- Eye drops like artificial tears, a cold compress and splashing cold water on the eyes are a few ways to decrease how strongly you experience eye redness.
- Both smoking weed and eating edibles that contain THC can make your eyes red, but it may take longer for high eyes to occur when consuming edibles.
Why Weed Causes Red Eyes
It’s no secret that smoking cannabis can make your eyes red, but why do high eyes even happen?
It all comes down to THC. The cannabis compound famous for its intoxicating effects also causes blood vessels and capillaries in the eyes to expand, ultimately leading to the bloodshot eyes THC is also famous for.
This occurs because THC lowers blood pressure, which dilates blood vessels and increases blood flow throughout the entire body. The result is red, dry eyes, also known as bloodshot eyes.
As blood pressure begins to lower after THC consumption, it causes blood vessels and capillaries to dilate, leading to an almost immediate increase in blood flow to the eyes. The result is the red, dry eyes, also known as bloodshot eyes, that are characteristic of cannabis consumption.
Vasodilation, or the widening of blood vessels, affects not only the eyes but also the entire body. This is why cannabis consumption can lead to a drop in blood pressure and an increased heart rate.
So, the next time your eyes turn red after smoking weed, remember that it’s all thanks to the vasodilation caused by consuming THC as blood vessels begin to widen as blood flow increases.
While there are numerous chemical compounds in cannabis, THC is the primary cannabinoid to make your eyes red, as it is behind the increased blood flow that causes blood vessels to dilate. Other cannabinoids may make your eyes red, but THC remains the most significant factor.
Understanding the role of THC in causing red eyes can help you make informed decisions about your cannabis consumption.
Always consult with a licensed physician if you’re using medical marijuana for specific conditions, as they can guide you on the appropriate dosages and potential side effects, including eye redness.
The Impact of Cannabis on Glaucoma Patients
Cannabis has long been believed to support glaucoma by lowering intraocular pressure.
The decrease in intraocular pressure is primarily due to the increased blood flow and relaxation of eye capillaries, which is basically the same thing that causes eye redness.
This is why medical marijuana has been used to support the degenerative eye condition for decades. Of the 33 states that have passed medical marijuana use, 29 of them list glaucoma as a qualifying condition.
Maintaining a healthy IOP is critical for preserving vision in individuals with glaucoma. By lowering intraocular pressure, using medical cannabis may help prevent vision loss associated with this condition.
The pressure relief provided by cannabis typically lasts approximately 2-4 hours in most cases. So, while cannabis consumption may temporarily lower intraocular pressure, the short-lived nature of its effects can make it less than ideal for those interested in long-term relief.
Further research is needed to understand the potential benefits and long-term effects of cannabis use for those suffering with glaucoma.
Do Edibles Make Your Eyes Red?
Wonder if eating THC-infused edibles can also cause eyes to turn red?
If edibles are your thing, you’ve probably noticed that you definitely get a case of stoned eyes after the edibles kick in. If you consume cannabis edibles that contain THC, your eyes will absolutely become red.
Lower blood pressure is still a thing in THC edibles, meaning they still affect blood vessels which lead to red eyes. That being said, things like absorption rates, metabolism and how much CBD content is in the edible can influence the intensity of redness.
Edibles may also take longer to cause red eyes due to their delayed onset compared to smoking. As with smoking cannabis and using other types of cannabis products, it’s vital to be aware of the potential risks associated with edibles and consume them responsibly.
Quick Remedies To Reduce Eye Redness
Want to get rid of stoned eyes fast?
If you’re looking to alleviate high eyes quickly, there are several remedies you can try to get rid of them, including:
- Redness-reducing eye drops
- Cold compress
- Omega-3 fatty acids
Each of these remedies has its benefits and can help you get rid of stoned eyes fast.
Let’s take a closer look at how they work.
Eye drops designed to reduce redness contain active ingredients like tetrahydrozoline hydrochloride, which help constrict dilated blood vessels in the eye, providing fast relief from redness.
These eye drops can be a quick and easy solution for weed eyes, but it’s important to use them responsibly to avoid potential side effects. Overusing eye drops that reduce redness can cause increased dryness, irritation and even more redness due to rebound effect.
If you choose to use these eye drops, be sure to follow the instructions on the label and consult with a healthcare professional if you have any concerns.
Cold Compresses and Caffeine
Another effective remedy for weed eyes is applying a cold compress or ice pack to your eyes. The cold temperature helps constrict blood vessels, reducing redness and swelling. You can use a store-bought cold compress, or simply wrap ice in a clean cloth and gently press it against your eyes for a few minutes.
Caffeine can also help alleviate weed eyes by shrinking blood vessels in the eyes. Drinking a cup of coffee or tea, or placing cooled tea bags over your eyes, can help reduce redness and discomfort. Just be sure not to overdo it with caffeine, as excessive intake can lead to other side effects.
Hydration and Omega-3 Fatty Acids
Staying hydrated is essential for maintaining overall eye health and can help prevent and get rid of stoned eyes. Here are some tips to keep your eyes hydrated.
- Drink plenty of water before, during and after consuming cannabis to keep your eyes moist and avoid dryness.
- Use lubricating eye drops to provide additional moisture to your eyes.
- Avoid excessive caffeine and alcohol consumption, as they can both contribute to dehydration that causes eye’s blood vessels to expand.
- Eat a balanced diet rich in fruits and vegetables, as they contain water and nutrients that promote eye health.
Consuming omega-3 fatty acids, commonly found in fish oil supplements and fatty fish, can also help with weed eyes. These fatty acids reduce inflammation and improve blood flow to the eyes, which can help reduce redness caused by weed. Including omega-3s in your diet can not only alleviate weed eyes, but also contribute to overall eye health.
Can Frequent Marijuana Use Lead To Chronic Red Eyes?
If you’re smoking cannabis flower all day every day, you may find that your eyes stay consistently dry and red.
That said, there isn’t any research that indicates you’ll have chronic red eyes if you frequently smoke weed or consume cannabis edibles.
If you do consume marijuana frequently, it’s important to be aware of how weed works in the body and what you can do to reduce some of the unwanted effects of marijuana use, including high eyes and other side effects.
Keep in mind that THC is what causes eyes to turn red. While there isn’t much research to support it, you might consider balancing your THC intake with CBD to reduce some of the side effects of marijuana.
Research shows CBD may counter some of the negative effects of THC consumption, which can be beneficial to those who use marijuana frequently.
In conclusion, weed eyes are a common side effect of cannabis consumption. They’re caused by the way THC interacts with the body. The decrease in blood pressure THC causes leads to the dilation of ocular capillaries, which causes eyes to become bloodshot and turn red.
While generally harmless, it’s essential to be aware of what causes red eyes if you’re a frequent cannabis consumer. Knowing how to reduce the appearance of your high eyes when high is also critical if you want to keep your cannabis consumption on the down low.
If you don’t want anyone you run into to know you’ve been smoking marijuana, quick remedies to get rid of stoned eyes fast include cold water, eye drops like artificial tears, cold compresses, consuming caffeine (but not too much), staying hydrated, placing tea bags on the eyes and consuming fish oil.
While you can’t prevent red eyes completely, you can help alleviate the telltale signs of your marijuana use by doing what you can to reduce just how bloodshot your eyes become.
By doing your best to maintain overall eye health, staying informed of what causes eyes to turn red and consuming cannabis responsibly, you can bypass a bit of the severity of the bloodshot stoned eyes that are a natural reaction in the body when consuming THC.
