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.[190] It was used by Muslims in various Sufi orders as early as the Mamluk period, for example by the Qalandars.[191] Smoking pipes uncovered in Ethiopia and carbon-dated to around c. AD 1320 were found to have traces of cannabis.[192]
State legislatures have taken action to promote industrial hemp as an agricultural commodity in recent years. A wide range of products, including fibers, textiles, paper, construction and insulation materials, cosmetic products, animal feed, food, and beverages all may use hemp. The plant is estimated to be used in more than 25,000 products spanning nine markets: agriculture, textiles, recycling, automotive, furniture, food/nutrition/beverages, paper, construction materials and personal care.
The question of whether heteromorphic sex chromosomes are indeed present is most conveniently answered if such chromosomes were clearly visible in a karyotype. Cannabis was one of the first plant species to be karyotyped; however, this was in a period when karyotype preparation was primitive by modern standards (see History of Cytogenetics). Heteromorphic sex chromosomes were reported to occur in staminate individuals of dioecious "Kentucky" hemp, but were not found in pistillate individuals of the same variety. Dioecious "Kentucky" hemp was assumed to use an XY mechanism. Heterosomes were not observed in analyzed individuals of monoecious "Kentucky" hemp, nor in an unidentified German cultivar. These varieties were assumed to have sex chromosome composition XX.[31] According to other researchers, no modern karyotype of Cannabis had been published as of 1996.[32] Proponents of the XY system state that Y chromosome is slightly larger than the X, but difficult to differentiate cytologically.[33]
"Skunk" refers to several named strains of potent cannabis, grown through selective breeding and sometimes hydroponics. It is a cross-breed of Cannabis sativa and C. indica (although other strains of this mix exist in abundance). Skunk cannabis potency ranges usually from 6% to 15% and rarely as high as 20%. The average THC level in coffee shops in the Netherlands is about 18–19%.[242]

Marijuana is the most popular illicit drug in the world, for no reason other than the fact that it produces a psychoactive chemical called tetrahydrocannabinol. Still, recreational marijuana use, which involves pursuing the euphoric sensations produced by cannabis consumption, is steadily becoming more and more legal, both in the United States and abroad.
CBD Oil, derived from agricultural hemp, has been widely recognized for its many benefits on human health. It has grown in popularity amongst the medical community as a key supplement for maintaining homeostasis. Because CBD oil has the ability to talk to nearly every organ system in the body via the Endocannabinoid System (ECS) this plant-based nutrient plays a key role in optimizing balance and enhancing quality of life.
In recent years, a wide range of synthetic products, claiming to have similar effects to cannabis, have also been available in Australia. Synthetic cannabis is made up of chemicals that are designed to activate the same chemical systems in the brain as THC. These drugs are marketed as having similar physical and psychological effects as cannabis, but can have more unpredictable effects and are potentially more harmful than cannabis.
Some users may experience an episode of acute psychosis, which usually abates after six hours, but in rare instances, heavy users may find the symptoms continuing for many days.[52] A reduced quality of life is associated with heavy cannabis use, although the relationship is inconsistent and weaker than for tobacco and other substances.[53] It is unclear, however, if the relationship is cause and effect.[53]

An industrial hemp license issued by the state provides authorization for the production of industrial hemp at a particular growing area by a particular individual or entity. Licenses will expire on the last day of December of the year that they are issued. Renewals do not require new fingerprinting unless the department requests it or if the corporate officers have changed.

While basic attentional and working memory abilities are largely restored, the most enduring and detectable deficits are seen in decision-making, concept formation and planning.
Will hemp commercial cultivation resume in the US in the foreseeable future? This is difficult to judge, but the following considerations suggest this might occur: (1) increasing awareness of the differences between industrial hemp and marijuana; (2) growing appreciation of the environmental benefits of hemp cultivation; (3) continuing demonstration of successful hemp cultivation and development in most of the remaining western world; all the G8 countries, except the US, produce and export industrial hemp; and (4) increasing pressure on state and federal governments to permit hemp cultivation by farmers, particularly wheat, corn, and tobacco farmers in desperate need of substitute crops, but also for rotation crops to break pest and disease cycles.
Grown and extracted from the USA, our quality CBD is fully compliant under the Kentucky Department of Agricultural Industrial Hemp Pilot Program. Our CBD products are legal and shipped to all 50 states and internationally. All of our CBD products contain 0% THC, guaranteed. We utilize a whole plant CO2 extraction that allows us to draw the CBD from the plant material and filter out unnatural substances, maximizing pure CBD concentration. Each and every product that leaves the facility is third-party tested to ensure consistency and quality.
Cannabis, also referred to as marijuana, has been an integral part of human civilizations for millennia. Both as a medicine and as a recreational substance, cannabis is the most popular illicit drug in the world. Today, the legal landscape that has prohibited marijuana for much of the twentieth century is giving way to decriminalization and full legalization. Legal, commercial cannabis businesses are already making an enormous economic impact.

Selective breeding of cannabis plants has expanded and diversified as commercial and therapeutic markets develop. Some growers in the U.S. succeeded in lowering the proportion of CBD-to-THC to accommodate customers who preferred varietals that were more mind-altering due to the higher THC and lower CBD content.[58] Hemp is classified as any part of the cannabis plant containing no more than 0.3% THC in dry weight form (not liquid or extracted form).[59]

Harvesting tall varieties for grain is difficult. In France, the principal grower of dual-purpose varieties, the grain is taken off the field first, leaving most of the stalks for later harvest (Fig. 49). Putting tall whole plants through a conventional combine results in the straw winding around moving parts, and the fibers working into bearings, causing breakdown, fires, high maintenance, and frustration. Following the French example of raising the cutting blade to harvest the grain is advisable. Growing short varieties dedicated to grain production eliminates many of the above problems, and since the profitability of hemp straw is limited at present, seems preferable. Grain growers should be aware that flocks of voracious birds are a considerable source of damage to hempseed, particularly in small plantations.


Hemp does best on a loose, well-aerated loam soil with high fertility and abundant organic matter. Well-drained clay soils can be used, but poorly-drained clay soils are very inappropriate because of their susceptibility to compaction, which is not tolerated. Young plants are sensitive to wet or flooded soils, so that hemp must have porous, friable, well-drained soils. Sandy soils will grow good hemp, provided that adequate irrigation and fertilization are provided, but doing so generally makes production uneconomical. Seedbed preparation requires considerable effort. Fall plowing is recommended, followed by careful preparation of a seedbed in the spring. The seedbed should be fine, level, and firm. Seed is best planted at 2–3 cm (twice as deep will be tolerated). Although the seedlings will germinate and survive at temperatures just above freezing, soil temperatures of 8°–10°C are preferable. Generally hemp should be planted after danger of hard freezes, and slightly before the planting date of maize. Good soil moisture is necessary for seed germination, and plenty of rainfall is needed for good growth, especially during the first 6 weeks. Seeding rate is specific to each variety, and this information should be sought from the supplier. Fiber strains are typically sown at a minimum rate of 250 seeds per m2 (approximately 45 kg/ha), and up to three times this density is sometimes recommended. In western Europe, seeding rates range from 60–70 kg/ha for fiber cultivars. Recommendations for seeding rates for grain production vary widely, from 10–45 kg/ha. Densities for seed production for tall, European, dual-purpose cultivars are less than for short oilseed cultivars. Low plant densities, as commonly found in growing tall European cultivars for seed, may not suppress weed growth adequately, and under these circumstances resort to herbicides may pose a problem for those wishing to grow hempseed organically. Hemp requires about the same fertility as a high-yielding crop of wheat. Industrial hemp grows well in areas that corn produces high yields. Growing hemp may require addition of up to 110 kg/ha of nitrogen, and 40–90 kg/ha of potash. Hemp particularly requires good nitrogen fertilization, more so for seed production than fiber. Adding nitrogen when it is not necessary is deleterious to fiber production, so that knowledge of the fertility of soils being used is very important. Organic matter is preferably over 3.5%, phosphorus should be medium to high (>40 ppm), potassium should be medium to high (>250 ppm), sulfur good (>5,000 ppm), and calcium not in excess (<6,000 ppm).
Another concern is about medications with which CBD might interact. This won’t be an issue with most drugs, says Sunil Kumar Aggarwal, M.D., Ph.D., a palliative medicine physician and scientist who studies cannabis and integrates it into his Seattle medical practice. The exceptions are blood thinners, IV antibiotics, and other drugs whose exact dosing is crucial and must be monitored closely, he says. (Of course, if you have a health problem, talk to your doctor before using CBD, and never take it instead of seeing your physician for a serious condition.)
I don’t know a whole lot about the plants but a friend of mine who did weed told me hamper is just the stem of the cannabis. He would know, I wouldn’t. Sadly though he died June 10 of 2018 of stage 4 lung cancer. He was a heavy smoker and I just couldn’t be around it despite our best efforts to set up a ventilation system to fan the smoke out. I must be allergic to secondhand smoke though because I keep getting bronchitis every time I’m exposed to it for long enough and it doesn’t really take a real long time even under the best conditions. Second hand weed smoke really didn’t help either, with me smoke a smoke and I just can’t be around it as it becomes a serious issue. I’m still struggling with trying to get the junk out of my respiratory system that keeps building up in the very upper part of it
Then came World War II. The Japanese attack on Pearl Harbor shut off foreign supplies of "manila hemp" fiber from the Philippines. The USDA produced a film called "Hemp For Victory" to encourage U.S. farmers to grow hemp for the war effort. The U.S. government formed the War Hemp Industries Department and subsidized hemp cultivation. During the war, U.S. farmers grew about a million acres of hemp across the Midwest as part of that program.
Cannabis Ruderalis – Thought to be a cannabis species originating in central Asia, it flowers earlier, is much smaller, and can withstand much harsher climates than either Cannabis indica or Cannabis sativa. This species purportedly buds based on age rather than changes in length of daylight, known as auto-flowering. It’s used primarily for food production, such as hemp seeds and hemp seed oil.
Hemp is plagued by bird predation, which take a heavy toll on seed production. The seeds are well known to provide extremely nutritious food for both wild birds and domestic fowl. Hunters and birdwatchers who discover wild patches of hemp often keep this information secret, knowing that the area will be a magnet for birds in the fall when seed maturation occurs. Increasingly in North America, plants are being established to provide habitat and food for wildlife. Hemp is not an aggressive weed, and certainly has great potential for being used as a wildlife plant. Of course, current conditions forbid such usage in North America.
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.

Marijuana has in fact been grown for medicinal research in North America by both the Canadian (Fig. 40) and American governments, and this will likely continue. The possibility of marijuana becoming a legal commercial crop in North America is, to say the least, unlikely in the foreseeable future. Nevertheless the private sector is currently producing medicinal marijuana in Europe and Canada, so the following orientation to marijuana as a potential authorized crop is not merely academic.
Governor Jeff Colyer, M.D. signed Senate Bill 263 on April 20, which enacts the Alternative Crop Research Act allowing the Kansas Department of Agriculture to oversee the cultivation of industrial hemp in a research program. KDA has begun the process of developing rules and regulations to guide the Alternative Crop Research Act, which included an open dialogue and information exchange at a public forum May 11. Content from that forum is included on this page. 
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.

It is not surprising that male-associated markers are relatively abundant. In dioecious plants where sex chromosomes have not been identified, markers for maleness indicate either the presence of sex chromosomes which have not been distinguished by cytological methods or that the marker is tightly linked to a gene involved in sex determination.[14]
Dehulled (i.e. hulled) hemp seed is a very recent phenomenon, first produced in quantity in Europe. Hemp seeds have been used as food since ancient times, but generally the whole seed, including the hull, was eaten. Hemp seed was a grain used in ancient China, although there has been only minor direct use of hemp seed as food by humans. In the past, hemp seed has generally been a food of the lower classes, or a famine food. Peanut-butter type preparations have been produced from hemp seed in Europe for centuries, but were rather gritty since technology for removing the hulls was rudimentary. Modern seed dehulling using mechanical separation produces a smooth, white, gritless hemp seed meal that needs no additional treatment before it is consumed. It is important to understand, therefore, that the quality of modern hemp seed for human consumption far exceeds anything produced historically. This seed meal should be distinguished from the protein-rich, oil-poor seed cake remaining after oil has been expressed, that is used for livestock feed. The seed cake is also referred to as “seed meal,” and has proven to be excellent for animals (Mustafa et al. 1999).
After the Restoration of Independence in 1640, in order to recover the ailing Portuguese naval fleet, were encouraged its cultivation as the Royal Decree of D. John IV in 1656. At that time its cultivation was carried out in Trás-os-Montes, Zone Tower Moncorvo, more precisely in Vilariça Valley, fertile land for any crop irrigation, and a very large area, flat and very fertile culture still wide until the last century grew up tobacco, a plant that needs a large space to expand and grow, the area lies in the valley of Serra de Bornes.
As in Los Angeles' equity program, the group will offer participants mentorship, job placement, and help with starting businesses in Wisconsin's hemp industry, where close to 220 hemp licenses have already been issued under the current Farm Bill; they also plan to provide on-site housing for participants struggling with homelessness, which often impacts veterans and those recently released from prison.
There are thousands of unique varieties of hemp. The cultivars used for CBD oil contain significantly higher concentrations of CBD than others. Using these uniquely potent plants, it is possible to extract cannabis oil that contains significant levels of cannabidiol, as well as essential vitamins, minerals, fatty acids, terpenes, flavonoids, and other non-psychoactive cannabinoids.

Cannabidiol is insoluble in water but soluble in organic solvents such as pentane. At room temperature, it is a colorless crystalline solid.[45] In strongly basic media and the presence of air, it is oxidized to a quinone.[46] Under acidic conditions it cyclizes to THC.[47] The synthesis of cannabidiol has been accomplished by several research groups.[48][49][50]

Hemp activist and entrepreneur Joy Beckerman, who has spent decades building the US hemp movement, and assists many of the world's leading hemp advocacy and industry groups, said it's still likely that Congress will pass a pro-hemp version of the Farm Bill in the coming months — hopefully without added blows to communities that have been hurt most by nearly a century of cannabis prohibition.


The CBD oil needs to be taken twice a day everyday. The dosage depends on symptoms and it takes 30 days to awken your natural cannabis system after you begin taking the oil. I personally use Hemp works CBD oil in the 750 strength and only need 5 drops sublingual 2 times daily and results are many. Problem with oil and alz.patients is getting them to hold oil under tongue for 60 seconds. We have just began to get my dad on it. He too is in a nursing home in the state of florida and they cannot deny him any medication my mom has requested that he receive. If she is not their they are supposed to administer and she will call them to make sure he gets it. He is not 30 days into dosing yet so I don't have any results to speak of. I do know that since he has started he has had no more bladder infection and has not fallen in 3 weeks. That's a record for him so we will continue to monitor. Best of luck to you and a lot is going to depend on the state your mom is in and what the state laws are concerning her rights or the rights of whom has her medical power of attorney
We also rated the product based on the type of CBD they used: isolate, full-spectrum decarb, broad-spectrum, or distillate. There’s a lot of debate around what is actually best, but our first decision was to give points to CBD oil that contains a range of cannabinoids. While there are certainly people with good reasons for choosing an isolate, there’s a lot of good evidence that CBD works better in combination with other cannabinoids (this is called the “entourage effect”).

This may reflect the multitude of cognitive tasks employed by the various studies included in these meta-analyses, all of which involved performing a task thereby requiring the participant to reorient their attention and attempt to solve the problem at hand and suggest that greater engagement of this region indicates less efficient cognitive performance in cannabis users in general, irrespective of their age.


For many, the medical and therapeutic potential of cannabis is what makes legalizing the marijuana plant such an important political and social task. Federal prohibition has established barriers to comprehensive cannabis research in the United States. However, researchers in other countries continue to make significant contributions to our knowledge of the cannabis plant and how it affects the human body.

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).
Cannabidiol can be taken into the body in multiple different ways, including by inhalation of cannabis smoke or vapor, as an aerosol spray into the cheek, and by mouth. It may be supplied as an oil containing only CBD as the active ingredient (no added THC or terpenes), a full-plant CBD-dominant hemp extract oil, capsules, dried cannabis, or as a prescription liquid solution.[1][3]

She also believes that the Senate's Farm Bill would alleviate confusion caused by the US Drug Enforcement Agency (DEA)'s issuance of conflicting “guidance” to state and federal agencies, which leaves them "scratching their heads," and often "bullies them into making decisions that directly contradict the legislative intent and spirit of the last version of the Farm Bill," Beckerman said.
Based on studies of sex reversal in hemp, it was first reported by K. Hirata in 1924 that an XY sex-determination system is present.[25] At the time, the XY system was the only known system of sex determination. The X:A system was first described in Drosophila spp in 1925.[28] Soon thereafter, Schaffner disputed Hirata's interpretation,[29] and published results from his own studies of sex reversal in hemp, concluding that an X:A system was in use and that furthermore sex was strongly influenced by environmental conditions.[26]

Both in Canada and the US, the most critical problem to be addressed for commercial exploitation of C. sativa is the possible unauthorized drug use of the plant. Indeed, the reason hemp cultivation was made illegal in North America was concern that the hemp crop was a drug menace. The drug potential is, for practical purposes, measured by the presence of THC. THC is the world’s most popular illicit chemical, and indeed the fourth most popular recreational drug, after caffeine, alcohol, and nicotine. “Industrial hemp” is a phrase that has become common to designate hemp used for commercial non-intoxicant purposes. Small and Cronquist (1976) split C. sativa into two subspecies: C. sativa subsp. sativa, with less than 0.3% (dry weight) of THC in the upper (reproductive) part of the plant, and C. sativa subsp. indica (Lam.) E. Small & Cronq. with more than 0.3% THC. This classification has since been adopted in the European Community, Canada, and parts of Australia as a dividing line between cultivars that can be legally cultivated under license and forms that are considered to have too high a drug potential. For a period, 0.3% was also the allowable THC content limit for cultivation of hemp in the Soviet Union. In the US, Drug Enforcement Agency guidelines issued Dec. 7, 1999 expressly allowed products with a THC content of less than 0.3% to enter the US without a license; but subsequently permissible levels have been a source of continuing contention. Marijuana in the illicit market typically has a THC content of 5% to 10% (levels as high as 25% have been reported), and as a point of interest, a current Canadian government experimental medicinal marijuana production contract calls for the production of 6% marijuana. As noted above, a level of about 1% THC is considered the threshold for marijuana to have intoxicating potential, so the 0.3% level is conservative, and some countries (e.g. parts of Australia, Switzerland) have permitted the cultivation of cultivars with higher levels. It should be appreciated that there is considerable variation in THC content in different parts of the plant. THC content increases in the following order: achenes (excluding bracts), roots, large stems, smaller stems, older and larger leaves, younger and smaller leaves, flowers, perigonal bracts covering both the female flowers and fruits. It is well known in the illicit trade how to screen off the more potent fractions of the plant in order to increase THC levels in resultant drug products. Nevertheless, a level of 0.3% THC in the flowering parts of the plant is reflective of material that is too low in intoxicant potential to actually be used practically for illicit production of marijuana or other types of cannabis drugs. Below, the problem of permissible levels of THC in food products made from hempseed is discussed.
In the United States, non-FDA approved CBD products are classified as Schedule I drugs under the Controlled Substances Act.[63] This means that production, distribution, and possession of non-FDA approved CBD products is illegal under federal law. In addition, in 2016 the Drug Enforcement Administration added "marijuana extracts" to the list of Schedule I drugs, which it defined as "an extract containing one or more cannabinoids that has been derived from any plant of the genus Cannabis, other than the separated resin (whether crude or purified) obtained from the plant."[64] Previously, CBD had simply been considered "marijuana", which is a Schedule I drug.[63][65]
Millennia of selective breeding have resulted in varieties that display a wide range of traits; e.g. suited for a particular environments/latitudes, producing different ratios and compositions of terpenoids and cannabinoids (CBD, THC, CBG, CBC, CBN...etc.), fibre quality, oil/seed yield etc. Hemp grown for fiber is planted closely, resulting in tall, slender plants with long fibers.
