Cannabis and Marijuana - Essay Example Although marijuana can be beneficial in the treatment of ailments like glaucoma, cancer, multiple sclerosis, AIDS and also chronic pain, researchers like Jacques-Joseph Moreau have discovered that marijuana has numerous harmful effects on the brain and the functions of the human central nervous system. Usage of cannabis hinders movement and memory in the brain. Chemicals in marijuana, especially THC and cannabinoids directly alter the emotions, memory and function of a user's brain and central nervous system. Marijuana changes to brain function and behavior by impinging on the central nervous and attaching its elements to the neurons in the brain, thereby interfering with the natural communication between the brain's neurons. This interference causes the nerves to alter their normal behavior. For instance, after using cannabis, a nerve that was supposed to enable a person to retrieve short-term memory, tends to act do the opposite, because of the cannabinoids receptors. Thus, if a person has to recall his recent activities, maybe his activities during the last 5 minutes ago, that person will have a lot of trouble accomplishing this, if he has taken a high dose of cannabis/marijuana. Cannabis contains about 400 chemicals, and about 60 of them are known to be cannabinoids, that are psychoactive compounds that are produced inside the human body and brain after cannabis is metabolized. "Cannabinoids is known to be the active ingredient in marijuana, and "the most psychoactive cannabinoids ch emical in marijuana that has the biggest impact on the brain is THC (tetrahydrocannibol). tetrahydrocannibol is the main active ingredient in marijuana because it affects the brain by binding to and activating specific receptors, known as cannabinoid receptors. "These receptors control memory, thought, concentration, time and depth, and coordinated movement." (J. Bartholomew, S. Holroyd, and T. M Heffernan 2010) When a person uses cannabis and his or her memory is affected, the short-term memory will be triggered first, as marijuana damages short-term memory as a result of the fact that the element tetrahydrocannibol interferes with the processing of information by an area of the brain called the hippocampus, which is responsible for the proper formation of memory. "One region of the brain that contains a lot of tetrahydrocannibol receptors is the hippocampus, which processes memory. Hippocampus is the part of the brain that is important for memory, learning, and the integration of sensory experiences with emotions and motivation. It also converts information into short-term memory. As a steroid, tetrahydrocannibol also acts on the hippocampus and inhibits memory retrieval. tetrahydrocannibol also alters the way in which sensory information is interpreted. When tetrahydrocannibol attaches to receptors in the hippocampus, it weakness the short-term memory, and damages the nerve cells by creat ing structural changes to the hippocampus region of the brain. When a user has a high dose of marijuana, new information does not register into their brain and this may be lost from memory and they are not able to retrieve new information for more than a few minutes. There is also a decrease in the activity of nerve cells." (M. Yucel, N.

Aboriginal Rights (Canada) Essay Example | Topics and Well Written Essays - 1250 words

Aboriginal Rights (Canada) - Essay Example They are separate entity rights in Canada that the aboriginal people have practiced and acclimatized to over time. Historically, the aboriginal rights merely protected the aboriginal people and their status in the society. However, the rights and freedoms accorded to the aboriginal people have taken a new shape in the recent times. The aboriginal people now enjoy more emphasized and cemented rights and freedoms, as do other people in Canada. This paper analyzes the aboriginal rights and freedoms from a political angle in order to determine their application in Canada. Past Application of Aboriginal Rights In the past, the aboriginal rights and privileges in Canada only applied within the borders of the country. Aboriginal politicians defended their countries especially when foreign countries infringed on the rights. Particularly, the aboriginal politicians complained to the international bodies like the United Nations over the imposition of the British crown rules on the aboriginal p eople (Panagos 407). The politicians argued that the aboriginal people were governed by the aboriginal laws hence the imposition of the British crown laws lacked meaningful ground for application. Many aboriginal groups however call upon the government to recognize the aboriginal laws. ... However, the government and colonial masters brought discriminatory pieces to the aboriginal rights hence the aboriginal people faced more discrimination even in the face of the new treaties. On such grounds, the aboriginal people in Canada are resistant to allow the government any point of disrespect to the aboriginal rights. Court Implementation and Application of the Aboriginal Rights In the existence of the aboriginal rights, the court has played a major role in solving disputes and aligning the aboriginal rights among the people. The courts have previously arbitrated the conflicts between the aboriginal politicians and the governmental agencies. According to Ray (400), in the recognition of the aboriginal rights by the government in 1982, the government did not define what these rights were. This brought a lot of confusion over the application and enjoyment of the rights. In a statement during the adoption of the aboriginal rights, the courts attained the power to determine the definition and jurisdiction of the aboriginal rights. In this sense, the courts would determine cases on grounds of whether the aboriginal rights applied to a case or not. The courts have also played a role in the aboriginal rights through the creation of the â€Å"sparrow test† in the case of the 1990 R v Sparrow decision. The case brought two factors into existence as regards the aboriginal rights (Collins 959). First, it defined the extent to which the aboriginal rights could apply and the pieces or parts that could be infringed by the government. The case also confirmed that the aboriginal rights were not absolute because the court, which
