Marijuana. That forbidden, annoying substance that most people are afraid to try, mostly because of what they might think if they did. Cannabis is a plant native to Mexico and South America, used for centuries by ancient Indian civilizations. There are three species of plant: Cannabis Sativa, tall and stemmed, Cannabis Indica, smaller and bushier, and Cannabis Ruderalis, found mainly in Russia and Eastern Europe (Armentano). This plant has historically been used for medical purposes such as decreasing nausea and vomiting, increasing appetite loss, chronic headaches, anxiety, and depression, among others. This drug, however, is considered very dangerous in most nations today because it is seen as the “gateway drug” to try harder and heavier drugs, and therefore governments have outlawed it. What most people don't know is that the human body has a system called the endocannabinoid system. Many may wonder, “Is this a real thing? How does it work?" and the answer is yes, it is a real thing and it works as follows. The endocannabinoid system is a central regulatory system that influences a wide range of biological processes. It is made up of a group of molecules known as cannabinoids and the receptors of the cannabinoids they bind to. There are two types of cannabinoid receptors, CB1 and CB2. These receptors are found in various parts of the body, but are most important in the brain and immune system and in the immune system, researchers have also identified cannabinoid receptors in a variety of other locations, including the peripheral nervous system, cardiovascular system, reproductive system, and gastrointestinal system… center of paper… and conditions, and as a recreational substance for people suffering from anxiety or depression. Regardless of whether you choose to use the drug, it will still have beneficial effects on the body. The government, however, has made the use of this drug illegal due to social fears and prejudices: the policies they have imposed on the use and possession of the drug violate human and civil rights, and this goes against their own constitutions . The first thing to do, before taking any action on the legalization of cannabis, is to educate all citizens, especially those who belong to the lowest social classes and have very limited information and education, so that they can know how the drug works, what effects it has about the body and how the government and public services violate the rights of civilians when carrying out any kind of tests and restrictions.
