Red eyes are frequently the most obvious symptom that someone has consumed weed, however, each cannabis consumer’s encounter with the plant is different. Cannabis consumption typically results in red eyes that last one to two hours, but in certain cases, they can persist for as long as three or four hours.

It happens to some people at all times they consume cannabis, and it might happen to others only sometimes. The variations in cannabis varieties and variations in the human body’s chemistry may be the cause of this. Know more about weed delivery in north york

Nonetheless, red eyes are rarely a cause for concern.

Reasons for Cannabis-Related Red Eyes:

Blood vessel health and blood pressure are the key factors. Tetrahydrocannabinol makes up one of cannabis’ primary active ingredients (THC).The chemical that makes up marijuana enters through the bloodstream and reacts with the body’s endocannabinoid system (ECS) upon consumption. Cannabinoids such as THC interact with receptors located throughout the body called the ECS. CB1 and CB2 receptors are the names given to these receptors.

THC molecules connect to CB1 receptors in the human brain and pupils, which results in the red-eye effect. The binding causes the blood vessels in the eye to dilate, which raises blood flow and lowers blood pressure. Blood vessels enlarge when blood pressure starts to drop. Although this occurrence happens throughout the body, the eye arteries are where it is most noticeable.

Difference between edible and smoking cannabis and does that make a difference in causing red eyes? 

THC binding to CB1 receptors causes red eyes in a variety of cannabis consumption modalities, including smoking, vaping, and eating edibles. Higher THC contents in strains increase the probability of developing red eyes. Smoking or vaping causes fast redness because THC enters the bloodstream and affects the eyes and brain. 

The key distinction between ingesting methods is how long it takes to manifest. THC ingestion from smoking or vaping causes red eyes immediately because it travels directly into the bloodstream and promptly reaches the blood vessels in the brain and eyes.

Smoke irritation can induce red eyes, however, this is not an important impact factor. 

When Will The Eye The Redness Go away ? 

Usually, red eyes produced by cannabis consumption will disappear one to two hours after initial stages. However, this will vary depending on how rapidly your body breaks down THC and the percentage of THC in the specific cannabis variety administered. The more THC in the cannabis, the more long-lasting the red eyes will persist. Some people get red eyes for three to four hours after using marijuana.

How do I Get Rid of Marijuana-Related Red Eyes? 

• Over-the-Counter Eye Drop

The most common way for reducing marijuana-induced red eyes is to apply over-the-counter (OTC) allergic drops for the eyes. 

• Caffeine

Consuming caffeine products can help to reduce the red eyes due to cannabis consumption, it is quite similar to eye drops as Caffeine promotes vasoconstriction, which reduces blood flow to the eyes and decreases redness. 

• Cold Compress

Coldness constricts the blood arteries in peripheral body parts (such as the eyes), limiting the circulation in these locations. When cold, the body naturally sends the majority of its blood to important organs like the human brain and the heart. 

• Put on sunglasses 

If you are unable to minimize the redness in your eyes, consider using sunglasses. The sunglasses will not remove the redness, but they will cover and hide it.
