An in vitro study of the effect of CBD on programmed cell death in breast cancer cell lines found that CBD induced programmed cell death, independent of the CB1, CB2, or vanilloid receptors. CBD inhibited the survival of both estrogen receptor–positive and estrogen receptor–negative breast cancer cell lines, inducing apoptosis in a concentration-dependent manner while having little effect on nontumorigenic mammary cells. Other studies have also shown the antitumor effect of cannabinoids (i.e., CBD and THC) in preclinical models of breast cancer.[19,20]

A randomized, placebo-controlled, crossover pilot study of nabiximols in 16 patients with chemotherapy-induced neuropathic pain showed no significant difference between the treatment and placebo groups. A responder analysis, however, demonstrated that five patients reported a reduction in their pain of at least 2 points on an 11-point scale, suggesting that a larger follow-up study may be warranted.
But there’s a big difference between the two. Hemp seed oil has been pressed from hemp seed, and it’s great for a lot of things – it’s good for you, tastes great, and can be used in soap, paint – even as biodiesel fuel. However, hemp seed oil does not contain any concentration of cannabinoids at all, including CBD. So by all means, stock up at your local natural food store. Just don’t expect to reap the benefits of a true CBD oil when you cook with hemp seed oil.

The first example of the use of hempcrete was in 1986 in France with the renovation of the Maison de la Turquie in Nogent-sur-Seine by the innovator Charles Rasetti. In the UK hemp lime was first used in 2000 for the construction of two test dwellings in Haverhill. Designed by Modece Architects, who pioneered hemp's use in UK construction, the hemp houses were monitored in comparison with other standard dwellings by BRE. Completed in 2009, the Renewable House is one of the most technologically advanced made from hemp-based materials. The first US home made of hemp-based materials was completed in August 2010 in Asheville, North Carolina.
Hemp, Canabis sativa is a plant originally from central Asia. It was cultivated with, and sometimes in place of flax because the stem fibers are similar. By the seventeenth century, Russia, Latvia, and other countries around the Baltic Sea were the major producers of hemp. It was from these areas Britain obtained its supply. However, during periods of military hostilities, the English had trouble acquiring enough hemp.

In a randomized clinical trial, researchers compared the safety and effectiveness of orally administered Cannabis extract (2.5 mg THC and 1 mg CBD), THC (2.5 mg), or placebo for the treatment of cancer-related anorexia-cachexia in 243 patients with advanced cancer who received treatment twice daily for 6 weeks. Results demonstrated that although these agents were well tolerated by these patients, no differences were observed in patient appetite or quality of life among the three groups at this dose level and duration of intervention.
As noted above, hemp seed cake makes an excellent feed for animals. However, feeding entire plants is another matter, because the leaves are covered with the resin-producing glands. While deer, groundhogs, rabbits, and other mammals will nibble on hemp plants, mammals generally do not choose to eat hemp. Jain and Arora (1988) fed narcotic Cannabis refuse to cattle, and found that the animals “suffered variable degrees of depression and revealed incoordination in movement.” By contrast, Letniak et al. (2000) conducted an experimental trial of hemp as silage. No significant differences were found between yield of the hemp and of barley/oat silage fed to heifers, suggesting that fermenting hemp plants reduces possible harmful constituents.
Prior to 2005's Hurricane Katrina, which caused widespread destruction and fatalities across New Orleans, Johnson had moved to California, and spent years there soaking up knowledge and culture around cannabis plants and the industry. After witnessing the pain and nausea his mother experienced during her treatment, Johnson decided to help bring the medicinal and economic value of cannabis back to his hometown, starting with hemp.
Several of the cannabinoids are reputed to have medicinal potential: THC for glaucoma, spasticity from spinal injury or multiple sclerosis, pain, inflammation, insomnia, and asthma; CBD for some psychological problems. The Netherlands firm HortaPharm developed strains of Cannabis rich in particular cannabinoids. The British firm G.W. Pharmaceuticals acquired proprietary access to these for medicinal purposes, and is developing medicinal marijuana. In the US, NIH (National Institute of Health) has a program of research into medicinal marijuana, and has supplied a handful of individuals for years with maintenance samples for medical usage. The American Drug Enforcement Administration is hostile to the medicinal use of Cannabis, and for decades research on medicinal properties of Cannabis in the US has been in an extremely inhospitable climate, except for projects and researchers concerned with curbing drug abuse. Synthetic preparations of THC—dronabinol (Marinol®) and nabilone (Cesamet®)—are permitted in some cases, but are expensive and widely considered to be less effective than simply smoking preparations of marijuana. Relatively little material needs to be cultivated for medicinal purposes (Small 1971), although security considerations considerably inflate costs. The potential as a “new crop” for medicinal cannabinoid uses is therefore limited. However, the added-value potential in the form of proprietary drug derivatives and drug-delivery systems is huge. The medicinal efficacy of Cannabis is extremely controversial, and regrettably is often confounded with the issue of balancing harm and liberty concerning the proscriptions against recreational use of marijuana. This paper is principally concerned with the industrial uses of Cannabis. In this context, the chief significance of medicinal Cannabis is that, like the issue of recreational use, it has made it very difficult to rationally consider the development of industrial hemp in North America for purposes that everyone should agree are not harmful.

“Hemp is of high nutritional quality because it contains high amounts of unsaturated fatty acids… Linoleic acid and alpha-linolenic acid are the only two fatty acids that must be ingested and are considered essential to human health … 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…”
Liquid CBD Oil/Tinctures/Extracts: Drops or tinctures should have a “suggested serving size” and the total milligrams of CBD listed on their packaging. From there, you can determine the amount of CBD you would like to ingest. Simply place the correct quantity of drops under your tongue using the dropper and hold the CBD oil in place for a minimum of 60 seconds. The 60 second hold allows for absorption via the blood vessels underneath your tongue – efficiently bypassing first-pass metabolism. Once 60 seconds has passed, swallow the CBD oil.
Cannabis was criminalized in various countries beginning in the 19th century. The British colonies of Mauritius banned cannabis in 1840 over concerns on its effect on Indian indentured workers; the same occurred in British Singapore in 1870. In the United States, the first restrictions on sale of cannabis came in 1906 (in District of Columbia). It was outlawed in Jamaica (then a British colony) in 1913, in South Africa in 1922, and in the United Kingdom and New Zealand in the 1920s. Canada criminalized cannabis in The Opium and Narcotic Drug Act, 1923, before any reports of the use of the drug in Canada, but eventually legalized its consumption for recreational and medicinal purposes in 2018.
To this point, CBD oil has existed in a kind of liminal space— at once an illegal drug, a legal medication, and some kind of “dietary” supplement. It’s possible this could change in the coming years, however. GW Pharmaceuticals, a U.K.-based firm, has developed a “pure CBD” medication called Epidiolex that has shown promising test results. It is currently on a fast-track to receive FDA clearance. For some patients, Epidiolex could be a miracle cure. This summer, in Wired magazine, writer Fred Vogelstein chronicled his family’s own struggles to find an effective treatment for his son’s epilepsy—including experiments with hemp oil— and the immense hurdles they overcame to gain access to Epidiolex prior to its FDA approval. The drug could be for sale on pharmacy shelves in the near future, though exactly how near is hard to say.
Industrial hemp is a versatile agricultural plant which could one day be a valuable crop option for Pennsylvania farmers. The Commonwealth of Pennsylvania has taken some important steps toward making that a reality. Following Governor Wolf’s signing of the Industrial Hemp Research Act, Number 92 in 2016, the Pennsylvania Department of Agriculture’s Industrial Hemp Research Pilot Program started issuing permits for research & growth of industrial hemp in 2017. Pennsylvania’s industrial hemp legislation was sparked by the passage of the 2014 Farm Bill, which gave federal permission for institutions of higher education or state Departments of Agriculture to research the cultivation and marketing of industrial hemp. As part of Pennsylvania’s Research Pilot Program, industrial hemp was legally grown in the Commonwealth after an 80 years hiatus. The Department of Agriculture has issued 35 research permits in the last two years to institutions of higher education and to farmers, business or individuals in contract with the Department to participate in the research of industrial hemp cultivation and marketing in Pennsylvania. In 2018, 35 research permits were issued to researchers, who cultivated industrial hemp in 25 Pennsylvania counties.
