

In rare cases, some people may experience dryness, irritation, or burning sensations if their eyes get very red. This is temporary and can be relieved with some eye drops. But overall, red eyes from edibles will clear up on their own within a few hours as the effects of cannabis wear off.

The most important thing is to not panic if you notice red eyes after consuming edibles. Stay hydrated, use eye drops as needed, and avoid rubbing your eyes excessively. The redness will dissipate once the edible is fully metabolized. It’s harmless, despite being visually unattractive during the high.


In conclusion, consuming edibles can indeed cause red eyes due to the dilation of blood vessels. However, it varies from person to person and using eye drops can help alleviate the redness. Remember to consume responsibly and be aware of the potential side effects.


Q: Do edibles make your eyes red?

A: Yes, edibles can make your eyes red, just like smoking cannabis can. This is because edibles contain THC, the psychoactive compound in cannabis that causes the high. THC lowers blood pressure which dilates the blood vessels in the eyes and makes them appear red.

Q: How long do edibles make your eyes red for?

A: The duration of red eyes from edibles depends on several factors such as the dose, the potency, the metabolism, and the hydration of the user. Generally, edibles take longer to kick in and last longer than smoking, so the red eyes may also last longer. A typical range is from 4 to 12 hours.

Q: How can I prevent or reduce red eyes from edibles?

A: There are a few ways to prevent or reduce red eyes from edibles, such as:

  • Choosing edibles with lower THC content or higher CBD content, as CBD can counteract some of the effects of THC.
  • Drinking plenty of water before and after consuming edibles, as dehydration can worsen red eyes.
  • Using eye drops that are designed to lubricate and soothe the eyes, such as artificial tears or antihistamines.
  • Wearing sunglasses or contact lenses that can mask or minimize the redness of the eyes.
