What Causes Red Eyes from Weed?

The primary reason behind red eyes after consuming cannabis is due to the presence of tetrahydrocannabinol (THC) the main psychoactive compound in marijuana. THC lowers blood pressure which causes the blood vessels and capillaries to dilate including those in your eyes. This dilation increases blood flow to the eyes making them appear red or bloodshot.

Its important to note that red eyes are not necessarily an indication of being high. Some people may experience red eyes even with low doses of THC while others may consume large amounts without any noticeable redness. Factors such as individual physiology tolerance and the specific strain of cannabis can all play a role in the severity of red eyes.

Methods to Get Rid of Red Eyes from Weed

Eye Drops

One of the most popular and effective ways to combat red eyes from weed is by using over-the-counter eye drops. Look for drops that contain tetrahydrozoline or naphazoline which are vasoconstrictors that help shrink the blood vessels in your eyes reducing redness.

Some popular brands include Visine Clear Eyes and Rohto. Be sure to follow the instructions on the packaging and avoid overusing eye drops as this can lead to rebound redness.

Stay Hydrated

Drinking plenty of water can help flush out toxins from your body and reduce inflammation in your eyes. Aim to drink at least 8 glasses of water per day and increase your intake if you feel dehydrated after consuming cannabis.

Cold Compress

Applying a cold compress or ice pack to your eyes can help constrict the blood vessels and reduce redness. Wrap a few ice cubes in a clean cloth or use a gel eye mask and apply it to your closed eyes for 10-15 minutes. Repeat as needed.

Adjust Your Environment

Harsh lighting and dry air can exacerbate red eyes. If possible dim the lights in your room or wear sunglasses to minimize light exposure. If youre in a dry environment consider using a humidifier to add moisture to the air which can help soothe irritated eyes.

Wait It Out

In most cases red eyes from weed will subside on their own within a few hours. If youre not in a rush to be somewhere simply wait it out and let your eyes return to their normal appearance naturally.

Choose Low-THC Strains

If you find that you are particularly prone to red eyes consider opting for cannabis strains with lower THC content. Strains high in cannabidiol (CBD) and low in THC may be less likely to cause severe red eyes.

Practice Good Eye Hygiene

Maintaining good eye hygiene can help prevent and alleviate red eyes. Be sure to remove any contact lenses before consuming cannabis and avoid rubbing your eyes as this can cause further irritation. If you wear makeup remove it before going to bed to prevent any debris from irritating your eyes overnight.
