In the earlier days, usage of Cannabis (majorly known as Marijuana) was chiefly marginalized to cigarettes. It never occurred to any sane mind to use it as a medical drug. But, it happened later on as more avenues of medical research confirmed its usage as medical drug. According to 67% of American doctors are in the favor of using it as a medical option. 33%, on the other side, are staunch opponents to use it as a medical drug.
Surely, the opposing opinions of opponents carry weight not to use Cannabis as a medical option. But, some facts are written below which distinguish the difference to take Cannabis as a medical option and cannabinoids as disease carrying agents in different disease. The people fall prey to diseases because of its crude use and spewing fume out of unrefined cigarettes. In the diseases like nausea, vomiting, cancer chemotherapy, anorexia and cachexia in HIV/AIDS, chronic, especially neuropathic pain, spasticity in multiple sclerosis and spinal cord injury there is strong evidence for medical benefits. In other brain cognitive diseases like epilepsy, pruritus and depressions of various kinds, a large amount of data is available and the research is steadying on these issues.
There are universally accepted 23 healthy benefits of Marijuana. Two of which are listed below:
Marijuana use can be used to treat and prevent the eye disease glaucoma, which is the causal of pressure increase in eyeball, damaging the optic nerve and causing loss of vision. Marijuana decreases the pressure inside the eye, according to the National Eye Institute of United States of America: "Studies in the early 1970s showed that marijuana, when smoked, lowered intraocular pressure (IOP) in people with normal pressure and those with glaucoma." These effects of the drug may slow the progression of the disease, preventing blindness.
It is strange and seems suddenly out of blue that Cannabis may help the carcinogenic effects of tobacco and improve lung health but the explanation below completely is in unison with the claim:
“According to a study published in Journal of the American Institute in January 2012, marijuana does not impair lung function and can even increase lung capacity. Researchers looking for risk factors of heart disease tested the lung function of 5,115 young adults over the course of 20 years. Tobacco smokers lost lung function over time, but pot users actually showed an increase in lung capacity. It is possible that the increased lung capacity may be due to taking deep breaths while inhaling the drug and not from a therapeutic chemical in the drug.”
These are the benefits of using Cannabis as a medical drug. But, it has a darker aspect as well. Many people get addicted to it. They hamper themselves socially, mentally, physically, economically and cognitively. They become aloof from society and their loved ones. Its excessive use may lead towards Schizophrenia, Alzheimer and other memory loss disease. But, as it has medical viability so it should be used for human welfare by restricting it positively to medical research only.
