Why does weed make your eyes red? As any new user of cannabis can tell you, red eyes from smoking is almost impossible to avoid. Experts claim it is an entirely natural event that happens to all of us who smoke cannabis. Indeed, red eyes have nothing to do with smoking, and you can be punished or ridiculed for wearing so-called “weed eyes” in public.

For some cannabis-based products, users may experience an increase in heart rate and blood pressure. This effect is due to the presence of cannabinoids in the plant, responsible for several health benefits, such as pain relief and anti-inflammatory effects.

There is an increase in blood pressure and heart rate, but it usually takes five to ten minutes for the user’s heart rate to return to normal and blood pressure to drop.

Blood Pressure and THC

When blood pressure drops, blood vessels (capillaries), including the capillaries of the eye, contract, and the enlargement of the capillary, leads to increased blood flow, causing the eyes to turn red and the intraocular pressure to drop. Dr. Michael D’Agostino, a GYN physician and certified board member at the American Academy of Ophthalmology, says that cannabis can lower intraocular pressure and decrease blood flow in the brain that makes cannabis a potentially viable treatment for those whose eyes are diseased due to damage that can eventually lead to blindness.

The fact that THC in cannabis can lower intraocular pressure (IOP) is a significant reason many glaucoma patients try to use medical marijuana to treat and relieve the disease’s symptoms. Thus, a 2018 study at the University of Indiana found that cannabidiol (a non-intoxicating cannabinoid found in marijuana) could worsen the condition by increasing eye pressure. It is essential to know that this study contradicts and limits the claim that cannabis is beneficial for many things. He also explains why your eyes become “bloody” after smoking cannabis and why it can cause redness.

According to the American Academy of Ophthalmology (AOA), further research is needed to use cannabis as a treatment for glaucoma.

Like smoking cannabis, eating edible food can make your eyes red; this also depends on the amount of THC you consume.

Remember that it is not the smoke that makes your eyes red, but the cannabinoids that lower your blood pressure. The amount of THC you consume, the amount in which it lowers your blood pressure, and how red your eye turns depends on your body’s response to it.

Why are my eyes red after Smoking a Joint?

Red eyes can be because cannabis has a high cannabinoid content (i.e., it is abundant in THC, the active ingredient of cannabis) and is effective. If you are worried about redness in your eyes after recently using cannabis, you have reason to be concerned. One of the most common symptoms of smoking highly potent weeds is that the eyes become noticeably bloody after eating.

Cannabis – Induced eye redness usually lasts only a few hours and can be quickly resolved if you have the right tools.

Many other methods could help combat cannabis-induced bloodshot eyes, including washing face and eyelids with cold water, or merely using cannabis products with lower THC content. It is not a bad idea to have eye drops or sunglasses but look for eye drops specifically designed to reduce redness. The moisture stays in the eye for longer, usually about an hour or two, so it’s better for the eyes.

Typically red eyes are the result of smoking cannabis and not the product itself. Although it can come and go depending on the quantity and quality of cannabis (although some may seem less sensitive) and its use, experts say it is not guaranteed.

Some factors may come into play, but the typical reaction is a combination of factors, such as the amount of THC in cannabis, the quality of the product, and the presence or absence of other substances.

In short, THC lowers blood pressure, which in turn dilates blood vessels and capillaries. When blood flow to the eyes is increased, the capillaries dilate and lower the intraocular pressure. This increased blood flow causes redness, while the drop in pressure has the same effect that glaucoma patients benefit from. Smoking cannabis is also one of the main reasons why the plant is famous for treating diseases like glioblastoma, glia, retinitis pigmentosa, and gluconic acid.

However, it is possible that some people have allergies or irritations to cannabis or smoking in general and, therefore, have increased redness in their eyes. For sensitive individuals, however, this experience would likely be more of a side effect than a cause of red eyes or bloodshot eyes, and it is not the smoke itself that makes the eye red. This does not necessarily make cannabis harmless or perhaps even useful, caused by red eyes, but it makes it less of a problem.

There are a few simple steps you can take to minimize or decrease your eyes’ redness after smoking, such as using an eye mask, eye drops, or eye cream.

Do eye drops help with red eyes from Cannabis?

Keep an eye drop ready, especially for brands specifically designed to reduce redness, such as Laid-back Eye Drops. Choose a low THC strain: Strains with high CBD, CBN, and the like can be a desirable alternative for those who want to reduce red eyes during lying downtime.

Stay hydrated by plenty of water: The increased fluid intake can help to alleviate dryness. Just schedule your smoke seshes for an intimate moment at home and let it all flow. Ultimately, red eyes are not harmful and have no stigma attached to them, but they can cause a lot of pain and discomfort.

So your eyes are red, and you don’t know what to do? Mary Daze offers a few tips and tricks to quickly and safely make your eyes feel better!

  • Choose low or non-THC strains: using strains that are high in CBD and CBN will be ideal for patients looking to avoid red eyes altogether.
  • Always carry eye drops: there are certain brands specific to lessen the appearance of red eyes, with brands like Rohto being among the most popular choice in eye drops for stoners.
  • Drink lots of water! Increasing fluid intake can help relieve the dryness of the eyes.
  • Wait it out. With time, your eyes will finally transition from red, back to white.
  • Plan your cannabis sessions at home: the reddening of your eyes from marijuana use is not harmful, and if you stay in the warmth of your own home, you will not have to worry about what others may think!

Another benefit marijuana brings to the eyes is heightened night vision. As pot connects the cannabinoid receptors in the eyes, vision becomes clearer in lower lighting conditions. Scientists have studied this aspect of cannabis for over three decades. For example, a pharmacologist during the 1990s, M.E. West observed fishermen in Jamaica who had an “uncanny ability to see in the dark” after eating a cannabis edible.

Cannabis Allergies and Red Eye Syndrome

A small percentage of the population has cannabis allergies. Pot creates pollen, and that can produce an allergic response in some people. Though, if you have an allergy to marijuana, it will be a lot more than just red eyes, such as hives, swelling, or itchy skin….

Typically red eyes are the result of smoking cannabis and not the product itself. Although it can come and go depending on the quantity and quality of cannabis (although some may seem less sensitive) and its use, experts say it is not a guaranteed occurrence.

Smoking cannabis is also one of the main reasons why the plant is famous as a treatment for diseases such as glioblastoma, glia, retinitis pigmentosa, and gluconic acid.

This reaction explains the difference in intensity of red eyes: If a person’s eyes are red after ingestion of a high THC strain, they may smoke a low THC strain and have little or no red-eye. This explanation also explains why people can become exhausted when smoking is scarce or when eating edible foods.

However, it is possible that some people have allergies or irritations to cannabis or smoking in general and therefore have increased redness in their eyes. For sensitive individuals, however, this experience would likely be more of a side effect than a cause of red eyes or bloodshot eyes, and it is not the smoke itself that makes the eye red.

What Causes Red Eyes?

Several factors can cause your eyes to appear red or bloodshot after you use marijuana. The main reasons red eyes occur are:

  • Lowered Blood Pressure: One of the reasons medical cannabis is a beneficial treatment is THC’s ability to lower blood pressure. It’s particularly helpful as a glaucoma medication, as the disease is caused by increased intraocular demand. However, when blood pressure is lowered, it causes the vessels and capillaries to dilate. This elevated blood flow causes eyes to appear red.
  •  Smoke Irritation: Some eyes are just sensitive to smoke — it doesn’t matter if it is marijuana, tobacco, or a campfire, their eyes will get red and irritated.
  • Allergy: If you have an allergy to cannabis or smoke, using this plant or smoking, it will more than likely make your eyes red. Nevertheless, allergies to weed are infrequent.

 

Get Rid of Those Red Eyes

If you dont you have an allergy to cannabis, the cause for red eyes is harmless. For some, it’s even helpful. The best thing to do is just to let it fade away naturally. This isn’t a long-term side effect — it usually wears off after a few hours.

However, if you need to go out and about, you don’t necessarily want to leave the house with bloodshot eyes. Here are some tips on how you can reduce the look of red eyes:

  • Try a Different Strain: If the strain you use is high in THC, it doesn’t mean it’s a smokable or edible, it’s more likely to make your eyes red. Try strains high in CBD or CBN instead.
  • Switch Up Your Ingestion Method: If smoke irritates your eyes, try a different method of ingestion, like vaping or edibles.
  • Use Eyedrops: Using eye drops particularly designed to reduce eye redness can help. They constrict the vessels in the eye, thus causing them to appear less red. It’s a good idea to carry these around with you and use the drops multiple times a day. Don’t share your drops with others, as this can lead to eye infections.
  • Drink Lots of Fluids: If you’re dehydrated, smoke can dry out your eyes, causing them to appear redder.
  • Cover Them Up: Although it’s cliché, if you’re outside, try wearing sunglasses. This will prevent others from seeing the redness in your eyes.
  • Apply an Ice Pack: Use this simple home remedy for five minutes on each eye to reduce redness.
