Why Marijuana Makes Your Eyes Red

Why Marijuana Makes Your Eyes Red

Red eyes or bloodshot eyes are a natural occurrence among Marijuana users. Red eyes are a common side effect and a telltale sign of marijuana usage. Scientifically, they are not a bother, and they pose no danger among cannabis users. For some individuals, it’s a common sign while others are less sensitive; it all depends on the quality and quantity of marijuana one uses.

Now, what is the main cause of red eyes among cannabis users?

Lower blood pressure and dilated capillaries

Dilation of blood vessels is the main reason for bloodshot eyes, and it’s also the main reason why marijuana is used to treat glaucoma. In summary, marijuana causes a decrease in blood pressure, and as a negative feedback mechanism by the body, ocular blood vessels dilate leading to increased blood flow to the eyes and a decline in intra-ocular pressure. The increased blood supply to the eyes leads to red eyes phenomenon among marijuana users; thus the name bloodshot eyes. Note that the decline in intra-ocular pressure benefits glaucoma patients. Also, the reddening of the eyes is as a result of the chemicals knowns as cannabinoids within the cannabis and not the smoke.

The intensity of redness of the eyes depends on the quantity and quality of THC consumed. Tetrahydrocannabinol (THC) is the most prevalent cannabinoid in weed. The higher the amounts of THC consumption the redder the eyes. Red eyes can also occur when consuming other foods if they contain cannabinoids.

With that said, it’s possible for someone to have an allergy towards cannabis or smoke. Just that for those with an allergy their eyes redden as a result of the smoke being emitted and not the cannabinoids.

Bloodshot volume varies from one person to another

If you are a keen observer, you may have noticed that marijuana effects vary among people i.e., for some, their eyes turn very red while in others they turn slightly or not at all. Science explains that this happens due to a myriad of reasons some of which include: sex, genetics, consumption frequency, and one’s health status. Also, if one has a higher incidence of using weed, with time (s)he becomes tolerant, thus he/she experiences little or no side effects of cannabis consumption.
