Marijuana Influence on the Students Cognitive Abilities

June 29, 2018

The latest events in America demonstrate that more states are open to legalizing marijuana, which is a great sign for many people who really need it. However, there is also a theory that marijuana can influence the student’s cognitive abilities. Is that so? Let us find out.

The influence of Marijuana

There are many myths about marijuana and its usage. Marijuana kills brain cells. Prolonged use of marijuana causes persistent disruption of the structure and functions of the brain, leading to memory loss, cognitive impairment, personality disorders, and impaired ability to work.

The real fact is: none of the medical tests currently used to detect brain damage in humans has detected harm from marijuana, even with its long-term use in high doses. In one of the first studies, brain damage was reported in rhesus monkeys after six months of exposure to highly concentrated smoke from marijuana. In a recent, more thorough study, the researchers found no evidence of abnormalities in brain function in monkeys who were forced to daily inhale marijuana at doses equivalent to smoking 4-5 marijuana cigarettes a day. The statement that marijuana kills brain cells is based on a speculative message that appeared a quarter of a century ago, which has never been confirmed by scientific research.

Based on the current scientific evidence, the statement that marijuana causes brain damage should be considered unreasonable. However, such statements continue to appear. In a television, advertisement prepared by the “Partnership for the Drug-Free America” ‚Äčorganization and clearly inspired by Campbell’s long-discredited assertion that marijuana leads to brain atrophy, viewers caution “marijuana speeds up the aging process.” The Bulletin of the National Institute of Drug Addiction (NIDA) reports that “animal-supported animal studies have shown structural lesions in the hippocampus – a brain structure that is critical to learning and memory – under the influence of the main psychoactive component of marijuana”. Government reports and brochures on anti-drug education still include warnings that “marijuana kills brain cells”. The more interesting information you can find on essay wanted.

Marijuana study on cognitive abilities

A pilot study published in the journal Frontiers in Pharmacology last month and conducted at the McLean Hospital in Belmonte, Massachusetts, examined the impact of medical marijuana on the executive function. What is the executive function? Imagine a project manager who monitors the execution of work, from the planning stage to the completion. The executive function, therefore, includes both control of attention, and working memory, and restraining mechanisms and mental flexibility.

This research is revolutionary in its own way, as the subjects before they take part in the experiment either did not use marijuana at all or did not do it in the last 10 years. Thus, unlike many other studies comparing a group of smokers and a group of nonsmokers, this was comprehensively evaluated before use and then AFTER. (Or, as opponents of legalization would say, they were specially made drug addicts for the sake of this study.) Thus, all the changes that occurred with the subjects could be safely attributed to the use of marijuana.
