Cannabis can yield Delta-8 THC, a cannabinoid known for its milder psych activity. However, Why Does Delta 8 Cause Red Eyes? Its multiple uses aside, a number of its users have complained about getting bloodshot eyes—the well-known red eye syndrome that accompanies cannabinoids. Thus, knowledge of what causes this redness can help guide strategies for users to reduce or prevent it.
Vasodilation and Blood Vessel Expansion
Vasodilation is one of the main causes behind red eyes after taking Delta-8 THC. Cannabinoids like Delta 8 or others bind with the endocannabinoid system (ECS) in our human body to perform various biological processes, such as blood circulation. Delta-8 THC can stimulate relaxation and help cause those blood vessels, including the ones in our eyes, to dilate.
Lowering Intraocular Pressure
Decreased intraocular pressure (IOP) also contributes to eye redness. Moreover, it is reported to reduce IOP (intraocular pressure)—a major reason why people with glaucoma find comfort when they take delta-8 THC. But a reduction in pressure can cause red-eye-like symptoms. This decrease in symptoms causes the small blood vessels in your eyes to appear more persistent, resulting in a red or bleary appearance.
Dehydration and Dry Eyes
Since delta-8 THC dehydrates most people, it could also be the cause of eye redness. The lack of hydration is severe for all body parts, and it also affects the eyes. Dehydration reduces tear production in the body, leading to dry eyes. Redness results from irritation, and dry eyes are susceptible to irritation.
Adverse Effects and Sensitivities
The redness in your eyes could be caused by an intolerance or an allergic reaction to Delta 8THC or other compounds in a product. It is common for redness in the eyes to occur when your skin experiences allergic reactions and becomes irritated, which can further inflame the surrounding areas of the eye.
Environmental Factors
In addition to this, environmental factors can also further aggravate red eyes when using Delta-8 THC. For example, if a user is in an environment that is too dry or filled with smoke and dust, their eyes might already be irritated. This may become more pronounced because of the delta-8 THC, which can dry out your eyes.
When it comes to red eyes with the use of Delta 8 THC, you might find yourself asking, Why Does Delta 8 Cause Red Eyes? The answer lies in a few possible causes: you could be experiencing vasodilation, which is a bit iffy as we said, low intraocular pressure, dehydration leading to bloodshot eyes, or possibly even some kind of allergic reaction.
