So you’ve heard the tales — or lived them yourself — that when you partake in some type of hemp product, the dreaded red eyes appear. Some people believe that smoke causes red eyes. Novices may dive down the Google rabbit hole to figure out if weed is damaging their eyes (it’s not). 

In this article, we’ll answer the question: does delta-8 make your eyes red? We’ll dig into what delta-8 is, why people get glossy eyes from weed, how you might prevent it, and the different consumption methods to support your needs and lifestyle. 

What is delta-8? 

Delta-8 is a type of THC. No, it’s not the same as delta-9, and yes, it is legal in most states as long as it adheres to the federal law of below 0.3% delta-9 THC. Delta-8 is found in small amounts naturally in the hemp plant, so the highest quality brands can convert delta-8 from other phytocannabinoids like delta-9 and CBD. 

Delta-8 vs. Delta-9: What’s The Difference?

The main difference between delta-8 and delta-9 is the location of the double carbon bonds and how the high presents itself. Molecularly, the double carbon bond of delta-8 is located on the eighth carbon. Not surprisingly, it’s located on the ninth carbon for delta-9. 

Does delta-8 make you high?

It sure can. The high is the most exciting difference between delta-8 and delta-9 because you can get high legally with delta-8. It’s also one of the smoothest highs, leaving you feeling light and relaxed. The delta-8 high doesn’t have some of the common side effects of a delta-9 high, like couchlock and anxiety. It can be tailored to fit your needs, whether you want a small amount first thing in the morning or pop a gummy to unwind before bed.

Does Delta-8 Make Your Eyes Red?

Why do eyes get red after smoking hemp products? It isn’t the smoke itself. It’s dependent on the amount of THC found in the product and its ability to lower blood pressure, which causes your eyes and capillaries to dilate — a process called vasodilation. The dilation causes more blood flow to the eyes, which, in turn, can cause glossy eyes from weed. 

Does delta-8 make your eyes red? It can. It all depends on your body chemistry (do you usually get edibles red eyes)? It also depends on how much delta-8 you’re consuming. Some say they experience no or less red-eye compared to taking a higher amount of a delta-9 product. If you’re consuming a high-quality and legal delta-8 product, it will have less than 0.3% delta-9 THC. 

Delta-8 Effects

You know what delta-8 is. Now it’s time for the fun part — delta-8 effects. The best way to understand the delta-8 effects is, of course, to experience them for yourself. But if you want a small idea of what you might experience with delta-8, keep reading. 

For many people, delta-8 is an uplifting and soothing experience. How you feel will greatly depend on a few factors like how much you consume, how much you’ve eaten that day, body chemistry, and things of that nature. 

If you wake up in the morning feeling without, yet you still need to be a functioning human and go about your day, delta-8 may be something to try. Take a small amount (you’ll want to experiment beforehand to know what feels best) to start your day, and allow it to soften things. If you only take a little bit, does delta-8 make your eyes red? No, it shouldn’t, but again, only by learning your body and how it responds to the delta-8 will give you the truest answer. 

Perhaps you want to get high-high, like a delta-9 high, well… You can’t. But that’s only because you can have a much better high (yes, a high-high) than a delta-9 high. Is delta-9 bad for you? No, not in moderation — like most things. If you’re at the end of the day or the morning when nothing is pressing, you can take more delta-8 and experience a more intense high that still feels smooth. You don’t have to worry about getting knocked on your bum like delta-9. 

Below, we’ll talk about how to potentially prevent glossy eyes from weed and the different consumption methods. Each one will take a different amount of time to take effect. We’ll answer some questions like: why do eyes get red after smoking, and do carts make your eyes red?

Preventing Edibles Red Eyes

Does delta-8 make your eyes red? That depends. Let’s discuss some strategies you can implement to potentially prevent glossy eyes from weed. 

  • Eye drops. Quickly soothe your eyes with eye drops. There are certain types of eye drops specifically for easing red eyes. 
  • Stay hydrated. Drinking water is vital for all kinds of body functions, and it only helps your cause by guzzling down the H2O. 
  • Smaller amounts of delta-8. Lessen those edibles red eyes by taking less delta-8. Test out your limits by trying different amounts. 
  • Go to sleep. Sometimes you just have to wait it out.

When looking for delta-8 products, always go for the highest quality you can find. How do you determine quality? By going straight to the source. 

Third-party lab testing. Third-party lab testing results will be your first indicator of quality. Delta-8 isn’t a regulated market, so brands can put whatever they want on labels.

Different Consumption Methods And How They Work

Each of the consumption methods for delta-8 will have different results and effects. Each has its benefits, and the most important thing is finding a high-quality delta-8 product. Do carts make your eyes red? Let’s find out. 

The three most popular delivery methods for delta-8 are: 


Edibles come in all flavors and consistencies. You can find delta-8 gummies, brownies, cookies, lollipops, etc. An edible is consumed like food and digested like food. What this means is that the activation time is typically longer than other delivery methods. Activation times can range anywhere from 30 minutes to 2+ hours, so don’t go pop another gummy 30 minutes thinking the first one didn’t work (unless you want to potentially go on a ride). 

The edibles high is smooth and longer-lasting than other forms of delta-8 and our favorite way to enjoy delta-8. Does delta-8 make your eyes red? The edibles red eyes may show up if you consume a high amount of delta-8, so you’ll have to experiment with what’s best for your body. 


Tinctures are a simple way to get delta-8 into your body. You just drop it into your mouth and let it get to work. Activation is relatively quick, around 10 to 15 minutes, but the high doesn’t last quite as long as a delta-8 gummy. You can enjoy different flavors of a tincture, add it to your morning routine for a boost, or take it before bed. 


Smoking delta-8 is a fast-track way to get it into your system since it’s going straight to the lungs. Do carts make your eyes red? Depending on how much you take and how your body reacts to it, they can. The drawback to inhaling delta-8 is that combustion is still happening in your lungs, which isn’t so great, even if the product itself is wonderful. 

Inhalation activation can happen within minutes, which is helpful if you really need the support of delta-8 at that moment. You may wonder if red eyes differ between vaping and smoking flower, and the answer is the same. Why do eyes get red after smoking? Your eyes get red because of vasodilation — the dilation of the blood vessels leading to increased blood flow to the eyes. Certain amounts of THC encourage this process to happen in the body. So the THC is causing the red eye, not the smoke (although smoke can sometimes irritate eyes depending on who you are).
