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.
According to the National Institute on Drug Abuse marijuana causes the user to feel euphoric by acting on the brain’s reward system. The euphoria is caused by the release of dopamine it to the user system. Other effects can include heightened sensory perception (e.g., brighter colors), laughter, altered perception of time, and increased appetite. Marijuana also inhibits the formation of new memories and causes coordination and balance to be degraded. These reactions are caused by binding the receptors in the cerebellum and base ganglia. The effect is similar to the impairments that are normally associated with consuming alcohol. Habitual users can also develop acute psychosis, a fundamental derangement of the mind (as in schizophrenia) characterized by defective or lost contact with reality especially as evidenced by delusions, hallucinations, and disorganized speech and behavior (Merriam-Webster Dictionary). The IQ level of a marijuana users also decreases over time according to a Duke University study conducted by clinical psychologist Madeline Meier “people who bega...

About one out of five 10th graders and about 1 out of four high school seniors used marijuana in the past month (Facts for Teens, 1). It is the second most popular drug among teens in the US (Encarta, 1). Teens, ages 12-17, that use marijuana weekly are nine times more likely than non-users to experience with illegal drugs and alcohol (Fed. Study, 1). More 13 & 14 year olds are using drugs, fifteen pe...
Marijuana is taken very lightly and is the most highly used illegal drug. In fact, 1 out of 7 high school students smoke marijuana more than once a day. For this reason, society should know its short and long term effects on the brain. Marijuana can effect these two areas emotionally or physically. Also in some cases physical damages causes the emotional response. Although most public information on drugs are funded by anti-drug organizations, hopefully we will still learn these true facts of marijuana in spite of that.
First of all, some people feel smoking marijuana can get hyper, which providing them the emotion of happiness, and helping them to see the world from a different perspective. However, marijuana will cause a lot of healthy problems to human’s body. Marijuana has many physical effects on human such as rapid heart rate, red eyes and dry mouth. Because the chemical THC will enter into the body when people are smoking it, THC will enter through the bloodstream to the brain. The chemical affects them to feel ecstasy and unreality; therefore, THC will make them feel more confused if people smoke marijuana for a long time. According to, “ Treat marijuana abuse like a health problem” (McMillan, 2007, July 17), it shows using marijuana can cause more serious health issues on human’s body such as bronchitis, emphysema, and cancer. In addition, using marijuana has also been linked to lung damage and affects the respiratory and cardiovascular systems. For example, if marijuana ...
Mekdlawit Demissie IGED 130-06 Informative Speech Outline Topic: Marijuana Speech Goal: To inform the audience about the long and short term effects of marijuana usage. Central Idea: Marijuana is the most commonly used drug amongst young people in the United States. Introduction: I. Attention getter:
Many could argue that marijuana is destructive physically as well as mentally. “The National Institute on Drug Abuse says marijuana can cause heart irregularities, lung problems, and addiction” (Welch). “One joint can be just as damaging to [the lungs] as smoking at least two and a half cigarettes” (Ruff). According to Dr. Tom Wright, director of a substance abuse treatment center for adolescents in Rockford, “teens may be especially sensitive to marijuana’s effects because their brains are still being formed” (MJ Rebuttal). However, the marijuana legalization proposition would have tight restrictions and regulations by the states that would eliminate some of those issues, such as age. These facts are not consistent; the evidence is not backed from reliable sources. One institute is referred to, but more experts are needed to verify the information.
The legalization of marijuana has been a highly debated topic for many of years. Since the first president to the most recent, our nation’s leaders have consumed the plant known as weed. With such influential figures openly using this drug why is it so frowned upon? Marijuana is considered a gateway drug, a menace to society, and mentally harmful to its consumers. For some people weed brings a sense of anxiety, dizziness, or unsettling feeling. Like alcohol, tobacco or any other drug, those chemicals may not respond well with their body. For other people marijuana brings joy, a sense of relief, and takes the edge off of every day stress. For those who are associated with cannabis, purposes usually range from a relaxant, or cash crop, to more permissible uses such as medicine, and ingredient to make so many other materials. We now need to look at what would change if marijuana were legal. Benefits to the economy and agriculture, health issues, and crime rates are three areas worth looking at. Deliberating on the pros and cons of this plant we can get a better understanding for marijuana. From there it will be easier to make a clear consensus on what is best for the nation.
The Effects of Marijuana Marijuana is a mood altering or psychoactive drug that has many nicknames, such as pot, weed, ganja, sensi, herb, and. others. The. It is an ancient drug that dates back to hundreds of years to the Asia. Many cultures have used it during meditation, religious.
The effects of marijuana are minimal. The high has a feeling of euphoria, peacefulness and well-being. Tetrahydrocannabinol (THC) is the active chemical in marijuana. It’s estimated that a person would have to ingest a dose 20,000 to 40,000 times the average dose before death would occur. In the early 1990’s sophisticated research on marijuana began. The scientists discovered THC stimulates special receptors in the brain. Researchers have now isolated a natural substance that appears to produce the same effects as THC in the brain. Recently the medical uses of marijuana are being more and more accepted, and many marijuana smokers wonder how it can be harmful if it helps/treats patients.
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 is the third most common leisure drug in the United States after alcohol and tobacco. Millions of Americans smoke marijuana despite the strict laws against its use. Marijuana is less dangerous compared to tobacco or alcohol. Smoking marijuana can cause breathing problems and coughing just like cigarettes and some people get addicted after using for a while. Regulating and legalizing marijuana will bring Americas greatest cash crop under law, create economic opportunities and jobs in the formal economy as opposed to the underground market. Adopting a legally controlled market for marijuana will ensure that consumers buy the products from a safe and legal source. Marijuana has been approved in some states for medical uses to ease the effects of different health challenges. Colorado and Washington legalized m...
What is Marijuana? The marijuana affects the brain development on teenager. Also affect the function at school, work, and social life of the teenagers. The marijuana increases the risk of mental health issues. The sadistic show that the used of marijuana increase every years. Marijuana affects the teenager and also their families.
The use of drugs and mind-alternating substances has been a part of society for decades. The ‘high’ that people attain from the use of such substances is very attractive and exciting however, the effects of this use are minimized. Particularly for youth, a group of individuals who are seeking independence and experimentation, drug use represents the balance between taking risks and taking responsibility for one’s actions. However, the developmental processes of adolescents are known to not encompass the maturity required to fully think through such decisions. As such, the use of a ‘smaller-scale’ drug like marijuana is even more minimized. The purpose of this paper is to discuss what the risks of using marijuana are for youths, why they are the most affected, how this problem has progressed over the last three decades, and what preventative measures and treatment options are in place. It will also discuss what schools, parents, and government agencies could be doing to help improve the issue, and the impact that this issue is having on society.
People usually smoke marijuana in cigarettes or pipes, but it also can be mixed with food and beverages. Short-term effects of marijuana include both psychological and physical reactions. These reactions usually last for three to five hours after a person has smoked marijuana. The psychological reaction, known as a high consists of changes in the user´s feelings and thoughts. Such changes are caused mainly by THC. The effects of a marijuana high vary from person to person and from one time to another in the same individual. In most cases, the high consists of a dreamy, relaxed state in which users seem more aware of their senses and feel that time is moving slowly. Sometimes, however, marijuana produces a feeling of panic and dread. The different reactions result partly from the concentration of THC in the marijuana. Other factors, such as the setting in which marijuana is used and the userÕs expectations, personality, and mood, also affect a personÕs reaction to the drug. Long-term effects of marijuana are not completely known, but studies have shown that some people have used marijuana regularly for several months or longer have develop serious long-term problems. Among males, marijuana use can reduce the production of sperm and of the male sex hormone testosterone. Among females, it can cause menstrual irregularity and reduced fertility. Extended use of marijuana also has a long-term psychological effect on many people. These individuals loose interest in everything.
People usually abuse marijuana by becoming addicted and smoking it just because instead of using it for their well-being. I went around and asked about ten people I know who have been smoking for at least five years. When I asked them if they had ever experienced memory problems, learning difficulties, trouble with problem solving and loss of muscle activity and addictive capability, they responded, “If anything, marijuana enhances my memory.” “I would not be able to learn in school if I did not smoke.” “The only problem I had, was being addicted to marijuana, but it was all in my head because when I finally stopped smoking, I had no withdrawal symptoms.” The only side effect that seemed to be accurate when asking these questions was the addictive properties. Although being addicted to marijuana mentally can be a problem, all of the many positive side effects of marijuana outweigh the one negative side effect that seems to be the most
