Research Design (Assignment 2)
I will be conducting a study using a true experimental research design in order to investigate the effects of marijuana use on an individual’s problem solving ability. Marijuana use is the independent variable which is operationally defined as consumption in the form of smoking 0.5 grams of cannabis in a marijuana cigarette. Problem solving abilities is the dependent variable which is operationally defined as the total score on various math problems as well as time taken to complete said math problems. Scores on the math test can range from 0 to 100. 40 participants, 20 males and 20 females all of whom are 18 year old Freshmen taking Math 131 at Pasadena City College, will be utilized in this study. 10 males and 10 females will be randomly assigned to group A and will all smoke marijuana, while 10 males and 10 females will be randomly assigned to group B and will not smoke marijuana. In order to ensure that every participant in group A is affected by the marijuana equally, only students that consent to a drug test prior to the study and are found to have no traces of THC present in their blood will be eligible to participate in the study. This will ensure that all participants in group A are affected by marijuana equally by eliminating the possibility of one participant having a higher tolerance than another.
In order to eliminate all possible plausible alternative explanations for the relationship observed between marijuana use and problem solving abilities, all aspects of the environment will be controlled. Each member of group A will consume 0.5 grams of marijuana collectively within the same environment and then be led into a singular room where the math test will be administered. Likewise, each member of group B will be led into a separate but identical room where they will be administered the same test. The math test will

Legalize Pot You Must Be High Summary

...evidence that shows that marijuana is dangerous that it is safe. According to Marty Nemko’s article ‘Legalize Pot? You Must Be High’, the intensive research that has been done to find out the harms that derive from the drug “may cause far greater damage than once thought” (Nemko 1). Studies have been conducted and found that marijuana can result in dependence in 9-10% of users. While this figure is low, and the validity can be questioned, it is still a potential harm. It may be the basis for something worse that scientists have not yet discovered. Other research suggests that marijuana negatively affects the ability too learn and remember new information, and can lead to “significant abnormalities in two key brain regions” (Nemko 1). Furthermore, users of marijuana can experience severe anxiety, panic, or distressful thoughts like nightmares. Nemko stresses the change in the world that...

Legalization of Marijuana

...billion dollars? How could the nation get this much money in one year? The legalization of marijuana would bring such profit. Replacing “marijuana prohibition with a system of legal regulation would save approximately $7.7 billion in government expenditures of prohibition enforcement --$2.4billion at the federal level and $5.3 billion at the state and local level.” (Miron). The money generated from this could be used for so many needs of the nation. For example, one immediate use would be to help restore the foundation of bridges and roads. The United States economy is currently suffering and the simple act of legalizing marijuana would help stimulate the economy. This act also will help struggling citizens with life threatening conditions reduce their suffering. There are numerous benefits to legalizing marijuana including eliminating a portion of the wasteful War on Drugs, stimulating the United States economy, and helping many patients relieve their pain. In order to truly understand the benefits of the legalization of marijuana, it must be discussed why it was made illegal in the first place. In 1914, the Harrison Act “represented the first time drug use had ever been defined as a crime” (Goodwin 42). This law set the precedent for twenty-seven states to make marijuana illegal. There states made marijuana illegal because they mistrusted the incoming Mexican immigrants who brought marijuana with them. (Goodwin 42-43) Therefore, the laws were not enacted for safety or health reasons...

Proposition 19: Legalization of Marijuana

...In 1996, medical marijuana became legal in California, which inspired Richard Lee to open businesses associated with the usage of marijuana. Lee was a medical marijuana provider and activist with a dream to legalize marijuana; as a result, he created Proposition 19 in 2010 by using his own funding to the sum of $1.45 million. The creation of Proposition 19 was to legalize marijuana in California through regulation and taxation. In essence, passing of the bill would legally allow individuals that are 21 or older the ability to harvest and use marijuana. However, Proposition 19 would only grant legal rights related with marijuana under the state of California and not under federal law. As a result, federal law must still firmly enforce drug laws against harvesters and distributors of marijuana in California. Although Proposition 19 was unable to pass in 2010, Lee ensures that effort to pass this bill will never stop. Proposition 19 protesters argue that legalizing marijuana creates abuse among adolescents. In the article “Why We Should Not Legalize Marijuana”, Dr. Robert L. DuPont stated, “Marijuana is the most commonly abused illegal drug in the U.S. and around the world.” The United States Drug enforcement Agency has classified marijuana as a drug that has an extreme potential for abuse. They categorized marijuana as a schedule I drug which is under the same category as cocaine, heroin and morphine. Parents fear that the legalization of marijuana enables easier access...

Anti Marijuana

...be bad” is one of the many lies marijuana users tell themselves in order to indulge themselves on this so called “medicine.” Marijuana users claim the drug makes them feel good, it makes them calm down. They also say marijuana is not a drug, and not nearly as harmful as other drugs and alcohol. But, are these claims correct? Of course not. These are some of the many lies marijuana users tell others in order to spread the use and legalization of this drug. According to recent statistics from “DrugFreeWorld.org,” cannabis is the number three in the top five harmful substances which account for admission into drug treatment facilities in the United States. Although users may argue marijuana is not nearly as harmful as it has been perceived through the media, the drug wreaks havoc on a person’s health, destroys families and leads to prolonged and free drug abuse. The risks of using marijuana far outweigh the “benefits” of the drug as it can lead to health issues regarding the heart, lungs, and brain. According to “AddictionBlog.org” the most common reasons people use marijuana are to relax, curiosity, and its deceptively low perception of harm. Yet, most of the users of marijuana are so ill informed of what the drug actually does to their bodies. Admittedly for most users of marijuana, it does “relax” the user in distorting their perception of the world; however, this temporary fix only leaves permanent damage. Prolonged use of marijuana has proven to be linked with loss...

Why The Death Penalty Is Unnecessary

...As President, I want to create more problem solving issues on Abortions, Death Penalty, and Drugs. As president, I am more concern for the people and only want to make these problems disappear or at least start to be resolved. I think abortions are unnecessary and if you cannot for any reason keep your child, it is a smart decision to put your child up for adaption and someone who wants to take care of them can have the opportunity to do so. I also think the death penalty is unnecessary because this is bringing murder upon a criminal who has done something bad. The death penalty should be eliminated and non existing. Last, I would like to change the ability of people consuming these dangerous drugs and how some drugs should and should not be illegal. First, Abortions should be illegal and demolished because having an abortion is very unnecessary. If a person don’t have the ability to take care of her baby, then it is best to put the baby up for adaption. I think the only reason for n abortion is if it is a serious or dangerous cause for the mother to not have the ability to have the baby. I also think that if a parent decide to have an abortion, it needs to be a limit on how many weeks the baby is in order to do so. Abortions cost approximately $300 to $800 dollars. I think the cost for an...

Decriminalization of Marijuana

...DECRIMINALIZATION OF MARIJUANA ******* English 112 ********** April 18, 2012 Presently, Marijuana is illegal in the United States due to the racially motivated Marijuana Tax Act of 1937. This law was proposed by Harry J. Anslinger the acting commissioner of Federal Bureau of Narcotics. In his testimony to Congress he stated, "There are 100,000 total marijuana smokers in the US, and most are Negroes, Hispanics, Filipinos and entertainers. Their Satanic music, jazz and swing, result from marijuana usage. This marijuana causes white women to seek sexual relations with Negroes, entertainers and any others" (ukcia.org, (n.d), para. 1). Since this time, the Marijuana Tax Act of 1937 has spawned more strict laws that have many unintended side effects. After many decades, effective federal propaganda has won public support for these laws. Only recently, U.S. citizens have started to question why marijuana is illegal. I feel that it would be beneficial to discard these laws and beliefs of the past. We need to analyze how the legalization of marijuana would positively affect the United States and its citizens in the following fields: medical, criminology, and financial. I support the legalization of marijuana not because I use this herb, because I do not and would not even if it was legal much like a majority of our populous. I have taken this stance because of the benefits that would arise from legalization. Marijuana has been criminalized for private citizens since 1930’s bringing...

The Viability of the Decriminalization of Marijuana for Medical Use and Its Benefit to Jamaica

...but is this the most rewarding use of marijuana? Would the development of a medical marijuana industry prove more beneficial to Jamaica? Would the decriminalization of marijuana in order for such an industry to be enacted be economically viable? Other questions to ask ourselves are, what is Decriminalization and how would decriminalization of marijuana help with enacting a medical marijuana industry? According to the Merriam-Webster decriminalization means “to remove or reduce the criminal classification or status of; especially: to repeal a strict ban on while keeping under some form of regulation”. Marijuana currently is a banned drug in Jamaica and for Jamaica to develop a medical marijuana industry which would therefore means large scale production of the drug for scientific research and medicine production. The drug would have to be legalized on a certain level to facilitate such. Note in the above definition for decriminalization it made mention of the drug being kept under some form of regulation which for this research basically means certain punitive usage of the drug would still be rendered as illegal. The scope of this research paper will cover areas such as, the economic state of the country and its ability to facilitate and withstand such an industry, the illicit use of the drug, implementations of stringent control measures and use of the substance, inabilities to export due to certain treaty and acts and the negative effects of the recreational use of the drug. ...
