Red eyes are a giveaway sign that someone has smoked marijuana. Also known as weed or cannabis, marijuana is a collection of dried leaves from the cannabis plant.
Smoking weed can induce several symptoms, like euphoria for some, while others might experience Anxiety or paranoia.
The onset of red eyes after smoking weed can trigger a panic-induced internet search – ‘Why does weed make your eyes red?’ or ‘How to get rid of red eyes from weed?’.
This article will discuss why red eyes from weed occur and how to get rid of them.
Why Does Weed Make Your Eyes Red
Tetrahydrocannabinol (THC) is the main psychoactive ingredient in marijuana that is responsible for turning eyes red.
As per research, marijuana can lower blood pressure in both men and women and induce a feeling of relaxation.
Lower blood pressure can dilate the blood vessels throughout the body, including the eyes, which results in an increase in blood flow. This process is medically known as vasodilation.
A higher amount of blood flow to the blood vessels in the white area can cause them to appear red or bloodshot, thus resulting in red eyes.
Marijuana is also sometimes prescribed to Glaucoma patients as it can lower blood pressure in the eye. However, such treatment of Glaucoma is not warranted or recommended.

Other Health Implications of Weed
Apart from red eyes, smoking weed can have several health implications, like the risk of heart disease or dry eyes. Let us discuss them in detail.
Dry Eyes
In addition to redness, marijuana can also lead to another eye-related issue: dry eyes. THC can reduce tear production, causing dryness and discomfort in the eyes.
If you experience this, using lubricating eye drops may help relieve the dryness.
Light Sensitivity (Photophobia)
Some users may become more sensitive to light after consuming cannabis. This can make your eyes feel more uncomfortable and painful when exposed to light.
Wearing sunglasses or seeking shade can provide relief.
Eye Pressure

Heart Disease
Marijuana use may increase the risk of heart disease due to THC-induced Tachycardia, raising heart rate and affecting blood pressure.
Marijuana can increase the risk of stroke and heart attack.

Limit THC Dosage
