Cannabis contains a seemingly unique class of chemicals, the cannabinoids, of which more than 60 have been described, but only a few are psychoactive. Cannabinoids are produced in specialized epidermal glands, which differ notably in distribution on different organs of the plant (high concentrations occur on the upper surface of the young leaves and young twigs, on the tepals, stamens, and especially on the perigonal bract). Given this distribution, the glands would seem to be protective of young and reproductive above-ground tissues (the roots lack glands). Two classes of epidermal glands occur—stalked and sessile (Fig. 8), but in either case the glandular cells are covered by a sheath under which resin is accumulated, until the sheath ruptures, releasing resin on the surface. The resin is a sticky mixture of cannabinoids and a variety of terpenes. The characteristic odor of the plant is due to the abundant terpenes, which are not psychoactive. The more important cannabinoids are shown in Fig. 9. In the plant the cannabinoids exist predominantly in the form of carboxylic acids, which decarboxylate with time or when heated. Delta-9-tetrahydrocannabinol (D9-THC, or simply THC) is the predominant psychoactive component. Other THC isomers also occur, particularly D8-THC, which is also psychoactive. Technically, the euphoric psychological effects of THC are best described by the word psychotomimetic. Cannabidiol (CBD) is the chief non-psychotomimetic cannabinoid. A THC concentration in marijuana of approximately 0.9% has been suggested as a practical minimum level to achieve the (illegal) intoxicant effect, but CBD (the predominant cannabinoid of fiber and oilseed varieties) antagonizes (i.e. reduces) the effects of THC (Grotenhermen and Karus 1998). Concentrations of 0.3% to 0.9% are considered to have “only a small drug potential” (Grotenhermen and Karus 1998). Some cannabinoid races have been described, notably containing cannabichromene (particularly in high-THC forms) and cannabigerol monomethyl ether (in some Asian strains). The biosynthetic pathways of the cannabinoids are not yet satisfactorily elucidated, although the scheme shown in Fig. 10 is commonly accepted. At least in some strains, THC is derived from cannabigerol, while in others it may be derived from CBD. CBN and D8-THC are considered to be degradation products or analytical artifacts (Pate 1998a).
My dad has severe advanced stage Dementia. Will CBD oil help him at this point? He is now refusing to eat any solid food, but will accept most drinks.In addition, he has lost a great deal of weight even though they're giving him Mega Shakes containing a full meals worth of proteins, etc. He gets at least 4 of these a day..some which he refuses. Is his Dementia too far gone for CBD oils to help him?
Hemp jewelry is the product of knotting hemp twine through the practice of macramé. Hemp jewellery includes bracelets, necklaces, anklets, rings, watches and other adornments. Some jewellery features beads made from crystals, glass, stone, wood and bones. The hemp twine varies in thickness and comes in a variety of colors. There are many different stitches used to create hemp jewellery, however, the half knot and full knot stitches are most common.
Because cannabinoid receptors, unlike opioid receptors, are not located in the brainstem areas controlling respiration, lethal overdoses from Cannabis and cannabinoids do not occur.[1-4] However, cannabinoid receptors are present in other tissues throughout the body, not just in the central nervous system, and adverse effects include tachycardia, hypotension, conjunctival injection, bronchodilation, muscle relaxation, and decreased gastrointestinal motility.

The word cannabis is from Greek κάνναβις (kánnabis) (see Latin cannabis),[134] which was originally Scythian or Thracian.[135] It is related to the Persian kanab, the English canvas and possibly even to the English hemp (Old English hænep).[135] In modern Hebrew, קַנַּבּוֹס‬ qannabōs (modern pronunciation: [kanaˈbos]) is used but there are those who have theorized that it was referred to in antiquity as קני בושם q'nei bosem, a component of the biblical anointing oil.[136][137] Old Akkadian qunnabtu, Neo-Assyrian and Neo-Babylonian qunnabu were used to refer to the plant meaning "a way to produce smoke".[138][139][140]

As a result of intensive selection in cultivation, Cannabis exhibits many sexual phenotypes that can be described in terms of the ratio of female to male flowers occurring in the individual, or typical in the cultivar.[27] Dioecious varieties are preferred for drug production, where the female flowers are used. Dioecious varieties are also preferred for textile fiber production, whereas monoecious varieties are preferred for pulp and paper production. It has been suggested that the presence of monoecy can be used to differentiate licit crops of monoecious hemp from illicit drug crops.[21] However, sativa strains often produce monoecious individuals, probably as a result of inbreeding.

There is some speculation that George Washington smoked the flower of the cannabis plant in order to achieve a recreational high ("Like all farmers, Washington probably sampled the quality and potency of what he grew, and he may have used this hemp to treat his chronic tooth aches"),[53] but there is no evidence in any of his writings that he grew hemp for anything other than industrial purposes. It is sometimes supposed that an excerpt from Washington's diary, which reads "Began to seperate [sic] the Male from the Female hemp at Do.&—rather too late" is evidence that he was trying to grow female plants for the THC found in the flowers. However, the editorial remark accompanying the diary states that "This may arise from their [the male] being coarser, and the stalks larger"[115] In subsequent days, he describes soaking the hemp[116] (to make the fibers usable) and harvesting the seeds,[117] suggesting that he was growing hemp for industrial purposes, not recreational.
A rather thorough analysis of the scope of the illicit marijuana industry in Canada for 1998 is reported at and summarized in MacLeod (1999). At least 800 tonnes (t) of marijuana were grown in Canada in 1998, representing a harvest of 4.7 million flowering plants. More than 50% of the marijuana available in Canada is grown domestically. An average mature plant was estimated to produce 170 g of “marketable substance.” The value of the Canadian crop is uncertain, but has been estimated to be in the billions of dollars annually (Heading 1998; MacLeod 1999).
Nevertheless, every bit of this ancient plant is useful and valuable, and not just for rope, but for textiles, auto parts, cosmetics, dynamite, supplements, food, and medicine. In ancient China, hemp seed was regarded as food for the lower classes, and in Europe, a peanut butter-like spread was made from the seeds, in both cases with the hulls intact.
The applicant, including all corporate officers, must be fingerprinted at a law enforcement agency. The law enforcement agency, not the applicant, must send the fingerprint sheet to the Department (80-18-103, MCA). Most local law enforcement offices provide fingerprinting services. The completed application and copy of the law enforcement submitted fingerprints will be submitted for DEA review and approval. The DEA may place additional requirements on the Department or the applicant for participation or continuation of the program. At the end of the licensure, program participants must submit an agricultural/agronomic report regarding their experience with their hemp crop. The report shall include the approximate yield in pounds per acre and the method used to devitalize the seed. All seed must be devitalized after harvest and no seed production for future planting is allowed under the Montana Industrial Hemp Pilot Program.

Hemp was made illegal to grow without a permit in the U.S. under the Controlled Substances Act passed in 1970 because of its relation to marijuana,[17] and any imported hemp products must meet a zero tolerance level.[87] Some states have made the cultivation of industrial hemp legal, but farmers in many states have not yet begun to grow it because of resistance from the federal Drug Enforcement Administration,[88] making "large-scale hemp growing" in the United States "not viable" as late as 2013.[89] In 2013, after the legalization of cannabis in the state, several farmers in Colorado planted and harvested several acres of hemp, bringing in the first hemp crop in the United States in over half a century.[90] Colorado,[91] Vermont, California, and North Dakota have passed laws enabling hemp licensure. All four states are waiting for permission to grow hemp from the DEA. Currently,[92] Oregon has licensed industrial hemp as of August 2009.[93] Congress included a provision in the Agricultural Act of 2014 that allowed colleges and state agencies to grow and conduct research on hemp in states where it is legal.[17] Hemp production in Kentucky, formerly the United States' leading producer, resumed in 2014.[94] Hemp production in North Carolina resumed in 2017,[95] and in Washington State the same year.[96] By the end of 2017, at least 34 U.S. states had industrial hemp programs.[97] In 2018, New York began taking strides in industrial hemp production, along with hemp research pilot programs at Cornell University, Binghamton University and SUNY Morrisville.[98]
Beckerman also urged supporters of hemp (and of its danker cousin) to be more vigilant than ever about federal and state-level law and policy moves going forward. “Special interests and residual hysteria will continue to try to get in there, to stomp on the little guy, and on consumer rights and safety, and to over-regulate, so it’s more important than ever that we organize and engage,” she said.
The Spaniards brought hemp to the Americas and cultivated it in Chile starting about 1545.[110] Similar attempts were made in Peru, Colombia, and Mexico, but only in Chile did the crop find success.[111] In July 1605, Samuel Champlain reported the use of grass and hemp clothing by the (Wampanoag) people of Cape Cod and the (Nauset) people of Plymouth Bay told him they harvested hemp in their region where it grew wild to a height of 4 to 5 ft. [112] In May 1607, "hempe" was among the crops Gabriel Archer observed being cultivated by the natives at the main Powhatan village, where Richmond, Virginia is now situated;[113] and in 1613, Samuell Argall reported wild hemp "better than that in England" growing along the shores of the upper Potomac. As early as 1619, the first Virginia House of Burgesses passed an Act requiring all planters in Virginia to sow "both English and Indian" hemp on their plantations.[114] The Puritans are first known to have cultivated hemp in New England in 1645.[110]
...with due respect, your experience Locsta is almost precisely what happened with my....chihuahua. Degenerative disc disease, excruciating pain, prednisone worked, but couldn't keep her on it..pain killers and muscle relaxants didn't help, really thought I would have to put her down. Chi bloggers suggested CBD; gave PetReleaf a shot--like you, literally within minutes I could see the difference, in days she was pain free and now is back in charge of our world. The real key here is that with my dog, there is zero, nada, chance that there was any placebo effect...

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.

Many animal studies have previously demonstrated that delta-9-THC and other cannabinoids have a stimulatory effect on appetite and increase food intake. It is believed that the endogenous cannabinoid system may serve as a regulator of feeding behavior. The endogenous cannabinoid anandamide potently enhances appetite in mice.[39] Moreover, CB1 receptors in the hypothalamus may be involved in the motivational or reward aspects of eating.[40]
I have/had ovarian/primary peritoneal cancer. I used thc/cbd oil pills I self made from the start. I am supposedly their “poster child”. I went thru with chemo and surgery. Oh that horror! But when I tried to tell two seperate doctors, the surgeon was all about it, and my oncologist threw a fit and said it was an anecdote. There are more than 100 studies at the NIH govt website.

But recent activity in Washington has legislators in every aisle waving banners for hemp. So far, 20 states have stepped up to encourage industrial hemp production.5 On February 7, 2014, the 2013 Farm Bill6 was signed into law, legitimizing industrial hemp as distinct, and authorizing university and State departments of agriculture (where it’s legal) for research or pilot programs. On January 8, 2015, The Industrial Hemp Farming Act of 2015, S. 134, was introduced in the U.S. Senate. 
Participants must pay the $400 fee to receive industrial hemp seed through the DEA approved pilot program. Applicants must secure seed orders from DEA approved international seed suppliers. The department will work with the seed suppliers to secure import and export permits to have the seed delivered to the department. Seed costs and shipping are not included in the fee.
Stephanie, generally, I have patients take 20 to 150mg a day for sleep +/- anxiety. Start low and go slow. Know the dosages of your product. Usually 2/3 to 3/4 of the daily dose is 1-2 hours before bedtime, and the other portion is upon waking (to improve wakefulness during the day). Other factors such as stress, hormone replacement, other meds & medical conditions, etc. play a role along with individual differences. I own a compounding pharmacy, so we see a lot of unique needs. I can't give more specific advice in this forum, but there is help!

exhaustion and pain that kept her on the couch much of the day. The 58-year-old Seattle speech coach didn’t want to take opioid pain-killers, but Tylenol wasn’t helping enough. Roth was intrigued when women in her online chat group enthused about a cannabis-derived oil called cannabidiol (CBD) that they said relieved pain without making them high. So Roth, who hadn’t smoked weed since college but lived in a state where cannabis was legal, walked into a dispensary and bought a CBD tincture. “Within a few hours of placing the drops in my mouth, the malaise and achiness that had plagued me for weeks lifted and became much more manageable,” she says. She took the drops several times a day and in a few weeks was back to her regular life.
Textile expert Elizabeth Wayland Barber summarizes the historical evidence that Cannabis sativa, "grew and was known in the Neolithic period all across the northern latitudes, from Europe (Germany, Switzerland, Austria, Romania, Ukraine) to East Asia (Tibet and China)," but, "textile use of Cannabis sativa does not surface for certain in the West until relatively late, namely the Iron Age."[107] "I strongly suspect, however, that what catapulted hemp to sudden fame and fortune as a cultigen and caused it to spread rapidly westwards in the first millennium B.C. was the spread of the habit of pot-smoking from somewhere in south-central Asia, where the drug-bearing variety of the plant originally occurred. The linguistic evidence strongly supports this theory, both as to time and direction of spread and as to cause."[108]
Hemp paper is high-priced for several reasons. Economies of scale are such that the supply of hemp is minute compared to the supply of wood fiber. Hemp processing requires non-wood-based processing facilities. Hemp paper is typically made only from bast fibers, which require separation from the hurds, thereby increasing costs. This represents less than 50% of the possible fiber yield of the plant, and future technologies that pulp the whole stalks could decrease costs substantially. Hemp is harvested once a year, so that it needs to be stored to feed mills throughout the year. Hemp stalks are very bulky, requiring much handling and storage. Transportation costs are also very much higher for hemp stalks than for wood chips. Waste straw is widely available from cereals and other crops, and although generally not nearly as desirable as hemp, can produce bulk pulp far more cheaply than can be made from hemp. In addition to agricultural wastes, there are vast quantities of scrub trees, especially poplar, in northern areas, that can supply large amounts of low-quality wood fiber extremely cheaply. Moreover, in northern areas fast-growing poplars and willows can be grown, and such agro-forestry can be very productive and environmentally benign. And, directly or indirectly, the lumber/paper industry receives subsidies and/or supports, which is most unlikely for hemp.

The following sketch of hemp cultivation is insufficient to address all of the practical problems that are encountered by hemp growers. Bócsa and Karus (1998) is the best overall presentation of hemp growing available in English. The reader is warned that this book, as well as almost all of the literature on hemp, is very much more concerned with fiber production than oilseed production. McPartland et al. (2000) is the best presentation available on diseases and pests, which fortunately under most circumstances do limited damage. The resource list presented below should be consulted by those wishing to learn about hemp production. Provincial agronomists in Canada now have experience with hemp, and can make local recommendations. Particularly good web documents are: for Ontario (OMAFRA Hemp Series, several documents):; for Manitoba (several documents):; for British Columbia: (BC Ministry of Agriculture and Foods Fact Sheet on Industrial Hemp, prepared by A. Oliver and H. Joynt):
If you decide to cut back or stop after using cannabis regularly, you may experience psychological and physical withdrawal symptoms such as irritability, sleep difficulty, vivid dreams, and decreased appetite. Talk to a trusted friend or family member about your plan to change, and ask them to look out for and support you. Alternatively, call Alcohol and Drug Helpline 0800 787 797 for confidential, non-judgmental advice and referral to a local service provider.

Marijuana or marihuana (herbal cannabis),[157] consists of the dried flowers and subtending leaves and stems of the female Cannabis plant.[158][159][160][161] This is the most widely consumed form,[161] containing 3% to 20% THC,[162] with reports of up-to 33% THC.[163] This is the stock material from which all other preparations are derived. Although herbal cannabis and industrial hemp derive from the same species and contain the psychoactive component (THC), they are distinct strains with unique biochemical compositions and uses. Hemp has lower concentrations of THC and higher concentrations of CBD, which decreases the psychoactive effects[164][165]
Let's start with the most officially proven medical use of CBD. Earlier this year, the FDA approved the first-ever drug containing CBD, Epidiolex, to treat two rare forms of pediatric epilepsy. To get to that point, the drug's manufacturers had to do a whole lot of randomized, placebo-controlled trials on humans. They had to study how much children could take, what would happen in case of overdose, and any possible side effects that would occur.

In the United States, cannabis is overall the number four value crop, and is number one or two in many states including California, New York and Florida, averaging $3,000 per pound ($6,600/kg).[244][245] Some believe it generates an estimated $36 billion market.[246] Some have argued that this estimate is methodologically flawed, and makes unrealistic assumptions about the level of marijuana consumption. Other estimates claiming to correct for this flaw claim that the market is between $2.1-$4.3 billion.[237] The United Nations Office on Drugs and Crime claims in its 2008 World Drug Report that typical U.S. retail prices are $10–15 per gram (approximately $280–420 per ounce). Street prices in North America are known to range from about $40–$400 per ounce ($1.4–$14/g), depending on quality.[247]
Three controlled trials demonstrated that oral THC has variable effects on appetite stimulation and weight loss in patients with advanced malignancies and human immunodeficiency virus (HIV) infection.[32] One study evaluated the efficacy of dronabinol alone or with megestrol acetate compared with that of megestrol acetate alone for managing cancer-associated anorexia.[40] In this randomized, double-blind study of 469 adults with advanced cancer and weight loss, patients received 2.5 mg of oral THC twice daily, 800 mg of oral megestrol daily, or both. Appetite increased by 75% in the megestrol group and weight increased by 11%, compared with a 49% increase in appetite and a 3% increase in weight in the oral THC group after 8 to 11 weeks of treatment. These two differences were statistically significant. Furthermore, the combined therapy did not offer additional benefits beyond those provided by megestrol acetate alone. The authors concluded that dronabinol did little to promote appetite or weight gain in advanced cancer patients compared with megestrol acetate. However, a smaller, placebo-controlled trial of dronabinol in cancer patients demonstrated improved and enhanced chemosensory perception in the cannabinoid group—food tasted better, appetite increased, and the proportion of calories consumed as protein was greater than in the placebo recipients.[41]

During the period from 1937 to the late 60s, the U.S. government understood and acknowledged that industrial hemp and marijuana were distinct varieties of the Cannabis plant. Hemp was no longer officially recognized as distinct from marijuana after the passage of the Controlled Substances Act (CSA) of 1970. This is despite the fact that a specific exemption for hemp was included in the CSA under the definition of marijuana. The recent federal court case HIA vs DEA has re-established acknowledgement of distinct varieties of Cannabis, and supports the exemption for non-viable seed and fiber and any products made from them.

Over the ages, countless innovations have attempted to improve on the basic experience of inhaling the smoke of combusted cannabis. As a result, there are numerous ways to smoke marijuana. The rolling technique is at the root of joints, blunts, and spliffs. On the other hand, glassware and other devices are essential for smoking weed out of a pipe, bong, or bubbler.

My mother has dementia/Alzheimers along with a broken knee that they will not repair do to her mental status. She is currently in a nursing home. I firmly believe her mental situation began with the over use of hydrocodone for over 30 years and was acerbated by the trauma of breaking and disconnecting her knee cap. Since weaning her off of her meds (still in progress) we have regained much of her consciousness. I want to try CBD to help in her recovery or to help slow down the disease. I cannot find a dosage recommendation plus the nursing home/doctor does not recommend it. I would need to give it to her when I am there visiting (about 3 - 4 times per week). Is there a recommended dosage for dementia/Alzheimers?

Hemp can be used as a "mop crop" to clear impurities out of wastewater, such as sewage effluent, excessive phosphorus from chicken litter, or other unwanted substances or chemicals. Additionally, hemp is being used to clean contaminants at the Chernobyl nuclear disaster site, by way of a process which is known as phytoremediation—the process of clearing radioisotopes and a variety of other toxins from the soil, water, and air.[44]
