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.
Because C. sativa has been a neglected crop for so long in North America, there are only negligible genetic resources available on this continent. Most germplasm stocks of hemp are in Europe, and the largest and most important collection is the Vavilov Institute gene bank in Leningrad. Figure 11 shows THC concentrations in the Vavilov collection, as well as in our own collection, largely of European germplasm. A disturbingly high percentage of the collections have THC levels higher than 0.3%, making it difficult to incorporate these into breeding programs.
Hemp, (Cannabis sativa), also called industrial hemp, plant of the family Cannabaceae cultivated for its fibre (bast fibre) or its edible seeds. Hemp is sometimes confused with the cannabis plants that serve as sources of the drug marijuana and the drug preparation hashish. Although all three products—hemp, marijuana, and hashish—contain tetrahydrocannabinol (THC), a compound that produces psychoactive effects in humans, the variety of cannabis cultivated for hemp has only small amounts of THC relative to that grown for the production of marijuana or hashish.
Acute effects may include anxiety and panic, impaired attention, and memory (while intoxicated), an increased risk of psychotic symptoms, and possibly an increased risk of accidents if a person drives a motor vehicle while intoxicated. Short-term cannabis intoxication can hinder the mental processes of organizing and collecting thoughts. This condition is known as temporal disintegration. Psychotic episodes are well-documented and typically resolve within minutes or hours. There have been few reports of symptoms lasting longer.
What makes CBD so appealing is that it’s non-intoxicating, so it won’t get you high, though it “is technically psychoactive, because it can influence things like anxiety,” Jikomes said. Although much of the marketing blitz around CBD centers on the fact that you can take it without getting stoned, there isn’t much research looking at the effects of CBD when used in isolation, with a couple of exceptions. One is the use of CBD to treat seizures: CBD is the active ingredient in the only cannabis product that the Food and Drug Administration has signed off on — a drug called Epidiolex, which is approved for treating two rare forms of epilepsy. Animal models and a few human studies suggest that CBD can help with anxiety, but those are the only conditions with much research on CBD in isolation.

It’s easy to see why vaping has become such a popular method for consuming marijuana. The method is remarkably discrete and produces none of the telltale “weed smells” that often betray cannabis users. Vape pens and other hand-held devices are portable and convenient. They’re free of many of the harsh marijuana plant compounds that can harm your lung health, like tars. And companies are getting better at crafting high-quality, flavorful vape cartridges with a wide array of cannabinoid profiles.
Known for invigorating and uplifting sensations, with a high focus in the mind rather than the body, sativas are extremely popular as daytime-use strains and for social occasions. Sativas are also widely associated with the cerebral and creativity-enhancing effects of weed. Hence, they are lauded by artists and other inventive people who use cannabis.
Among the company’s many offerings is Real Scientific Hemp Oil, which it sells through its subsidiary HempMedsPx, also based in Poway. On its web site, HempMedsPx describes how its hemp “is grown in northern European microclimates, without the use of any pesticides, herbicides or chemical fertilizers.” The company promises that it “continuously scrutinizes and improves the processes to meet all regulations and exceeds quality standards.”
This guide is an introduction to anyone looking to inform themselves about the reality of cannabis. It covers basic information about the marijuana plant, cannabis preparations, and the crucial elements of plant anatomy and science. This guide to marijuana also gives an overview of the most popular medical and recreational uses of cannabis. It offers a survey of the most important medical cannabis research while highlighting emerging trends in the legal cannabis market. The guide also introduces those new to cannabis to the many ways to consume marijuana, and much more.
Cannabis has an ancient history of ritual use and is found in pharmacological cults around the world. Hemp seeds discovered by archaeologists at Pazyryk suggest early ceremonial practices like eating by the Scythians occurred during the 5th to 2nd century BC, confirming previous historical reports by Herodotus. It was used by Muslims in various Sufi orders as early as the Mamluk period, for example by the Qalandars. Smoking pipes uncovered in Ethiopia and carbon-dated to around c. AD 1320 were found to have traces of cannabis.
There are many varieties of cannabis infusions owing to the variety of non-volatile solvents used. The plant material is mixed with the solvent and then pressed and filtered to express the oils of the plant into the solvent. Examples of solvents used in this process are cocoa butter, dairy butter, cooking oil, glycerine, and skin moisturizers. Depending on the solvent, these may be used in cannabis foods or applied topically.
I discovered in my research that hemp is really legal in all 50 states so I guess this must be a very complicated thing. It may be likely some states are allowed to grow it and others aren’t, I don’t know but all I know is somewhere in my research it said it was legal in all 50 states. Anyway, I got my oil on auto delivery, I really need to start using it in my food a little more often to help with certain health issues including but not limited to arthritis pain 😇👍
In the Australian states of Tasmania, Victoria, Queensland, and most recently, New South Wales, the state governments have issued licences to grow hemp for industrial use. The first to initiate modern research into the potential of cannabis was the state of Tasmania, which pioneered the licensing of hemp during the early 1990s. The state of Victoria was an early adopter in 1998, and has reissued the regulation in 2008.
The 2014 US Farm Bill allows states that have passed their own industrial hemp legislation to grow industrial hemp for purposes of research and development. Several states — including Kentucky, Colorado, and Oregon — are already conducting hemp pilot projects. Many other states are currently pursuing similar legislation and programs. After many years of prohibition, American farmers are finally reacquainting themselves with industrial hemp.
Along with its better-known counterpart, THC (delta-9-tetrahydrocannabinol, the chemical that produces the marijuana high), CBD is one of more than 400 compounds found in the oils of cannabis plant species, which include marijuana and hemp. Unlike THC, CBD will not make you high. That said, this doesn’t mean CBD is not at all psychoactive, as many assert, says Jahan Marcu, Ph.D., director of experimental pharmacology and behavior at the International Research Center on Cannabis and Mental Health in New York City: “CBD does change cognition. It affects mood, which is why people take it for anxiety. And some find that it makes them more alert.”

Hi, I had ovarian cancer stage 2 and went to do chemotherapy for 16 times in 2014. It came back last year 2016 but I did not do chemotherapy or radiation therapy as suggested by the doctor. I am taking hormone therapy at the moment. I would like to use cannabis oil but which one and how much CBD and how much THC should I take for ovarian cancer? Can anyone give some idea?. Thank you very much.
“Hemp is of high nutritional quality because it contains high amounts of unsaturated fatty acids… Linoleic acid and alpha-linolenic acid are the only two fatty acids that must be ingested and are considered essential to human health … In contrast to shorter-chain and more saturated fatty acids, these essential fatty acids do not serve as energy sources, but as raw materials for cell structure and as precursors for biosynthesis for many of the body’s regulatory biochemicals…”
