The active ingredient in marijuana is “tetrahydrocannabinaol” or THC. Smoking marijuana draws the THC from the lungs to the brain where it suppresses neurons causing distortions of time and perception. It also causes lack of coordination, feelings of euphoria, heightened sensitivity, paranoia, and sometimes uncontrolled hilarity. Within seconds of smoking marijuana muscles relax, eyes redden and pulse rate increases. Marijuana is a plant that can grow and thrive just about
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
Long-term effects of alcohol are liver cirrhosis, stomach ailments, impotence, vitamin deficiency, increased stroke risk, decreased mental performance, heart disease, peptic ulcers, hepatitis, and various forms of cancer. Alcohols effects on the brain are loss of coordination, poor judgment, slowed reflexes, distorted vision, memory lapses, and even blackouts. Long-term effects of marijuana are mouth, throat, and lung cancer, increased heart rate, decrease in testosterone levels for men, increased testosterone levels for women, diminished sexual pleasure, increased blood pressure, increased stress, decreased motivation, and respiratory problems. The THC in marijuana damages the nerve cells in the part of the brain where memories are formed, making it hard to remember things.
Marijuana is the third most popular recreational drug in America, after alcohol and nicotine products. It is a greenish-gray mixture of the dried, shredded leaves and flowers of cannabis sativa, the hemp plant. The main psychoactive part of cannabis is tetrahydrocannabinol or also known as THC. It contains THC as well as over a hundred other cannabinoids. THC is a psychoactive chemical. Marijuana is often used for its mental and physical effects such as a “high” or a “stoned” feeling. It has been know that there are benefits to using marijuana such as euphoria or heightened mood, increased appetite and many others. However there are short term side effects which may include dry mouth, decrease in short term memory, red eyes and often

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.
Marijuana has been used in the treatment of AIDS, cancer, glaucoma, multiple sclerosis, and chronic pain ("Medical Cannabis."). Researchers have been trying to explain the negative effects that marijuana can have on the central nervous system and how it hinders memory as well. The constant reports of short-term memory loss by heavy marijuana users brings up the question, is it the most common long term effect of marijuana use? Although it is said that marijuana has many effects such as exhaustion, increased appetite, offset sense of time, and bloodshot eyes, short-term memory loss is the symptom most frequently linked with the use or ingestion of marijuana. But why? Why does using marijuana have any impact on a person’s memory at all? Countless scientists have been working tirelessly to find an answer for this question. The active ingredient in marijuana, THC, is known to attach itself to areas of the brain linked to memory. When the scientists injected lab animals with THC at Rutgers University, they found that they acted as though there was no rhythm to their thought. It affected the hippocampal circuits in the brain to produce animals that were acting normal but in a delayed or offset manor.
Marijuana does impair short-term memory, but only during intoxication. Although the authoritative studies on marijuana use seem to agree that there is no residual impairment following intoxication, persistent impairment of short-term memory has been noted in chronic marijuana smokers, up to 6 and 12 weeks following abstinence.
Researchers believe that marijuana blocks the messages going to your brain and alters your perceptions and emotions, vision, hearing, and coordination. A recent study of 1,023 trauma patients admitted to a shock trauma unit found that one-third had marij
Cannabis has copious amounts of effects on your body and brain. The effects range from bad all the way to good. Negative effects of cannabis may include anxiety, paranoia, and lowered reaction time, increased heart rate, distorted sense of time, and in some cases, psychosis. Cannabis does have positive effects for people with illnesses including cancer, multiple sclerosis, and many more. For teens, however, there is an increase of cannabis’ negative effects on the brain. This may include decreased brain activity, decreased neurons, trouble thinking and focusing, and a higher rate of dropping out of high school. Chronic users of cannabis may become dependent on it. It can also increase your rate of respiratory problems,
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
One region of the brain that contains a lot of THC receptors is the hippocampus, which processes memory. When THC attaches to receptors in the hippocampus, it weakens short-term memory. The hippocampus also communicates with other brain regions that process new information into long-term memory. In the brain, under the influence of marijuana, new information may never register, and may be lost from memory.
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.
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
