Although marijuana smoke contains a number of carcinogens findings from a limited number of well-designed studies do not suggest an increased risk for the development of either lung or upper airway cancer from light or moderate use. However, the evidence is mixed when it comes to the carcinogenic risks of heavy, long-term marijuana users, according to this study.

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]
Although cannabis as a drug and industrial hemp both derive from the species Cannabis sativa and contain the psychoactive component tetrahydrocannabinol (THC), they are distinct strains with unique phytochemical compositions and uses.[6] Hemp has lower concentrations of THC and higher concentrations of cannabidiol (CBD), which decreases or eliminates its psychoactive effects.[6] The legality of industrial hemp varies widely between countries. Some governments regulate the concentration of THC and permit only hemp that is bred with an especially low THC content.[7][8]
In 1976, Canadian botanist Ernest Small[65] and American taxonomist Arthur Cronquist published a taxonomic revision that recognizes a single species of Cannabis with two subspecies: C. sativa L. subsp. sativa, and C. sativa L. subsp. indica (Lam.) Small & Cronq.[61] The authors hypothesized that the two subspecies diverged primarily as a result of human selection; C. sativa subsp. sativa was presumably selected for traits that enhance fiber or seed production, whereas C. sativa subsp. indica was primarily selected for drug production. Within these two subspecies, Small and Cronquist described C. sativa L. subsp. sativa var. spontanea Vav. as a wild or escaped variety of low-intoxicant Cannabis, and C. sativa subsp. indica var. kafiristanica (Vav.) Small & Cronq. as a wild or escaped variety of the high-intoxicant type. This classification was based on several factors including interfertility, chromosome uniformity, chemotype, and numerical analysis of phenotypic characters.[51][61][66]

To make matters more confusing, nine states (including California, Washington, and Colorado) let residents buy cannabis-based products with or without THC. Nearly two dozen other “medical marijuana states” allow the sale of cannabis, including capsules, tinctures, and other items containing CBD or THC, at licensed dispensaries to people whose doctors have certified that they have an approved condition (the list varies by state but includes chronic pain, PTSD, cancer, autism, Crohn’s disease, and multiple sclerosis). Sixteen more states legalized CBD for certain diseases. But because all these products are illegal according to the federal government, cannabis advocates are cautious. “By and large, the federal government is looking the other way,” says Paul Armentano, deputy director of the Washington, DC–based National Organization for the Reform of Marijuana Laws (NORML), but until federal laws are changed, “this administration or a future one could crack down on people who produce, manufacture, or use CBD, and the law would be on its side.”
Former House Speaker John Boehner (R-OH) is the latest public official to endorse significant marijuana law reforms after leaving office. “Over the last 10 or 15 years, the American people’s attitudes have changed dramatically,” he told Bloomberg. “I find myself in that same position.” Boehner, along with former Massachusetts Gov. Bill Weld (R), is joining … Continue reading Former GOP House Speaker Backs Marijuana Descheduling, Joins Cannabiz
The Cannabis plant has a history of medicinal use dating back thousands of years across many cultures.[110] The Yanghai Tombs, a vast ancient cemetery (54 000 m2) situated in the Turfan district of the Xinjiang Uyghur Autonomous Region in northwest China, have revealed the 2700-year-old grave of a shaman. He is thought to have belonged to the Jushi culture recorded in the area centuries later in the Hanshu, Chap 96B.[111] Near the head and foot of the shaman was a large leather basket and wooden bowl filled with 789g of cannabis, superbly preserved by climatic and burial conditions. An international team demonstrated that this material contained tetrahydrocannabinol, the psychoactive component of cannabis. The cannabis was presumably employed by this culture as a medicinal or psychoactive agent, or an aid to divination. This is the oldest documentation of cannabis as a pharmacologically active agent.[112]
One systematic review studied 30 randomized comparisons of delta-9-THC preparations with placebo or other antiemetics from which data on efficacy and harm were available.[31] Oral nabilone, oral dronabinol, and intramuscular levonantradol (a synthetic analog of dronabinol) were tested. Inhaled Cannabis trials were not included. Among all 1,366 patients included in the review, cannabinoids were found to be more effective than the conventional antiemetics prochlorperazine, metoclopramide, chlorpromazine, thiethylperazine, haloperidol, domperidone, and alizapride. Cannabinoids, however, were not more effective for patients receiving very low or very high emetogenic chemotherapy. Side effects included a feeling of being high, euphoria, sedation or drowsiness, dizziness, dysphoria or depression, hallucinations, paranoia, and hypotension.[31]
While cultivating marijuana’s non-intoxicating cousin is currently illegal in the U.S. outside of exceptions for state-approved hemp research programs authorized under the 2014 Farm Bill, there’s a strong possibility that industrial hemp will be broadly legalized—possibly by the end of the year—once the House and Senate reconcile their versions of a new Farm Bill and put it on the president’s desk.
With your seed or plant acquisition request, you must submit a copy of your industrial hemp growers license, the industrial hemp license for the firm providing the seed and third party test results showing the variety is below the .3%THC threshold. If you want to grow and sell clones, you must provide documentation of permission from the source that allows for replication of those genetics. All seed and clones being brought into the state or leaving the state must be shipped or brought DIRECTLY to the Tennessee Department of agriculture for inventory. Movement permits are required to track the purchase or movement of industrial hemp seed, seedling and clones (viable material).
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.
Plant, (kingdom Plantae), any multicellular eukaryotic life-form characterized by (1) photosynthetic nutrition (a characteristic possessed by all plants except some parasitic plants and underground orchids), in which chemical energy is produced from water, minerals, and carbon dioxide with the aid of pigments and the radiant energy of the Sun, (2)…

Hemp, the non-psychoactive variety of the cannabis sativa plant, is already being integrated into several mature markets such as food, textiles, construction, personal care and nutraceuticals. This relatively quiet cannabis relative is emerging as a potential commodity ripe to not only impact, but possibly revolutionize, tech-driven markets and economies around the world.


Cannabis for industrial uses is valuable in tens of thousands of commercial products, especially as fibre[106] ranging from paper, cordage, construction material and textiles in general, to clothing. Hemp is stronger and longer-lasting than cotton. It also is a useful source of foodstuffs (hemp milk, hemp seed, hemp oil) and biofuels. Hemp has been used by many civilizations, from China to Europe (and later North America) during the last 12,000 years.[106][107] In modern times novel applications and improvements have been explored with modest commercial success.[108][109]

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.


Plastic composites for automobiles are the second most important component of the hemp industry of the EU. Natural fibers in automobile composites are used primarily in press-molded parts (Fig. 18). There are two widespread technologies. In thermoplastic production, natural fibers are blended with polypropylene fibers and formed into a mat, which is pressed under heat into the desired form. In thermoset production the natural fibers are soaked with binders such as epoxy resin or polyurethane, placed in the desired form, and allowed to harden through polymerization. Hemp has also been used in other types of thermoplastic applications, including injection molding. The characteristics of hemp fibers have proven to be superior for production of molded composites. In European manufacturing of cars, natural fibers are used to reinforce door panels, passenger rear decks, trunk linings, and pillars. In 1999 over 20,000 t of natural fiber were used for these purposes in Europe, including about, 2,000 t of hemp. It has been estimated that 5–10 kg of natural fibers can be used in the molded portions of an average automobile (excluding upholstery). The demand for automobile applications of hemp is expected to increase considerably, depending on the development of new technologies (Karus et al. 2000).

My dad has severe advanced stage Dementia. Will CBD oil help him at this point? He is now refusing to eat any solid food, but will accept most drinks.In addition, he has lost a great deal of weight even though they're giving him Mega Shakes containing a full meals worth of proteins, etc. He gets at least 4 of these a day..some which he refuses. Is his Dementia too far gone for CBD oils to help him?
Based on reviews, smoking or vaporizing CBD vape oil seems to have less effects when compared to other methods of administering CBD, such as tinctures, capsules and sprays. On the flip side, others argue that smoking or vaporizing has less drawbacks than taking CBD orally, since ingesting CBD orally could result in inconsistent absorption and a delayed effect.
I have had several neurological conditions like Bells Palsy three times, double vision, paralysis of left side of tongue. I have a lot of relief whenever I have pain by taking an inflamattory drug etoshine90 mg. Presently I have started taking Steroids for my facial palsy. The various pains I was having on the left side of neck, below the left ear, dizziness, pain around the head have subsided immidiately after the first dose of prendisolone 60 mg.I have read that CBD hemp oil can be useful for my condition of neurological and inflammation issues. My question is what concentrate (mg) of the oil should I take and for how long. Any brand that you may suggest that are available in the UK. Thank you.

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.
In the United States, the legality of medical marijuana varies in substantial ways from state to state. There are currently 29 US states with legal medical cannabis laws, as well as the District of Columbia. That leaves 21 states where medical marijuana is entirely prohibited. Marijuana cultivation, possession, and use in any form is illegal at the federal level.
Cannabis impairs psychomotor performance in a wide variety of tasks, such as motor coordination, divided attention, and operative tasks of many types; human performance on complex machinery can be impaired for as long as 24 hours after smoking as little as 20 mg of THC in cannabis; there is an increased risk of motor vehicle accidents among persons who drive when intoxicated by cannabis.
Cannabis, also known as marijuana among other names,[n 1] is a psychoactive drug from the Cannabis plant used for medical or recreational purposes.[16][17][18] The main psychoactive part of cannabis is tetrahydrocannabinol (THC), one of 483 known compounds in the plant,[19] including at least 65 other cannabinoids.[20] Cannabis can be used by smoking, vaporizing, within food, or as an extract.[21]
I have/had ovarian/primary peritoneal cancer. I used thc/cbd oil pills I self made from the start. I am supposedly their “poster child”. I went thru with chemo and surgery. Oh that horror! But when I tried to tell two seperate doctors, the surgeon was all about it, and my oncologist threw a fit and said it was an anecdote. There are more than 100 studies at the NIH govt website.
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]

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
One claim is that Hearst believed[dubious – discuss] that his extensive timber holdings were threatened by the invention of the decorticator which he feared would allow hemp to become a cheap substitute for the paper pulp used for newspaper.[121][124] Historical research indicates this fear was unfounded because improvements of the decorticators in the 1930s – machines that separated the fibers from the hemp stem – could not make hemp fiber a cheaper substitute for fibers from other sources. Further, decorticators did not perform satisfactorily in commercial production.[125][121]
Side effects of CBD include sleepiness, decreased appetite, diarrhea, fatigue, malaise, weakness, sleeping problems, and others.[3] It does not have intoxicating effects like those caused by THC, and may have an opposing effect on disordered thinking and anxiety produced by THC.[7][10][11] CBD has been found to interact with a variety of different biological targets, including cannabinoid receptors and other neurotransmitter receptors.[7][12] The mechanism of action of CBD in terms of its psychoactive and therapeutic effects is not fully clear.[7]
In 2014, I founded New Frontier Data, an analytics and business intelligence reporting group dedicated to the global cannabis industry, after more than 20 years in finance, industry analytics, intelligence reporting and emerging markets. As such, I have had the privilege of following hemp’s emergence and evolution. Half a decade later, this robust, environmentally friendly, low -cost-to-produce plant has become one of the most diversely applied and globally significant natural resources in the world. Here is a look at its applications across several mature industries:
Cannabis can be prepared into various foods generally called ‘edibles’. It takes between 1-3 hours to feel the effects after eating cannabis.2 Impatient or naïve users may believe they have not taken enough to feel the effects, and if they consume more they may find later that the psychoactive effects are unpleasantly strong. When edible products have inconsistent levels of THC even experienced users may find it difficult to regulate the amount consumed.
Hempseed's amino acid profile is comparable to other sources of protein such as meat, milk, eggs and soy.[20] Protein digestibility-corrected amino acid scores (PDCAAS), which attempt to measure the degree to which a food for humans is a "complete protein", were 0.49–0.53 for whole hemp seed, 0.46–0.51 for hempseed meal, and 0.63–0.66 for hulled hempseed.[21]
