Red Eyes From Edibles? Why It Happens, And How You Can Avoid It

Do Your Eyes Get Red From Edibles?

Some people who aren’t familiar with how marijuana works often associate red eyes with smoke irritation.

However, this is a common misconception, as marijuana makes your eyes red for the same reason it is used to treat glaucoma. This physiological mechanism is known as vasodilation and it can also happen if you take edibles.

Do your eyes get red from edibles? Edibles, just like topicals and tinctures, contain THC, which has the potential to cause your eyes to become red because of vasodilation.

In this short read, you will learn why your eyes get red from taking marijuana and edibles and how to get rid of it.

The Reason Your Eyes Turn Red

Red eyes are most commonly known as bloodshot. This is the classic giveaway for people who consumed cannabis like edibles with a very high amount of THC.

For some people, their eyes turn red immediately after they consume cannabis.

However, for seasoned cannabis users, red eyes will always depend on the quality or quantity that they are consuming.

The primary reason why your eyes turn red after you consume cannabis or any edible is the same reason why cannabis is an excellent treatment for people with glaucoma.

THC lowers blood pressure, which causes blood vessels and capillaries to dilate.

When your ocular capillaries dilate, blood flow is increased to the eyes, which reduces intraocular pressure.

Increased blood flow can cause the eyes to turn red, and the decrease in the pressure is the exact effect that benefits glaucoma patients.

This can also happen with some end products of cannabis, like edibles.

The smoke is not what makes your eyes red; rather, it is the cannabinoids.

Getting Rid of Red Eyes From Edibles

If you happen to develop red eyes after taking some edibles, you do not have to worry, as it is harmless.

However, if you do not want to have red eyes, there are few things you can do to minimize and reduce the redness.

Carry Eye Drops

Plenty of products and brands offer eye drops formulated to reduce your eyes’ redness. If red eyes bother you, make sure to carry them with you after you take some edibles.

Drink Water

Not only is drinking water necessary, but it should also increase your fluid intake and alleviate the dryness.

Ultimately, your red eyes will subside and do not pose harmful and adverse outcomes.


If you want to get red eyes completely, try not to consume high-CBD strains. Strains high in CBD, CBN, and CBG are good alternatives to reduce red eyes when you are consuming edibles and other cannabis products.

It is not a bad idea to have eye drops and wear sunglasses if you are outside.
