Medical marijuana is a term used to refer to the unprocessed marijuana extracts or plant. It is a plant that can be used in treating either the symptoms of a disease or other conditions. In 2737 BC, the Chinese emperor Shen Nung writing states cannabis was first used as a psychoactive agent. In this writing cannabis had power against, malaria, gout, rheumatism as well as absent mindedness. The medical value importance was centered more than its intoxication properties. Eventual the use of cannabis spread also to India then parts of North Africa and later in AD500 to Europe. From 1850 to 1942 medical marijuana has been listed among the Pharmacopeia in the U.S. it was used for various medical conditions such as nausea, rheumatism as well as labor pain (Pacula and Smart 66). This paper is entirely based on the medical marijuana benefits based on the scientific evidences and researches done in various parts of the world and documented.Medical UsesFrom 1850 till 1930 cannabis began to be common for recreational reasons and purposes. While the uses of this medical marijuana increased in the 1970 Control Substance Act, was categorized as a Scheduled I Drug. Later, the natural marijuana medical use controversy arouse. The THC active ingredient was synthesized in the laboratory in 1966 and the United States Food and Drug Administration approved it early 1985 (Pacula and Smart 66).The Institute of Medicine disclosed in the 1999 United States Government Sponsored study the medical marijuana benefits in some medical issues such as wasting resulting from, AIDs and nausea resulting from the chemotherapy drugs. From 1999 numerous researches have revealed that marijuana that is smoked has the pain reducing properties. Numerous researches and scientific studies have revealed many other medical benefits of marijuana (Pacula and Smart 66).Marijuana Stops or Slows the Spread of Cancer CellsIn a study published in a Molecular Cancer Therapeutics journal, it explains that Cannabis has the capability of stopping cancer through turning off the Id-1 gene. In 2007, the California Pacific Medical Center found in San Francisco researchers, reported that cannabis can prevent the spreading of the cancer cells. These researchers did a test on breast cancer that contained high Id-1 levels in the laboratory. They treated this breast with cannabidiol. The results were positive. They showed a decrease in the Id-1 expression in the cells and the spreading of these cancerous cells. The American Association for Cancer Research in fact found that marijuana has the ability to slow down the growth of cancer cells or tumors in the breast, lungs and brain considerately. Therefore, medical marijuana has the benefit and property of suppressing the Id-1 expression as well as preventing the spread of the cancerous cells in the body (Abrams 66).Prevents Alzheimer’s DiseaseThe active agent, THC, in medical marijuana slows Alzheimer’s disease progression in a study that was conducted by the research institute. In this research, it was found that THC slows amyloid plaques formation. It blocks the enzyme in the human brain that results in Alzheimer’s disease formation. The plaques are the ones that destroy the cells of the brain resulting into Alzheimer’s disease. Therefore, medical marijuana has the ability to stop the development of this plaque (Collins and Workman 44).Treats GlaucomaCannabis has the ability of treating any type of glaucoma. Glaucoma causes eyeball pressure to increase thus damaging nerves as well as resulting in vision loss. The National Eye Institute states that medical marijuana aids in lowering the pressure in the eyes (Gieringer, and Gregory 67). 1970s studies revealed that smoking medical marijuana resulted in decreases intraocular pressure (IOP) in both individual with glaucoma as well as normal eye pressure. These impacts of the drugs prevents blindness.Relieves ArthritisA research conducted in 2011 indicated that marijuana reduces inflammation, pain as well as promotes sleep. These properties of cannabis can aid in relieving discomfort and pain for individual having rheumatoid arthritis. For instance, the rheumatology units researchers in many hospital gave Sativex, a cannabinoid-based-pain- reliving drug to their patients. After fourteen days, patients on this drug had a considerably pain reduction effect as well as slept well more than the patients who were using Placebo drug. Therefore, it is evident that medical marijuana has a medical benefit in reducing pain and promoting sleep on the rheumatoid arthritis patients (Gieringer, and Gregory 67).Controls Epileptic SeizuresA study that was done in 2003 indicated that medical marijuana had the ability of controlling epileptic seizure. For instance, Robert J. DeLerenzo from Virginia University injected epileptic rats with synthetic marijuana and marijuana extract. This drugs controlled epileptic for around ten hours. It was discovered that the active agent in marijuana, THC, controlled seizures through binding all cell of the brain that are in charge of regulating relaxation and controlling excitability. The Pharmacology and Experimental Therapeutics journal published this results indicating that medical marijuana has potential of controlling epileptic seizures in patients (Hill 56).Eases the Multiple Sclerosis PainMedical marijuana stops negative neurological impacts as well as muscle spasms resulting from multiple sclerosis. The Canadian Medical Association study reported that marijuana can ease multiple sclerosis painful symptoms. For example, a study was done on thirty patients suffering from multiple sclerosis having painful muscle contraction. The patient were not improving from this condition even after taking medication. However after smirking this marijuana for some days, they said that the pain had decreased. Therefore, the marijuana active agent, THC, bonds the receptors in nerves as well as muscles to dismiss pain.Soothes Tremors for Parkinson’s Diseases PatientsIn a research that was conducted in Israel, smoking marijuana pains. It extraordinarily reduces tremors and pain. Medical marijuana as well promotes sleep in patients with Parkinson’s disease. This research proved that medical marijuana improves motor skills within these patients. This made the government of Israel to legalized marijuana usage in medicine (Amar 67).Helps in Crohn’s DiseaseCannabis has the ability of curing Crohn’s disease. Crohn’s disease is a disorder of bowel characterizes by inflammation that causes vomiting, pain, weight loss diarrhea among other symptoms. A current study that was conducted in Israel revealed that smoking a considerable amount of medical marijuana results in reduction of the symptoms of Crohn’s disease in the 10 out of 11 victims. At the same time, marijuana causes a complete termination of this disease In 5 of those victims. At the same time the cannabinoids gotten from cannabis appear to aid in controlling the gut bacteria as well as intestinal functions.Decreases the Dravet’s Syndrome SymptomsSevere developmental as well as seizure are caused by Dravet’s Syndrome. For instance, a young girl with Dravet’s Syndrome was treated with marijuana. After some days of treatment the seizures reduced from three hundred per week to one in every week. Other 40 children as well used the drug and it aided them as well. The doctors say that cannabidiol in marijuana plant interacts with the cell of the brain to silence the unnecessary activities in the human brain that result in seizures.Lessens Side Impacts from Hepatitis C Treatment and Increases Effectiveness of TreatmentHepatitis C treatment has several side effect that are very severe. This side effect make many people to opt their withdrawal. This side effects ranges from muscle pains, nausea, appetite loss, depression as well as fatigue. This side effects last for many months. A study done in 2006 by the Gastroenterology and Hepatology realized that 86 percent of the patients who were using marijuana finished the therapies successful. On the other hand only 29 percent of the non-smoking patients finished the treatment (Hill 56). Similarly, 54 percent of those using marijuana got their levels of viral low as well as kept them low compared to the non-smokers who were only 8 percent with this characteristics. Therefore, marijuana helps in reducing the side effects of Hepatitis C treatment as well as improves the effectiveness of its treatment.Decreases AnxietyHarvard University researchers in 1010 suggested that medical marijuana can reduces anxiety. This property enables this drug to be used as a sedative when used in low doses. However, high doses of medical marijuana can lead to increased anxiety. Therefore the low doses aid in medical field in sedating as well as reducing the patient anxiety.Helps Reverse the Tobacco Carcinogen Effect As Well As Improve the Health of the LungsThe American Medical Association in January of 2012 showed that medical marijuana has the ability of improving the functions of the lung as well as increasing its capacity. For example, a research that was done in search of the heart diseases risks found coincidentally that children who were using marijuana had an increased lung capacity compared to the ones who were using tobacco. However some researcher say that the increase of lung capacity is a result of deep breathing when inhaling and not the treatment properties of medical marijuana.Reducing the Severe Pain As Well As Nausea from Chemotherapy and Stimulates AppetitePeople undergoing chemotherapy are recommended to use marijuana. Patients undergoing chemotherapy experience severe pains, vomiting, and loss of appetite as well as painful nausea. The THC agent in marijuana can aid in counteracting this side effects from chemotherapy. It reduces pain, stirs up appetite and decreases nausea. Likewise, FDA has approved other cannabinoids medications that uses the THC for similar reasons.Improves Lupus Symptoms, an Autoimmune DisorderSystemic Lupus is treated by use of marijuana. Lupus is a disease whereby the body attacks its cells for reasons that are not known. The various chemical present in marijuana aid in calming the immune system down. This property aids the body to deal with Lupus symptoms. Other benefits of marijuana on lupus symptoms result from its ability to reduce pain as well as nausea.Protects the Brain after StrokeThe University of Nottingham research (that was done on mice, monkey, and rats) showed that marijuana may aid protect the brain from injury that a stroke causes. The cannabis reduces the size of the region that is affected by a stroke. Other researchers have provided evidence of marijuana protecting the cell of the brain from even traumatic incidences such as concussion (Hill 56). Therefore, marijuana has the medical potential of protecting the cells of the brain from the traumatic events or even a stroke.Controls Varies Kinds of Muscle SpasmMuscle spasm of different types as well respond to marijuana. For instance, a patient having Myoclonus Diaphragmatic Flutter or Leeuwenhoek’s Disease used marijuana that aided in calming the attacks. Leewenhoek’s diseases causes a continuous spasm in the muscles of the abdomen. This spasm causes pain and interferes with speaking and taking. Various strong medication have no positive effect against this activities. Therefore, marijuana calms this attacks immediately causing the diaphragmatic muscles to relax.Helps in Eliminating NightmaresMarijuana has the ability to alter the sleep cycle. It interferes with the rapid eye movement (REM) sleep later stages. This is helpful especially for night mare victims or PTSD patients. Nightmares occur during this later staged of REM sleep. The active agencies such as THC have evidently reduced the frequency of nightmares in PTSD patients. Therefore, marijuana aids in preventing nightmares in various patients. However, it has also some negative effect when used for this purpose on patient and thus more research need to be done (Hill 56).Protects the Brain from Trauma and ConcussionA study in the Cerebral Cortex journal explains that marijuana can aid heal the brain cells after trauma or concussion. For example, an experiment that was done on a rat marijuana reduced the brain bruising. It also aided with the mechanism of healing after an injury that resulted from trauma. A psychology professor in Harvard wrote that the national football league should stopping marijuana tests on the players since it aids in traumatic injury healing process. Doctors believes that a dose of marijuana has very high neuro-protective properties and thus has medical benefit (Pacula and Smart 66).ConclusionIn conclusion medical marijuana has numerous benefits. It is medical benefits are the most amazing ones. It is a plant that has active agents that aids in treating various medical conditions. Marijuana has the ability to treat Alzheimer’s disease, protect the brain from concussion, nightmares and muscle spasm. Not only these conditions but also Lupus Symptoms, Dravet’s Syndrome, Glaucoma, Multiple Sclerosis Pain, Crohn’s disease, Parkinson’s Diseases and Reducing the severe pain as well as nausea from chemotherapy and stimulates appetite. Even though the United States Food and Drugs Administration has neither recognized nor approved the use of marijuana plant as a drug in hospital, it has medical benefits (Pacula and Smart 69). The scientific studies of a chemical component in marijuana known as cannabinoid has shown it is potential medicinal uses. The Food and Drugs Administration Food has approved the drugs containing the cannabinoid in form of pills. As many research have proved, marijuana has many other medicine benefits.ReferencesAbrams, Donald I. “Using Medical Cannabis in an Oncology Practice.” Oncology, vol. 30, no. 5, 2016, pp. 397–397.It explains on how cannabis can suppress the cancerous cells starting from breast cancer to other complex cancers like brain cancer.Amar, Mohamed Ben. “Cannabinoids in Medicine: A Review of Their Therapeutic Potential.” Journal of Ethno pharmacology, vol. 105, no. 1–2, 2006, pp. 1–25.It explains on the potential uses of medical marijuana in treatment.Collins, Ian, and Paul Workman. “New Approaches to Molecular Cancer Therapeutics.” Nature Chemical Biology, vol. 2, no. 12, 2006, p. 689.Gieringer, Dale H, Ed Rosenthal, and Gregory T.
