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 has psychoactive and physiological effects when consumed. The immediate desired effects from consuming cannabis include relaxation and euphoria (the "high" or "stoned" feeling), a general alteration of conscious perception, increased awareness of sensation, increased libido and distortions in the perception of time and space. At higher doses, effects can include altered body image, auditory and/or visual illusions, pseudohallucinations and ataxia from selective impairment of polysynaptic reflexes. In some cases, cannabis can lead to dissociative states such as depersonalization and derealization.
The objectivity of scientific evaluation of the medicinal value of marijuana to date has been questioned. In the words of Hirst et al. (1998): “The ...status of cannabis has made modern clinical research almost impossible. This is primarily because of the legal, ethical and bureaucratic difficulties in conducting trials with patients. Additionally, the general attitude towards cannabis, in which it is seen only as a drug of abuse and addiction, has not helped.” In a recent editorial, the respected journal Nature (2001) stated: “Governments, including the US federal government, have until recently refused to sanction the medical use of marijuana, and have also done what they can to prevent its clinical testing. They have defended their inaction by claiming that either step would signal to the public a softening of the so-called ‘war on drugs.’... The pharmacology of cannabinoids is a valid field of scientific investigation. Pharmacologists have the tools and the methodologies to realize its considerable potential, provided the political climate permits them to do so.” Given these current demands for research on medicinal marijuana, it will be necessary to produce crops of drug types of C. sativa.

The woody core (hurds, sometimes called shives) of hemp makes remarkably good animal bedding (Fig. 28, 29). The hurds are sometimes molded into small pellets for bedding applications (Fig. 30). Such appears to be unsurpassed for horse bedding, and also make an excellent litter for cats and other pets (Fig. 31). The hurds can absorb up to five times their weight in moisture (typically 50% higher than wood shavings), do not produce dust (following initial dust removal), and are easily composted. Hemp bedding is especially suited to horses allergic to straw. In Europe, the animal bedding market is not considered important (Karus et al. 2000), but in North America there are insufficient hemp hurds available to meet market demand.
After fighting the effects of thyroid cancerfor 12 years I wanted to die. Every day. Now, please understand that these were thoughts with no actions, I was just miserable in pain.After 1 week on the CBD oil, (5 drops under the toungue 2x per day) I am a different woman. I now have hope. Some of my emotional pain is presenting as physical pain, but IT'S LEAVING MY BODY.
Hello. I have stage 4 thyroid, secondary lymphoma..And many other health issues.I use 50mg of cbd vapor oil. 5 drops with each use. Total equals 250mg, about hits per dose, three times a day. I'm also on subsys, which is fentanyl. Idk about anyone but myself, but it's helped me with pain, with sleep, and in general my moods. So I dint have anything negative to say. I just hope that with time, proper diet, low dose chemo, and some other herbal usage, that I can shirk some of the cancer eating at my body... Thanks and good luck to you all.
In addition to providing useful fibers, hemp seed also has high nutritional value. and the plant can be used to make biodegradable plastics, some fuels, and a variety of other things. Hemp foods including but not limited to hemp energy bars, hemp salad dressing,hemp milk, hemp protein shakes, hemp oil gel caps and hemp protein powder are among some of the health products being produced today.

The genus Cannabis was first classified using the "modern" system of taxonomic nomenclature by Carl Linnaeus in 1753, who devised the system still in use for the naming of species. He considered the genus to be monotypic, having just a single species that he named Cannabis sativa L. (L. stands for Linnaeus, and indicates the authority who first named the species). Linnaeus was familiar with European hemp, which was widely cultivated at the time. In 1785, noted evolutionary biologist Jean-Baptiste de Lamarck published a description of a second species of Cannabis, which he named Cannabis indica Lam. Lamarck based his description of the newly named species on plant specimens collected in India. He described C. indica as having poorer fiber quality than C. sativa, but greater utility as an inebriant. Additional Cannabis species were proposed in the 19th century, including strains from China and Vietnam (Indo-China) assigned the names Cannabis chinensis Delile, and Cannabis gigantea Delile ex Vilmorin. However, many taxonomists found these putative species difficult to distinguish. In the early 20th century, the single-species concept was still widely accepted, except in the Soviet Union where Cannabis continued to be the subject of active taxonomic study. The name Cannabis indica was listed in various Pharmacopoeias, and was widely used to designate Cannabis suitable for the manufacture of medicinal preparations.
In his office, however, Hernandez was wary of the CBD boom. He advises well-meaning parents to think twice about voyaging into the world of over-the-counter hemp oil treatments, even if their circumstances are dire. “It’s a huge gimmick that a lot of companies are using,” Hernandez said. “You don’t know what you’re getting. ... There’s a major quality problem.”
The Duquenois–Levine test is commonly used as a screening test in the field, but it cannot definitively confirm the presence of cannabis, as a large range of substances have been shown to give false positives. Despite this, it is common in the United States for prosecutors to seek plea bargains on the basis of positive D–L tests, claiming them to be conclusive, or even to seek conviction without the use of gas chromatography confirmation, which can only be done in the lab. In 2011, researchers at John Jay College of Criminal Justice reported that dietary zinc supplements can mask the presence of THC and other drugs in urine. However, a 2013 study conducted by researchers at the University of Utah School of Medicine refute the possibility of self-administered zinc producing false-negative urine drug tests.
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. 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." 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. Physiological barriers to reproduction are not known to occur within Cannabis, and plants from widely divergent sources are interfertile. 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. 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.
Short-term use increases both minor and major adverse effects. Common side effects include dizziness, feeling tired, vomiting, and hallucinations. Long-term effects of cannabis are not clear. Concerns including memory and cognition problems, risk of addiction, schizophrenia in young people, and the risk of children taking it by accident.
Today, dozens of companies produce CBD in an array of forms. CBD can be inhaled through vape pens, applied in topical salves, ingested in edibles, or swallowed in oil-based tinctures. Oil has become the dominant CBD delivery method for kids with epilepsy, since it is easy to administer and ingest, and there is no shortage of it available for sale online. There are dozens of companies boasting names like Healthy Hemp Oil, Dose of Nature, and Natural Organic Solutions, each of them selling CBD products at prices ranging from trivial to dizzyingly steep. You don’t have to look hard to find them. If you have a PayPal account and $100 to spare, you could have a vial of hemp oil delivered to your doorstep.
Right now, there’s a good chance that you don’t really know what you’re getting from any source. Testing and labeling rules vary by state, but many states that allow legal cannabis also require some kind of testing to verify that the THC and CBD levels listed on the label are accurate. However, this testing is controversial, and results can vary widely between labs, Jikomes said. A study published in March found measurable variations in test results, with some labs consistently reporting higher or lower levels of cannabinoids than others. There are no guarantees that the label accurately reflects what’s in the product. For a 2015 study published in JAMA, researchers tested 75 products purchased in San Francisco, Los Angeles and Seattle and found that only 17 percent were accurately labeled. More than half of the products contained significantly lower levels of cannabinoids than the label promised, and some of them contained only negligible amounts of the compounds. “We need to come up with ways to confidently verify the composition of cannabis products and make this information available to consumers,” Jikomes said.
A 100-gram portion of hulled hemp seeds supplies 586 calories. They contain 5% water, 5% carbohydrates, 49% total fat, and 31% protein. Hemp seeds are notable in providing 64% of the Daily Value (DV) of protein per 100-gram serving. Hemp seeds are a rich source of dietary fiber (20% DV), B vitamins, and the dietary minerals manganese (362% DV), phosphorus (236% DV), magnesium (197% DV), zinc (104% DV), and iron (61% DV). About 73% of the energy in hempseed is in the form of fats and essential fatty acids, mainly polyunsaturated fatty acids, linoleic, oleic, and alpha-linolenic acids.
