You’ve just taken a huge bong rip or smoked a fat blunt with some friends, but oh no, now your eyes have gone red. Yeah, bloodshot eyes is one of the main side effects you will get from smoking weed, and it happens to pretty much everybody.

Of course, you may not want to advertise that you’re fried as a KFC drumstick. Maybe you have to go work or a family dinner. How to get rid of red eyes from weed is an age-old question that every stoner has been contemplating since the beginning of time.

Let’s talk about why weed makes your eyes red and how to get rid of it too!

Why Do You Get Red Eyes When Smoking Weed?

What is very interesting about this whole thing is that in theory, your eyes going red is not at all a bad thing.

The reason why your eyes go red when you smoke or ingest pot is because of the THC, that awesome stuff that gets you high as a kite.

THC Effect On Blood Pressure

THC will actually decrease your blood pressure, which means that blood vessels will expand and allow more blood to flow throughout the body.

Well, you have blood vessels in your eyes, and yes, they also expand, and because they expand and have more blood in them, they look visibly red.

Now, some people only get slightly red eyed while others look like frightening demons, but this is why it happens. Some believe that it’s the smoke touching the eyes which makes the eyes red, but this is simply not true.

Ok, well, if you get a huge cloud of smoke in your eyes, they might get all dry and irritated, and a bit red, but this is not what is really going on in the grand scheme of things.

Do Your Eyes Get Red From Edibles?

Yes they do. If it were literally because of the smoke, then ingesting weed edibles wouldn’t make your eyes go red, but ask anybody who eats edibles, and they’ll tell you that eyes go just as bloodshot as when marijuana is smoked, if not more so.

Side Note

On an interesting side note, the expansion of the blood vessels and lowering of blood pressure caused by pot is the exact reason why it makes such a good medicine for people who suffer from glaucoma, an eye disease which can lead to loss of vision and blindness.

That’s right folks, the same reason why your eyes go red from smoking pot is why it can stop people with glaucoma from going blind!

4 Best Ways To Get Rid Of Red Eye From Weed

Alright, so to be honest, the only way to get rid of red eyes from smoking weed is to use eye drops, and those don’t even always do the trick 100%.

Some people will tell you to wash out your eyes, to drink water, or other nonsense like that, but none of it really works, at all.


The one and only solution is to use eyedrops. Normal eye drops contain something called tetryzoline, which helps to constrict blood vessels, in this case those in the eyes.

It’s actually meant for people who suffer from allergies, but works great for pot heads too.


Now, what may work some of the time, depending on your metabolism and your body, is to drink caffeine, or anything else which causes heightened blood pressure and the constriction of blood vessels.

Drinking a couple cups of coffee might just do the trick, but it’s a hit and miss kind of thing, and often the only thing you’ll accomplish by doing this is a huge energy boost, shaky hands, and the need to go to the toilet every half hour.

So, the moral of the story here is that if you want to smoke weed, and don’t want people to see your red demon eyes, get some over the counter eye drops.

Drink Water

Now, to be clear, drinking water is not a sure fix solution but it’s something that you can do in addition to say eye drops. Red eye can also be caused by being dehydrated, so a few glasses of water can certainly help. Drinking water is good for your body, and most important will help combat dry mouth from smoking.

Smoke Lower THC Strains

Lower THC you say? yes, we know this might not be a favorable option (which is why we didn’t put it first), but if red eye is causing you issues then consider smoking a lower THC strain. THC is the main culprit for causing red eyes, and you can still have a good smoking experience without smoking high THC strains.

Wear Sunglasses

When all else fails, put on your shades and go cool mode with some sunglasses? This is really dependant on the time of the year, you obviously don’t want to be walking round in shades if it’s snowing or raining outside as it will look a bit odd. This is of course a temporary solution as wearing sunglasses will obviously not outright fix the issue, but mask it while you are outside.


Alright, so as you can see, it’s not like your eyes going red is anything bad really. Sure, it might not be best for appearances, but it certainly is not harmful or fatal in any way, shape, or form. However, if you don’t want people to know that you’re flying up in the clouds, you might want to get some eye drops to get rid of red eyes from weed.

Other than that, there is really no other good solution. Of course, the more you smoke over time, the less this happens, but you have to be come a real professional stoner to stop your eyes from getting red, and even then it will still happen to most. It’s just something you are going to have to deal with.
