Pineapple diesel making your eyes bloodshot? If you are among the 158.8 million people worldwide who use marijuana (that’s 3.8% of the world’s population!), then you know that red eyes are the most classic, telltale giveaway that you’ve been smoking.

Despite the legalization and widespread use of cannabis for recreational and medical purposes, smoking is still considered a taboo in some communities. So, if you’re not comfortable letting your bloodshot eyes broadcast to the world what you’ve been doing behind closed doors, here are a few tips on how to reduce the redness. But first, we’re going to take a moment to explore the science behind this common reaction.

Why does cannabis make your eyes red?
Many people assume that their eyes turn red when they smoke because of an acute reaction to the smoke itself – like when your eyes become irritated around a smoky campfire. They are surprised to learn that the exhaled smoke has nothing to do with it. In fact, some people experience red eyes while consuming edibles.

How does that work? Well, it’s not the smoke but the cannabinoids that are causing the redness. The THC present in marijuana lowers your blood pressure, which consequently dilates your blood vessels and capillaries. As the ocular capillaries dilate, blood flow to the eyes increases and intraocular pressure is reduced. It’s this process that makes your eyes become bloodshot.

How do you reduce the redness after consuming cannabis?
First, know that the red-eye reaction from marijuana is totally harmless. In fact, the dilation and increased blood flow can actually be beneficial to your eye health. That is why cannabis is sometimes used as a treatment for glaucoma. Regardless, it may not be a marijuana side effect you particularly enjoy. So, here are a few ways to get rid of eye redness:

• Opt for strains with low THC. Instead, you may want to lean more towards strains high in CBD, or cannabidiol.
• Keep some eye drops on hand. There are some brands specifically formulated to reduce redness.
• Drink plenty of water. Staying hydrated will help with any dryness you are experiencing as well.

Ultimately, don’t let a little red-eye ruin your relaxing smoke sesh.
