Smoking: The Memory Killer. Over The Years, There Has Been

Marijuana can have very damaging affects on a person?s brain. It can impair a person?s short-term memory, decision-making and signal detection (Cannabinoids). ?In one study conducted in Memphis, TN, researchers found that, of 150 reckless drivers who were tested for drugs at the arrest scene, 33 percent tested positive for marijuana? (Marijuana). After having used marijuana a

THC disrupts the nerve cells in the part of the brain where memories are formed. This makes it hard for the user to recall recent events (such as what happened a few minutes ago), and so it is hard to learn while high. A working short-term memory is required for learning and performing tasks that call for more than one or two steps. Some studies show that when people have smoked large amounts of marijuana for many years, the drug takes its toll on mental functions. Among a group of long-time heavy marijuana users in Costa Rica, researchers found that the people had great trouble when asked to recall a short list of words (a standard test of memory). People in that study group also found it very hard to focus their attention on the tests

It is true, of course, that marijuana kills brain cells and tissue. Smoking or consuming marijuana in any way can be very harmful to the brain (Katel). Though there is no convincing scientific evidence that marijuana causes psychological damage or mental illness in either teenagers or adults, marijuana users will experience loss of brain cells, which can be dangerous but does not cause permanent mental illnesses. The human brain is required to live, breathe, and carry out any action throughout life. Consuming massive amounts of marijuana will destroy brain cells, which are vital to trigger thoughts, movements, interactions, and memory. The tissue within our brains eventually corrode due to marijuana usage. Like all tissues and organs in the human body, brain tissue serve many different functions, and when the functions are limited, the tissue deteriorate (Borden). Daily use of marijuana could make the smoker experience psychological distress following marijuana intake, which may include feelings of panic, anxiety, paranoia, and loss of memory.

Marijuana creates many short-term and long-term effects on the body and brain. Some short-term effects include: impaired memory, altered senses, changes in mood, and difficulty with problem solving. Some long-term effects include: breathing problems, reduce memory, and decrease IQ. A study from New Zealand conducted in part by researchers at Duke University showed that people who started smoking marijuana heavily in their teens and had an ongoing marijuana use disorder lost an average of 8 IQ points between ages 13 and 38. The lost mental abilities didn't fully return in those who quit marijuana as adults (National). This study can be seen as reliable evidence because it was conducted by researched from Duke University, which is a private research

Smoking tobacco is more harmful to your lungs than smoking marijuana. It only takes a couple inhalations of marijuana smoke to become high. Let’s say you’re addicted to cigarettes and smoke a pack a day, keeping in mind that cigarettes are legal. To get high off of marijuana it would only take about a fourth of the tobacco you inhale in just one cigarette, just to become high. When you smoke cigarettes you are continuously inhaling tar, nicotine, and many other chemicals that harm your lungs and may result in lung cancer.

Studies have proven that marijuana is no more harmful to a person’s health than alcohol or tobacco. Every year, tobacco kills roughly 390,000 people, alcohol contributes to 80,000 deaths in America and marijuana contributed to 0; no deaths from marijuana have ever been recorded in US history (Abovetheinfluence.org). When smoking tobacco, the user inhales tar, nicotine, carbon monoxide, and 200 other known poisons into the lungs (Abovetheinfluence.org). All forms of tobacco, including cigars, pipe tobacco, snuff, and chewing tobacco, contain the addictive drug nicotine, and can also cause cancer. Alcohol alters a person's perceptions, emotions, movement, vision, and hearing. Alcohol plays a role in at least 50 percent of traffic deaths, about half of murders, and about 25 percent of suicides (Abovetheinfluence.org). Marijuana side effects include delusions, impaired memory, hallucinations and disorientation, which are no different from the side effects of alcohol alone.

Marijuana has its strongest long-term impact on young users whose brains are developing and maturing. Researchers see a decline in verbal ability as well as general knowledge in children between ages 9-12. (National Institute on Drug Abuse August

There is no evidence that marijuana use causes brain damage. Studies performed on actual human populations will confirm these results, even for chronic marijuana users (up to 18 joints per day) after many years of use.

This effect can last up to several hours after the drug has been smoked (National Institute on Drug Abuse ). The brain is another thing affected by smoking marijuana, leading to loss of memory in the brain. The nervous system also is affected when using this drug (National Institute on Drug Abuse). Loss of memory and the effects it has on the nervous system alone should raise concern for the American people. Continuing on with heath issues associated with the use of marijuana, it is proven to impair the immune system and can also promote tumor growth (Taylor). The immune system is essential to keep healthy because this is what fights off other illnesses within the body. Increased risk of lung cancer, and cognitive difficulties all can be associated with the use of marijuana (Wilbur). Research has proven smoking marijuana affects health several ways; even though most have been discussed take a look at the following chart, it will help visualize some health issues that are associated with smoking marijuana.

Nowadays there is a big dilemma to whether legalize marijuana or not and whether marijuana is really a lot more dangerous than tobacco. There are big differences between the two of them, but there is, without any doubt, one that has a lot more negative effects on the human body and the human brain than the other. Due to research we can compare them and conclude which one is worse.

I constantly hear that weed does not harm you, this is false. “Marijuana contains more than four hundred known chemicals, including the same cancer-causing substances found in tobacco smoke”. (Alcohol vs. Marijuana, 2013). Let that sink in for a second, it has four hundred known chemicals in it that does not sound healthy for you. I also found out that “ It has been found that consuming one joint gives as much exposure to cancer-producing chemicals as smoking five cigarettes”. (What is Marijuana, 2013). One joint is the equivalent as smoking five cigarettes, but weed is harmless, I think not. Marijuana also affects your mind to where you cannot remember things. Marijuana smokers do not have the same ability to remember and organize information compared to people who do not smoke.

Marijuana continues to be the most widely used drug in the Western Hemisphere, its cognitive effects robustly revolve around memory. There have been many studies done on the chemical effects that marijuana has on the brain centers concerned with memory and learning. There are more productive studies relating to the effects of cannabis on short-term memory that show different memory processes effected by this drug. Though there is not much knowledge on the effects the drug has on long-term memory due to suspected confounds that temper with the process of collecting proper data, there have been studies showing lasting effects in adolescents and chronic users (Schoeler and Bhattacharyya, 2013). More research should be done on the long-term processes in order to better understand the lasting effects of cannabis use. Marijuana causes these adverse effects on memory by first altering chemical processes in the brain.

     Short-term memory is very important in our everyday lives. It is what allows people to remember many various things such as, phone numbers, directions to a friends house, and so on. Short-term memory impairment is fairly obvious with marijuana users. Many of the times users frequently forget the beginning of a conversation, or even the beginning of a sentence, but regularly they are still able to complete what they were saying without any knowledge of the topic (Tart, 2001). It is still unknown why this happens, but it is feasible that it relates back to the problem of too much information being processed faster then usual, allowing for distractions to take over the person’s mind, making them forget what they were originally talking about.

The article, “Marijuana and the Teen Brain”, from the Scientific American journal, Claudia Wallis, argues that marijuana negatively affects the teenage brain. Wallis begins her argument by stating her viewpoint on the drug and then proceeds to provide information to support her stance. Multiple studies by scientists/researchers are cited in this article including those based on x-rays of a marijuana user’s brain and others that tested marijuana users on their cognitive skills. Wallis additionally mentions a study on rats which tested the effects of THC. The author provides background information on marijuana to give the reader a better understanding of the concept. This source supports the argument that marijuana use has negative impacts on the human brain because the author also stands behind that argument. Wallis discusses these negative impacts and provides evidence to support her claim. This source cites various studies in which researchers tested the effects of marijuana on the brain which reinforces the argument that marijuana has abnormal effects on the human brain.

Marijuana usually does not contain more than 1 percent of THC. There are stronger drugs related to THC, such as "hash oil", which can contain up to a 28 percent THC level. There have been some cases where "street" marijuana has been found to contain up to 5 percent THC content. That is very potent for normal marijuana, and is probably very hard to come by in the United States. Other countries seem to use different forms of THC related drugs such as hashish, and hemp. Both of these contain more THC than marijuana. As far as long term effects of tobacco and marijuana go, they are about the same. Cancer should appear in the lungs of a tobacco-user earlier due to the amount the tobacco-user smokes in relation to a normal marijuana smoker. There have been many assumptions that marijuana will cause long term brain damage and so on, but, clinically, none of this has ever been proven. In fact, in a college survey, the students who use the drug regularly possessed a higher GPA than those who do not use. This is an entire different subject, but it was interesting to learn.
