In the EU and Canada, hemp has often been grown as a dual-purpose crop, i.e. for both fiber and oilseed. In France, dual purpose hemp is typically harvested twice—initially the upper seed-bearing part of the stems is cut and threshed with a combine, and subsequently the remaining stems are harvested. Growing hemp to the stage that mature seeds are present compromises the quality of the fiber, because of lignification. As well, the hurds become more difficult to separate. The lower quality fiber, however, is quite utilizable for pulp and non-woven usages.
Finally, the entire marijuana flower structure is coated with resinous crystals called trichomes. Trichomes are translucent, mushroom-like glands that form on the entire flowering structure and even the stems of the marijuana plant. These bulb-shaped glands secrete the rich, aromatic essential oils that give cannabis its smells and flavors. Trichomes also contain cannabinoids.
Until recent times, the cultivation of hemp primarily as an oilseed was largely unknown, except in Russia. Today, it is difficult to reconstruct the type of plant that was grown there as an oilseed, because such cultivation has essentially been abandoned. Oilseed hemp cultivars in the modern sense were not available until very recently, but some land races certainly were grown specifically for seeds in Russia. Dewey (1914) gave the following information: “The short oil-seed hemp with slender stems, about 30 inches high, bearing compact clusters of seeds and maturing in 60 to 90 days, is of little value for fiber production, but the experimental plants, grown from seed imported from Russia, indicate that it may be valuable as an oil-seed crop to be harvested and threshed in the same manner as oil-seed flax.” Most hemp oilseed in Europe is currently obtained from so-called “dual usage” plants (employed for harvest of both stem fiber and seeds, from the same plants). Of the European dual-usage cultivars, ‘Uniko B’ and ‘Fasamo’ are particularly suited to being grown as oilseeds. Very recently, cultivars have been bred specifically for oilseed production. These include ‘Finola,’ formerly known as ‘Fin-314’ (Fig. 6) and ‘Anka’ (Fig. 7), which are relatively short, little-branched, mature early in north-temperate regions, and are ideal for high-density planting and harvest with conventional equipment. Dewey (1914) noted that a Turkish narcotic type of land race called “Smyrna” was commonly used in the early 20th century in the US to produce birdseed, because (like most narcotic types of Cannabis) it is densely branched, producing many flowers, hence seeds. While oilseed land races in northern Russia would have been short, early-maturing plants in view of the short growing season, in more southern areas oilseed landraces likely had moderate height, and were spaced more widely to allow abundant branching and seed production to develop. Until Canada replaced China in 1998 as a source of imported seeds for the US, most seeds used for various purposes in the US were sterilized and imported from China. Indeed, China remains the largest producer of hempseed. We have grown Chinese hemp land races, and these were short, branched, adapted to a very long growing season (i.e. they come into flower very slowly in response to photoperiodic induction of short days in the fall), and altogether they were rather reminiscent of Dewey’s description of Smyrna. Although similar in appearance to narcotic strains of C. sativa, the Chinese land races we grew were in fact low in intoxicating constituents, and it may well be that what Dewey thought was a narcotic strain was not. Although some forms of C. sativa have quite large seeds, until recently oilseed forms appear to have been mainly selected for a heavy yield of seeds, usually recognizable by abundant branching. Such forms are typically grown at lower densities than hemp grown only for fiber, as this promotes branching, although it should be understood that the genetic propensity for branching has been selected. Percentage or quality of oil in the seeds does not appear to have been important in the past, although selection for these traits is now being conducted. Most significantly, modern selection is occurring with regard to mechanized harvesting, particularly the ability to grow in high density as single-headed stalks with very short branches bearing considerable seed.
Professors William Emboden, Loran Anderson, and Harvard botanist Richard E. Schultes and coworkers also conducted taxonomic studies of Cannabis in the 1970s, and concluded that stable morphological differences exist that support recognition of at least three species, C. sativa, C. indica, and C. ruderalis. For Schultes, this was a reversal of his previous interpretation that Cannabis is monotypic, with only a single species. According to Schultes' and Anderson's descriptions, C. sativa is tall and laxly branched with relatively narrow leaflets, C. indica is shorter, conical in shape, and has relatively wide leaflets, and C. ruderalis is short, branchless, and grows wild in Central Asia. This taxonomic interpretation was embraced by Cannabis aficionados who commonly distinguish narrow-leafed "sativa" strains from wide-leafed "indica" strains.
Even as the research proceeds, thousands of people are using CBD as medicine. A British pharmaceutical company, GW Pharma, has developed two CBD drugs: Sativex, which contains a 1-to-1 ratio of CBD and THC, and Epidiolex, which is pure CBD. The former is prescribed for the painful muscle spasms that occur in multiple sclerosis, while the latter is aimed at childhood seizures. Sativex is not available in the United States, but it is approved in 29 other countries, including Canada, England and Israel.
A colleague of Mechoulam’s, Marc Feldman at Imperial College, London, tested CBD on mice that had a version of rheumatoid arthritis. He found that CBD reduced the mice’s inflammation by 50% at the right dosage. Cardiologists working with the mice at Hebrew University have found that a dosage of CBD immediately following a heart attack can reduce infarct size by about 66%.
The authors compared this patient's CT scan with one from a cigarette smoker. The second scan illustrated a strikingly different pattern of emphysema, with smaller panacinar bullae in a uniformly distributed centrilobular pattern. An explanation of the differences in lung findings due to cannabis and cigarettes would take into account a number of variables. Cannabis smoking requires longer inhalation and breath-holding time. Inhaled cannabis through a bong is at a higher temperature. A cannabis joint, which lacks a filter, also has a greater delivery of the drug.
The gateway effect may appear due to social factors involved in using any illegal drug. Because of the illegal status of cannabis, its consumers are likely to find themselves in situations allowing them to acquaint with individuals using or selling other illegal drugs. Utilizing this argument some studies have shown that alcohol and tobacco may additionally be regarded as gateway drugs; however, a more parsimonious explanation could be that cannabis is simply more readily available (and at an earlier age) than illegal hard drugs. In turn alcohol and tobacco are easier to obtain at an earlier point than is cannabis (though the reverse may be true in some areas), thus leading to the "gateway sequence" in those individuals since they are most likely to experiment with any drug offered.

These mounting developments in the elicited a problem amongst cannabis cultivators across the US: decades of selectively breeding cannabis to achieve the maximum amount of THC for a strong high reduced the overall preponderance of CBD in cultivars across the country to trace lows. Essentially, CBD had been selectively bred out of existence across the country.
If medical marijuana is illegal in a given state, THC levels determine whether a CBD product is illicit or not. In most places, the limit is extremely low. We’re talking under 1 percent THC, with some states opting for a cap as low as 0.3 percent. In this case, the only source that would work is hemp, and CBD products will, therefore, be hemp-derived.
Figure 2. Receptor Systems Involved in CBD’s Potential Therapeutic Applications. CBD interacts, either directly or indirectly, with many different receptor systems in the brain. It indirectly influences the major cannabinoid receptor in the brain by decreasing THC’s ability to stimulate this receptor. It also interacts with a variety of other receptors. A subset of these are shown here. Each red shape represents a different brain receptor that might be found on a neuron. Some of the potential therapeutic applications associated with CBD’s interaction with each receptor system are listed below each receptor.
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. Hemp has lower concentrations of THC and higher concentrations of cannabidiol (CBD), which decreases or eliminates its psychoactive effects. 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.
We believe the perfect ratio depends on your tolerance for the psychoactive effects of THC. It also depends on the symptoms youre treating and the time of day. For example, one might take a high CBD, low THC ratio in the morning for anxiety relief without feelings of impairment (like the 18:1), and a more balanced ratio of CBD-to-THC at night to help with sleep (like the 2:1 or 1:1). #thisisCBD #cbd #CareByDesign
^ Juliet Eilperin (February 11, 2013), "'Good seed' versus 'evil weed': Hemp activists eye legalization", The Washington Post – via The Japan Times Online, [A] couple of factors — the high taxes the federal government imposed on growing hemp in the late 1930s and again in the early '50s, and then the DEA's interpretation of the 1970 law — made producing hemp nearly impossible. Since the DEA only grants permits in rare instances and demands costly, elaborate security precautions, large-scale hemp growing in the United States is not viable.
