Cultivated in at least 30 countries, monikers for the hemp plant often allude to its origin or use, such as Manila hemp (abacá, Musa textilis), sisal hemp (Agave sisalana), Indian hemp (Apocynumcannabinum) and New Zealand hemp (Phormiumtenax). Worldwide, hemp seed production alone has soared from around 33,000 metric tons in the late ’90s to more than 100,000 metric tons annually between 2005 and 2011.
Although global abnormalities in white matter and grey matter are not associated with cannabis abuse, reduced hippocampal volume is consistently found. Amygdalar abnormalities are sometimes reported, although findings are inconsistent. Preliminary evidence suggests that this effect is largely mediated by THC, and that CBD may even have a protective effect.
A systematic review assessing 19 studies that evaluated premalignant or malignant lung lesions in persons 18 years or older who inhaled Cannabis concluded that observational studies failed to demonstrate statistically significant associations between Cannabis inhalation and lung cancer after adjusting for tobacco use. In the review of the published meta-analyses, the National Academies of Sciences, Engineering, and Medicine (NASEM) report concluded that there was moderate evidence of no statistical association between Cannabis smoking and the incidence of lung cancer.

Breeding for low THC cultivars in Europe has been reviewed by Bócsa (1998), Bócsa and Karus (1998), and Virovets (1996). Some researchers have claimed to have produced essentially THC-free strains, although at present no commercial cultivar seems to be 100% free of THC. THC content has proven to be more easily reduced in monoecious than in dioecious varieties. It should be possible to select THC-free strains, and there has been speculation that genetic engineering could be helpful in this regard. As a strategic economic and political tactic, France has been attempting for several years to have the European Union (EU) adopt legislation forbidding the cultivation of industrial hemp cultivars with more than 0.1% THC, which would mean that primarily French varieties would have to be cultivated in Europe. However, the Canadian government has found that some French material has proven to be excessively high in THC.
With a hypothesis that chronic marijuana use produces adverse effects on the human endocrine and reproductive systems, the association between Cannabis use and incidence of testicular germ cell tumors (TGCTs) has been examined.[12-14] Three population-based case-control studies reported an association between Cannabis use and elevated risk of TGCTs, especially nonseminoma or mixed-histology tumors.[12-14] However, the sample sizes in these studies were inadequate to address Cannabis dose by addressing associations with respect to recency, frequency, and duration of use. In a study of 49,343 Swedish men aged 19 to 21 years enrolled in the military between 1969 and 1970, participants were asked once at the time of conscription about their use of Cannabis and were followed up for 42 years. This study found no evidence of a significant relation between “ever” Cannabis use and the development of testicular cancer, but did find that “heavy” Cannabis use (more than 50 times in a lifetime) was associated with a 2.5-fold increased risk. Limitations of the study were that it relied on indirect assessment of Cannabis use; and no information was collected on Cannabis use after the conscription-assessment period or on whether the testicular cancers were seminoma or nonseminoma subtypes. These reports established the need for larger, well-powered, prospective studies, especially studies evaluating the role of endocannabinoid signaling and cannabinoid receptors in TGCTs.
Due to almost a century of misinformation about Cannabis, the distinction between Cannabis and its two primary species — hemp and marijuana — has become unclear to the many and some even consider the three plants to be one in the same. Because of this, the three terms are often used interchangeably, which has created difficulties when understanding the usage and benefits of Hemp vs Marijuana and Cannabis in general.
It sounds like the title of a children’s book, but like so much else that you learned in kindergarten, it’s true. Everyone’s body is different – but everyone’s endocannabinoid system is really unique. For reasons we don’t fully understand, receptors in the endocannabinoid system don’t respond predictably to cannabinoids from person to person. This lack of a predictable response makes standard dosing tricky.
One of the most curious uses of hemp is as a fence to prevent pollen transfer in commercial production of seeds. Isolation distances for ensuring that seeds produced are pure are considerable for many plants, and often impractical. At one point in the 1980s, the only permitted use of hemp in Germany was as a fence or hedge to prevent plots of beets being used for seed production from being contaminated by pollen from ruderal beets. The high and rather inpenetrable hedge that hemp can produce was considered unsurpassed by any other species for the purpose. As well, the sticky leaves of hemp were thought to trap pollen. However, Saeglitz et al. (2000) demonstrated that the spread of beet pollen is not effectively prevented by hemp hedges. Fiber (i.e. tall) cultivars of hemp were also once used in Europe as wind-breaks, protecting vulnerable crops against wind damage. Although hemp plants can lodge, on the whole very tall hemp is remarkably resistant against wind.
THC and its major (inactive) metabolite, THC-COOH, can be measured in blood, urine, hair, oral fluid or sweat using chromatographic techniques as part of a drug use testing program or a forensic investigation of a traffic or other criminal offense. The concentrations obtained from such analyses can often be helpful in distinguishing active use from passive exposure, elapsed time since use, and extent or duration of use. These tests cannot, however, distinguish authorized cannabis smoking for medical purposes from unauthorized recreational smoking. Commercial cannabinoid immunoassays, often employed as the initial screening method when testing physiological specimens for marijuana presence, have different degrees of cross-reactivity with THC and its metabolites. Urine contains predominantly THC-COOH, while hair, oral fluid and sweat contain primarily THC. Blood may contain both substances, with the relative amounts dependent on the recency and extent of usage.
Cannabis (/ˈkænəbɪs/) is a genus of flowering plants in the family Cannabaceae. The number of species within the genus is disputed. Three species may be recognized: Cannabis sativa, Cannabis indica, and Cannabis ruderalis; C. ruderalis may be included within C. sativa; or all three may be treated as subspecies of a single species, C. sativa. The genus is widely accepted as being indigenous to and originating from Central Asia, with some researchers also including upper South Asia in its origin.
Hi…I read your statement about hemp being a cream that takes pain away. Living in Oregon there’s no talk about “hemp” but I don’t doubt your experience with it..and I’m wondering where you found it..so that maybe I can get a jar of it and see if it would help my aches and pains….I would really appreciate your response…and thanks for your “reply” that motivated me to write to you..
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).
As I research more I am disgusted with how we have all been deceived. I feel confident now with being able to research things on our own, at any moment in time, we can begin to take back our world. In the early 30’s one of the great media conspiracies unfolded. Publisher William Hearst, Dupont, the petroleum interests, the cotton lobby, the bankers and some ignorant politicians lead a crusade to ban hemp to line their pockets. Hemp can revolutionize our society. Please research and pass on!
The DEA isn’t the only government agency scrutinizing CBD vendors. To fend off the FDA, hemp oil companies contend their wares are not drugs but “dietary supplements.” Despite the suggestive “meds” in the company’s name, HempMedsPx is careful to note on its web site, “Although some of our founders are medical professionals, we cannot make medical claims about the benefits of our products.” Others are not quite so nuanced in their marketing. The internet is flooded with CBD products claiming to treat everything from seizures to arthritis to skin conditions and other maladies.
Indoor marijuana grows provide the most control over growing conditions. With a simple setup including a tent, proper lighting, and an air circulation system, home marijuana growers can produce consistent yields. Both soil and hydro systems can be utilized for indoor marijuana grows. Soil setups are generally cheaper and more forgiving, but hydro systems tend to be more common.
In addition, both plant-derived and endogenous cannabinoids have been studied for anti-inflammatory effects. A mouse study demonstrated that endogenous cannabinoid system signaling is likely to provide intrinsic protection against colonic inflammation. As a result, a hypothesis that phytocannabinoids and endocannabinoids may be useful in the risk reduction and treatment of colorectal cancer has been developed.[27-30]

As of March 2016, more than half of the 50 states have laws that allow for some hemp production, according to this chart. Yet, many states, such as California, where Jungmaven is based, will only allow for industrial hemp cultivation when federal law coincides with state law. That is, when Congress passes a bill permitting industrial hemp across the US. Currently, Jungmann imports his hemp from China, but he’s confident Congress will pass the bill legalizing industrial farming of hemp in July.
Medical cannabis, or medical marijuana, can refer to the use of cannabis and its cannabinoids to treat disease or improve symptoms; however, there is no single agreed-upon definition. The rigorous scientific study of cannabis as a medicine has been hampered by production restrictions and other federal regulations. There is limited evidence suggesting cannabis can be used to reduce nausea and vomiting during chemotherapy, to improve appetite in people with HIV/AIDS, and to treat chronic pain and muscle spasms. Its use for other medical applications is insufficient for conclusions about safety or efficacy.
In December 2012, the U.S. state of Washington became the first state to officially legalize cannabis in a state law (Washington Initiative 502) (but still illegal by federal law), with the state of Colorado following close behind (Colorado Amendment 64). On January 1, 2013, the first marijuana "club" for private marijuana smoking (no buying or selling, however) was allowed for the first time in Colorado. The California Supreme Court decided in May 2013 that local governments can ban medical marijuana dispensaries despite a state law in California that permits the use of cannabis for medical purposes. At least 180 cities across California have enacted bans in recent years.
Anybody can apply to grow industrial hemp except one who has been convicted of a felony for controlled substance in the past 10 years. Anyone who has been issued a hemp license can grow on the approved growing areas indicated on their application. Licensed industrial hemp can be grown anywhere, indoor or outdoor. The research pilot program allows for any size growing area, from large acre lots to small garden sizes. There are no zoning requirements for a hemp license.
Based on studies of sex reversal in hemp, it was first reported by K. Hirata in 1924 that an XY sex-determination system is present. At the time, the XY system was the only known system of sex determination. The X:A system was first described in Drosophila spp in 1925. Soon thereafter, Schaffner disputed Hirata's interpretation, and published results from his own studies of sex reversal in hemp, concluding that an X:A system was in use and that furthermore sex was strongly influenced by environmental conditions.
The health consequences of cannabis use in developing countries are largely unknown beacuse of limited and non-systematic research, but there is no reason a priori to expect that biological effects on individuals in these populations would be substantially different to what has been observed in developed countries. However, other consequences might be different given the cultural and social differences between countries.
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.”
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.
