Cannabidiol, generally known as CBD, is a powerful cannabinoid found in hemp plants, with many proven health benefits. CBD has become a welcome addition to the lives of millions, due to its non-intoxicating and therapeutic effects.

CBD provides relief from any ailment, and it also offers solutions to many health problems that you often experience in daily life. Anyone can enjoy health benefits from CBD without the risk of addiction or overdose.

CBD is derived from the Cannabis plant, and when it comes to taking cannabis products, there’s a common misconception that it can make your eyes red. Due to this, many people are in doubt and wondering about whether CBD can turn your eyes red.

Let’s start with a piece of good news, CBD doesn’t make your eyes red.

Read on to know about what causes red eyes after consuming CBD. How to get rid of red eyes after taking CBD?

CBD, Cannabis, and Red Eyes: Is CBD Responsible for Bloodshot Eyes?

CBD, Cannabis, and Red Eyes:

Is CBD Responsible for Bloodshot Eyes?

‘According to research on CBD, it doesn't cause 'red eyes' because it does not interact with cannabinoid receptors in the same way as THC does’

The cannabis plant has the potential to alleviate chronic pain, stress, and anxiety, and can promote better and more restful sleep. Cannabis contains two active substituents, CBD and THC.

CBD is widely known for its therapeutic benefits, so what causes red eyes?

It’s actually the ‘THC compound’.

Inflamed, watery, and red eyes are always associated with high levels of THC, the higher the THC content, the greater the impact. On the other hand, CBD doesn’t dilate blood vessels and it has no role in causing bloodshot eyes.

Therefore, you can introduce CBD into your daily routine without worrying about irritated, watery, and red eyes.

Why does THC Cause Red Eyes?

THC interacts with cannabinoid receptors and lowers blood pressure, which causes blood vessels to dilate. The dilation or widening of blood vessels increases blood flow in your eyeball, which causes red eyes, while a sudden drop in blood pressure causes dizziness.

Does Smoking CBD Make Your Eyes Red?

Although smoking CBD does not induce red eyes, it can cause inflamed and watery eyes.

When it comes to red eyes, it's not always due to smoking or ingesting CBD, but these are cannabinoids that can create dryness in the eyes. However, puffy eyes can also be caused by an allergic reaction to cannabis, which can increase eye redness.

Does CBD Oil Affect Your Eyes?

CBD oil increases eye pressure which may affect your vision, even if you don’t have glaucoma. As CBD oil can contain contaminants that can affect your vision badly, it’s important to purchase CBD oil from known brands only.

However, CBD oil which follows the legal limit of THC will not cause any problems for you.

Do CBD Edibles Make Your Eyes Red?

Yes, it's possible CBD edibles can make your eyes red, depending on the type of CBD edibles you consume.

THC is the molecule responsible for bloodshot eyes after cannabis. So, any CBD edible containing more THC level could cause red eyes, however, red eyes aren’t dangerous for your health.

Does Delta 8 Make Your Eyes Red?

Yes, Delta 8 can cause your eyes to turn red.

Delta 8 cannabinoids react with our body receptors, which control saliva production and blood flow to the eyes. According to research, Delta 8 can cause dry eyes, increased heart rate, tiredness, headaches, nausea, and in some cases, it can even lead to hallucinations.

Red Eyes After Taking CBD

If you experience red eyes after taking CBD products, it might be a short-term side effect of THC, which means that the product has a higher THC content.

You should check the source of CBD whether it is hemp-derived or marijuana-derived. Also, the CBD industry is unregulated, with many unauthorized sellers producing CBD products that may contain higher THC levels without your knowledge.

If CBD contains more than 0.3% of THC, you’ll definitely experience red and watery eyes. It’s better to purchase all CBD products from reputable brands.

How to Get Rid of Red Eyes?

Consuming too much THC or using CBD with tobacco, can induce slightly painful and bloodshot eyes. You can reduce inflammation and redness by following tips:

Use Quality Eye Drops: You can get rid of red eyes within minutes by putting a few eye drops in your eyes.

Stay Hydrated: Drink plenty of water, it can help alleviate dryness in your eyes.

Consume Vasoconstrictor-inducing Foods: Eat chocolates, salty snacks, processed meat, and all caffeinated foods, and drinks can cause the blood vessels to narrow.

Be patient: Sometimes all you need is some rest while avoiding exposure to screens and sunlight for a few hours.

Are Red Eyes Bad for My Health?

Many people are concerned about having red eyes after using CBD oil. While this will not happen with a pure CBD product,

You shouldn’t worry about it because it's a common side effect of THC, and red eyes aren't harmful to your health.

Dryness in the eyes can also cause slightly painful red eyes, and it’s unlikely that CBD is responsible for the redness in your eyes.

However, if this condition persists and does not appear to be improving, you should consult a doctor to determine the source of the problem.

Pure CBD Doesn’t Make Your Eyes Red

The marijuana plant contains higher levels of THC which lowers blood pressure and dilates blood vessels.

The red eyes can appear shortly after consuming marijuana-derived products because THC increases blood flow throughout the body.

On the other hand, CBD is derived from hemp, which contains less than 0.3% of THC, so you shouldn’t worry about redness and dryness in the eyes after consuming CBD.

However, full-spectrum CBD oil contains 0.3% of THC, if you ingest a higher dosage of CBD, it’s possible that it will turn your eyes red. Consuming pure CBD or isolated CBD doesn’t make your eyes red.

Is CBD Completely Legal?

CBD is well-known for its health benefits, but as its demand rises, many consumers are willing to ask if using CBD is legal.

Yes, CBD is completely legal in all 50 states.

The 2018 farm bill federally legalized CBD but every state imposes different restrictions, in the United States, you may or may not be able to legally purchase CBD.

The Cannabis plant contains active substituents such as CBD and THC.

Cannabis with less than 0.3% of THC is considered Hemp, while more than 0.3% falls in the category of Marijuana.  Keep in mind that the federal government only legalized hemp-derived CBD, not marijuana products, which means you can legally obtain CBD product as long as it doesn’t exceed the legal limit of THC.


Does CBD cause eye redness?

According to research on CBD, it doesn’t cause eye redness. If you experience dry and itchy eyes after consuming CBD oil, it’s possible that CBD contains high levels of THC.

Since CBD is non-intoxicating, it doesn’t make you high or dilate blood vessels, in fact, it has no role in causing bloodshot eyes.

The red and watery eyes are always associated with the THC components, which makes you feel high.

Does CBD affect your eyes?

There’s currently no evidence to suggest that CBD directly affects your eyes or vision. According to a study, CBD increases eye pressure. High eye pressure is a major risk factor for glaucoma, which is one of the leading causes of blindness.

We can say that excess use of CBD will definitely increase eye pressure which may affect your eyes and vision and can worsen your eye problem.

What are the side effects of CBD?

Overall, CBD is a safe medication and doesn’t cause any side effects, but high dosages can affect your health. The possible side effects of CBD are:

  • Diarrhea
  • Dry mouth
  • Light-headedness, drowsiness, and dizziness
  • Change in appetite
  • Low blood pressure

CBD can also interact with other medications. However, these side effects are well-tolerated and can disappear after 2-3 hours.

Does CBD make your eyes dry?

CBD doesn’t make your eyes dry.

According to some studies, topical CBD may help restore the function of the Meibomian glands and alleviate dry eyes.

In short, pure CBD will not make your eyes red or dry, no matter how much you smoke, ingest, or use it.

Bottom Line

According to studies, CBD does not cause red eyes, because it does not interact with cannabinoid receptors in the same manner that THC does.

It’s actually the ‘THC compound’.

Red, dry and inflamed eyes are always related to higher THC levels, the more THC content, the more severe the effect. However, CBD does not widen blood vessels and does not contribute to the appearance of bloodshot eyes.

In a nutshell, you can include CBD in your daily activities without worrying about itchy, watery, and red eyes.
