Marijuana Affects The Brain

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

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

Marijuana is a mixture of the dried parts of the cannabis sativa hemp plant. Excessive marijuana use can lead to an addiction. The main chemical in marijuana is tetrahydrocannabinol (THC), which moves quickly through the bloodstream and to the brain, causing mild hallucinogenic effects. THC binds with cannabdnob receptors and activates neurons, which causes adverse effects on the mind and body. THC can mimic or block actions of neurotransmitters and interfere with normal functions. Marijuana use can lead to disturbed thoughts and can worsen psychotic symptoms. The short-term effects of marijuana include impaired coordination; skewed sensory and time perception; difficulty with thinking; shortened attention span and distractibility; impaired learning and memory. Long term users of marijuana often experience lowered motivation and some can experience anxiety, panic attacks, respiratory illness, and increased heart rate and risk of heart attack.

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.

THC, the active ingredient in pot works on specific parts of the brains hardware, called cannabinoid receptors. Turning on a cannabinoid receptor with THC creates a bunch of cellular reactions that at last create to the "high" that you feel when you smoke weed. Cannabinoid receptors exist throughout the brain. They are most common in parts The areas of the brain that influence pleasure, time, memory, and concentration have the highest concentration of these receptors. Smoking weed frequently can overpower

For many years scientists have conducted studies about marijuana and the different effects that it has on the mind and body. Marijuana smoke can cause many of the same respiratory problems experienced by tobacco smokers, such as increased daily cough and chest illnesses such as bronchitis, and a greater instance of lung infections, according to NIDA. Whenever a person smokes marijuana, THC quickly passes from the lungs into the bloodstream. Tetrahydrocannabinol (THC), a crystalline compound that is the main active ingredient of cannabis (Oxford, 1960). The blood carries the chemical to the brain and other organs throughout the body. The body absorbs THC more slowly when the person eats or drinks it. THC acts on specific brain cell receptors

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.

How does marijuana even affect the user? The key ingredient in the herb is called THC which stands for Tetrahydrocannabinol. THC is the chemical compound that stimulates the neurotransmitters in our brain that release dopamine. Dopamine is what gives the user a euphoric feeling. The THC cannabinoid receptors affects the hippocampus in the human brain by slowing down the process of memory. It also affects

Marijuana affects the brain significantly. The prefrontal cortex, which helps make decision and understand consequences, is affected because marijuana alters blood flow to your brain which impairs judgment. In the cerebral cortex pot messes with perception, judgment and problem solving, causing users to do things they normally wouldn't. Pot affects the limbic system, which is the emotional center of the brain. The limbic system is the most influenced by marijuana because the THC in marijuana links to cannabinoid receptors creating a memory of the drug that can lead to addiction. Lastly marijuana affects the cerebellum which controls physical coordination. The THC in marijuana interferes with signals being sent to the cerebellum making movements difficult to perform.

No matter how it gets into your system, it affects almost every organ in your bod. When you smoke pot, your body absorbs the THC right away and goes straight to your blood stream. When smoking It in a cigar form, not only are you smoking the weed part, you’re also smoking the harmful Tabaco ingredients in the cigar. Tobacco smoke is made up of thousands of chemicals, including at least 70 known to cause cancer. These cancer causing chemicals are referred to as carcinogens. Some of those ingredients include; nicotine, Ammonia, Arsenic, Benzene, Carbon monoxide, Formaldehyde, Hydrogen cyanide, Lead, Nitrosamines, Polycyclic aromatic hydrocarbons, and Radioactive elements, such as uranium. When consuming it through a food or beverage, it may take much longer for your body to absorb THC, because it has to break down in your stomach before it enters your bloodstream. Your body may feel different right after you smoke but it takes close to 45 minutes to kick in if you eat it.The effect of marijuana usually stop after 3 or 4 hours. Smoking weed can increase your heart rate and blood sugar by as much as two times for up to 3 hours. That’s why some people have a heart attack right after they use marijuana. It can increase bleeding, and effect your blood pressure ,too. Some other physical effects of marijuana are; Dizziness, Dry mouth, Increased appetite, Red eyes,

This periodical article explains how marijuana , especially the substance 9-delta-tetrahydrocannabinol, affects the brain. The article pointed out how THC affect different body functions. According to this article, studies have revealed that there is a communication system named the endocannabinoid system that is mean how marijuana act in the body. This system is composed of a substance cannabinoid (CB) receptors that are found in many areas of the brain. That is why marijuana affects different body functions. The author affirms that when someone smokes marijuana, THC gets into the brain rapidly and attaches to cannabinoid receptors. The natural endocannabinoid (EC) system is tuned to react appropriately to incoming information. The EC system

In the article “What are Marijuana Effects?” it says, “When marijuana is smoked, THC and other chemicals in the plant pass from the lungs into the bloodstream, which rapidly carries them throughout the body to the brain. The person begins to experience effects almost immediately.” It is also known that if marijuana is consumed through food or beverages the effects are delayed.

Marijuana affects the Central Nervous System (CNS). THC resembles a natural transmitter in our brain called Anandamide. Cannabinoids are specialised neurotransmitters released by neurons. The neurons become temporarily unresponsive after firing to prevent them from overreacting of being too dominant. This allows the brain to function in a calm and controlled manner, however cannabinoids interrupt this approach in some parts of the brain instead, they remove the refractory period of neurons that are already active, which causes the person’s thoughts, imagination and perception to magnify itself. Therefore, their thoughts become profound and tend not to recall anything since they’re caught in the momentum of a particular idea and their neurons

While smoking marijuana people sometimes don't feel anything. Others may feel “high” or relaxed as well as increasingly hunger (the munchies). Effects of marijuana can also make you have paranoid thoughts and anxiety. Your high will only last for up to 2 hours. Most intense effects come within minutes and start to wear off after an hour.
