Several animal studies have led researchers to believe that cannabis could reverse signs of aging in the brain. Aging mice treated with small daily doses of THC showed a reversal in cognitive decline. However, past studies on the effects of cannabis on human memory show less promising results. Still, with few viable treatments for dementia, medical marijuana is receiving increased attention in this area.
Hemp paper are paper varieties consisting exclusively or to a large extent from pulp obtained from fibers of industrial hemp. The products are mainly specialty papers such as cigarette paper, banknotes and technical filter papers. Compared to wood pulp, hemp pulp offers a four to five times longer fibre, a significantly lower lignin fraction as well as a higher tear resistance and tensile strength. However, production costs are about four times higher than for paper from wood, so hemp paper could not be used for mass applications as printing, writing and packaging paper.
Fig. 5. Typical architecture of categories of cultivated Cannabis sativa. Top left: narcotic plants are generally low, highly branched, and grown well-spaced. Top right: plants grown for oilseed were traditionally well-spaced, and the plants developed medium height and strong branching. Bottom left: fiber cultivars are grown at high density, and are unbranched and very tall. Bottom center: “dual purpose” plants are grown at moderate density, tend to be slightly branched and of medium to tall height. Bottom right: some recent oilseed cultivars are grown at moderate density and are short and relatively unbranched. Degree of branching and height are determined both by the density of the plants and their genetic background.
Short-term use of the drug impairs thinking and coordination. In long-term studies, teens who smoke marijuana have lower IQs later on, as well as structural differences in their brains, though scientists debate whether this is an effect of the drug or a result of habitual pot smokers seeking out less intellectually stimulating pursuits. A 2016 study on almost 300 students by the University of Montreal published in the journal Development and Psychopathology found that teens who start smoking around age 14 do worse on some cognitive tests by age 20 than non-smokers. They also have a higher school dropout rate. If they wait until age 17 to start, though, the smokers do not seem to have the same impairments, according to the study.
Hi…I read your statement about hemp being a cream that takes pain away. Living in Oregon there’s no talk about “hemp” but I don’t doubt your experience with it..and I’m wondering where you found it..so that maybe I can get a jar of it and see if it would help my aches and pains….I would really appreciate your response…and thanks for your “reply” that motivated me to write to you..
In Japan, hemp was historically used as paper and a fiber crop. There is archaeological evidence cannabis was used for clothing and the seeds were eaten in Japan back to the Jōmon period (10,000 to 300 BC). Many Kimono designs portray hemp, or asa (Japanese: 麻), as a beautiful plant. In 1948, marijuana was restricted as a narcotic drug. The ban on marijuana imposed by the United States authorities was alien to Japanese culture, as the drug had never been widely used in Japan before. Though these laws against marijuana are some of the world's strictest, allowing five years imprisonment for possession of the drug, they exempt hemp growers, whose crop is used to make robes for Buddhist monks and loincloths for Sumo wrestlers. Because marijuana use in Japan has doubled in the past decade, these exemptions have recently been called into question.
“DEA will continue to support sound and scientific research that promotes legitimate therapeutic uses for FDA-approved constituent components of cannabis, consistent with federal law,” acting DEA administrator Uttam Dhillon said in a press release. “DEA is committed to continuing to work with our federal partners to seek ways to make the process for research more efficient and effective.”
Cannabis, also known as marijuana among other names,[a] is a psychoactive drug from the Cannabis plant used for medical or recreational purposes. The main psychoactive part of cannabis is tetrahydrocannabinol (THC), one of 483 known compounds in the plant, including at least 65 other cannabinoids. Cannabis can be used by smoking, vaporizing, within food, or as an extract.
Medical cannabis, or medical marijuana, can refer to the use of cannabis and its cannabinoids to treat disease or improve symptoms; however, there is no single agreed-upon definition. The rigorous scientific study of cannabis as a medicine has been hampered by production restrictions and other federal regulations. There is limited evidence suggesting cannabis can be used to reduce nausea and vomiting during chemotherapy, to improve appetite in people with HIV/AIDS, and to treat chronic pain and muscle spasms. Its use for other medical applications is insufficient for conclusions about safety or efficacy.
Hemp seeds can be eaten raw, ground into hemp meal, sprouted or made into dried sprout powder. Hemp seeds can also be made into a liquid and used for baking or for beverages such as hemp milk and tisanes. Hemp oil is cold-pressed from the seed and is high in unsaturated fatty acids. The leaves of the hemp plant, while not as nutritional as the seeds, are edible and can be consumed raw as leafy vegetables in salads, and pressed to make juice.
Although global abnormalities in white matter and grey matter are not associated with cannabis abuse, reduced hippocampal volume is consistently found. Amygdalar abnormalities are sometimes reported, although findings are inconsistent. Preliminary evidence suggests that this effect is largely mediated by THC, and that CBD may even have a protective effect.

^ Juliet Eilperin (February 11, 2013), "'Good seed' versus 'evil weed': Hemp activists eye legalization", The Washington Post – via The Japan Times Online, [A] couple of factors — the high taxes the federal government imposed on growing hemp in the late 1930s and again in the early '50s, and then the DEA's interpretation of the 1970 law — made producing hemp nearly impossible. Since the DEA only grants permits in rare instances and demands costly, elaborate security precautions, large-scale hemp growing in the United States is not viable.
