Red eyes are usually a sign of fatigue, allergy, or infection. But the redness of the eyes as a result of smoking weed isn’t because of any exhaustion, illness, or irritation. Instead, it’s the body’s natural reaction to the psychoactive compound of marijuana – THC.
After the effects of THC begin to normalize, your heart rate will return to normal, and your blood pressure will decrease. Afterward, CB1 receptors signal the body to lower blood pressure throughout, this includes your eyes’ ‘intraocular’ pressure. When that occurs, your blood vessels will expand, increasing blood flow to the eyes. That’s when your eyes begin to look bloodshot and red.
You can get red and bloodshot eyes from eye conditions such as digital eye strain, wearing contacts, dry eyes, and not getting sufficient sleep. Digital eye strain is also called computer vision syndrome. On average, an individual spends around seven hours in front of their computer or tablet every day, which can result in headaches, blurriness, and eye strain. Make sure you look at your computer from a distance and have the proper posture to minimize the chances of straining your eyes.
Does CBD Make Your Eyes Dry?
Although weed-triggered redness of the eyes is pretty much harmless, it’s not something that conventional society will appreciate. It gives off a wrong impression from where misconstrued assumptions and judgments will form. So, if you’re susceptible to eye inflammation after smoking weed, consider staying hydrated to avoid the possibility of heavy dry eyes from THC intake.Have a good eye drop at hand. Also, you can also change the strain you’re taking if it proves too much to handle.
You probably know that one of marijuana’s prominent effects is causing red eyes, however, CBD does not share that feature. CBD is a natural compound found in marijuana and hemp plants. This cannabinoid interacts with the endocannabinoid system (ECS) of the body. The ECS plays an integral role in your body’s homeostasis. That means it plays a part in keeping an overall internal balance for many bodily functions. These includes memory, mood, digestion, appetite, stress, muscle formation, sleep, and so on.
As mentioned earlier, THC interacts with the endocannabinoid receptors in the body directly. Meanwhile, CBD doesn’t interact with the same receptors but instead triggers the ECS to keep more of its natural cannabinoids. As a matter of fact, CBD has proven to counteract the effects of THC since it hinders THC from interacting with receptors directly.
Sometimes bloodshot eyes can be a sign of a significant problem such as an eye injury or eye infection. It can also be uveitis, corneal ulcer, or glaucoma. A person can also have red eyes from eye surgeries such as LASIK. If you don’t know what has caused your eyes to become red or are experiencing some discomfort, you should consider contacting an eye doctor.
It’s also possible to be allergic to specific terpenes, flavonoids, or other compounds in hemp flower. In the end, you might just be the kind of person whose eyes are sensitive to smoke.
If THC makes your eyes red because it is a vasodilator, does CBD do the same thing? To answer this question, let’s take a look at research into the cardiovascular effects of CBD and note the anecdotal evidence on subject.
THC is such a potent ocular vasodilator that it’s used for glaucoma to this day, but CBD doesn’t share these qualities. If you have any lingering questions about CBD making your eyes red, contact us , and check out our other guides in the Shared Secrets blog .
1. Does CBD affect your eyes?
Why does Cannabis sativa make your eyes red, though? Many cannabis smokers would guess that weed smoke gets in your eyes and makes them irritated. If that’s the case, however, why don’t cigarettes or campfires do the same thing?
It’s worth remembering, however, that only one study has shown CBD might lead to an increase in intraocular pressure in patients who already have glaucoma. These results haven’t been corroborated by followup research.
There’s no scientific evidence that CBD might help with cataracts. The development of cataracts appears to be related to oxidative stress , and the impact of CBD on oxidative stress and inflammation has been well-researched . It’s unclear if CBD helps with the same types of oxidative stress involved in cataracts, however.
THC use has become a lot more prevalent over the last few years. That doesn’t necessarily mean, however, you want to be identified as a stoner just because you use CBD.
The greater the concentration of THC in a cannabis product, the stronger the effects and the redder your eyes become.
It generally takes about five to ten minutes for users’ heart rates to return to normal and for blood pressure to begin to decrease. As the blood pressure lowers, the blood vessels and capillaries dilate, including the ocular capillaries . The dilation of ocular capillaries causes increased blood flow to the eyes, which results in your eyes turning red and also reduces intraocular pressure.
Tetrahydrocannabinol (THC), the most common cannabinoid in the plant, is responsible for the intoxication associated with smoking cannabis. The greater the concentration of THC in a cannabis product, the stronger the effects and the redder your eyes become.
The redder the better?
For weed novices, the onset of bloodshot eyes could cause a panic-induced internet search asking “ can smoking weed damage your eyes? ” Thankfully, as those who regularly consume cannabis can tell new users, there are no serious health risks associated with your sudden red-eyed circumstance. You’re probably not experiencing an allergic reaction or some bigger complication. Some might poke fun or chastise you for sporting your so-called “ weed eyes ” in public, but otherwise, it’s a completely natural occurrence that transpires after smoking cannabis.
Other than being a dead giveaway that you’ve recently consumed cannabis, you have no reason to be concerned about the redness of your eyes. Cannabis-induced eye redness will typically only last a few hours and can easily resolve if you have the right tools at your disposal.
So, red eyes can act as a sign that your cannabis has a high cannabinoid content (i.e., it’s potent). In other words, if your eyes are noticeably bloodshot after consumption, there’s a good chance you’ve landed yourself some highly potent weed.
Among the most common effects of marijuana use (and telltale signs you’ve recently partaken) is red, bloodshot eyes. It’s to be expected, sure, but that doesn’t answer the mysterious question pondered by generations of stoners: why does weed make your eyes red?
