THC (TetraHydroCannabinol) is found in marijuana, a mixture of the dried flowering tops and leaves from the plant cannabis sativa. This chemical, THC, is responsible for the euphoric feeling associated with smoking marijuana. Marijuana contains over 400 different chemicals. THC belongs to a group of chemicals found in marijuana called cannibinoids. There are only 60 of these cannibinoids known at present, all of which can only be found in marijuana. THC is the main psychoactive cannabinoid in marijuana. The concentration of THC and other cannabinoids in marijuana varies greatly depending on growing conditions, plant genetics, and processing after harvest. In the usual mixture of leaves and stems of marijuana, concentration of THC ranges from 0.3 percent to 4 percent by weight. However, specially grown and selected marijuana can contain 15 percent or more THC. So, a marijuana cigarette weighing 1 gram (g) might contain as little as 3 milligrams (mg) of THC or as much as 150 mg or more. THC can stay in someone’s system from 20 hour to 30 days, although the "high" produced by THC often does not exceed 2 hours. The human body breaks the THC down into metabolites. These metabolites, 11-hydroxy-THC and 11-nor-9-carboxy-delta-9-THC, are what is stored in your fat cells, not the chemical which causes the psychoactive effect. Because these metabolites carry the prefix THC, many anti-drug activists are able to claim that marijuana stays in your body for much longer, and keeps you high for days of weeks. The delta-9-THC that is found in marijuana must be broken down into these water-soluble molecules before they can be removed from the body. THC is quite potent when compared to most other psychoactive drugs. Large doses of THC delivered by marijuana or administered in the pure form can produce mental and perceptual effects similar to drugs usually termed hallucinogens or psychomimetics. Although the chemical can be very potent, lethal doses of marijuana in humans are not known. There is much we do not know about THC and the effects it has on humans both mentally and physically because until recently the research on the chemical was mainly limited to the pure form tested on young males who had previous experience with the effects of THC. Even today, testing the effects of THC via smoking a marijuana cigarette can be very difficult because of a person's smoking behavior during an experiment is hard for a researcher to control.
After smoking, or consuming marijuana, it is distributed in the brain. The concentration of marijuana in the brain may be governed by an active transport process in the choroid plexus network of blood vessels in the brain which regulates intraventricular pressure by absorption and secretion of cerebro spinal fluid. one scientific experiment it gave an example of how the distribution of marijuana in the central nervous system could effect man. At a high dose of 30 mg./kg. marked sedation and pronounced motor incoordination peaked at the one hour interval subsiding in 8 hours when over reaction occurred to external stimuli; man reveals incapacitation of cognitive and motor function. High concentrations of marijuana are usually found in the following parts of the brain: the frontal cortex (the general association area), and hippocampus (short term memory and oreintation). As a result, perception of time, mood and general cordination is impaired. It is apparent that marijuana intoxication effects the neurological functions and usually disappears in 24 hours, but can become a permanent malfunction.THC effec...
Marijuana is a drug that is harmful to a person¡¯s health. It has been found to have adverse impacts on one¡¯s mental processes such as memory, attention, judgement, and problem- solving (Butcher, Mineka, Hooley, 2004, p.415). Also, marijuana can interfere with a person¡¯s ability to think rationally and logically. Thus, the lapse in judgement caused by the drug use can lead to risky sexual behaviours and this may result in increasing sexually transmitted disease such as AIDS. Moreover, the long-term use of marijuana may cause chronic breathing problems and cancer ...
Marijuana has a long medical history, ranging from its anecdotal use in ancient times, through medical prescribing in the 19th and early 20th centuries to modern. "The first record of cannabis as a medicine can be found in the oldest Chinese pharmacopeia, Shen Nag Ben Cao Jing, written in the Eastern Han Dynasty (25 AD to 220 AD). It was indicated for rheumatic pain, malaria, constipation, and disorders of the female reproductive system" (Greenwell, 2012, Vol. 26 Issue 1). Pain is one of the most common reasons that medical cannabis is recommended. "Scientists have long known that tetrahydracannabinol (THC), the active ingredient in marijuana, is an effective pain killer" (Mcdonagh, 2003). Studies of medical marijuana show significant improvement in various types of pain. "Marijuana appears to exert its pain relieving effects by acting on certain sites in the brain and spinal nerves. These specific sites are called cannabinoid receptors. The cannabinoid compound connects to these receptors, much like two puzzle pieces fitting together. Once, joined, the receptor alters the way the brain cell or nerve cell functions. This alteration of function changes the way the cell perceives painful stimulus, often reducing the intensity of pain that is interpreted by the brain" (Greenwell, 2012, Vol. 26 Issue 1). "The effect that cannabinoid compounds have on the cannabinoid receptors (CB1 and CB2) found in the brain can create varying pharmacologic responses based on formulation and patient characteristics" (Borgelt, Franson, & Nussbaum, 2013). Several small clinical studies have confirmed the usefulness of THC, which at doses of 15 to 20mg was found to be comparable to 60 to 120mg pharmaceutical painkillers. But which form of pain manag...
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 ...
People smoke marijuana in water pipes, bongs, hand rolled cigarettes or even mix it with food which are called edibles. 1. THC is an extract from marijuana which is dangerous for people. a) THC acts on specific brain cells which makes the person hallucinate and have abnormal brain behavior and function. 2.
The human body produces naturally occurring cannabinoids. The cannabinoids are lipophilic. Delta-8 and Delta-9 Tetrahydrocannabinol (THC) have been found to produce most of the psychoactive effects of marijuana (Carter et al., 2003). Delta-9 Tetrahydrocannabinol appears to be the most abundant cannabinoid and the main source of cannabis' impact. Cannabidiol is
Marijuana is a public name for an illegal substance (drug) produced from the Cannabis (Cannabis sativa) plant. It is also called weed, ganja, grass, kaya and pot. The drug has many chemical compounds and in particular, it has THC (delta-9-tetrahydrocannabinol) which is responsible for changing mind functions leading to alternations of cognition, mood, behavior, perception and consciousness. “It is the most widely used illicit substance in the world” (World, 2010, p. 198). Its usage includes religious, medicinal, recreational and spiritual purposes. In the beginning of the 20th century, in most countries marijuana was illegalized.
First off it is important to understand the effects of cannabis use and its history. When smoking cannabis THC is the leading stimulant released.
Also, there is no quality control on marijuana that is circulating on the street. Due to the diverse strains of marijuana, each individual may have a different, possibly adverse response to the drug. “Andrea Barthwell, MD, former Deputy Director at the U.S. Office of National Drug Control Policy (ONDCP), told an audience on Jan. 26, 2005: ‘[I]n the 1970s and 80s, the active ingredient in marijuana, THC, was at 3.5 percent. Today, the THC found in most marijuana averages more than 7 percent. But specific techniques can skyrocket the amount of THC to as high as 27 percent.... ...
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.
...ause of the psychoactive ingredient THC can cause paranoia and seizures. The CBD in marijuana may have many medical benefits but until more dispensaries reduce the amount of THC, it is still questionable weather some patients should use marijuana as a medicine. Marijuana can cause damage to premature developing brains and should be tested in a lab before giving to children.
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 marijuana 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.
Marijuana is an extremely popular drug, not only in America, but in every other country in the world as well. However, there are many people who do not know exactly what it is or where it comes from. Marijuana is a blend of flowers, seeds, leaves, and stems from the Indian hemp planted called Cannabis. This plant contains a chemical called tetrahydrocannabinol (THC), which causes the “high” feeling that users experience when smoking it (“Marijuana: Effects, Medical Uses & Legalization”). The THC in marijuana is analogous to the nicotine in tobacco, but it is not as harmful. They both have many similarities, but they also have significant differences.
2. Marijuana is a product of the hemp plant and contains the chemical THC that is the most potent of over 400 chemicals found in marijuana and mainly affects the brain.
