Hemp is probably the most popular and frequently used drug in the world, which is illegal in most countries of the world. It has become so widespread that people do not even hesitate to smoke it in public places. It is an ancient medicine that has been used throughout history for medical and magical purposes. Over time, many myths have formed around this plant.
Memory loss - Laboratory tests have shown that hemp impairs the work of short-term memory, but only for that period while a person is under its influence. A person who uses cannabis can easily remember things that he knew before. Problems can arise only if he decides to begin to learn something new. There is no scientific evidence that cannabis has a long-term and permanent impact on a person's memory when he is not affected by it.
Smoking weed with the help of marijuana vaporizer (Vapingdaily.com gives more details), even, in the long run, is not harmful to health "(British medical journal The Lancet). Of course, there is no scientific consensus regarding the use of cannabis, and, of course, there is no scientific evidence that its rare use is dangerous to health.
A lot of people believe that dry herb vaporizer use leads to increased aggression and violence, which cause criminal behavior. In fact, the opposite is true. Research in this area shows that those who use cannabis are less prone to commit crimes because cannabis reduces aggressiveness. However, in most countries, the use of marijuana is illegal, and the people who keep it are considered criminals.
Hemp does not cause any deep changes in human mental abilities. It is true that after using it, some people may develop a sense of fear, panic, and paranoia. However, this all passes quickly and, of course, is not always present. It is possible that a person who consumes a large amount of any narcotic drug will have toxic psychosis, but this, again, is not peculiar only to hemp, and it is extremely rare in the case of it.
Regular use of herbal vaporizer negatively affects the cells of the retina. This result was achieved by scientists from the French University Pole Hospitalo-Universitaire de Psychiatrie du Grand Nancy under the guidance of Dr. Vincent Laprevo and published their findings in the journal JAMA Ophthalmology.
For the experiment, participants were selected 18-35 years old, which were divided into two groups: 52 people who used marijuana at least seven times a week during the last month, and 24 people who never smoked it.
Initially, none of the participants noted vision problems. However, a study of the retina showed that those who smoked herb vaporizer transmitted information from the retina to the brain more slowly.
It is not yet clear whether this is a permanent effect, or if it disappears with time, after the cessation of marijuana use.
Using marijuana helps to see better in the dark. This is evidenced by data from scientists from the Montreal Neurological Institute in Canada, reports the BBC. Researchers studied the mechanisms of cannabinoid influence on the eyes of the larvae of African clawed frogs. At first, scientists introduced synthetic cannabinoids to the scorch tape, and then, using microelectrodes, observed how the cells of the retina, the components of the optic nerve, reacted to light.
It turned out that cannabinoids made the cells more sensitive - they responded faster to both bright and faint light. To understand whether this had an effect on tadpole vision, scientists placed them in a transparent dish and studied their reaction to the dark points that tadpoles usually take to be predators. It turned out that under normal lighting there was no difference in the reaction of ordinary subjects and those who were injected with the drug. With poor lighting, tadpoles, under the influence of cannabinoids, avoided much more dark spots - their vision in the dark became noticeably better.
It is not yet known whether the substance also affects humans, but scientists have previously recorded information that cannabis helps residents of certain countries to see well in the dark. Researchers suggest that the results of the discovery may help in the treatment of diseases such as retinal dystrophy and glaucoma.
In general, mankind has used cannabis for medical purposes for more than 4,800 years - in China, Ancient Greece, and Persia.
Marijuana was prescribed as a painkiller for insomnia and disorders of the digestive tract.
Cannabis, as a medicine, received the greatest popularity and spread in the world in the 19th century precisely as a painkiller - right up to the invention of aspirin.
In the United States, cannabis was outlawed in 1937. The main component of marijuana, affecting the centers of the brain, is tetrahydrocannabinol (THC) - a chemical compound that generates feelings of euphoria and high.
The pharmaceutical industry produces Marinol (dronabinol) - this medicine is prescribed (in capsule form) and serves as an artificial variation of THC.
This drug inhibits, in particular, the emetic effect that occurs in cancer patients after chemotherapy, and prevents weight loss of people with AIDS - the syndrome of acquired human immunodeficiency.
As for the adverse effects of glaucoma, this disease leads to an increase in eye pressure. As a result, loss of vision may occur - the patient will become blind. Smoking marijuana - lowers pressure in the eyeball.
Doctors, in principle, can prescribe other drugs for the treatment of glaucoma, but the trouble is that as time goes on, they are able to lose their healing effect. Researchers are currently trying to develop new pain suppressants based on cannabis. THC may, in particular, work in the treatment of cancer as a painkiller, such as codeine, for example. For the same role, hemp is quite suitable for patients who have multiple sclerosis. And although doctors and patients propose to give legal status to marijuana, the US federal authorities are strongly opposed. On the other hand, marijuana has a side effect. Due to smoking weed, memory disorders, loss of coordination, hallucinations occur. Inhaling marijuana, a smoker increases the risk of cancer. There is also a fourfold risk of a heart attack in the first hour after smoking. However, marijuana can be bought by prescription in pharmacies in the ten, and even more, the American states.
However, federal agencies are closely monitoring the activities of medical authorities and doctors prescribing marijuana to patients.
