Cannabis is the reason behind thousands of research papers, debates and discussions in the world today. Scientists are putting this herb under thorough tests and experiments to determine its properties and thereby its usage. So far, cannabis has helped in treating hundreds of diseases both in humans and other animals. Its therapeutic application has helped replace many harmful opioid painkillers in the market.
Doctors are treating patients suffering from various disorders like glaucoma, loss of appetite, insomnia, night vision problems, diabetes, chronic pain with cannabis. Many experiments and researches show that cannabis has helped in reducing the side effects of many deadly diseases like cancer or Crohn’s disease. Inspite of all these discoveries, some people try to hang a noose around this plant because of its psychoactive drug like effects.
How Marijuana Works?
A typical marijuana strain has two main compounds. A psychoactive compound called THC which is responsible for the high. A non-psychoactive compound called CBD which helps in treating a score of diseases due to its anti-oxidant, antiemetic and anti-inflammatory properties.
These compounds engage the endocannabinoid system of the body. The endocannabinoid system has two main receptors, CB1 and CB2. The CB1 receptor is present in abundance in the retina of the eyes. This receptor is also responsible for various body and mind sensations when the body is under cannabis influence. This helped scientists conclude that cannabinoids from the marijuana plant does have an effect on night vision.
The endocannabinoid system has a certain set of functions in the body. Though the scientists haven’t been able to pinpoint the exact function, they have made progress in the field of treatment. Most of the research concluded that the cannabinoid from cannabis plant alleviates the functioning of the endocannabinoid system.
Cannabis and Night Vision
Scientists conducted an experiment on tadpoles by treating them with cannabis. Tadpoles have very poor night vision and are unable to see in dark. They have retinal neurons known as retinal ganglion cells (RGCs) in their eyes. Cannabis treatment spiked the RGC activity and made these light-detecting cells more sensitive.
The cannabinoids have very similar effects on the human eye and therefore can help reduce impaired vision at night.
