The plant was first given its taxonomic identification by Carl Linnaeus in 1753 and thoroughly described to Westerners in the 1800s, when the medical doctor William O'Shaughnessy gave a report to the Medical and Physical Society of Calcutta in India in 1839. The doctor described its effects on people and did a few case reports on "gunjah," the Indian name for the drug.
There is great variation in Cannabis sativa, because of disruptive domestication for fiber, oilseed, and narcotic resin, and there are features that tend to distinguish these three cultigens (cultivated phases) from each other. Moreover, density of cultivation is used to accentuate certain architectural features. Figure 5 illustrates the divergent appearances of the basic agronomic categories of Cannabis in typical field configurations.
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.[112][113][114] Preliminary evidence suggests that this effect is largely mediated by THC, and that CBD may even have a protective effect.[115]

Laboratory evidence indicated that cannabidiol may reduce THC clearance, increasing plasma concentrations which may raise THC availability to receptors and enhance its effect in a dose-dependent manner.[24][25] In vitro, cannabidiol inhibited receptors affecting the activity of voltage-dependent sodium and potassium channels, which may affect neural activity.[26] A small clinical trial reported that CBD partially inhibited the CYP2C-catalyzed hydroxylation of THC to 11-OH-THC.[27]


The relationship between THC and CBD is complex, but in short, CBD appears to minimize some of THC’s undesirable effects, such as paranoia, heart palpitations, and impaired thinking. Compared with THC in isolation, or its synthetic cousins such as Marinol, the combination of THC and CBD has much greater therapeutic value to patients. This phenomenon of cannabis-derived molecules working better together than they do in isolation is commonly referred to as the entourage effect.
I have a 2.5 yr old boxer pit mix who I adopted from the shelter with auto immune problems. She suffers from anything like skin rashes to elevated liver to allergies and swelling of her little toes 🙁 What do you recommend? I don’t mind spending the money to help her be comfortable …any advice would help as I have never given her anything like this 🙂

When THC is consumed, it binds to CB1 receptors in the brain, which is what causes users to get high, while still providing certain health benefits. But CBD does not directly bind to these receptors and instead indirectly interacts with the CB2 receptors that are found mainly in the immune system, though they (along with CB1 receptors) are also found throughout the body.
Cannabidiol (CBD) is a naturally occurring compound found in the resinous flower of cannabis, a plant with a rich history as a medicine going back thousands of years. Today the therapeutic properties of CBD are being tested and confirmed by scientists and doctors around the world. A safe, non-addictive substance, CBD is one of more than a hundred “phytocannabinoids,” which are unique to cannabis and endow the plant with its robust therapeutic profile.
Quality is a particular concern, because cannabis plants easily soak up heavy metals from pesticides and other contaminants, Marcu says. If you are buying online, look for a company that documents how it tests its products. (If the website doesn’t indicate this, call and ask.) “Buying from a reputable manufacturer is crucial, because it matters how the plant is cultivated and processed,” Dr. Maroon says. One clue that a company is cutting corners: too low a cost. Good CBD is pricey—a bottle of high-quality capsules is sold in Cohen’s office for $140. But for many, it’s worth the money. Roth spent $60 on her tiny bottle. But when her energy returned the day she started taking CBD, she decided that was a small price to pay.
I have had chronic pain in my back neuroma in my foot my SI joint. I have had my share of medication. If youve ever had any pain relentless you know what a miserable existence it is. I was at the end of my rope seriously considering cutting off my toe having almost crippling pain from discs and muscles in my back. My husband thought CBD could be a good solution since Id previously had a CBD edible and it helped me through tattoo pain. He went hunting for CBD and just happened to find this lotion. Its been a game changer. I have been able to gain mobility all but erased the pain from my back and has helped me in conjunction with a nerve blocker for my foot. This lotion really does change my life. I call it magic. I am so happy with it.

Whole-plant or full-spectrum extracts are considered to be the most therapeutically effective. In this form, CBD works in conjunction with other cannabinoids to produce what’s called the entourage effect: the result of numerous types of cannabinoids, each with a specific function, working together. You’ll sometimes see THC in the mix as well; aside from its recreational aspects, it has its own set of medicinal properties and can be particularly effective against severe pain.
Henry Ford recognized the utility of hemp in early times. In advance of today’s automobile manufacturers, he constructed a car with certain components made of resin stiffened with hemp fiber (Fig. 19). Rather ironically in view of today’s parallel situation, Henry Ford’s hemp innovations in the 1920s occurred at a time of crisis for American farms, later to intensify with the depression. The need to produce new industrial markets for farm products led to a broad movement for scientific research in agriculture that came to be labeled “Farm Chemurgy,” that today is embodied in chemical applications of crop constituents.

Cannabis has held sacred status in several religions. It has been used in an entheogenic context – a chemical substance used in a religious, shamanic, or spiritual context[59] - in the Indian subcontinent since the Vedic period dating back to approximately 1500 BCE, but perhaps as far back as 2000 BCE. There are several references in Greek mythology to a powerful drug that eliminated anguish and sorrow. Herodotus wrote about early ceremonial practices by the Scythians, thought to have occurred from the 5th to 2nd century BCE. In modern culture the spiritual use of cannabis has been spread by the disciples of the Rastafari movement who use cannabis as a sacrament and as an aid to meditation. The earliest known reports regarding the sacred status of cannabis in the Indian subcontinent come from the Atharva Veda estimated to have been written sometime around 2000–1400 BCE.[60]

Cannabis impairs psychomotor performance in a wide variety of tasks, such as motor coordination, divided attention, and operative tasks of many types; human performance on complex machinery can be impaired for as long as 24 hours after smoking as little as 20 mg of THC in cannabis; there is an increased risk of motor vehicle accidents among persons who drive when intoxicated by cannabis.

People are always looking for all natural ways to improve their wellness, and this is what CBD can offer. There are a lot of ailments that CBD can help treat, and it is also dubbed as an all-around cure because of how it alleviates most symptoms from the body. It is safe to say that there are a lot of undiscovered benefits when it comes to CBD and its uses.
Because of its high THC-content, in most parts of the world, including the US, Marijuana is illegal. Seeing the massive economical and medicinal benefits that Marijuana can provide, some countries and states in the US have legalized Marijuana. As the political landscape changes, hopefully more will follow, but as of now, Marijuana is generally illegal.
From the 1950s to the 1980s, the Soviet Union was the world's largest producer of hemp (3,000 square kilometres (1,200 sq mi) in 1970). The main production areas were in Ukraine,[87] the Kursk and Orel regions of Russia, and near the Polish border. Since its inception in 1931, the Hemp Breeding Department at the Institute of Bast Crops in Hlukhiv (Glukhov), Ukraine, has been one of the world's largest centers for developing new hemp varieties, focusing on improving fiber quality, per-hectare yields, and low THC content.[88][89]
Cannabis for industrial uses is valuable in tens of thousands of commercial products, especially as fibre[107] ranging from paper, cordage, construction material and textiles in general, to clothing. Hemp is stronger and longer-lasting than cotton. It also is a useful source of foodstuffs (hemp milk, hemp seed, hemp oil) and biofuels. Hemp has been used by many civilizations, from China to Europe (and later North America) during the last 12,000 years.[107][108] In modern times novel applications and improvements have been explored with modest commercial success.[109][110]
Historically, so many different applications have been found for hemp’s stalk. In a 1938 Popular Mechanics article, hemp was stated to be the next ‘billion dollar crop’, as it praised its bafflingly strong fibers. The magazine found there to be more than 25,000 industrial uses for hemp. Applications of hemp stalk include apparel, bags, rope, netting, canvas, and carpet.
Although it is a cannabinoid, CBD does not directly interact with the two classical cannabinoid receptors (CB1 and CB2).  Instead, it affects signaling through CB1 and CB2 receptors indirectly. This partly explains why, in contrast to THC, CBD is non-intoxicating. In addition to its indirect influence on the CB1 and CB2 receptors, CBD can increase levels of the body’s own naturally-produced cannabinoids (known as endocannabinoids) by inhibiting the enzymes that break them down.
The black-market purchases were 8% lower than in the third quarter, the first to follow full legalization of cannabis for adult recreational use on Oct. 17. On a percentage basis, illegal sales accounted for 79% of the overall market, down from 90% in the third quarter, the data showed. The development of the legal market was hampered by shortages of product after many provinces underestimated demand.
Regardless of production hurdles, the beauty of this kind of bioengineering is that it gives researchers a powerful platform to dig into not just what each cannabinoid might be useful for—whether treating anxiety or inflammation or epilepsy—but how the many cannabinoids in the plant might interact with one another. This is known as the entourage effect: CBD, for instance, seems to attenuate the psychoactive effects of THC.
There's no question that CBD is the buzzy wellness product of the moment. If you live in a state where it's currently legal, you might feel like CBD has gone from being sort of around to absolutely everywhere all at once. Coffee shops sell CBD lattes, spas offer CBD facials, beauty companies are rushing to release lotions with CBD or hemp oils in their formulas. And everyone from your anxious coworker to your arthritis-suffering dad wants to get their hands on some CBD gummies.
Part of the mystery around cannabis and animals is because of the fact cannabis is still federally illegal, so there hasn’t been funding or legal access to cannabis for potential projects. Without that research, the American Veterinary Medical Association can’t state that vets are allowed to even discuss cannabis as a possible recommended medication without risking their medical license. That being said, they released a document to members in February of this year titled “Cannabis: What Veterinarians Need to Know” to help doctors “advise clients and treat patients who may have been exposed to marijuana.”
In the mid 1990s, the EU provided subsidization for hemp cultivation of ca. $1,050/ha. This support was instrumental in developing a hemp industry in western Europe. However, no comparable support is available in North America, and indeed those contemplating entering into hemp cultivation are faced with extraordinary costs and/or requirements in connection with licensing, security, THC analysis, and record keeping. Those involved in value-added processing and distribution are also faced with legal uncertainties and the regular threat of idiosyncratic, indeed irrational actions of various governments. Simply displaying a C. sativa leaf on advertising has led to the threat of criminal charges in the last decade in several G8 countries. Attempting to export or import hemp products among countries is presently a most uncertain activity.
Donald Abrams was a member of the committee that reviewed the evidence that went into producing the report, and he said that the studies they reviewed overwhelmingly used pharmaceutically available preparations that contain THC, including dronabinol, nabilone and the whole-plant extract spray nabiximols, which contains equal parts CBD and THC. It’s impossible to know whether the benefits of cannabis can also be obtained from CBD alone, Abrams said, because CBD is just one of 400 chemicals present in the plant. So far, CBD in isolation has been studied in only a handful of randomized, placebo-controlled trials (considered the gold standard of evidence in medical research), and the evidence remains sparse.
In the meantime, some physicians are forging ahead — and cashing in. Joe Cohen is a doctor at Holos Health, a medical marijuana clinic in Boulder. I asked him what CBD is good for, and he read me a long list of conditions: pain, inflammation, nausea, vomiting, intestinal cramping, anxiety, psychosis, muscle spasms, hyperactive immune systems, nervous system degeneration, elevated blood sugar and more. He also claimed that CBD has anti-cancer properties and can regenerate brain cells and reduce the brain’s levels of amyloid beta — a kind of protein that’s been linked to Alzheimer’s disease. I asked for references, noting that most of these weren’t listed in the Academies report or a similar review published in the Journal of the American Medical Association. “I think you just have to Google search it,” he said. It’s true that a preliminary study found hints that cannabinoids might reduce beta amyloid proteins in human brain cells, but the study was done in cells grown in a lab, not in people. As for cancer, the FDA sent warning letters last year to four companies that were selling products that claimed to “prevent, diagnose, treat or cure” cancer.
