In Canada, the methodology used for analyses and sample collection for THC analysis of hemp plantings is standardized (at the Health Canada/Therapeutics Program/Hemp web site at www.hc-sc.gc.ca/hpb-dgps/therapeut/htmleng/hemp.html, see “Industrial Hemp Technical Manual” for procedures on sampling plant materials and chemical procedures for determining THC levels). The regulations require that one of the dozen independent laboratories licensed for the purpose conduct the analyses and report the results to Health Canada. Sample collection is also normally carried out by an independent authorized firm. The Canadian system of monitoring THC content has rigidly limited hemp cultivation to cultivars that consistently develop THC levels below 0.3%.
Cannabidiol is currently a class B1 controlled drug in New Zealand under the Misuse of Drugs Act. It is also a prescription medicine under the Medicines Act. In 2017 the rules were changed so that anyone wanting to use it could go to the Health Ministry for approval. Prior to this, the only way to obtain a prescription was to seek the personal approval of the Minister of Health.
So-called “pure hybrids,” while oxymoronic in name, indicate marijuana strains that are believed to offer a perfect blend or balance of sativa’s energizing and indica’s sedating effects. Other hybrid strains of cannabis tend to place the emphasis on one end of the spectrum or the other. These are called “sativa-dominant” or “indica-dominant,” accordingly.
CBD products that don't contain THC fall outside the scope of the U.S. Drug Enforcement Agency's (DEA) Controlled Substances Act, which means CBD products are legal to sell and consume as long as they don't have THC. That's likely one of the reasons why CBD products, including CBD oil, are becoming more socially acceptable and increasingly popular. In 2016, Forbes reported that CBD products are expected to be a $2.2 billion industry by 2020.
Following an 1836–1840 travel in North Africa and the Middle East, French physician Jacques-Joseph Moreau wrote on the psychological effects of cannabis use; he was a member of Paris' Club des Hashischins. In 1842, Irish physician William Brooke O'Shaughnessy, who had studied the drug while working as a medical officer in Bengal with the East India company, brought a quantity of cannabis with him on his return to Britain, provoking renewed interest in the West. Examples of classic literature of the period featuring cannabis include Les paradis artificiels (1860) by Charles Baudelaire and The Hasheesh Eater (1857) by Fitz Hugh Ludlow.
Australia's National Cannabis Prevention and Information Centre (NCPIC) states that the buds (flowers) of the female cannabis plant contain the highest concentration of THC, followed by the leaves. The stalks and seeds have "much lower THC levels". The UN states that leaves can contain ten times less THC than the buds, and the stalks one hundred times less THC.
The question of whether heteromorphic sex chromosomes are indeed present is most conveniently answered if such chromosomes were clearly visible in a karyotype. Cannabis was one of the first plant species to be karyotyped; however, this was in a period when karyotype preparation was primitive by modern standards (see History of Cytogenetics). Heteromorphic sex chromosomes were reported to occur in staminate individuals of dioecious "Kentucky" hemp, but were not found in pistillate individuals of the same variety. Dioecious "Kentucky" hemp was assumed to use an XY mechanism. Heterosomes were not observed in analyzed individuals of monoecious "Kentucky" hemp, nor in an unidentified German cultivar. These varieties were assumed to have sex chromosome composition XX. According to other researchers, no modern karyotype of Cannabis had been published as of 1996. Proponents of the XY system state that Y chromosome is slightly larger than the X, but difficult to differentiate cytologically.
Consumers report using CBD for a huge variety of health and wellness reasons, but a lot more research is needed to determine which symptoms and ailments it works best for. Currently, there are more than 40 clinical trials enrolling patients to examine the effectiveness of CBD for a variety of diseases, including substance use disorder, chronic pain, post-traumatic stress disorder (PTSD), depression, schizophrenia, and many others. Most importantly, CBD is incredibly safe, and not addictive. Even young children can tolerate daily doses of up to twenty milligrams (20 mg) per kilogram (1 kg) of body weight (for a 175 pound adult, that’s more than 1,500 mg). The most common side effect of high-dose CBD is sleepiness.
The Spaniards brought hemp to the Americas and cultivated it in Chile starting about 1545. Similar attempts were made in Peru, Colombia, and Mexico, but only in Chile did the crop find success. In July 1605, Samuel Champlain reported the use of grass and hemp clothing by the (Wampanoag) people of Cape Cod and the (Nauset) people of Plymouth Bay told him they harvested hemp in their region where it grew wild to a height of 4 to 5 ft.  In May 1607, "hempe" was among the crops Gabriel Archer observed being cultivated by the natives at the main Powhatan village, where Richmond, Virginia is now situated; and in 1613, Samuell Argall reported wild hemp "better than that in England" growing along the shores of the upper Potomac. As early as 1619, the first Virginia House of Burgesses passed an Act requiring all planters in Virginia to sow "both English and Indian" hemp on their plantations. The Puritans are first known to have cultivated hemp in New England in 1645.
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.
I purchased this for my sons. One has a tight lower back (6 years) due to an over active core, I used it after he did stretches, and his back has no more pain. I use it daily, for his body re-learn; no pain. My other son had an injured shoulder (surgery) and elbow nerve issues. After his stretches, I use it on him. He has said that his arm feels better, not at 100% yet, but I highly recommend. I myself have used this on my lower calf, it was bothering me, and I wanted to try it out, my calf feels better.

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. 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. Few high quality studies have been performed on the long-term effects of cannabis on cognition, and results were generally inconsistent. Furthermore, effect sizes of significant findings were generally small. One review concluded that, although most cognitive faculties were unimpaired by cannabis use, residual deficits occurred in executive functions. 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. 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. Cannabis users demonstrated increased activity in task-related brain regions, consistent with reduced processing efficiency.
After seasonal harvests of specific cultivars, these high-CBD hemp crops are put through a specialized solvent-free extraction process to yield a hemp oil that is naturally high in cannabidiol. This pure hemp extract is then tested for safety, quality, and cannabinoid content before being exported to our processing facilities in the United States. Importing any cannabis or hemp product into the United States is a complicated and serious task, so we leave nothing to chance before our high-CBD hemp oil makes its journey across the Atlantic Ocean.

Hemp is grown in temperate zones as an annual cultivated from seed and can reach a height of up to 5 metres (16 feet). Crops grow best in sandy loam with good drainage and require average monthly rainfall of at least 65 mm (2.5 inches) throughout the growing season. Crops cultivated for fibre are densely sowed and produce plants averaging 2–3 metres (6–10 feet) tall with almost no branching. Plants grown for oilseed are planted farther apart and are shorter and many-branched. The slender stalks are hollow except at the tip and base. The leaves are compound with palmate shape, and the flowers are small and greenish yellow. Seed-producing flowers form elongate, spikelike clusters growing on the pistillate, or female, plants. Pollen-producing flowers form many-branched clusters on staminate, or male, plants. Maximum yield and quality are obtained by harvesting soon after the plants reach maturity, indicated by the full blossoms and freely shedding pollen of the male plants. Although sometimes pulled up by hand, plants are more often cut off about 2.5 cm (1 inch) above the ground.
Subsequent studies were carried out in different countries, which confirmed the results found in the Zammit et al. (2002) study, showing that those clinically dependent on cannabis by 18 years of age had an increased risk of later developing psychotic symptoms (Fergusson, Horwood, & Swain-Campbell, 2003). Cannabis users were also more likely to develop schizophreniform disorder (Arseneault et al., 2002), and the dose–response relationship found in the first study was confirmed (Henquet et al., 2005).
In 1924, Russian botanist D.E. Janichevsky concluded that ruderal Cannabis in central Russia is either a variety of C. sativa or a separate species, and proposed C. sativa L. var. ruderalis Janisch, and Cannabis ruderalis Janisch, as alternative names. In 1929, renowned plant explorer Nikolai Vavilov assigned wild or feral populations of Cannabis in Afghanistan to C. indica Lam. var. kafiristanica Vav., and ruderal populations in Europe to C. sativa L. var. spontanea Vav. In 1940, Russian botanists Serebriakova and Sizov proposed a complex classification in which they also recognized C. sativa and C. indica as separate species. Within C. sativa they recognized two subspecies: C. sativa L. subsp. culta Serebr. (consisting of cultivated plants), and C. sativa L. subsp. spontanea (Vav.) Serebr. (consisting of wild or feral plants). Serebriakova and Sizov split the two C. sativa subspecies into 13 varieties, including four distinct groups within subspecies culta. However, they did not divide C. indica into subspecies or varieties.
The 1000mg potency would be best. The recommended dose is 1/2 the dropper 1-2 times a day. If you do not get the desired relief within a couple days you can slowly increase the dose as that is not harmful and essentially adds to the potency being absorbed. Our products metabolize differently in each individual; we do have customers whom take it in the morning, afternoon, and evening as they find that is what works best for them. The topical ointment may be beneficial as well as it contains menthol so it gives an instant relief while the CBD absorbs into the skin.
Historically, so many different applications have been found for hemp’s stalk. In a 1938 Popular Mechanics article, hemp was stated to be the next ‘billion dollar crop’, as it praised its bafflingly strong fibers. The magazine found there to be more than 25,000 industrial uses for hemp. Applications of hemp stalk include apparel, bags, rope, netting, canvas, and carpet.
We have seen a huge amount of children with epilepsy that has benefited enormous from getting high CBD rich cannabis as treatment. Many children like Charlotte Figi, who was having 300 grand mal seizures a week and Jayden and his dad Jason, who also decided to try cannabis with high CBD as a treatment option. There are loads of people reporting about huge benefits from using CBD/THC for treating epileptic seizures. And many share their stories on channels like Youtube and Facebook for everybody to learn from their experiences and now many studies have been done and are being done on this as well.
Yet, even with this progress, hemp businesses seem to face difficulty expanding in the US as they face challenges in traditional marketing and sales approaches. According to a case study done by Forbes, hemp businesses and startups have had difficulty marketing and selling non-psychoactive hemp products, as some online advertising platforms and financial institutions do not distinguish between hemp and marijuana.
Cannabis sativa is an annual wind-pollinated plant, normally dioecious and dimorphic, although sometimes monoecious (mostly in several modern European fiber cultivars). Figure 2 presents the basic morphology of the species. Some special hybrids, obtained by pollinating females of dioecious lines with pollen from monoecious plants, are predominantly female (so-called “all-female,” these generally also produce some hermaphrodites and occasional males). All-female lines are productive for some purposes (e.g. they are very uniform, and with very few males to take up space they can produce considerable grain), but the hybrid seed is expensive to produce. Staminate or “male” plants tend to be 10%–15% taller and are less robust than the pistillate or “female” (note the comparatively frail male in Fig. 3). So prolific is pollen production that an isolation distance of about 5 km is usually recommended for generating pure-bred foundation seed. A “perigonal bract” subtends each female flower, and grows to envelop the fruit. While small, secretory, resin-producing glands occur on the epidermis of most of the above-ground parts of the plant, the glands are very dense and productive on the perigonal bracts, which are accordingly of central interest in marijuana varieties. The root is a laterally branched taproot, generally 30–60 cm deep, up to 2.5 m in loose soils, very near the surface and more branched in wet soils. Extensive root systems are key to the ability of hemp crops to exploit deep supplies of nutrients and water. The stems are erect, furrowed, and usually branched, with a woody interior, and may be hollow in the internodes. Although the stem is often woody, the species is frequently referred to as a herb or forb. Plants vary enormously in height depending on genetic constitution and environment (Fig. 4), but are typically 1–5 m (heights of 12 m or more in cultivation have been claimed).
"Cannabinoids have been found to have antioxidant properties, unrelated to NMDA receptor antagonism. This new found property makes cannabinoids useful in the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV dementia.
Hemp is a sustainable crop as it grows more vigorously than other plants. It requires less water, pesticides, herbicides, and fertilizers. Hemp has over 25,000 known uses and has proven to be friendly to the environment, hence favorable on an industrial scale. Hemp can be used in making products such as clothing, shoes, animal food, ropes, textiles, bio-fuel, and bio-plastics. Its stalks can even be used as alternative building materials.
