Smoking or using marijuana is renowned for one of its most telling side effects: red eyes. Most users know about this, symptoms and many are fine with it, though if you are confused about why it happens you should definitely read up on it – starting with this article, which will outline the medical justifications as well as ways to hide your red eyes in a public setting.

Red eyes usually aren’t anything to worry about, although they certainly are considered unhealthy by medical professionals in many respects, mainly because they are associated with conditions like conjunctivitis and the flu. However, when it comes to cannabis, there are published studies that claim red eyes aren’t negative at all, in fact, quite the opposite.

Scientists have discovered that some cannabinoids have a positive impact on blood pressure, meaning that they can actually lower it. This is connected to red eyes because when blood pressure is lowered in the body, the blood vessels dilate, and blood is able to flow through veins much more effectively. Essentially, when the blood pressure is lowered,

more blood gets to the little arteries in our eyeballs and so they turn red or pink.

There are a myriad of things that can influence eye reddening and the likeliness of it occurring, including your genetics, your tolerance, the kind of cannabis you’re actually smoking, and how hydrated you are. For example, some people’s DNA simply dictates that they can smoke a crazy amount and they just won’t ever get red eyes.

If you live somewhere weed is frowned upon, or you just don’t want people to know you’re high, there are a few things you can do to conceal red eyes – which is one of the biggest tells that a person is stoned. One piece of advice I have is to carry sunglasses, or even reading glasses, with you as they can really help to hide your eyes. Eye-drops are also a decent option and can be extremely effective as they lubricate your eyeballs.

Overall, red eyes can be an irritating side effect of smoking weed – but suffering from them isn’t the end of the world. At the end of the day, people are probably too busy to notice anyway. Furthermore, it’s pretty ridiculous that smokers should be made to feel like they need to hide side effects in the first place – why should we have to camouflage the effects of simply smoking a plant? Anyways, happy smoking
