As a consumer, you can look at the manufacturer's website to see whether they batch-test their products, or ask them directly. You could also send a sample of your CBD oil to a testing facility yourself, something Bonn-Miller says he would do if he were trying to treat someone with a severe issue such as epilepsy. Testing can also determine whether the product contains pesticides, heavy metals, or other toxins.
Whether the drug and non-drug, cultivated and wild types of Cannabis constitute a single, highly variable species, or the genus is polytypic with more than one species, has been a subject of debate for well over two centuries. This is a contentious issue because there is no universally accepted definition of a species.[53] One widely applied criterion for species recognition is that species are "groups of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups."[54] Populations that are physiologically capable of interbreeding, but morphologically or genetically divergent and isolated by geography or ecology, are sometimes considered to be separate species.[54] Physiological barriers to reproduction are not known to occur within Cannabis, and plants from widely divergent sources are interfertile.[42] However, physical barriers to gene exchange (such as the Himalayan mountain range) might have enabled Cannabis gene pools to diverge before the onset of human intervention, resulting in speciation.[55] It remains controversial whether sufficient morphological and genetic divergence occurs within the genus as a result of geographical or ecological isolation to justify recognition of more than one species.[56][57][58]

For example, the six hemp oil companies the FDA had investigated in February had explicitly advertised CBD products for use in the “cure, mitigation, treatment, or prevention of diseases.” The agency sent warning letters to the companies, ordering them to change their product labeling or face potential legal action. Then, in May, the FDA announced it was excluding products containing cannabidiol from its definition of dietary supplements altogether. Hard, the spokesman for Medical Marijuana, Inc., said the company views “these developments as positive because this allows the debate regarding CBD to come to the forefront.” He characterized the FDA’s May announcement as “an opinion” and added, “Medical Marijuana, Inc. and HempMeds, along with industry associations, are working on determining how we can come to a mutual understanding on the matter with the FDA.”
Thermal Insulation. Thermal insulation products (Fig. 20, 21) are the third most important sector of the hemp industry of the EU. These are in very high demand because of the alarmingly high costs of heating fuels, ecological concerns about conservation of non-renewable resources, and political-strategic concerns about dependence on current sources of oil. This is a market that is growing very fast, and hemp insulation products are increasing in popularity. In Europe, it has been predicted that tens of thousands of tonnes will be sold by 2005, shared between hemp and flax (Karus et al. 2000).
Cannabinoids, terpenoids, and other compounds are secreted by glandular trichomes that occur most abundantly on the floral calyxes and bracts of female plants.[41] As a drug it usually comes in the form of dried flower buds (marijuana), resin (hashish), or various extracts collectively known as hashish oil.[7] In the early 20th century, it became illegal in most of the world to cultivate or possess Cannabis for sale or personal use.
The U.S. hemp-derived CBD market alone is projected to reach $450 million by 2020, and China's cannabis market could grow to 100 billion yuan by 2022 (approximately $14.5 billion). Hemp is already interwoven into the futures of the automotive, construction, energy, environmental mediation and technology industries. Once fully utilized and legal, this plant could impact the global economic positionings of North America, China and Africa.

Cannabis plants produce a unique family of terpeno-phenolic compounds called cannabinoids, some of which produce the "high" which may be experienced from consuming marijuana. There are 483 identifiable chemical constituents known to exist in the cannabis plant,[48] and at least 85 different cannabinoids have been isolated from the plant.[49] The two cannabinoids usually produced in greatest abundance are cannabidiol (CBD) and/or Δ9-tetrahydrocannabinol (THC), but only THC is psychoactive.[50] Since the early 1970s, Cannabis plants have been categorized by their chemical phenotype or "chemotype", based on the overall amount of THC produced, and on the ratio of THC to CBD.[51] Although overall cannabinoid production is influenced by environmental factors, the THC/CBD ratio is genetically determined and remains fixed throughout the life of a plant.[36] Non-drug plants produce relatively low levels of THC and high levels of CBD, while drug plants produce high levels of THC and low levels of CBD. When plants of these two chemotypes cross-pollinate, the plants in the first filial (F1) generation have an intermediate chemotype and produce intermedite amounts of CBD and THC. Female plants of this chemotype may produce enough THC to be utilized for drug production.[51][52]
Some of the research focuses that were explored in 2018 were: comparison of various agronomic factors on industrial hemp (planting dates, tillage regimens, range of soil fertility, etc.); hemp variety comparison for suitability to PA growing conditions; study of the effectiveness of potential herbicide products; comparison of hemp’s capability for weed suppression to other crops; surveying hemp crops for presence of arthropod and disease pests; evaluation of hemp’s performance for phytoremediation and land reclamation; study of hemp seed oil processing and marketability; development of industrial hemp products (using grain, stalks and flowers); genetic selection for desired hemp variety characteristics; and evaluations of hemp as an animal feed ingredient (cattle).  
A population-based case-control study of 611 lung cancer patients revealed that chronic low Cannabis exposure was not associated with an increased risk of lung cancer or other upper aerodigestive tract cancers and found no positive associations with any cancer type (oral, pharyngeal, laryngeal, lung, or esophagus) when adjusting for several confounders, including cigarette smoking.[7]
Low concentrations of CBD aren’t the only concern, either. Cannabis plants are hardy and tough, and their thick stalks possess a special property: bioremediation. When grown in contaminated soil, hemp plants absorb heavy metals and other chemical waste, effectively cleansing the terrain. While all plants absorb some chemicals from the soil, the structure, size, and genetic makeup of hemp make it especially adept at this task. Cannabis is so effective that crops of industrial hemp were planted in the aftermath of the 1986 Chernobyl disaster to help purify heavily irradiated soil. When hemp stalks are used for fiber, paper, and other nonconsumptive industrial purposes, the contaminants absorbed into the plants pose no threat to humans.
CBD is a 5-HT1A receptor agonist, which may also contribute to an anxiolytic effect.[146] This likely means the high concentrations of CBD found in Cannabis indica mitigate the anxiogenic effect of THC significantly.[146] The cannabis industry claims that sativa strains provide a more stimulating psychoactive high while indica strains are more sedating with a body high.[147] However this is disputed by researchers.[148]

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.[38][39] The rigorous scientific study of cannabis as a medicine has been hampered by production restrictions and other federal regulations.[40] 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.[41][42][43] Its use for other medical applications is insufficient for conclusions about safety or efficacy.
Our bodies are thought to produce endocannabinoids by the billions every day. “We always thought the ‘runner’s high’ was due to the release of dopamine and endorphins. But now we know the euphoria is also from an endocannabinoid called anandamide,” its name derived from the Sanskrit word for bliss, says Joseph Maroon, M.D., clinical professor and vice chairman of neurosurgery at the University of Pittsburgh Medical Center. We produce these natural chemicals all day, but they fade quickly because enzymes pop up to destroy them. That’s where CBD comes in: By blocking these enzymes, CBD allows the beneficial compounds to linger. This is why Amanda Oliver, 31, a career consultant in Charleston, SC, pops a CBD gummy bear each night before bed. “I used to lie there tossing and turning as my mind raced from work projects to whether I had set the home alarm,” Oliver says. One piece of candy with 15 mg of CBD is enough to shut off her brain and facilitate sleep. She also swears by the CBD oil she takes at the height of her period, which she says quells her debilitating cramps.

What is cannabis?Cannabis is a drug that comes from Indian hemp plants such as Cannabis sativa and Cannabis indica. The main active chemical in cannabis is THC (delta-9 tetrahydrocannabinol).Cannabis is a depressant drug. Depressant drugs do not necessarily make you feel depressed. Rather, they slow down the activity of the central nervous system and the messages going between the brain and the body. When large doses of cannabis are taken it may also produce hallucinogenic effects.For information on synthetic cannabinoids, see our "Legal high" facts page.Other namesCannabis is also known as grass, pot, hash, weed, reefer, dope, herb, mull, buddha, ganja, joint, stick, buckets, cones, skunk, hydro, yarndi, smoke and hooch.What does cannabis look like?Leaves from the cannabis plant are bright green and have a distinctive shape with five or seven leaflets. The flowering tops and upper leaves are covered in a sticky resin.Cannabis is used for the psychoactive (mind and mood-altering) effects of THC and other active ingredients. THC is the chemical in cannabis that makes you feel “high”.There are three main forms of psychoactive cannabis: marijuana, hashish and hash oil.Marijuana is the most common and least potent form of cannabis. Marijuana is the dried leaves and flowers of the plant.Hashish (“hash”) is dried cannabis resin, usually in the form of a small block. The concentration of THC in hashish is higher than in marijuana, producing stronger effects.Hash oil is a thick, oily liquid, golden brown to black in colour, which is extracted from cannabis. Hash oil is the strongest form of cannabis.How and why is it used?The different forms of cannabis are used in different ways:Marijuana is smoked in hand-rolled cigarettes (joints), or in a pipe (a bong).Hashish is usually added to tobacco and smoked, or baked and eaten in foods such as hash cookies.Hash oil is usually spread on the tip or paper of a cigarette and then smoked.Cannabis and hash can also be smoked in a vaporiser. Vaporisers heat cannabis to temperatures that release its active ingredients while minimising the toxins associated with burning.The THC in cannabis is absorbed into the bloodstream through the walls of the lungs (if smoked), or through the walls of the stomach and intestines (if eaten). The bloodstream carries the THC to the brain, producing the “high” effects. Drugs inhaled get into the bloodstream quicker than those eaten. This means that the effects of cannabis when smoked occur more rapidly than when eaten.Paper and textilesSome species of cannabis have few psychoactive effects. These plants are used to produce hemp fibre for use in paper, textiles and clothing.Medical usesCannabis has been used for medical purposes for many centuries. It has been reported that cannabis may be useful to help conditions such as:nausea and vomiting, particularly when associated with chemotherapywasting and severe weight loss, in people with HIV/AIDS, cancer, or anorexia nervosa, as it may be used as an appetite stimulantpain relief, for example in people with cancer and arthritisrelief from symptoms of some neurological disorders that involve muscle spasms, including multiple sclerosis and spinal cord injuryglaucomaepilepsyasthma.For more information, please click on the Australian Drug Foundation's DrugInfo Clearinghouse web site link below.

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.

It has been contended that hemp is notably superior to most crops in terms of biomass production, but van der Werf (1994b) noted that the annual dry matter yield of hemp (rarely approaching 20 t/ha) is not exceptional compared to maize, beet, or potato. Nevertheless, hemp has been rated on a variety of criteria as one of the best crops available to produce energy in Europe (Biewinga and van der Bijl 1996). Hemp, especially the hurds, can be burned as is or processed into charcoal, methanol, methane, or gasoline through pyrolysis (destructive distillation). As with maize, hemp can also be used to create ethanol. However, hemp for such biomass purposes is a doubtful venture in North America. Conversion of hemp biomass into fuel or alcohol is impractical on this continent, where there are abundant supplies of wood, and energy can be produced relatively cheaply from a variety of sources. Mallik et al. (1990) studied the possibility of using hemp for “biogas” (i.e. methane) production, and concluded that it was unsuitable for this purpose. Pinfold Consulting (1998) concluded that while there may be some potential for hemp biomass fuel near areas where hemp is cultivated, “a fuel ethanol industry is not expected to develop based on hemp.”
During my visit, Penny showed me how she administers Harper’s CBD oils. We stood in her kitchen, where a window opened onto a vista of green grass and a wooden swing set out back. After carefully mixing and measuring Harper’s oils, Penny poured the liquid into a jumbo-sized plastic syringe. “We put this all online,” she told me, referring to the several YouTube videos she has made to help other parents administer hemp oil. Penny leaned down over her daughter to fit the tip of the syringe into her gastronomy tube, and I stood by silently. Harper looked at Penny, and Penny smiled back at her, and eased the plunger down.
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.
In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.

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.
Cannabidiol is currently a class B1 controlled drug in New Zealand under the Misuse of Drugs Act. It is also a prescription medicine under the Medicines Act. In 2017 the rules were changed so that anyone wanting to use it could go to the Health Ministry for approval. Prior to this, the only way to obtain a prescription was to seek the personal approval of the Minister of Health.
Success stories like Oliver’s are everywhere, but there’s not a lot of data to back up those results. That’s because CBD comes from cannabis and, like nearly all other parts of the plant, is categorized by the Drug Enforcement Agency (DEA) as a Schedule 1 drug—the most restrictive classification. (Others on that list: heroin, Ecstasy, and peyote.) This classification, which cannabis advocates have tried for years to change, keeps cannabis-derived products, including CBD, from being properly studied in the U.S.
American industrialists led by newspaper mogul William Randolph Hearst (who owned vast timberlands) and DuPont executives, who’d begun processing petroleum and wood for plastics, became disgruntled by the way hemp cut into their market shares. A 1994 Vegetarian Times article2 describes the group’s devastatingly successful tactics for twisting the public’s perception of hemp:
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]

Today, you’ll find nutty-tasting (hull-less) hemp seeds and their oils baked in breads, cookies, and cakes, blended in smoothies, or tossed into quinoa and pasta dishes, burgers, pizza, vegetables sautés, soups, salads, oatmeal, yogurt, trail mix, and salad dressings. It’s a niche market, with a growing number of specialty outlets due to a growing understanding of this food’s nutritional benefits.
The opportunity to grow a new specialty oilseed crop in Kansas offers potential for diversification for Kansas farmers looking for an alternative crop, or for new farming enterprises interested in cultivating industrial hemp. The Kansas agriculture industry has developed a statewide strategic growth plan in recent years, and is committed to pursuing new and innovative opportunities to grow agriculture. The research generated by participants of this new industrial hemp program will be valuable data in identifying the growth potential offered in this sector.
Marijuana, also called pot, weed, ganja, mary jane, and a host of other nicknames, is made from the Cannabis plant, which has three species: Cannabis sativa; Cannabis indica and Cannabis ruderalis. The flowering plant, which can grow to 16 feet (5 meters) high, likely originated in the Central Asian steppe, near the Altai or Tian Shian Mountains, and was first cultivated in China and India, according to "Cannabis and Cannabinoids: Pharmacology, Toxicology and Therapeutic Potential," (Routledge, 2002).
FDA DISCLOSURE Representations regarding the efficacy and safety of Rosebud CBD have not been evaluated by the Food and Drug Administration. The FDA only evaluates foods and drugs, not supplements like these products. These products are not intended to diagnose, prevent, treat, or cure any disease. Click here (https://www.ncbi.nlm.nih.gov/pubmed/22625422) and here (https://www.ncbi.nlm.nih.gov/pubmed/18728714) to find evidence of a test, analysis, research, or study describing the benefits, performance or efficacy of CBD Oil based on the expertise of relevant professionals. These statements have not been evaluated by the FDA and are not intended to diagnose, treat, or cure any disease. Always check with your physician before starting a new dietary supplement program. The Cannabidiol (CBD) in Rosebud CBD is a natural constituent of industrial hemp plant and grown in the United States of America. Rosebud CBD does not sell or distribute any products that are in violation of the United States Controlled Substances Act (US CSA). All products contain less than 0.3% THC. All products are legal in all 50 states.

That leaves those touting CBD’s effectiveness pointing primarily to research in mice and petri dishes. There, CBD (sometimes combined with small amounts of THC) has shown promise for helping pain, neurological conditions like anxiety and PTSD, and the immune system—and therefore potentially arthritis, diabetes, multiple sclerosis, cancer, and more.
The high lipid-solubility of cannabinoids results in their persisting in the body for long periods of time.[131] Even after a single administration of THC, detectable levels of THC can be found in the body for weeks or longer (depending on the amount administered and the sensitivity of the assessment method).[131] A number of investigators have suggested that this is an important factor in marijuana's effects, perhaps because cannabinoids may accumulate in the body, particularly in the lipid membranes of neurons.[132]
Topicals represent a newer emerging market in medical marijuana products geared toward health and beauty. Cannabinoids can be absorbed through the skin for certain therapeutic benefits without any psychoactivity. Additionally, the essential oils in hemp and cannabis provide many benefits for skin health. From moisturizers to shampoos and deodorants, medical cannabis products continue to diversify.
Ten years ago hemp cultivation was illegal in Germany, England, Canada, Australia, and other countries. Essential to overcoming governmental reluctance in each country was the presentation of an image that was business-oriented, and conservative. The merits of environmentalism have acquired some political support, but unless there is a reasonable possibility that hemp cultivation is perceived as potentially economically viable, there is limited prospect of having anti-hemp laws changed. Strong support from business and farm groups is indispensable; support from pro-marijuana interests and what are perceived of as fringe groups is generally counterproductive. It is a combination of prospective economic benefit coupled with assurance that hemp cultivation will not detrimentally affect the enforcement of marijuana legislation that has led most industrially advanced countries to reverse prohibitions against growing hemp. Should the US permit commercial hemp cultivation to resume, it will likely be for the same reasons.

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.
In December 2013, Uruguay became the first country to legalize growing, sale and use of cannabis.[219] After a long delay in implementing the retail component of the law, in 2017 sixteen pharmacies were authorized to sell cannabis commercially.[220] On June 19, 2018, the Canadian Senate passed a bill and the Prime Minister announced the effective legalization date as October 17, 2018.[37][221] Canada is the second nation to legalize the drug.[222]
Understanding the mechanism of cannabinoid-induced analgesia has been increased through the study of cannabinoid receptors, endocannabinoids, and synthetic agonists and antagonists. Cannabinoids produce analgesia through supraspinal, spinal, and peripheral modes of action, acting on both ascending and descending pain pathways.[41] The CB1 receptor is found in both the central nervous system (CNS) and in peripheral nerve terminals. Similar to opioid receptors, increased levels of the CB1 receptor are found in regions of the brain that regulate nociceptive processing.[42] CB2 receptors, located predominantly in peripheral tissue, exist at very low levels in the CNS. With the development of receptor-specific antagonists, additional information about the roles of the receptors and endogenous cannabinoids in the modulation of pain has been obtained.[43,44]
Every crop grown and every variety may be inspected and sampled by a TDA plant inspector prior to harvest. The grower should contact TDA 30 days prior to harvest for inspection. The license holder is responsible for paying all fees associated with the sample. Each sample is $150. Please keep in mind that the way you set up your production method, may influence the number of samples required to represent the amount of material being produced. Growing multiple varieties will also increase the sampling cost.
Its sturdy fibers have also been put to growing use in high-quality plastics and auto paneling, durable building materials, and other common industrial commodities. And when it comes to environmental impact, hemp is not only a low-fuss crop capable of flourishing in US farmland; it can also clean up tainted water and soil, bully weeds away, and be converted into biodiesel.
Those warning letters aside, there’s not a lot of federal oversight right now over the claims being made or the products that are being sold. Cohen warned against buying CBD products online, because “there’s a lot of scams out there.” Yet his clinic sells CBD, and he admits, “I say ‘Don’t buy online,’ but ours is worth doing, because we know what we’re doing. We ship all over.”
THC and its major (inactive) metabolite, THC-COOH, can be measured in blood, urine, hair, oral fluid or sweat using chromatographic techniques as part of a drug use testing program or a forensic investigation of a traffic or other criminal offense.[52] The concentrations obtained from such analyses can often be helpful in distinguishing active use from passive exposure, elapsed time since use, and extent or duration of use. These tests cannot, however, distinguish authorized cannabis smoking for medical purposes from unauthorized recreational smoking.[141] Commercial cannabinoid immunoassays, often employed as the initial screening method when testing physiological specimens for marijuana presence, have different degrees of cross-reactivity with THC and its metabolites.[142] Urine contains predominantly THC-COOH, while hair, oral fluid and sweat contain primarily THC.[52] Blood may contain both substances, with the relative amounts dependent on the recency and extent of usage.[52]
In 1951, Congress passed the Boggs Act, which for the first time included Cannabis with narcotic drugs. In 1970, with the passage of the Controlled Substances Act, marijuana was classified by Congress as a Schedule I drug. Drugs in Schedule I are distinguished as having no currently accepted medicinal use in the United States. Other Schedule I substances include heroin, LSD, mescaline, and methaqualone.
An alternative to the gateway hypothesis is the common liability to addiction (CLA) theory. It states that some individuals are, for various reasons, willing to try multiple recreational substances. The "gateway" drugs are merely those that are (usually) available at an earlier age than the harder drugs. Researchers have noted in an extensive review that it is dangerous to present the sequence of events described in gateway "theory" in causative terms as this hinders both research and intervention.[259]
No medication seemed to provide a great deal of relief for Harper’s symptoms. But in 2013, three years after their trip to Boston, Penny and Dustin caught an installment of CNN’s medical marijuana documentary and began researching what they could obtain in Texas, where medical marijuana is illegal. Their internet searches soon led them to HempMedsPx and Real Scientific Hemp Oil. The company sent Penny a vial of hemp oil, which she administered to Harper that September.

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.

In 2012, voters in Colorado and Washington state passed initiatives legalizing cannabis for adults 21 and older under state law. In November 2014, Oregon, Alaska, and Washington D.C also approved recreational use of marijuana. In November 2016, four more states - California, Massachusetts, Maine, and Nevada - voted in recreational marijuana. It is important to note that the federal government still considers cannabis a dangerous drug and that the illegal distribution and sale of marijuana is a serious crime. Under the Controlled Substances Act (CSA), marijuana is still considered a Schedule 1 drug. Cultivation and distribution of marijuana are felonies; possession for personal use is a misdemeanor; possession of “paraphernalia” is also illegal. Cultivating 100 plants or more carries a mandatory minimum sentence of five years according to federal statutes.
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]
In Buddhism, cannabis is generally regarded as an intoxicant and may be a hindrance to development of meditation and clear awareness. In ancient Germanic culture, Cannabis was associated with the Norse love goddess, Freya.[120][121] An anointing oil mentioned in Exodus is, by some translators, said to contain Cannabis.[122] Sufis have used Cannabis in a spiritual context since the 13th century CE.[123]
Medical marijuana refers to the use of the Cannabis plant as a physician-recommended herbal therapy as well as synthetic[181] THC and cannabinoids. So far, the medical use of cannabis is legal only in a limited number of territories, including Canada,[37] Belgium, Australia, the Netherlands, Spain, and many U.S. states. This usage generally requires a prescription, and distribution is usually done within a framework defined by local laws. There is evidence supporting the use of cannabis or its derivatives in the treatment of chemotherapy-induced nausea and vomiting, neuropathic pain, and multiple sclerosis. Lower levels of evidence support its use for AIDS wasting syndrome, epilepsy, rheumatoid arthritis, and glaucoma.[74]

"Industrial hemp" means a fiber or oilseed crop, or both, that is limited to types of the plant Cannabis sativa L. having no more than three-tenths of 1 percent tetrahydrocannabinol (THC) contained in the dried flowering tops, whether growing or not; the seeds of the plant; the resin extracted from any part of the plant; and every compound, manufacture, salt, derivative, mixture, or preparation of the plant, its seeds or resin produced therefrom.
Since then, many different types of sex determination systems have been discovered, particularly in plants.[14] Dioecy is relatively uncommon in the plant kingdom, and a very low percentage of dioecious plant species have been determined to use the XY system. In most cases where the XY system is found it is believed to have evolved recently and independently.[30]
It is clear that there is a culture of idealistic believers in hemp in North America, and that there is great determination to establish the industry. As history has demonstrated, unbridled enthusiasm for largely untested new crops touted as gold mines sometimes leads to disaster. The attempt to raise silk in the US is probably the most egregious example. In 1826 a Congressional report that recommended the preparation of a practical manual on the industry resulted in a contagious desire to plant mulberries for silk production, with the eventual collapse of the industry, the loss of fortunes, and a legacy of “Mulberry Streets” in the US (Chapter 2, Bailey 1898). In the early 1980s in Minnesota, Jerusalem artichoke was touted as a fuel, a feed, a food, and a sugar crop. Unfortunately there was no market for the new “wonder crop” and hundreds of farmers lost about $20 million (Paarlberg 1990). The level of “hype” associated with industrial hemp is far more than has been observed before for other new crops (Pinfold Consulting 1998). Probably more so than any plant in living memory, hemp attracts people to attempt its cultivation without first acquiring a realistic appreciation of the possible pitfalls. American presidents George Washington and Thomas Jefferson encouraged the cultivation of hemp, but both lost money trying to grow it. Sadly in Canada in 1999 numerous farmers contracted to grow half of Canada’s crop area for hemp for the American-based Consolidated Growers and Processors, and with the collapse of the firm were left holding very large amounts of unmarketable grain and baled hemp straw. This has represented a most untimely setback for a fledgling industry, but at least has had a sobering effect on investing in hemp. In this section we emphasize why producers should exercise caution before getting into hemp.

When oral Cannabis is ingested, there is a low (6%–20%) and variable oral bioavailability.[1,2] Peak plasma concentrations of delta-9-tetrahydrocannabinol (THC) occur after 1 to 6 hours and remain elevated with a terminal half-life of 20 to 30 hours. Taken by mouth, delta-9-THC is initially metabolized in the liver to 11-OH-THC, a potent psychoactive metabolite. Inhaled cannabinoids are rapidly absorbed into the bloodstream with a peak concentration in 2 to 10 minutes, declining rapidly for a period of 30 minutes and with less generation of the psychoactive 11-OH metabolite.

Without arguing the merits of the above contentions, we point out that the legitimate use of hemp for non-intoxicant purposes has been inhibited by the continuing ferocious war against drug abuse. In this atmosphere, objective analysis has often been lacking. Unfortunately both proponents and opponents have tended to engage in exaggeration. Increasingly, however, the world is testing the potential of hemp in the field and marketplace, which surely must be the ultimate arbiters. De Guzman (2001), noting the pessimistic USDA report, observed that “Nevertheless, others point to the potential of [the] market. Hemp products have a growing niche market of their own, and the market will remain healthy and be well supported with many competing brands.”


Newer antiemetics (e.g., 5-HT3 receptor antagonists) have not been directly compared with Cannabis or cannabinoids in cancer patients. However, the Cannabis-extract oromucosal spray, nabiximols, formulated with 1:1 THC:CBD was shown in a small pilot randomized, placebo-controlled, double-blinded clinical trial in Spain to treat chemotherapy-related N/V.[39][Level of evidence: 1iC] ASCO antiemetic guidelines updated in 2017 states that evidence remains insufficient to recommend medical marijuana for either the prevention or treatment of N/V in patients with cancer who receive chemotherapy or radiation therapy.[30]
Under federal law, cannabis (from which both CBD and marijuana are derived) is illegal everywhere, although the laws against it aren’t generally enforced in states that have legalized marijuana. Some manufacturers claim that CBD culled from legally imported industrial hemp, which has little to no THC, is fine to ship across the U.S., but many experts disagree, noting that because hemp comes from the same species as marijuana, cannabis sativa, all CBD falls under the DEA’s Schedule 1 designation. “This creative interpretation of the law runs afoul of reality,” says the Brookings Institution, a Washington, DC, think tank.
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]
From the 1950s to the 1980s, the Soviet Union was the world's largest producer of hemp (3,000 km2 in 1970). The main production areas were in Ukraine,[82] 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.[83][84]
