Animal studies have suggested a synergistic analgesic effect when cannabinoids are combined with opioids. The results from one pharmacokinetic interaction study have been reported. In this study, 21 patients with chronic pain were administered vaporized Cannabis along with sustained-release morphine or oxycodone for 5 days.[57] The patients who received vaporized Cannabis and sustained-release morphine had a statistically significant decrease in their mean pain score over the 5-day period; those who received vaporized Cannabis and oxycodone did not. These findings should be verified by further studies before recommendations favoring such an approach are warranted in general clinical practice.
Hemp crops are tall, have thick foliage, and can be planted densely, and thus can be grown as a smother crop to kill tough weeds.[45] Using hemp this way can help farmers avoid the use of herbicides, gain organic certification, and gain the benefits of crop rotation. However, due to the plant's rapid and dense growth characteristics, some jurisdictions consider hemp a prohibited and noxious weed, much like Scotch Broom.[citation needed]
Cannabinoids are a class of compounds that interact with receptors throughout your body. CBD is just one of dozens of cannabinoids found in cannabis, including tetrahydrocannabinol (THC), which is the one responsible for marijuana’s famous high. Medical cannabis is technically any cannabis product used for medicinal purposes, and these can contain THC or CBD or both, said Nick Jikomes, a neuroscientist at Leafly, a website that provides information about legal cannabis. “A common mistake people make is to think that CBD is ‘the medical cannabinoid’ and THC is ‘the recreational cannabinoid.’” That’s inaccurate, he said, because THC is a potent anti-inflammatory and can be helpful for pain.
Dr. Ethan Russo, medical director at Phytecs, a biotechnology company spearheading research into plant- based medicines and the endocannabinoid system, took issue with Titus’s claim, however. “Bioaccumulators can recruit heavy metals from the soil,” Russo said, “but breaking them down would be alchemy.” Government regulation of the pharmaceutical industry is designed to protect consumers from unfounded scientific claims.

Many monoecious varieties have also been described,[19] in which individual plants bear both male and female flowers.[20] (Although monoecious plants are often referred to as "hermaphrodites", true hermaphrodites – which are less common in Cannabis – bear staminate and pistillate structures together on individual flowers, whereas monoecious plants bear male and female flowers at different locations on the same plant.) Subdioecy (the occurrence of monoecious individuals and dioecious individuals within the same population) is widespread.[21][22][23] Many populations have been described as sexually labile.[24][25][26]

The Drug Enforcement Agency and the Office of National Drug Control Policy of the US raised concerns over tests conducted from 1995 to 1997 that showed that consumption of hempseed products available during that period led to interference with drug-testing programs for marijuana use. Federal US programs utilize a THC metabolite level of 50 parts per billion in urine. Leson (2000) found that this level was not exceeded by consuming hemp products, provided that THC levels are maintained below 5 ppm in hemp oil, and below 2 ppm in hulled seeds. Nevertheless the presence of even minute trace amounts of THC in foods remains a tool that can be used by those wishing to prevent the hemp oilseed industry from developing.
There are hundreds of compounds in marijuana, but scientists believe the one responsible for the drugs' psychoactive effects is tetrahydrocannbinol, or THC. THC binds to cannabinoid receptors throughout the body, and marijuana's "high" comes from THC's binding to brain regions responsible for pleasure, time perception and pain, according to the National Institute on Drug Abuse (NIDA). 
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]
Fig. 8. Scanning electron micrographs of the abaxial surface of a perigonal bract (which envelops the fruit). These bracts are the most intoxicating part of the plant, and may contain 20% THC, dry weight. The resin is synthesized both in stalked and sessile glands. Multicellular secretory glands (of phallic appearance), some broken stalks of these (note cellular appearance), and unicellular cystolith hairs (claw-like structures) are pictured. Fig. 9. Some important cannabinoids of cannabis resin. D9-THC (delta-9 tetrahydrocannabinol) is the chief intoxicant chemical and predominates in intoxicant strains, while the isomer D8-THC is usually present in no more than trace amounts. CBD (cannabidiol) is the chief non-intoxicant chemical, and predominates in non-intoxicant strains; it has sedative effects. The non-intoxicant CBN (cannabinol) is a frequent degradation or oxidation product. The non-intoxicant cannabichromene (CBC) is typically found in trace amounts in intoxicant strains. The non-intoxicant cannabigerol (CBG) is considered to be a precursor of the other cannbinoids (see Fig. 10).
Cannabis is predominantly dioecious,[12][14] having imperfect flowers, with staminate "male" and pistillate "female" flowers occurring on separate plants.[15] "At a very early period the Chinese recognized the Cannabis plant as dioecious",[16] and the (c. 3rd century BCE) Erya dictionary defined xi 枲 "male Cannabis" and fu 莩 (or ju 苴) "female Cannabis".[17] Male flowers are normally borne on loose panicles, and female flowers are borne on racemes.[18]
Although hemp can be successfully grown continuously for several years on the same land, rotation with other crops is desirable. A 3- or preferably 4-year rotation may involve cereals, clover or alfalfa for green manure, maize, and hemp. In Ontario it has been recommended that hemp not follow canola, edible beans, soybeans or sunflowers. However, according to Bócsa and Karus (1998), “it matters little what crops are grown prior to hemp.”

There are ways to strain dangerous contaminants out of raw hemp paste. And most companies stand behind their quality and safety procedures. “We continuously test all our products ... to ensure our consumers get the levels of natural constituents they expect from the quality hemp stalk oil they purchase,” HempMedsPx states on its web site. “Additionally, all our products are tested for safety, to ensure there are no solvents, heavy metals, or other potentially harmful materials in our oil. Because we take these steps, we are always confident in our products, and you can be too.”


In the 1970s, the taxonomic classification of Cannabis took on added significance in North America. Laws prohibiting Cannabis in the United States and Canada specifically named products of C. sativa as prohibited materials. Enterprising attorneys for the defense in a few drug busts argued that the seized Cannabis material may not have been C. sativa, and was therefore not prohibited by law. Attorneys on both sides recruited botanists to provide expert testimony. Among those testifying for the prosecution was Dr. Ernest Small, while Dr. Richard E. Schultes and others testified for the defense. The botanists engaged in heated debate (outside of court), and both camps impugned the other's integrity.[56][57] The defense attorneys were not often successful in winning their case, because the intent of the law was clear.[64]

Medical reviews published in 2017 and 2018 incorporating numerous clinical trials concluded that cannabidiol is an effective treatment for certain types of childhood epilepsy.[19][20] An orally administered cannabidiol solution (brand name Epidiolex) was approved by the US Food and Drug Administration in June 2018 as a treatment for two rare forms of childhood epilepsy, Lennox-Gastaut syndrome and Dravet syndrome.[13]

Acute effects may include anxiety and panic, impaired attention, and memory (while intoxicated), an increased risk of psychotic symptoms, and possibly an increased risk of accidents if a person drives a motor vehicle while intoxicated.[68] Short-term cannabis intoxication can hinder the mental processes of organizing and collecting thoughts. This condition is known as temporal disintegration.[69] Psychotic episodes are well-documented and typically resolve within minutes or hours. There have been few reports of symptoms lasting longer.[70][71]
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]
Throughout his lifetime, George Washington cultivated hemp at Mount Vernon for industrial uses. The fibers from hemp held excellent properties for making rope and sail canvas. In addition, hemp fibers could be spun into thread for clothing or, as indicated in Mount Vernon records, used in repairing the large seine nets Washington used in his fishing operation along the Potomac.
Hemp oil has never been as popular as other marijuana products. With little to no THC, CBD-rich strains of cannabis don’t deliver the pleasant buzz recreational users seek out in marijuana. In the 1970s, however, scientists found that cannabidiol was effective in reducing seizures. The brain’s endocannabinoid system contains receptors that respond to CBD, producing anticonvulsant effects. Being plant-derived and native to the brain’s own chemistry, CBD is therefore one of the most natural options for seizure treatment available today. Still, not many people took interest in CBD until 2013, when a CNN documentary special, Weed, hosted by the network’s chief medical correspondent, Dr. Sanjay Gupta, highlighted CBD’s effectiveness in combating seizures. Since then, demand for hemp oil products has exploded.
Cannabis (also called pot, marijuana, weed, dope, grass, mull, dak, hash, smoke, buds, skunk, cabbage, ganja, reefer) is the most commonly used illegal drug in New Zealand. Cannabis comes from the Cannabis Sativa plant and is used both for recreational and medicinal purposes. As a recreational drug, it can be used in a dried plant, resin, or oil form. The potency of cannabis depends on it's concentration of THC, which is higher in resin and oil than in the dried plant. The psychoactive potency of cannabis depends on its concentration of THC, which is higher in resin and hash oil. Cannabis is widely available in New Zealand.

The Department has policies and procedures in place for the commonwealth's hemp research program, which can be found in the 2019 Pilot Program Parameters. Researchers from institutions of higher education or growers who would like to be considered for participation in the 2019 program must submit a 2019 PDA Industrial Hemp Research Pilot Program Permit Application prior to the application deadline of December 17, 2018. Researchers who participated in the 2018 Pilot Program may submit a Permit Renewal form by December 17, 2018 to continue their projects in the 2019 growing season. 


Selection for fiber has resulted in strains that have much more bark fiber tissues and much less woody core than encountered in narcotic strains, oilseed strains, and wild plants (Fig. 12). In non-fiber strains of Cannabis, bark can be less than one quarter of the stem tissues (i.e. more than three quarters can be woody core). By contrast, in fiber strains half of the stem tissues can be bark, and more than half of this can be the desirable long primary fibers (de Meijer 1995). Non-fiber strains rarely have as much as 15% fiber in the bark.

Hi, I had ovarian cancer stage 2 and went to do chemotherapy for 16 times in 2014. It came back last year 2016 but I did not do chemotherapy or radiation therapy as suggested by the doctor. I am taking hormone therapy at the moment. I would like to use cannabis oil but which one and how much CBD and how much THC should I take for ovarian cancer? Can anyone give some idea?. Thank you very much.

Short-term use of the drug impairs thinking and coordination. In long-term studies, teens who smoke marijuana have lower IQs later on, as well as structural differences in their brains, though scientists debate whether this is an effect of the drug or a result of habitual pot smokers seeking out less intellectually stimulating pursuits. A 2016 study on almost 300 students by the University of Montreal published in the journal Development and Psychopathology found that teens who start smoking around age 14 do worse on some cognitive tests by age 20 than non-smokers. They also have a higher school dropout rate. If they wait until age 17 to start, though, the smokers do not seem to have the same impairments, according to the study. 

Donald Abrams was a member of the committee that reviewed the evidence that went into producing the report, and he said that the studies they reviewed overwhelmingly used pharmaceutically available preparations that contain THC, including dronabinol, nabilone and the whole-plant extract spray nabiximols, which contains equal parts CBD and THC. It’s impossible to know whether the benefits of cannabis can also be obtained from CBD alone, Abrams said, because CBD is just one of 400 chemicals present in the plant. So far, CBD in isolation has been studied in only a handful of randomized, placebo-controlled trials (considered the gold standard of evidence in medical research), and the evidence remains sparse.

Hernandez said interactions between FDA-approved pharmaceuticals and CBD oils are a serious concern. “What we’ve found so far is that [CBD] can actually affect the levels of some of your epilepsy medications,” Hernandez told me. The diarrhea and vomiting associated with CBD oil ingestion can lower the levels of other drugs in patients’ bloodstreams, while the way the body absorbs CBD can raise the levels of certain medications.
A short-term Advisory Board has been appointed to serve through the development of the rules and regulations. The rules and regulations themselves will identify the guidelines for formation of the Advisory Board, so upon adoption of the rules and regulations an Advisory Board will be created which will continue on a regular basis beyond that point. 
Hemp production has been legalized in North Carolina, but only as part of the state's pilot program as allowed under federal law. As such, it will still be awhile before the first fields are planted. The N.C. General Assembly passed Senate Bill 313 in 2015, allowing the Industrial Hemp Commission to develop the rules and licensing structure necessary to stay within federal laws. The law was modified in 2016 in House Bill 992. The Industrial Hemp Commission adopted temporary rules for review in February 2017. The Rules Review Commission of the Office of Administrative Hearings voted to approve these rules Feb. 16.
Most pro-hemp initiatives in the United States are now focused on defining and distinguishing between industrial hemp and marijuana. Some pro-hemp supporters would like to move the control of U.S. hemp production from the DEA to the USDA. Proponents of legalizing hemp also argue that new technology to distinguish THC levels both in the field and from the air will allow for adequate production enforcement.
You cannot have a fatal overdose from cannabis use. However, if you have too much in one session it can lead to a very unpleasant experience. Anxiety and panic attacks, disorientation, and inability to focus are all signs you have had too much. Other negative effects from taking too much include loss of coordination, shortness of breath, increased heart rate and shaking, chills and sweats. 
Protein. Hemp seeds contain 25%–30% protein, with a reasonably complete amino acid spectrum. About two thirds of hempseed protein is edestin. All eight amino acids essential in the human diet are present, as well as others. Although the protein content is smaller than that of soybean, it is much higher than in grains like wheat, rye, maize, oat, and barley. As noted above, the oilcake remaining after oil is expressed from the seeds is a very nutritious feed supplement for livestock, but it can also be used for production of a high-protein flour.
"A CBD company may create a CBD oil, test it, and use the test results to create their label," Bonn-Miller says. "The problem is if they never test their product again, or they test it once a year, you have no idea whether each batch is the same as the first one that they used to create the label. The vast majority of companies are not using manufacturing standards that assure product consistency over time. Companies should be testing every batch they make and tossing batches that don't fall within the specs of their label."
Unlike other Cannabis sativa varieties and hybrids, which are mostly grown for their chemically potent flowers (or 'buds'), hemp is also legally distinguished from marijuana in the US as containing less than 0.3% of the cannabinoid chemical THC — considered to be the most intoxicating, psychoactive component in cannabis plants, as well as a treatment option for certain serious illnesses.

Retting is generally done in the field (Fig. 46, 47). This typically requires weeks. The windrows should be turned once or twice. If not turned, the stems close to the ground will remain green while the top ones are retted and turn brown. When the stalks have become sufficiently retted requires experience—the fibers should have turned golden or grayish in color, and should separate easily from the interior wood. Baling can be done with any kind of baler (Fig. 48). Stalks should have less than 15% moisture when baled, and should be allowed to dry to about 10% in storage. Bales must be stored indoors. Retted stalks are loosely held together, and for highest quality fiber applications need to be decorticated, scutched, hackled, and combed to remove the remaining pieces of stalks, broken fibers, and extraneous material. The equipment for this is rare in North America, and consequently use of domestically-produced fiber for high quality textile applications is extremely limited. However, as described above relatively crude fiber preparations also have applications.
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.

There’s also been a lot of talk lately about “microdosing” CBD. This refers to an incremental process of finding your minimum effective dose. You can do this with any concentration of CBD oil, but lower concentrations will take longer. In a 2017 article in Rolling Stone, Dr. Dustan Sulak outlines his protocol for microdosing. You can begin this process by asking yourself three questions:
In a follow-up, single-dose study involving 36 patients, it was reported that 10 mg doses of delta-9-THC produced analgesic effects during a 7-hour observation period that were comparable to 60 mg doses of codeine, and 20 mg doses of delta-9-THC induced effects equivalent to 120 mg doses of codeine.[51] Higher doses of THC were found to be more sedative than codeine.
According to Delphic analysis by British researchers in 2007, cannabis has a lower risk factor for dependence compared to both nicotine and alcohol.[97] However, everyday use of cannabis may be correlated with psychological withdrawal symptoms, such as irritability or insomnia,[93] and susceptibility to a panic attack may increase as levels of THC metabolites rise.[98][99] However, cannabis withdrawal symptoms are typically mild and are never life-threatening.[100]

There are many ways to prepare cannabis for consumption. And while final marijuana products may come in many forms, each aims to provide rich concentrations of the terpenes, cannabinoids, and other desirable compounds the marijuana plant produces. From the simple process of drying and curing marijuana flowers, to the sophisticated chemistry of producing cannabis concentrates, here’s a guide to the most common forms of cannabis.
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]

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.
The CBD utilized in our tinctures is extracted from industrial hemp cultivated in the United States. To further ensure quality and purity, our industrial hemp goes through a supercritical CO2 extraction process to obtain the best possible CBD solution. This solution is then formulated by our board-certified pharmacists into finished products and sent out for third-party testing. Our CBD oil is made with high-quality CBD extracted from organic hemp that is abundant in naturally produced terpenes, oils, vitamins, omega fatty acids, and other components.
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.
Each and every bottle is grown and processed with the same standards as the last guaranteeing quality and assuring potency. Made from CBD rich hemp flower sun grown in Oregon and MCT oil, Rosebud is proud to be a Vegan, Gluten Free, Non-GMO, Organic, and Sustainably Processed CO2 extract. Choose between our three potencies: 350mg, 700mg and 1000mg. 
The dosages mentioned do not take into account the strength of the tincture. I have Elixinol 300, I took 1/2 dropper (0.5ml, which offers 5mg of CBD) as indicated on the bottle and felt severely nauseous for 3 hours thereafter. There is no way I cold take this dose twice per day, as recommended on the bottle. The high dosages on this site must surely be for much weaker concentrations?
Germplasm for the improvement of hemp is vital for the future of the industry in North America. However, there are no publicly available germplasm banks housing C. sativa in North America. The hundreds of seed collections acquired for Small’s studies (reviewed in Small 1979) were destroyed in 1980 because Canadian government policy at that time envisioned no possibility that hemp would ever be developed as a legitimate crop. An inquiry regarding the 56 United States Department of Agriculture hemp germplasm collections supplied to and grown by Small and Beckstead (1973) resulted in the reply that there are no remaining hemp collections in USDA germplasm holdings, and indeed that were such to be found they would have to be destroyed. While hemp has been and still is cultivated in Asia and South America, it is basically in Europe that germplasm banks have made efforts to preserve hemp seeds. The Vavilov Institute of Plant Research in St. Petersburg, Russia has by far the largest germplasm collection of hemp of any public gene bank, with about 500 collections. Detailed information on the majority of hemp accessions of the Vavilov Institute can be found in Anon. (1975). Budgetary problems in Russia have endangered the survival of this invaluable collection, and every effort needs to be made to find new funding to preserve it. Maintenance and seed generation issues for the Vavilov hemp germplasm collection are discussed in a number of articles in the Journal of the International Hemp Association (Clarke 1998b; Lemeshev et al. 1993, 1994). The Gatersleben gene bank of Germany, the 2nd largest public gene bank in Europe, has a much smaller Cannabis collection, with less than 40 accessions (detailed information on the hemp accessions of the Gatersleben gene bank are available at fox-serv.ipk-gatersleben.de/). Because hemp is regaining its ancient status as an important crop, a number of private germplasm collections have been assembled for the breeding of cultivars as commercial ventures (de Meijer and van Soest 1992; de Meijer 1998), and of course these are available only on a restricted basis, if at all.

A 2015 meta analysis found that, although a longer period of abstinence was associated with smaller magnitudes of impairment, both retrospective and prospective memory were impaired in cannabis users. The authors concluded that some, but not all, of the deficits associated with cannabis use were reversible.[114] A 2012 meta analyses found that deficits in most domains of cognition persisted beyond the acute period of intoxication, but was not evident in studies where subjects were abstinent for more than 25 days.[115] Few high quality studies have been performed on the long-term effects of cannabis on cognition, and results were generally inconsistent.[116] Furthermore, effect sizes of significant findings were generally small.[115] One review concluded that, although most cognitive faculties were unimpaired by cannabis use, residual deficits occurred in executive functions.[117] Impairments in executive functioning are most consistently found in older populations, which may reflect heavier cannabis exposure, or developmental effects associated with adolescent cannabis use.[118] One review found three prospective cohort studies that examined the relationship between self reported cannabis use and intelligence quotient (IQ). The study following the largest number of heavy cannabis users reported that IQ declined between ages 7–13 and age 38. Poorer school performance and increased incidence of leaving school early were both associated with cannabis use, although a causal relationship was not established.[110] Cannabis users demonstrated increased activity in task-related brain regions, consistent with reduced processing efficiency.[119]


Cannabis is indigenous to Central Asia and Indian subcontinent,[183] and its use for fabric and rope dates back to the Neolithic age in China and Japan.[184][185] It is unclear when cannabis first became known for its psychoactive properties; some scholars suggest that the ancient Indian drug soma, mentioned in the Vedas, was cannabis, although this theory is disputed.[186]
Jump up ^ Blest-Hopley G, Giampietro V, Bhattacharyya S (May 2018). "Residual effects of cannabis use in adolescent and adult brains - A meta-analysis of fMRI studies". Neuroscience and Biobehavioral Reviews. 88: 26–41. doi:10.1016/j.neubiorev.2018.03.008. PMID 29535069. 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.
Epidemiologic studies examining one association of Cannabis use with head and neck squamous cell carcinomas have also been inconsistent in their findings. A pooled analysis of nine case-control studies from the U.S./Latin American International Head and Neck Cancer Epidemiology (INHANCE) Consortium included information from 1,921 oropharyngeal cases, 356 tongue cases, and 7,639 controls. Compared with those who never smoked Cannabis, Cannabis smokers had an elevated risk of oropharyngeal cancers and a reduced risk of tongue cancer. These study results both reflect the inconsistent effects of cannabinoids on cancer incidence noted in previous studies and suggest that more work needs to be done to understand the potential role of human papillomavirus infection.[10] A systematic review and meta-analysis of nine case-control studies involving 13,931 participants also concluded that there was insufficient evidence to support or refute a positive or negative association between Cannabis smoking and the incidence of head and neck cancers.[11]
Cannabis use for medicinal purposes dates back at least 3,000 years.[1-5] It was introduced into Western medicine in 1839 by W.B. O’Shaughnessy, a surgeon who learned of its medicinal properties while working in India for the British East India Company. Its use was promoted for reported analgesic, sedative, anti-inflammatory, antispasmodic, and anticonvulsant effects.
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): www.gov.on.ca/OMAFRA/english/crops/hort/hemp.html); for Manitoba (several documents): www.gov.mb.ca/agriculture/crops/hemp/bko01s00.html; for British Columbia: (BC Ministry of Agriculture and Foods Fact Sheet on Industrial Hemp, prepared by A. Oliver and H. Joynt): www.agf.gov.bc.ca/croplive/plant/horticult/specialty/specialty.htm
Cannabis is believed to be an aggravating factor in rare cases of arteritis, a serious condition that in some cases leads to amputation. Because 97% of case-reports also smoked tobacco, a formal association with cannabis could not be made. If cannabis arteritis turns out to be a distinct clinical entity, it might be the consequence of vasoconstrictor activity observed from delta-8-THC and delta-9-THC.[100] Other serious cardiovascular events including myocardial infarction, stroke,[101] sudden cardiac death, and cardiomyopathy have been reported to be temporally associated with cannabis use. Research in these events is complicated because cannabis is often used in conjunction with tobacco, and drugs such as alcohol and cocaine.[102] These putative effects can be taken in context of a wide range of cardiovascular phenomena regulated by the endocannabinoid system and an overall role of cannabis in causing decreased peripheral resistance and increased cardiac output, which potentially could pose a threat to those with cardiovascular disease.[103] There is some evidence from case reports that cannabis use may provoke fatal cardiovascular events in young people who have not been diagnosed with cardiovascular disease.[78] Smoking cannabis has also been shown to increase the risk of myocardial infarction by 4.8 times for the 60 minutes after consumption.[104]
Heavy, long term exposure to marijuana may have biologically-based physical, mental, behavioral and social health consequences and may be "associated with diseases of the liver (particularly with co-existing hepatitis C), lungs, heart, and vasculature".[79] It is recommended that cannabis use be stopped before and during pregnancy as it can result in negative outcomes for both the mother and baby.[80][81] However, maternal use of marijuana during pregnancy does not appear to be associated with low birth weight or early delivery after controlling for tobacco use and other confounding factors.[82] A 2014 review found that while cannabis use may be less harmful than alcohol use, the recommendation to substitute it for problematic drinking is premature without further study.[83] Other side effects include cannabinoid hyperemesis syndrome.[84]

It was the seizures that tipped Penny off that something wasn’t right with Harper after she and her husband Dustin brought her home from the hospital as a newborn. Several months later, having tried a battery of epilepsy medications and still without a diagnosis, Penny and Dustin flew to Boston with Harper to see an expert in infant seizures. It was there they first heard of CDKL5. “This is the point where life changed significantly,” Penny said, “because now we had this diagnosis. You know, this abnormality in our family that we cannot fix.”


In 2015, almost half of the people in the United States had tried marijuana, 12% had used it in the past year, and 7.3% had used it in the past month.[31] In 2014, daily marijuana use amongst US college students had reached its highest level since records began in 1980, rising from 3.5% in 2007 to 5.9% in 2014 and had surpassed daily cigarette use.[239]
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.
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]
Hi Marilyn, I would recommend a topical lotion or salve to start for instant relief.. Maybe 250 to 300 mg tincture to see how you feel. For me, the salve took the pain in my hands away in under a minute. I didn't notice how much the tincture worked until I forgot to take on vacation. Pain that was pretty much gone but came back, I was tired, grumpy and felt horrible. It works, just need to find right product and dosage for you.

Indeed, hemp oil products have grown out of a market largely devoid of regulations or safety protocols. The state of the CBD industry harks back to the age of elixirs and potions hawked from covered wagons to the awed denizens of pioneer towns. There are no industrywide standards in place to ensure that CBD oils are consistently formulated batch-to-batch. There is no regulatory body screening products for pesticides, heavy metals, solvent residues, and other dangerous contaminants. The laboratories that companies contract to test their CBD products are themselves neither standardized nor consistently regulated. No medical research exists to recommend how much CBD a patient should take, nor is there detailed, reliable documentation of how CBD interacts with most epilepsy medications.
Fatty Acids. The quality of an oil or fat is most importantly determined by its fatty acid composition. Hemp is of high nutritional quality because it contains high amounts of unsaturated fatty acids, mostly oleic acid (C18:1, 10%–16%), linoleic acid (C18:2, 50%–60%), alpha-linolenic acid (C18:3, 20%–25%), and gamma-linolenic acid (C18:3, 2%–5%) (Fig. 37). Linoleic acid and alpha-linolenic acid are the only two fatty acids that must be ingested and are considered essential to human health (Callaway 1998). In contrast to shorter-chain and more saturated fatty acids, these essential fatty acids do not serve as energy sources, but as raw materials for cell structure and as precursors for biosynthesis for many of the body’s regulatory biochemicals. The essential fatty acids are available in other oils, particularly fish and flaxseed, but these tend to have unpleasant flavors compared to the mellow, slightly nutty flavor of hempseed oil. While the value of unsaturated fats is generally appreciated, it is much less well known that the North American diet is serious nutritionally unbalanced by an excess of linoleic over alpha-linonenic acid. In hempseed, linoleic and alpha-linolenic occur in a ratio of about 3:1, considered optimal in healthy human adipose tissue, and apparently unique among common plant oils (Deferne and Pate 1996). Gamma-linolenic acid or GLA is another significant component of hemp oil (1%–6%, depending on cultivar). GLA is a widely consumed supplement known to affect vital metabolic roles in humans, ranging from control of inflammation and vascular tone to initiation of contractions during childbirth. GLA has been found to alleviate psoriasis, atopic eczema, and mastalgia, and may also benefit cardiovascular, psychiatric, and immunological disorders. Ageing and pathology (diabetes, hypertension, etc.) may impair GLA metabolism, making supplementation desirable. As much as 15% of the human population may benefit from addition of GLA to their diet. At present, GLA is available in health food shops and pharmacies primarily as soft gelatin capsules of borage or evening primrose oil, but hemp is almost certainly a much more economic source. Although the content of GLA in the seeds is lower, hemp is far easier to cultivate and higher-yielding. It is important to note that hemp is the only current natural food source of GLA, i.e. not requiring the consumption of extracted dietary supplements. There are other fatty acids in small concentrations in hemp seed that have some dietary significance, including stearidonic acid (Callaway et al. 1996) and eicosenoic acid (Mölleken and Theimer 1997). Because of the extremely desirable fatty acid constitution of hemp oil, it is now being marketed as a dietary supplement in capsule form (Fig. 38).

Jews living in Palestine in the 2nd century were familiar with the cultivation of hemp, as witnessed by a reference to it in the Mishna (Kil'ayim 2:5) as a variety of plant, along with Arum, that sometimes takes as many as three years to grow from a seedling. In late medieval Germany and Italy, hemp was employed in cooked dishes, as filling in pies and tortes, or boiled in a soup.[109] Hemp in later Europe was mainly cultivated for its fibers, and was used for ropes on many ships, including those of Christopher Columbus. The use of hemp as a cloth was centered largely in the countryside, with higher quality textiles being available in the towns.
