M. E. West, a pharmacologist at the University of the West Indies in Kingston, Jamaica, noticed that local fishermen who smoke cannabis or drink rum produced from the plant’s leaves and stems had an “unusual” ability to see in the dark. They could navigate their boats through coral reefs using this skill.You can find more information about cannabis edible here. He said that, “It was impossible to imagine that someone could navigate a boat in such hazardous surroundings without a compass or light.” However, he became convinced that the individual who took the cannabis rum extract had better night vision than he did and that a subjective experience was not to blame.” Looking to try something new?

Some crew members informed West that Moroccan fishermen and mountain people reported a similar boost after using hashish, so in 2002, another team of researchers traveled to the Rif Mountains in Morocco to learn more. They gave one volunteer with a manufactured cannabinoid and three others with hashish before employing a newly developed gadget to assess their night vision sensitivity before and after. They confirmed what previous studies had found: cannabis improved night sight in all three subjects tested.
Another research has found a cellular mechanism by which cannabis might enhance night vision, providing hard evidence for the claim. The findings, published in the open access journal eLife just recently, may be used to treat patients with degenerative eye diseases such as retinitis pigmentosa in the future.
Cannabis is thought to affect neurons in the brain. Because the retina is a direct extension of the central nervous system, comparing retinal functions in both cannabis users and non-users might provide insight into the drug’s effects on the brain, according to Laprevote and his colleagues.
The researchers examined whether cannabis affects retinal ganglion cells, which are cell types present in the retina. “We’re particularly interested in these ganglion cells because they function as brain cells,” added Laprevote.
The photoreceptors are tiny light-sensitive cells that line the back of the eye and help to convert light (visual stimulation) into a series of electrical pulses, called action potentials, in the brain. “Signals from the retina must travel to the visual brain in just the correct order for normal visual processing to take place,” Frishman said.
The researchers investigated the electrical and physiological response of retinal ganglion cells in 52 people: 28 regular cannabis users and 24 nonusers.
The researchers found that cannabis consumers had a slower reaction time than non-users. On average, marijuana users responded in 98.6 milliseconds, whereas control participants reacted in 88.4 milliseconds.
And What About Mushrooms?
There’s also a more appealing belief that psilocybin mushrooms can help you see better. The famous ethnobotanist, mystic, psychonaut, lecturer and author Terence McKenna even has an intriguing concept about human consciousness evolution based on this thinking, and everyone knows hallucinogenic mushrooms have sensory effects, especially on vision and hearing.
Colors are more vivid and have greater contrast. It’s true that you’ll notice halos around back-lit things, perspective distortion, and a glowing haze in the air, as well as moving surfaces that look to flow from one location to another, ripples, pulses, or anomalies, kaleidoscopic textures, color-changing objects, tracers, and other odd features that I recall as “special effects” of cataracts.
It all comes down to dosage, which is why vitamin companies are sprouting up (like mushrooms) that provide tiny homeopathic doses of these mind-altering chemicals. I think it’s comparable to wine in this regard. Wine may beautify your life if you have a sense of moderation; if you don’t, it might consume you alive. “There is nothing that cannot be hellish.”
Why Edibles Make Eyes Red?
Edibles cause the eyes to become red since THC, one of the components, is a vasodilator. The cannabinoids work with receptors in your body and your eyes. This causes blood pressure to drop and blood vessels and capillaries to expand, bringing increased blood flow to the region. This is why your eyes (or at least the white portion called the sclera) turn pink or red in color.
Eye redness is possible, but it doesn’t always occur after eating edibles. THC concentrations vary from product to product. As a result, eye redness does not always occur.
Another factor to consider is a person’s health status. Blood pressure, sex, genetics, and overall health are all examples of individual factors. Those with high blood pressure will require a higher concentration level of THC to achieve the desired blood pressure reduction in order for their eyes to turn red.
According to experts, smoking cannabis can harm the lungs. It’s also been shown that regular marijuana usage has a negative impact on the brain. However, while more study is needed on the possible beneficial and/or detrimental effects of marijuana on eyesight, we do know that it has several important impacts on the eye.
One of the most significant impacts is red eyes, which appear soon after smoking marijuana. THC (tetrahydrocannabinol) in marijuana causes blood pressure to fall, causing the vessels in the eyes to dilate and allowing more blood flow throughout the body. This results in increased blood flow throughout the body, causing the eyes’ arteries to expand, resulting in redness or hazy vision.
