Red Eyes from Using Cannabis
Example of what your eyes might look like before and after cannabis use

Marijuana use and squinted, puffy, bloodshot eyes go hand in hand, but why? What is it about smoking marijuana that makes you look like you got less than an hour of sleep last night, and what can you do to get your eyes looking normal again?

Getting your Ohio Marijuana Card means you have legal access marijuana products at dispensaries all over the Buckeye State. It also means that you may end up having even more trouble with red eyes. Fortunately, is here to help.

How Does the Green Make You Red?

Before we jump into how you can get rid of your red eyes, let's discuss why this happens in the first place. Are red eyes a reaction to CBD, THC, or both? If I eat an edible instead of smoking marijuana, will my eyes still look like I've been staring at the sun without sunglasses for a few hours? Let's find out!

While bloodshot eyes are a common response to marijuana use for many, there are two primary reasons that marijuana use results in reddened eyes.

The likeliest explanation happens also to be the reason cannabis is such an effective treatment for glaucoma: THC lowers blood pressure, and as a result causes blood vessels and capillaries to dilate. Some of these dilated capillaries happen to be in your eyes, which are known as ocular capillaries. As THC enters your system, your ocular capillaries dilate, allowing for increased blood flow, and thereby making your eyes appear to have a reddish hue.

You might think that if you decide to eat an edible instead of smoking marijuana that you can avoid your eyes reddening, but that's not necessarily the case. It is the cannabinoids themselves that make your eyes red, not the method of consumption. No matter how you get THC into your system, if the dosage is sufficient, you can expect your beautiful white eyes to become redder than a baboon's behind very soon.

Another, less common reason for red eyes resulting from cannabis use is the possibility of an allergy or irritation to cannabis or smoke; however, in these cases, the result of reddening eyes is not specific to cannabis and would likely be a universal reaction to any type of smoke or irritant that touches your eyes.

Say Bye-bye to Red Marijuana Eyes

While red eyes from cannabis use is harmless, many patients understandably don't want to broadcast their marijuana use to everyone they come face-to-face with.

So your eyes are red, and you don't know what to do? Here are a few tips and tricks to make your eyes as clear as a freshly cleaned window:

Opt for low or non-THC strains: Using strains that are high in CBD and CBN will be ideal for patients looking to avoid red eyes altogether. Any of your friendly-neighborhood dispensaries should be able to help identify the right strain to unstrain your eyes.

Wait it out: With time, your eyes will eventually transition from red back to white.

Plan your medication sessions at home: the reddening of your eyes from cannabis use is not harmful, and if you stay in the comfort of your own home you won't have to worry about what others may think.

Try Some Marijuana Red-Eye Pride

And again, it is important to remember that your eyes turning red after cannabis use is not dangerous, and for glaucoma patients the mechanisms that create a reddening of eyes is actually medically beneficial! Now that you are a legal medical marijuana patient in Ohio, don't be afraid to wear those red eyes as a badge of pride - red eyes mean that you are experiencing the amazing relief of medical cannabis!

And always remember, do not drive while under the influence of cannabis. Although you may feel comfortable and confident driving around while under the influence of THC, ultimately it is a major risk for not only you, but other drivers on the road. Plan your medication sessions out, and be smart when driving after medicating.
