Red eyes are the telltale sign of a stoner. Does smoking CBD cause the same easily recognizable effect? Find out if CBD makes your eyes red in this guide. Smoking a joint or two can definitely cause the tell-tale red eyes. But does CBD also cause red eyes, and if so, how can you avoid it? We'll tell you! Discover whether CBD will make your eyes red or if THC found in cannabis is the true cause of red, bloodshot eyes and how to treat red eyes.
Does CBD Make Your Eyes Red?
THC use has become a lot more prevalent over the last few years. That doesn’t necessarily mean, however, you want to be identified as a stoner just because you use CBD.
Even though having red eyes isn’t dangerous, it’s understandable that you’d like to know whether smoking or vaping CBD is likely to make your eyes red. Find out whether CBD will make your eyes red, and discover some of the key differences between smoking THC and smoking CBD.
Why do some cannabis products make your eyes red?
Since the dawn of stoner culture, having red eyes has been considered a telltale sign that you’ve recently partaken of reefer. Even though the average cannabis smoker has no idea why weed makes your eyes red, their bloodshot, swollen eyeballs have either been exhibited as objects of pride or desperately hidden from law enforcement officers.
Why does Cannabis sativa make your eyes red, though? Many cannabis smokers would guess that weed smoke gets in your eyes and makes them irritated. If that’s the case, however, why don’t cigarettes or campfires do the same thing?
To find the answer, we need to turn back time to the early days of the medical cannabis movement in the United States. American culture was far more averse to cannabis then than it is now, but voters and legislators were still swayed by the evidence that medical weed could help with serious conditions.
The role of glaucoma in medical cannabis
The first medical cannabis patients in California and other early-adopter states sought help with chemotherapy-induced nausea and terminal illnesses. In some cases, they also used medical cannabis for glaucoma , an ocular condition that causes swelling in the eyeballs.
Somewhat ironically, glaucoma can make your eyes red. There’s nothing funny, though, about the damage this condition dealsa to your optic nerves over time, potentially leading to blindness.
At the root of glaucoma is increased intraocular pressure, which is in turn caused by ocular hypertension. Wherever it occurs in your body, high blood pressure can wreak havoc and lead to severe medical conditions, and in the case of glaucoma, hypertension can take away your sight.
Early advocates of medical cannabis treatment for glaucoma didn’t recommend weed because it gets you high, allowing a brief blissful respite from sober awareness of your swollen eyeballs and deteriorating optic nerves. On the contrary, they suggested that cannabis might have vasodilatory properties .
Because THC makes your veins expand, it can reduce intraocular pressure and help with glaucoma. By widening the capillaries in your eyes, however, marijuana also allows blood to flood into your peepers, making your red ocular capillaries stand out more than usual.
So no, your eyes don’t get red after you smoke weed because you got smoke in your eyes or you have the munchies. It’s for the same reason that cannabis helps with glaucoma — THC is a vasodilator that increases blood flow throughout your body.
Does CBD make your eyes red like THC?
If THC makes your eyes red because it is a vasodilator, does CBD do the same thing? To answer this question, let’s take a look at research into the cardiovascular effects of CBD and note the anecdotal evidence on subject.
Quite a few CBD users have noted eye redness after smoking CBD or ingesting this cannabinoid in another way. In some cases, these symptoms can be attributed to ingesting CBD products that also contain THC.
Certain red-eyed CBD users insist, however, that they ingested CBD product types that only contain cannabidiol without THC.
The available evidence on CBD and intraocular blood pressure seems to conflict with this anecdotal testimony. While clinical research has been conducted into the potential vasodilatory effects of CBD , research indicates that this cannabinoid might increase intraocular blood pressure , not lower it.
So far, the evidence on CBD and intraocular pressure is too limited to reach any firm conclusions. Based on what we do know, however, it’s extremely unlikely that smoking CBD or ingesting this cannabinoid another way will make your eyes red.
Lots of things aside from CBD can make your eyes red, however. Allergies, illnesses, and other factors can irritate your eyes, and vasodilators aside from THC can also increase ocular blood flow.
These alternative factors might help explain cases in which people who used CBD experienced eye reddening despite the fact that this cannabinoid does not share the vasodilatory properties of THC.
Other differences between smoking CBD and THC
The eye redness associated with THC certainly occurs in tandem with this cannabinoid’s intoxicating effects. THC doesn’t make your eyes red because it gets you high, though.
If you want to avoid getting high and keep your eyes from getting red at the same time, you might want to try smoking CBD instead of THC. Unlike THC, CBD won’t get you high no matter how much CBD-rich hemp flower you smoke.
This means that smoking CBD also doesn’t cause anxiety or any other common side effects of THC. Existing research hasn’t found that CBD has any habit-forming properties, and it doesn’t even appear to give you the munchies.
In general, smoking CBD is a much more relaxing and mild experience than smoking THC. While THC provides you with an initial rush of euphoria, this sense of intoxication undeniably alters your mental state.
Smoking CBD, on the other hand, offers all the delicious aromas and flavors of Cannabis sativa without getting you high. Even better, CBD doesn’t appear to have any serious side effects , so you can enjoy this cannabinoid without worrying about damaging your health.
As if all these advantages weren’t enough, you’ve learned in this guide that CBD also won’t give you red eyes. Smoke CBD flower content in the knowledge that you won’t feel high and no one will accuse you of smoking weed based on the color of your eyes.
Will smoking CBD make your eyes red?
Your eyes might become red after using CBD even though this cannabinoid isn’t a vasodilator. By law, CBD flower can only contain negligible THC concentrations, but even that might be enough to cause ocular vasodilation in some people.
It’s also possible to be allergic to specific terpenes, flavonoids, or other compounds in hemp flower. In the end, you might just be the kind of person whose eyes are sensitive to smoke.
There doesn’t appear to be anything in this type of hemp product that will increase ocular blood flow. Still, we won’t 100% guarantee that CBD flower won’t give you red eyes.
THC is such a potent ocular vasodilator that it’s used for glaucoma to this day, but CBD doesn’t share these qualities. If you have any lingering questions about CBD making your eyes red, contact us , and check out our other guides in the Shared Secrets blog .
CBD eye redness FAQ
Still concerned about CBD making your eyes low? Check out these quick answers to popular CBD ocular questions:
1. Does CBD affect your eyes?
It’s possible that CBD might worsen existing cases of glaucoma . This potential side effect intriguingly delineates the differences between CBD and THC — while the medical cannabis movement was largely founded around the utility of THC for glaucoma, CBD might actually be counterproductive to glaucoma treatment.
It’s worth remembering, however, that only one study has shown CBD might lead to an increase in intraocular pressure in patients who already have glaucoma. These results haven’t been corroborated by followup research.
2. Is CBD good for cataracts?
There’s no scientific evidence that CBD might help with cataracts. The development of cataracts appears to be related to oxidative stress , and the impact of CBD on oxidative stress and inflammation has been well-researched . It’s unclear if CBD helps with the same types of oxidative stress involved in cataracts, however.
3. What are the side effects of CBD?
We’re still learning about how CBD affects the body. At present, no serious side effects of CBD have been identified, but this CBD might make you sleepy or experience digestive discomfort.
CBD can also interact negatively with certain prescription medications. Consider consulting with your doctor before trying CBD if you’re concerned about drug interactions.
Do CBD Edibles Make Your Eyes Red?
Stereotypes indicate that red or bloodshot eyes are a tell-tale sign of a well-smoked blunt. However, while this is a generalisation at best, it’s rooted in truth. Marijuana can, in fact, cause red eyes – but can CBD do the same?
Studies indicate that THC could be the reason for red eyes. At CBD Village, however, we consider ourselves industry experts. Therefore, today, we’ll explore the idea of CBD – and whether it can cause red, bloodshot eyes.
Can My CBD Edibles Cause Red Eyes?
Here, the short answer is no – CBD edibles cannot cause bloodshot eyes. This means that you can safely consume your CBD gummies or capsules without fear of those bloodshot eyes.
However, it’s also important to remember that CBD can sometimes cause dry eyes. While this is a fairly rare side-effect, it could affect you – especially if your eyes are rather sensitive. In this case, you might be inclined to rub at your eyes, causing them to turn bloodshot.
Here, you should note that these bloodshot eyes occur due to physical irritation and broken blood vessels. These red eyes aren’t caused by CBD at all. In this case, what causes red eyes?
THC – The Real Culprit
Studies show that THC could be behind those bloodshot eyes. Apparently, marijuana consumption can lower your blood pressure. This, in turn, can dilate and widen the blood vessels in your eyes.
Wider blood vessels mean increased blood flow to your eyes. Therefore, this is what causes red eyes – that complete and total giveaway.
While you might think that smoking a joint or two can cause red eyes, they certainly aren’t the only culprits. In fact, consuming THC in any way, shape, or form can cause this to occur. Due to this, we can conclude that it’s THC – not CBD – behind those red eyes.
Help; I Only Consume CBD, but I Still Have Red Eyes!
Sometimes, you may experience red or bloodshot eyes after consuming CBD. Here, we should reiterate – on its own, CBD cannot cause red eyes. However, there could be a few other factors that cause red eyes.
Smoking and Vaping Can Cause Bloodshot Eyes
First, red eyes could be due to your method of ingestion. For example, smoke and vapour could contribute to bloodshot eyes. Therefore, when you smoke CBD flower, or use CBD e-liquid in your vape pen, this could contribute to red, watery eyes.
In addition to this, sensitive eyes could also play a factor here. When your eyes are sensitive, they could be more susceptible to external factors – including smoke and vapour. A smoky environment could cause red, watery eyes.
In this case, we’d recommend smoking your CBD flower, or puffing on your vape pen in a well-ventilated area. This will draw the smoke or vapour away from your eyes, helping you avoid bloodshot, watery eyes. Additionally, you could also change your consumption method.
Instead of smoking CBD flower, or utilising your vape pen, consider taking an alternative. For example, a CBD oil or tincture could go a long way, in terms of bioavailability. Plus, with this method, you’ll be able to avoid red eyes!
Your CBD Edible Could Contain THC
You might think that you’re consuming a THC-free CBD edible – so why are your eyes still red? Well, it could all come down to your product of choice. In the UK and Ireland, the CBD industry is still largely unregulated.
While the government is trying to implement proper guidelines around CBD products, it can be hard to keep track of them all. Plus, with multiple new businesses popping up every month, the CBD boom is well underway. However, this also means that you might be consuming an unregulated CBD product.
If your product of choice isn’t tested at a third-party lab, then it could still contain THC. With the number of unregulated CBD products on the market, this is becoming a fairly common situation. Earlier, we mentioned that THC – in any form – can cause red eyes.
Therefore, your CBD tincture, or gummies of choice, could contain large amounts of THC. This, in turn, could lead to red or bloodshot eyes. Thankfully, there are ways to avoid this.
First, we’d recommend buying your CBD edibles from a reputable retailer. This will help avoid unregulated CBD products, which could result in red eyes.
Before making a purchase, look for a company with its Novel Foods certifications in order. This will help establish that you’re buying and consuming a government-approved, established CBD product. Generally, these products will only contain trace amounts of THC – perfect for avoiding bloodshot eyes!
We’d also recommend purchasing third-party lab-tested products. These products usually come with Certificates of Analysis (COAs). By browsing these certificates, you’ll be able to tell just how much CBD they contain – and whether or not they contain THC.
With this method, you’ll be able to confirm that you’re buying and consuming THC-free CBD products, effectively dodging watery, red eyes!
So, CBD Doesn’t Cause Red Eyes… but Are There Any Other Side Effects?
By now, we’ve established that CBD isn’t to blame for red eyes. However, it could have some other side effects. While side effects from CBD consumption are fairly rare – especially when you buy from a reputable business, they can still occur.
Here are two of the most common:
- Feelings of exhaustion: Many people take CBD as a sleep aid. While we need more studies to properly conclude its effectiveness, it can sometimes cause feelings of sleepiness and exhaustion. If you experience this with your regular CBD dose, consider changing your consumption method. You can also take a CBD dose just before bedtime!
- Appetite changes: CBD could also play a role in feelings of hunger. Some people report that it increases their appetite, while others say that it suppresses it. If CBD increases your appetite, why not take a dose just before mealtimes? You could also have a selection of healthy snacks on hand – fruit, yoghurt, and protein bars all make tasty treats. However, if CBD decreases your appetite, take your dose right after mealtime, which will help ensure that you don’t skip meals.
In addition to these side effects, CBD could also interact with some medication. To safely consume CBD, discuss its use with your doctor, highlighting any other forms of medication you already take. Once your doctor gives you the green light, you’re good to go!
The Final Word on CBD and Red Eyes
On its own, a CBD edible won’t cause red eyes. However, there are some circumstances where CBD consumption can lead to bloodshot, watery eyes. For example, you might be accidentally consuming THC with your CBD. Your CBD smoke or vapour could also be affecting your eyes.
To avoid accidentally consuming THC, we’d recommend purchasing your CBD edibles from a reputable supplier. Certain online shops – like us, at CBD Village – work to procure and stock the best CBD products on the market. By doing this, we ensure that our customers only get the best CBD options – third-party tested and ready to ship.
As for avoiding smoke and vapour, we’ve got hundreds of other options. Choose from tinctures and teas to creams and capsules – at CBD Village, the choice is yours. Browse our CBD selection right here on the website, and maybe even pick up a new CBD product or two!
Does CBD Make Your Eyes Red? – Stop Worrying About Bloodshot Eyes!
Most people are familiar with the red, bloodshot eyes caused by marijuana. However, many of you also wonder, does CBD make your eyes red?
The good news is that you can stop worrying about whether consuming CBD or cannabidiol results in bloodshot eyes. The cannabinoid is highly unlikely to cause reddening of the eyes.
Why Does Cannabis Cause Bloodshot Eyes?
You have probably watched the iconic Cheech & Chong movies where red eyes are a hallmark sign of smoking cannabis, and you might wonder how much of it is true.
So, does CBD make your eyes red? This is something that a lot of people want to know, especially those outside of the cannabis-using community looking to try out CBD.
CBD is one of many cannabinoids found in the cannabis plant. It does not cause red eyes.
THC or tetrahydrocannabinol is the cannabinoid responsible for causing red eyes among cannabis users. When consumed, THC binds with the body’s endocannabinoid receptors to cause various effects such as euphoria, increased heart rate, dry mouth, memory loss, and red eyes.
THC lowers the body’s blood pressure, diluting the blood vessels in the eyes and leading to redness.
How Does CBD Affect the Body?
Just like THC, CBD also binds with the body’s endocannabinoid receptors, but in a much different fashion. CBD creates a more beneficial and soothing balance without causing any of the cognitive disruptions or unpleasant side effects (such as red eyes) of THC.
Does CBD Cause Red Eyes? It’s a Big ‘No’!
Many users buy CBD gummies online and enjoy the experience, but they also fear getting bloodshot, red eyes. If the question ‘does CBD make your eyes red?’ is swirling in your head, you’ll be happy to know that you can breathe a sigh of relief. You will experience no bloodshot eyes when using any kind of CBD products.
Interestingly, CBD might actually counter reddening of the eyes. Redness is often caused by dryness when the meibomian gland, located behind the eyelids, fails to produce sufficient oils. The lack of the fatty substance causes the water in the eyes to evaporate. The subsequent dryness turns the eyes red..
Research has shown that CBD topicals can actually improve the meibomian gland’s oil production to reduce dryness in the eyes.
How to Reduce Red Eyes After Cannabis Use
It is true that smoking cannabis causes red eyes in many users. Although bloodshot eyes do not usually hurt, many people don’t want to walk around with the discoloration.
Here are four ways to reduce red eyes after cannabis use:
- Consume a vasoconstrictor such as coffee or chocolate to help constrict the eyes’ blood vessels and reduce redness.
- Use over-the-counter moisturizing eye drops to ease dryness and relieve inflammation.
- Wait for some hours for the redness to go away.
- Avoid going out in the sun, which can lead to a deepening of the redness and an increase in irritation.
Treatment for Short-Term Red Eyes
Sometimes you just get red eyes even if you don’t use a THC-laden cannabis product. If you have red eyes after using CBD, then you’ll need to look elsewhere for the cause of the red eyes, such as lack of sleep, dry eyes, eye infection, or excessive drinking or smoking.
Once you pinpoint the cause of the red eyes, you can focus on treatment. Here are four common scenarios:
- Dry eyes: If your eyes are simply dry, then an over-the-counter eye drop will usually bring much-needed relief.
- Eye infection: If you have an infection, such as conjunctivitis, you’ll need to consult a physician to obtain medication to treat it.
- Lack of sleep: If you have simply been burning the candle at both ends too much, then getting some much-needed shuteye will typically ease your red eyes.
- Smoking or alcohol use: Avoid using nicotine products and excessive alcohol consumption.
Treatment for Long-Term Red Eyes
Some medical conditions can lead to long-term red eyes, such as thyroid disorders. Also, eye strain, allergies, contact lenses, and naturally dry eyes can redden your eyes over long stretches of time.
To treat long-term red eyes, you’ll need to meet with your physician to discuss the underlying causes. If you have a thyroid disorder, then restoring hormonal balance can solve the problem.
If you are frequently undergoing eye strain, then you might want to schedule an appointment with an optometrist to obtain prescription eyewear or contacts.
Determining the cause of your allergies can give you a clue on how to prevent allergic red eyes. Using Benadryl or some other allergy medicine can help eliminate the redness.
