In the mid-nineteenth century, pharmacologist M. E. West of the University of the West Indies in Kingston, Jamaica remarked that local fishermen who smoked marijuana or rum made from plant leaves and stems had an “unbelievable” ability to see in the dark, allowing them to navigate their boats through coral reefs. You can find more information here. He observed that “the use of cannabis, in the form of rum extract, appears to have some advantages over cannabis as it relates to night vision.” He observed that “the man who had been given the rum extract of cannabis had far better night vision than I had, and that a subjective experience was not responsible.” Looking to try something new?

Several crew members informed West that Moroccan fishermen and mountain people had similar benefits from smoking hashish, and in 2002, another research team traveled to Morocco’s Rif Mountains to investigate further. They gave one volunteer a manufactured cannabinoid and three others a preparation of hashish before measuring their night vision sensitivity using newly developed equipment. They discovered that cannabis increased night vision in all three of their test individuals, according to the results of previous studies.
There’s now concrete evidence to support the claim that cannabis improves night vision. The findings, which were made public in the open access journal eLife, could be used to help people with degenerative eye diseases like retinitis pigmentosa.
Cannabis is thought to impact synaptic transmission in the brain. Because the retina is a simple extension of the central nervous system, comparing retinal functions in both regular marijuana smokers and non-users might reveal additional insights into the drug’s effects on the brain, suggested Laprevote and his collaborators.
The researchers looked at whether cannabis affects retinal ganglion cells, which are cell types in the eye that function like brain cells. “We’re particularly interested in these ganglion cells because they behave like brain cells,” Laprevote added.
The rods and cones in the eye convert light (visual stimulation) into a series of electrical pulses, known as action potentials, in the brain. “Signals sent from the retina to the visual brain must be received at exactly the right moment for normal visual processing,” says Dr. Laura Frishman of the University of Houston College of Optometry, who was not part of this research.
To assess the retinal ganglion cell function after marijuana usage, researchers examined the electrical and physiological response of these cells in 52 persons: 28 long-term cannabis users and 24 nonusers.
Laprevote and his colleagues discovered that cannabis users have a delayed response time when compared to non-users. Marijuana users registered 98.6 milliseconds on average, versus 88.4 for the control group, according to their research.
And What About Mushrooms?
There’s also a more popular idea that psilocybin mushrooms can help with vision. Terence McKenna, the famous ethnobotanist, mystic, psychonaut, lecturer and writer, has a fascinating theory regarding human consciousness development based on this thinking, and everybody knows that hallucinogenic mushrooms have sensory effects, particularly with respect to sight and hearing.
Colors are more vivid and have greater contrast. It’s true that you may see halos around back-lit items, perspective distortion, and a sparkling fog in the air, as well as moving surfaces that appear to flow from one place to another, ripples, pulses or deformities, kaleidoscope textures, color-changing objects, tracers, and many other things that personally remind me of cataract “special effects.”
It’s all about the dose, so vitamin firms are popping up (like mushrooms) that sell tiny, homeopathic doses of these psychoactive chemicals. I believe wine can be compared to this. Wine may beautify your life — or it might pull you under depending on your attitude towards moderation. Just as with anything else. “There is nothing that cannot be hell.”
Why Edibles Make Eyes Red
Edibles’ red eyes are caused by one of the components, THC, being a vasodilator. The cannabinoids bind with receptors in your body and your eyes. This causes blood pressure to drop and blood vessels and capillaries to dilate or expand, bringing blood flow to the area. This is why your eyes (or at least the white part called the sclera) turn crimson in color.
It is not guaranteed that you will experience eye redness after consuming edibles. Every edible product has a distinct concentration of THC in it. Eye redness won’t always occur as a result of this.
Finally, a person’s physical health matters. Blood pressure, sex, genetics, and overall health are all examples of factors that influence individual health. People with high blood pressure will require a higher THC concentration in order for their blood pressure to fall sufficiently enough to induce eye redness.
Experts agree that smoking marijuana damages the lungs. The harmful impact of long-term, frequent marijuana use on the brain is well recognized. However, while additional research is needed regarding the potential beneficial and/or detrimental effects of marijuana on eyesight, we do know that it has a handful of important functions.
Red eyes are one of the most obvious effects after smoking marijuana. THC (tetrahydrocannabinol), the active chemical in marijuana, lowers blood pressure and dilates blood vessels, allowing for increased blood flow throughout the body. This Results in the eyes’ veins expanding, resulting in redness or bloodshot eyes.
