Does CBD Make Your Eyes Red?

Due to it’s non-intoxicating yet therapeutic effects, CBD has become a welcome addition in the lives of millions. The benefits to be gained from CBD, a compound which carries no potential for abuse, addiction or overdose and provides a safe, gentle and effective remedy for many of life’s challenges, are huge.

As CBD is derived from cannabis plants there are misconceptions with the intoxicating compound also found in cannabis called THC. This misconception often stops many from experiencing the benefits of CBD due to not having important concerns answered fully.

A common physiological reaction to using intoxicating cannabis containing high levels of THC is ‘red eye’. This can occur with marijuana use as THC reduces blood pressure causing the blood vessels within the eye to dilate or become larger, increasing blood flow causing noticeable redness.

Research on CBD has concluded that CBD does not cause ‘red eye’ as it does not bind to receptors in the same way as THC.

Our physiological response to CBD is completely different to THC. CBD does not make your eyes dilate and as it is non-intoxicating it will also not make you feel high.

One caveat is that if you are using full spectrum CBD (CBD that contains the full range of compounds from the cannabis plant) the presence of very low levels of THC (not enough to make you high) may be enough to affect ‘red eye’. Full spectrum products do offer a boosted effectiveness of CBD compared to CBD isolate products. THC and other minor compounds create an entourage effect on CBD making it more effective. THC also has excellent pain killing properties even at small levels so the benefits can outweigh any potential red eye.

Factors also to be considered for causing ‘red eye’ include allergies and illnesses which should be checked out by your medical professional.

Does CBD Make Your Eyes Red?

The stereotypical look of a cannabis user is associated with red, droopy eyes and a goofy smile. While this is true for most novice marijuana smokers, red eyes don’t go hand in hand with CBD use.

In fact, we don’t know any person who would get red eyes after taking CBD oil.

Does it mean that CBD doesn’t make your eyes red at all?

Or is it true only for certain formats and products?

In this article, we compare the effects of CBD and THC on intraocular pressure, explain why you can get red eyes after using a CBD product, and share handy tips for managing this symptom.

Does CBD Make Your Eyes Red?

No, CBD doesn’t make your eyes red because it doesn’t bind to the cannabis receptors that are responsible for this effect.

CBD may reduce the overall blood pressure, but when it comes to intraocular pressure, it doesn’t share the same properties as THC.

Speaking of which, let’s take a look at the real reason why cannabis can make your eyes red.

The Red Eye Effect Comes from THC

THC is the only cannabinoid responsible for giving you red eyes.

Don’t worry, it’s not a negative effect.

On the contrary, red eyes are caused by decreased intraocular pressure, which improves blood flow to the eye by dilating blood vessels. With more blood being pumped to your eyes, they start to turn red.

That’s why cannabis smokers often have red eyes after a few puffs. The intensity of this effect depends on your tolerance and your body’s unique chemistry, but it’s a common phenomenon among cannabis users.

However, this isn’t the only difference between CBD and THC.

Here we shed more light on both cannabinoids.

The Difference Between CBD and THC

CBD and THC have a lot of similar therapeutic properties. Both can be used to alleviate a wide range of ailments, both physical and psychological.

That being said, their effects on the brain are completely different:

CBD is a non-intoxicating cannabinoid, meaning it won’t get you high. That’s because CBD doesn’t interact with cannabinoid receptors in the brain. Instead, it enhances their signaling by interacting with the enzymes and neurotransmitters in the endocannabinoid system (ECS) — the major regulatory network in all mammals. Although CBD doesn’t make your eyes red or induce euphoria, it allows you to relax, reduce anxiety, and alleviate pain. It also has remarkable anti-inflammatory, antioxidative, and neuroprotective effects on the brain.

Cannabis has been consumed for thousands of years for its medicinal and psychoactive properties. It binds to cannabinoid receptors in the brain, leading to feelings of euphoria, deep relaxation, elevated mood, sharpened senses, and altered perception of time. From a medicinal perspective, THC has the potential to relieve pain, depression, insomnia, and assist in the treatment of cancer, autoimmune disorders, and neurodegenerative diseases. Higher doses of THC carry a risk of inducing anxiety and paranoia, which are caused by the biphasic nature of this compound.

How Does CBD Work in the Body?

As mentioned, THC and CBD look similar at first glance. But when you examine them more carefully, you’ll notice that they use different mechanisms to achieve their effects.

One of the most noticeable differences is the chemical makeup of CBD, which comes with an extra layer of hydrogen — allowing the user to enjoy the myriad of benefits of using cannabis without disrupting cognitive capacity.

CBD is indirectly related to the endocannabinoid system. It helps optimize its functioning by enhancing the activity of cannabinoid receptors and endocannabinoids.

People usually take CBD for anxiety, depression, pain, autoimmune diseases, and neurological conditions.

However, the dilation of blood vessels and the red-eye effect aren’t part of its effects.

Why Do Marijuana Users Have Red Eyes?

The main reason why marijuana makes your eyes red is the effect of THC on blood flow to the eyes. The higher the THC potency in your strain, the greater the effect.

Your eyes may also become red from tobacco smoke, but this comes as a result of irritation rather than the dilation of blood vessels. If you combine cannabis with tobacco, the bloodshot eye may be even more visible.

CBD Doesn’t Make Your Eyes Red: Watch Out for Scams

If you’ve consumed a CBD product and got red eyes afterward, you should check if your product comes from hemp or marijuana. Many CBD products sold online and locally are mislabeled, so there’s a risk of cross-contamination with THC.

Not only can such CBD products make your eyes red, but they can also get you into trouble with the law. CBD extracts with a THC content above 0.3% are considered ‘marijuana’ and classified as Schedule I drugs (federally illegal).

Always get your CBD oils from reputable manufacturers who provide updated, third-party lab reports for every product they offer.

How to Manage Red Eyes After Cannabis

Smoking marijuana, consuming marijuana-derived CBD oil, or smoking CBD hemp flower with tobacco can give you red eyes. While not negative per se, the redness and dryness can cause unnecessary discomfort.

Here’s how you can deal with this effect:

  • Use a vasoconstrictor: certain foods, such as chocolate, can constrict blood vessels in the eyes, reducing their redness.
  • Take eyedrops: putting eyedrops in your eyes will reduce the dryness and redness by relieving inflammation in the irritated spot.
  • Wait until the effect wears off: red eyes won’t linger forever. Sometimes, you need to be a bit patient, and red eyes will go away. In the meantime, don’t expose yourself to the sun for a few hours, as it can further irritate your eyes.

Are Red Eyes A Good or Bad Sign?

Many people are afraid of getting red eyes after taking CBD oil. While this won’t happen with a legitimate CBD product, the fact that marijuana makes your eyes red isn’t anything bad.

It’s actually a good sign because THC relieves intraocular pressure. When this pressure builds up in the eye, it can cause pain and nerve damage, resulting in glaucoma.

However, smoking marijuana only provides short-term relief; it’s better to eat a cannabis-infused edible and enjoy the reduction of blood pressure for up to 10 hours.

Is CBD Legal?

Yes, CBD is legal in all 50 states, but it must come from hemp and contain 0.3% of THC or less. Hemp-derived products were legalized by the 2018 Farm Bill; since then, CBD has been classified as a novel food or health supplement.

Will Smoking CBD Make Your Eyes Red?

Smoking CBD hemp flower shouldn’t make your eyes red as long as it contains only a trace amount of THC. Some people are allergic to certain terpenes in hemp, so if your strain causes red eyes, switch to another strain.

And don’t mix CBD with tobacco. It will ruin the taste of your spliff, not to mention the obvious health risks of smoking tobacco.

CBD and Red Eyes: FAQ

Still not sure if CBD will make your eyes red and lower than your profile? These three questions will dispel your doubts:

1. Does CBD Affect Your Eyes?

The effects of CBD on the eyes are under-researched, but since CBD counteracts many effects of THC, it’s possible that it might worsen existing symptoms of glaucoma. However, this was shown only in one study; we need more quality research to conclude the effects of CBD on intraocular pressure.

2. Can CBD Help with Cataracts?

There’s not enough evidence to confirm that CBD might help with cataracts. The condition appears to stem from oxidative stress, and the impact of CBD on oxidative stress and inflammation is well-researched. However, no study has yet touched on the subject of using CBD for cataracts.

3. What Are the Side Effects of CBD?

CBD has a favorable safety profile. It comes with a few mild side effects, most of which are nonexistent in regular doses. At present, CBD is known to cause dry mouth, changes in appetite, sedation, and diarrhea when consumed in excessive amounts.

CBD can also negatively interact with many prescription medications. Always talk to your doctor before adding CBD oil or to your regime.

CBD and Red Eyes: Bottom Line

CBD doesn’t make your eyes read because it doesn’t use the same mechanism as THC.

In fact, the effects of both compounds on the intraocular pressure are completely different.

If you’re worried about getting red eyes after taking CBD oil, know this — as long as you’re using a lab-tested product, you shouldn’t get this effect.

And if you experience red eyes after consuming marijuana, don’t worry, it’s actually a good sign because THC relieves pressure from them — preventing nerve damage and reducing the risk of glaucoma.

We hope this article has helped to address the question of whether or not CBD makes your eyes red. Always make sure to choose lab-tested products so that you reap the benefits without the bloodshot eye effect.

CBD Red Eyes | How are the Eyes after smoking CBD Weed? Benefits or red eyes?

Medical cannabis has made spectacular advances in recent years around the world. In France, on the other hand, it must be admitted that weed users are still very often stigmatized as being “drug addicts”. As a result, smokers, vapers and other consumers of medical or recreational cannabis often want to keep a low profile. The problem: red eyes! These famous “exploded” eyes characteristic of the joint smoker. So yes, it’s true that you can have red eyes for other reasons than having consumed weed. But still, it is a distinctive sign that can make the person concerned uncomfortable. Don’t panic, solutions exist to overcome this discomfort without depriving yourself of the effects and organoleptic qualities of marijuana. And why not try a CBD product?

Why do eyes turn red when smoking, inhaling or ingesting cannabis?

Smoke from a joint (marijuana cigarette) is often the culprit for occasional eye irritation. Hence the red color they take, especially in an enclosed environment. But, it is not the only one responsible for this inconvenience and especially, not the main one.

In cannabis, there are a number of compounds that are more or less active and in varying concentrations. Among these substances, there are 3 main groups:

  • Cannabinoids such as THC (tetrahydrocannabinol, psychoactive compound), CBD (cannabidiol) and CBN (cannabinol) are the best known and most concentrated of the hundred or so listed to date.
  • Terpenes, essentially responsible for the organoleptic properties of plants (taste and smell) such as myrcene and pinene.
  • Flavonoids, essential compounds for reproduction thanks to the colors they give to

    attracting pollinators.

THC is the most concentrated naturally active compound in classic weed. It acts directly on the CB1 and CB2 receptors of our endocannabinoid system (ECS). Thus, it generates the psychoactive and euphoric effect which made its bad reputation; but not only! Among the different potentials induced by the consumption of THC, one of them is responsible for the red color that the eyes take. Indeed, the herb illegal in France or tolerated in countries open to medical cannabis, has moderate or high THC content. These concentrations cause a slight decrease in blood pressure (1) responsible for the dilation of blood vessels. The eyes are not spared by this vasodilatation, the volume of blood is greater in the vessels, and therefore more visible. The eyes then appear blood red.

While this vasodilation is sometimes a nuisance for cannabis users who prefer discretion, the THC-induced reduction in blood pressure can have real benefits. It highlights its potential positive effects (2) on diseases such as


degenerative pathology of the optic nerve characterized by high blood pressure in the eye.

Finally, if we put aside allergies and other rare pathologies, the last cause of red eyes is dehydration. Ocular vasodilation is the main reason for “popping eyes” but the body uses water to eliminate THC from the blood. This sample may cause slight eye irritation due to occasional dehydration.

How long do the eyes stay red?

There are several factors that affect how long a person will have red eyes from conventional cannabis use:

  • individual sensitivity: natural blood pressure, potential allergies, general health, fatigue, etc.
  • the amount of THC products smoked, inhaled or ingested
  • Cannabis varieties: THC content
  • the parts of the plant consumed: seeds, flowers, leaves.
  • the mode of absorption: smoking and vaping tend to “pop” the eyes more than ingestion.

It is impossible to give a precise duration of the “red eye” effect. However, one thing is certain: This phenomenon eventually disappears after a while.

Is this mild side effect really a problem for you? Don’t panic, it is possible to reduce the effects of eye redness or to accelerate the return to normal of blood pressure in the eye. If not, switch to CBD cannabis, 100% anti-red eye hemp!

How not to have red eyes after smoking, inhaling or ingesting cannabis?

As there are several causes of red eye, there are just as many solutions:

  • smoke: avoid smoking weed, prefer vape or ingestion.
  • Dehydration: remember to drink water from the beginning and during marijuana use.
  • vasodilatation: avoid using THC.
  • Irritation due to all these factors: chemical eye drops, physiological liquid or sunglasses!

Finally, the best way to avoid red eyes while consuming cannabis is to opt for CBD products.

Why don’t I have red eyes when I smoke?

With the “why and how” of marijuana-induced eye redness understood, it is legitimate to ask the question “why don’t I have it?” Aside from rare cases of allergies to certain compounds in the cannabis plant, smoking and dehydration (which only cause temporary redness of the eye), there is only one reason not to have red eyes after smoking weed. The latter is devoid of THC.

Smoking CBD cannabis flower varieties found on the European market such as those offered by our online shop, Bistrot CBD, will not cause ocular vasodilation. Indeed, for meet the French legislation in force, their concentration in THC is almost null (< 0,2%).

The taste, smell and presence of other cannabinoids give CBD cannabis the illusion of a traditional joint (without the psychoactive effects). However, it is strongly discouraged to smoke weed, even legal (risks due to combustion products on health)! Depending on the CBD product (seeds, flowers,
CBD oil
(seeds, flowers, e-liquid..), another mode of consumption will be preferred. The current diversity of CBD products allows among others: vaping,


ingestion (cooking, herbal tea), sublingual drops and skin application.

So, how about a vape, a space-cake or a CBD herbal tea? Relaxation and guarantee without eye redness !

FAQ: CBD and red eyes

Est-ce que le CBD dilate les pupilles?

La dilatation des pupilles est un phénomène fréquanent dans la vie de tous les jours. Elle peut être causée par une simple variation de la lumière mais également par des drogues psychotropes telles que le cannabis ou la cocaïne. En France, les produits au CBD ne contiennent pas de THC, ils n’entrainent pas de dilatation de la pupille.

Quelle sensation procure le CBD?

La sensation la plus connue que procure le CBD est une intense relaxation physique et psychique.

Comment fumer mon CBD?

Comme un joint classique, les fleurs et la résine de CBD peuvent se fumer en cigarette ou pipe. Cependant, cette pratique étant néfaste pour la santé (combustion), le CBD peut être vaporiser, vaper (e-liquide) ou inhaler.

Quels effets a le CBD?

Le cannabidiol (CBD) est particulièrement connu pour ses effets relaxants menant au bien être.

La détente que procure le CBD est essentiellement due à son effet :

  • analgésique
  • anxiolytique
  • anti-nauséeux
  • anti-inflammatoire

Est-ce que le CBD sent?

La molécule de CBD (cannabidiol) en tant que telle est inodore. En revanche, la majorité des produits au CBD (huile, fleurs, résine, rocks, ..) étant constituée de matière végétale issue du chanvre, ces produits sentent forts!

Est-ce que le CBD se fume pur?

Le CBD peut très bien se fumer pur. Cependant, les risques pour la santé de fumer du CBD ne viennent pas majoritairement du tabac mais de la combustion. Fumer du CBD pur ou ajouté au tabac est donc fortement déconseillé. Préférez plutôt les bienfaits des produits au CBD par vaporisation ou ingestion.

Pourquoi prendre du CBD?

Pour ses nombreuses propriétés (anxiolytique, anti-inflammatoire, analgésique, etc), le CBD peut être intéressant pour :

  • soulager certaines douleurs (fibromyalgie, arthrose, . )
  • diminuer l’effet du stress (dépression, anxiété, . )
  • réguler l’appétit (chimiothérapie, boulimie, . )
  • favoriser l’endormissement (insomnie, troubles du sommeil, . )
  • se relaxer intensément (tensions musculaires, nervosité, . )

Est-ce que le CBD fatigue?

Le CBD est réputé pour ses vertus relaxantes particulièrement efficaces pour lutter contre l’insomnie. Si grâce à ses propriétés, le CBD permet à son consommateur d’acquérir un meilleur sommeil, il ne le provoque pas.

Dans certains cas, le CBD est susceptible d’entraîner une légère somnolence. Cette dernière peut découler directement de l’état d’extrême relaxation que le CBD engendre! Afin de ne prendre aucun risque, il est donc déconseillé de prendre du CBD avant de conduire car, si le CBD ne fatigue pas, en revanche, il détend profondément.

Est-ce que le CBD est détectable au test salivaire?

Malgré son origine cannabique, le CBD est une molécule complétement légale en France en tant que telle. De ce fait, les dépistages tels que les tests salivaires ne sont pas destinés à déceler cette molécule.

Consommer du CBD ne vous mettra pas dans l’illégalité et ne vous rendra pas positif si le produit au CBD consommé ne contient pas de THC. Afin de ne prendre aucun risque quant à la présence de THC il est alors nécessaire d’acheter un produit au CBD dans une boutique française sérieuse respectant la législation en vigueur.
