Is CBD responsible for red eyes? Why does THC cause this effect, and what are the fundamental differences between these two cannabinoids? 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.
Can CBD make your eyes red?
In the collective imagination, cannabis is associated with red eyes and a cerebral high. Marijuana smokers can even be easily identified by their red, ringed eyes, euphoria, and drowsiness. The only problem is that red eyes are a side effect of tetrahydrocannabinol (THC).
Unlike THC, cannabidiol (CBD) does not cause red, inflamed, watery eyes. This side effect usually occurs after consuming a product with a very high THC content.
You’re probably wondering why CBD doesn’t make your eyes red like THC, even though both cannabinoids come from the same plant. Why one and not the other? What is the difference between THC and CBD? Why does THC cause red eyes and what can be done about it? All the answers to your questions about CBD and red eye can be found in this article.
Why is CBD not responsible for red eyes?
Therapeutic cannabis can relieve many pains, alleviate stress and anxiety, and help you get a good night’s sleep. Indeed, it is able to affect mood, appetite, pain, sleep, and many other parameters to regulate your body. But when it comes to red eyes, THC is the only molecule responsible.
This is because THC lowers blood pressure and dilates blood vessels, which causes small blood vessels to appear in the eyes. This high blood flow is manifested by red, irritated and watery eyes. A look often associated with cannabis smokers.
That said, CBD is a cannabinoid that does not act like THC. CBD doesn’t cause that rush of blood to the eyes, so it’s not responsible for red eyes. But the difference between CBD and THC does not end there. To fully understand, it seems essential to know the fundamental differences between these two molecules.
The difference between CBD and THC
Hemp lovers have always consumed THC. This molecule, naturally present in cannabis plants, causes psychoactive effects that are highly appreciated by some people, yet illegal. Without human intervention, cannabis has a THC content that predominates over CBD. In some countries, THC can be used for medical purposes. Although THC is still prohibited in France because of its psychoactive effects, its potential should not be underestimated, nor should we stigmatize consumers who may find it a source of relief.
Over time and genetic crossbreeding, some varieties with high CBD content have emerged. Today, products marketed with CBD do not contain THC. They are therefore completely devoid of psychoactive and euphoric effects. CBD allows you to relax, relieve physical pain and sleep well, without altering your physical and mental state, and without any danger to your health.
How does CBD work on the body?
At first glance, THC and CBD look very similar. But if you take a closer look at them, the way they work and their effects are totally different. One of the biggest differences is the chemical structure of CBD, which contains an extra combination of oxygen and hydrogen. This extra layer allows the multiple benefits of cannabis to be enjoyed without disrupting cognitive abilities.
From scientific research, we know that CBD is intimately linked to the endocannabinoid system. Thus, it regulates the body in a beneficial and non-aggressive way. Among these beneficial effects, we can mention the regulation of sleep and mood, the relief of physical pain and mental tension. The dilation of blood vessels and the appearance of red eyes are not part of the effects of CBD.
Why do THC users have red eyes?
As previously explained, the main reason why THC users get red eyes is because of the dilation of blood vessels, especially the blood flow to the eyes. The higher the level of THC, the greater the effect.
The eyes can also become red from tobacco smoke, which is often very irritating. Smoke that enters the sinuses can also make this problem worse. This explains why smokers of cannabis in joint form have red eyes much more easily.
CBD and red eyes: beware of scams!
You have consumed CBD and you have red eyes? You should ask yourself questions about the origin of the product you bought. If your CBD came from a friend or an uncertified seller, you may have consumed THC without your knowledge. In fact, if you have experienced a cerebral high, a great euphoria and an almost uncontrollable urge to sleep, you can be sure that you have taken cannabis with THC.
Normally, all CBD products that you can find on the internet or in a physical shop are subject to numerous quality controls and must meet very strict European standards. By going through a reputable and certified seller, you are guaranteed to get a product rich in CBD and totally free of THC. To conclude, always be vigilant about the origin of the products you consume to avoid unpleasant surprises.
How to get rid of red eyes?
However, if you have been consuming THC or using CBD with tobacco, you probably want to get rid of those unsightly and slightly painful red eyes. To relieve the inflammation and get back to healthy eyes, here are some tips:
- Use eye drops: Putting a few eye drops in your eyes will quickly and effectively relieve the inflammation, while reducing the red, irritated appearance.
- Consume vasoconstrictors: Certain foods such as chocolate, coffee, and salt help counteract the dilation of blood vessels by narrowing them.
- Be patient: Red eyes never stay red for long. Sometimes all it takes is a little rest to make red eyes go away. In the meantime, avoid exposure to screens and sunlight for a few hours, as this may make the condition worse.
Are red eyes bad for my health?
Red eyes are unsightly and sometimes painful, but they are not dangerous to your health. As long as it doesn’t prevent you from going about your daily business, there’s nothing to be alarmed about. However, if this problem persists and does not seem to be improving, you should see a doctor to find out what is causing the problem. As a reminder, it is very unlikely that CBD is responsible for the appearance of red eyes.
Is CBD completely legal?
Yes, CBD is completely legal as long as the finished product does not contain THC and it meets all the current European standards. CBD is not considered a narcotic, doping or psychoactive product. The French law authorizes its marketing under certain conditions: the cultivated cannabis plants must not contain more than 0.2% THC and the finished product must not contain any. THC, however, is still illegal in France. Its marketing and use can be punished by law. All the more reason to choose your CBD products carefully!
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.
