Why Does Weed Make Your Eyes Red or Bloodshot?

Many weed smokers associate the red eyes with the smoke from a joint. You will usually hear people say that you won’t develop bloodshot eyes if you take edibles, flowers, or concentrates. However, this is not true.

According to the science behind marijuana’s cannabinoids, red eyes are caused by the dilation of the ocular capillaries. In addition, the blood vessels and capillaries in the body undergo dilation since the cannabinoids in weed, specifically THC, lower your blood pressure.

The dilation process of the ocular capillaries begins with the ingestion of marijuana through any form; smoking a joint, eating edibles, etc. The cannabinoids in the weed contact cannabinoid receptors found in various places in your body, especially the eyes.

The interaction of the cannabinoids with the receptors causes results in the dilation of blood vessels which insights an increase in blood flow. This counterattack from the heart causes an increase in blood flow to the dilated areas, resulting in a decrease in blood pressure. Conversely, excessive blood flow to the eyes causes them to turn red and induce dizziness due to low blood pressure.

The power of the Delta-9-tetrahydrocannabinol (THC) to reduce ocular blood pressure has been able to open doors for treating glaucoma. Glaucoma encompasses various diseases that damage the health of your eyes and your ability to have good vision.

Moreover, research from Indiana University has showcased how cannabidiol (CBD) in marijuana can worsen by increasing the blood pressure in the eye.

As it stands today, weed isn’t considered a treatment for glaucoma but is regarded as a pain reliever for the condition. The effect usually lasts for a few hours before it subsides, leaving the disease in the same state as it was before. However, studies show that cannabis contains neuroprotective and antioxidant benefits that promote eye health and improve vision despite inconclusive evidence.

What other factors that lead to red or bloodshot eyes?

Apart from the dilation of the ocular capillaries, other causes of red eyes can range from allergies and other underlying bodily issues or exterior influences. The potency, quality, and quantity of the weed taken is also a huge factor in bloodshot eyes.

Some weed variants and strains can cause an easy onset of red eyes five to ten minutes after ingesting them. Early-onset of bloodshot eyes may indicate that the weed is highly concentrated with THC compared to other strains. It may also show you that you have taken a little bit too much if it is accompanied by excessive dizziness and sluggishness.
