Cannabis and Cognitive Functioning
The debate concerning recreational and medical use of cannabis has historically been incredibly controversial and its popularity is increasing. Many claim that there are no downsides to its use, often falling back on the “alcohol is worse for you” argument, while those who oppose its use say otherwise. In 2013, the Substance Abuse and Mental Health Services Administration (SAMHSA) surveyed 70,000 Americans 12 years and older and found that 7.3% of Americans regularly used marijuana in 2012, showing a rise in use over the last several years. While cannabis is still considered an illegal substance in the majority of the country, several states are beginning to shift their views, allowing for the use of medical marijuana in some and even full legal recreational use in others, such as Colorado. The main question driving this debate is how does cannabis affect the mind? Legalization very much depends on peoples’ health and safety concerns, and so in this paper I discuss cannabis and its effects on cognitive function both short- and long-term.
Cannabis is the substance originating from the plant Cannabis sativa, which can be found in regions all over the world (Solowij, 13). The plant itself contains more than 60 cannabinoid compounds, but the primary psychoactive compound is delta-9-tetrahydrocannabinol (THC) (Gaoni & Mechoulam, 1964). Howlett and Colleagues found that cannabinoids inhibit the enzyme that synthesizes cyclic AMP in cultured nerve cells. As many receptors relay their signals to the cell interior by changing cellular cyclic AMP, this evidence suggests that cannabinoids were not just dissolving nonspecifically in membranes, but rather acting through their own receptors (Howlett et al., ...

...d during acute cannabis intoxication and over the course of years of recreational cannabis use. While all of this may be true and support the claim that marijuana should remain illegal, the debate will continue, especially as it seems the country and other parts of the world are beginning to lean more and more towards its’ legalization.

The purpose of my paper is to prove that marijuana effects teens and their mind. Marijuana is a tobacco-like substance produced by drying the leaves, stems, flower tops of the Cannabis sativa (Indian Hemp) plant (Fact Sheet, 1). It is smoked or eaten to get hallucinated and receive pleasure. It grows just about anywhere. It is illegal in some countries but in others it is used for medical purposes (Encarta, 1). Some names that it is called a joint, nail, pot, Mary Jane, hive, etc. (Fact Sheet and Facts for teens, 1). Marijuana stays in the body for several days after one smoking session. In a chronic user marijuana can stay in the body for up to several weeks (Facts for Teens, 1).
Although most public information on drugs is funded by anti-drug organizations, hopefully we will still learn the true facts about marijuana. The brain is the most complicated part of the human body. I will begin by explaining certain parts and their functions. In doing this I hope to give a better understanding of our brain while implicating the possibilities of chemical induced complications “The brain with its 15 billion neurons and nerve cells operates using chemical and electrical messages” (Swanson, 1975).1 This is how we perceive our senses. Differences in the way our brain translates these messages can impair perception.
Marijuana is a drug that is harmful to a person¡¯s health. It has been found to have adverse impacts on one¡¯s mental processes such as memory, attention, judgement, and problem- solving (Butcher, Mineka, Hooley, 2004, p.415). Also, marijuana can interfere with a person¡¯s ability to think rationally and logically. Thus, the lapse in judgement caused by the drug use can lead to risky sexual behaviours and this may result in increasing sexually transmitted disease such as AIDS. Moreover, the long-term use of marijuana may cause chronic breathing problems and cancer ...
There has always been controversy about marijuana and the affects it has on health and the issue of legalization. Some people believe it is very destructive to one’s health, and yet others feel the complete opposite about it. Is Marijuana truly harmful to one’s health? “Marijuana, the Deceptive Drug”, written by George Bierson, was published in the Massachusetts News. In this article, Bierson determines that marijuana is harmful in many ways. He seems to think that it damages the brain, the reproductive system, and also contributes to the halt of production in the immune system. Bierson also tries to persuade the reader that marijuana is a “gateway drug” that leads to larger drugs in the future. However, by conducting research of my own, I have come to the conclusion that Bierson’s article simply lacks truth.

The human body produces naturally occurring cannabinoids. The cannabinoids are lipophilic. Delta-8 and Delta-9 Tetrahydrocannabinol (THC) have been found to produce most of the psychoactive effects of marijuana (Carter et al., 2003). Delta-9 Tetrahydrocannabinol appears to be the most abundant cannabinoid and the main source of cannabis' impact. Cannabidiol is
Marijuana while illegal on a federal level has been legalized in 18 states and the District of Columbia for medical use and also for personal use for anyone over 21 in Washington and Colorado. 48% of Americans admit to using marijuana according to a 2013 survey conducted by Scientific America. With the change in public opinion concerning marijuana the need to understand the effect and consequences associated with its use are vitally important. What are the effects on the brain and the rest of the body? Does it matter when you start using marijuana? Also what is the effect marijuana use has on a person’s life, to include school, work, family and friends.
“A marijuana high can enhance core human mental abilities. It can help you to focus, to remember, to see new patterns, to imagine, to be creative, to introspect, to empathically understand others, and to come to deep insights. If you don’t find this amazing you have lost your sense of wonder. Which, by the way, is something a high can bring back, too.” - Sebastian Marincolo (Goodreads).

In this article, Kristen Weir reviews the effects marijuana has on the developing brain. As more states are now legalizing marijuana for not only medical but recreational use, many medical doctors and psychologist fear the long-term effects. Many of marijuana’s long-term effects are still unknown even though it is one of the most widely used illegal substance in the United States. Recreational use in states that marijuana is legalized in only pertains to citizens 21 or older. Even with the age restrictions, some doctors still fear the legalization of marijuana recreational will allow the drug to become more accessible to younger adults or adolescences. Susan Weiss, the director of the division of extramural research at the National Institute on Drug Abuse (NIDA), voiced her concerns on the topic stating, “There are a lot of open questions…. But there 's a growing literature, and it 's all pointing in the same direction: Starting young and using frequently may disrupt brain development." (Weiss). As she acknowledges the fact that there is a “growing literature” when it comes to marijuana use and its effects, she also admits the new research is all leading to the same conclusion, frequent use and starting young may disrupt normal brain development. The government and other private institutions are funding and researching these unknown effects.
Marijuana continues to be one of the most used illegal drugs in the United States. Marijuana has been used for many years and at one time was legal to consume. Throughout the years, marijuana has been used for treatment of different medical conditions and has been used recreationally by people of all ages. While the use of medicinal marijuana has proven to be effective in treating medically ill patients, society continues to question its recreational use and the long term effects it will have on its users. Some feel that legalizing marijuana will only open up avenues for the use of more potent drugs, causing an increase in criminal activity. However, a number of people question why it is considered illegal being it is a naturally growing
