Can CBD oil help anxiety? Cannabidiol (CBD) is a chemical occurring in cannabis plants. It is possible to add CBD oil to food, and an increasing amount of evidence suggests that it may improve mental health, particularly anxiety. It does not seem to have adverse side effects, but CBD oil is illegal in some states. Learn more about CBD oil here. Read now
Heavy, long-term exposure to marijuana may have biologically based physical, mental, behavioral and social health consequences and may be "associated with diseases of the liver (particularly with co-existing hepatitis C), lungs, heart, and vasculature". It is recommended that cannabis use be stopped before and during pregnancy as it can result in negative outcomes for both the mother and baby. However, maternal use of marijuana during pregnancy does not appear to be associated with low birth weight or early delivery after controlling for tobacco use and other confounding factors. A 2014 review found that while cannabis use may be less harmful than alcohol use, the recommendation to substitute it for problematic drinking was premature without further study. Various surveys conducted between 2015 and 2019 found that many users of cannabis substitute it for prescription drugs (including opioids), alcohol, and tobacco; most of those who used it in place of alcohol or tobacco either reduced or stopped their intake of the latter substances.
Cannabinoid agonists produce many effects beyond those mediated directly on receptors, including anti-inflammatory effects and interactions with various other neurotransmitter systems (previously reviewed (Russo 2006a). Briefly stated, THC effects in serotonergic systems are widespread, including its ability to decrease 5-hydroxytryptamine (5-HT) release from platelets (Volfe et al 1985), increase its cerebral production and decrease synaptosomal uptake (Spadone 1991). THC may affect many mechanisms of the trigeminovascular system in migraine (Akerman et al 2003; Akerman et al 2004; Akerman et al 2007; Russo 1998; Russo 2001). Dopaminergic blocking actions of THC (Müller-Vahl et al 1999) may also contribute to analgesic benefits.
CBD has powerful effects on the liver as well. Have you ever had a prescription that warns you not to take the medicine along with grapefruit? That’s because grapefruit inhibits certain drug-metabolizing enzymes in your liver, resulting in much higher levels of your medication in your bloodstream. CBD does the same thing, so it is wise to discuss your medication regimen with a doctor or pharmacist before engaging in CBD therapy.
Marijuana is the most popular illicit drug in the world, for no reason other than the fact that it produces a psychoactive chemical called tetrahydrocannabinol. Still, recreational marijuana use, which involves pursuing the euphoric sensations produced by cannabis consumption, is steadily becoming more and more legal, both in the United States and abroad.
A clinical endocannabinoid deficiency has been postulated to be operative in certain treatment-resistant conditions (Russo 2004), and has received recent support in findings that anandamide levels are reduced over controls in migraineurs (Sarchielli et al 2006), that a subset of fibromyalgia patients reported significant decreased pain after THC treatment (Schley et al 2006), and the active role of the ECS in intestinal pain and motility in irritable bowel syndrome (Massa and Monory 2006) wherein anecdotal efficacy of cannabinoid treatments have also been claimed.
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.
Cognitive effects of cannabis have been reviewed (Russo et al 2002; Fride and Russo 2006), but less study has occurred in therapeutic contexts. Effects of chronic heavy recreational cannabis usage on memory abate without sequelae after a few weeks of abstinence (Pope et al 2001). Studies of components of the Halstead-Reitan battery with Sativex in neuropathic pain with allodynia have revealed no changes vs placebo (Nurmikko et al 2007), and in central neuropathic pain in MS (Rog et al 2005), 4 of 5 tests showed no significant differences. While the Selective Reminding Test did not change significantly on Sativex, placebo patients displayed unexpected improvement.
The mosaic of laws that govern CBD legality across the globe varies just as much as the legislation across the US. Generally, CBD extract is legal in most countries, but what makes it illegal is where and what it’s extracted from. Most Group of 20 (G20) countries allow CBD extracted from industrial hemp, but not CBD extracted from whole-plant marijuana. Note, however, the differences between the two. Legislation regarding international travel with CBD also varies among countries. For the foreseeable future, the best practice would be to search online, or contact the respective embassies or consulates, before traveling to determine whether your CBD is safe and legal.
In 1988, the first cannabinoid receptor was identified (CB1) (Howlett et al 1988) and in 1993, a second was described (CB2) (Munro et al 1993). Both are 7-domain G-protein coupled receptors affecting cyclic-AMP, but CB1 is more pervasive throughout the body, with particular predilection to nociceptive areas of the central nervous system and spinal cord (Herkenham et al 1990; Hohmann et al 1999), as well as the peripheral nervous system (Fox et al 2001; Dogrul et al 2003) wherein synergy of activity between peripheral and central cannabinoid receptor function has been demonstrated (Dogrul et al 2003). CB2, while commonly reported as confined to lymphoid and immune tissues, is also proving to be an important mediator for suppressing both pain and inflammatory processes (Mackie 2006). Following the description of cannabinoid receptors, endogenous ligands for these were discovered: anandamide (arachidonylethanolamide, AEA) in 1992 in porcine brain (Devane et al 1992), and 2-arachidonylglycerol (2-AG) in 1995 in canine gut tissue (Mechoulam et al 1995) (Figure 1). These endocannabinoids both act as retrograde messengers on G-protein coupled receptors, are synthesized on demand, and are especially active on glutamatergic and GABA-ergic synapses. Together, the cannabinoid receptors, their endogenous ligands (“endocannabinoids”) and metabolizing enzymes comprise the endocannabinoid system (ECS) (Di Marzo et al 1998), whose functions have been prosaically termed to be “relax, eat, sleep, forget and protect” (p. 528). The endocannabinoid system parallels and interacts at many points with the other major endogenous pain control systems: endorphin/enkephalin, vanilloid/transient receptor potential (TRPV), and inflammatory. Interestingly, our first knowledge of each pain system has derived from investigation of natural origin analgesic plants, respectively: cannabis (Cannabis sativa, C. indica) (THC, CBD and others), opium poppy (Papaver somniferun) (morphine, codeine), chile peppers (eg, Capsicum annuum, C. frutescens, C. chinense) (capsaicin) and willow bark (Salix spp.) (salicylic acid, leading to acetylsalicylic acid, or aspirin). Interestingly, THC along with AEA and 2-AG, are all partial agonists at the CB1 receptor. Notably, no endocannabinoid has ever been administered to humans, possibly due to issues of patentability and lack of commercial feasibility (Raphael Mechoulam, pers comm 2007). For an excellent comprehensive review of the endocannabinoid system, see Pacher et al (2006), while Walker and Huang have provided a key review of antinociceptive effects of cannabinoids in models of acute and persistent pain (Walker and Huang 2002).
"Skin dryness and itchiness, in particular, are very serious problems in atopic dermatitis, which often lead to additional complications, such as opportunistic infections. In any event, it seems that the reduction of atopic symptomology observed in this study is a direct result of ingested hempseed oil. These preliminary results confirm anecdotal observations of improved skin quality after ingesting modest amounts of hempseed oil on a daily basis over a relatively short period of time."
Oh, and that ideal ratio of omegas? Researchers in Spain say that composition makes hemp oil high in polyunsaturated fatty acids (PUFAs). A high ratio of PUFAs to saturated fats has been linked to reductions in cholesterol levels and atherosclerosis (hardening and narrowing of the arteries). That suggests hemp oil may have the potential to help prevent heart disease, according to the study authors. But again, none of this has been tested in people.
Cannabis lowers the pressure in the eye that causes optic nerve damage leading to glaucoma. Research has shown conclusively that marijuana users experience lower internal eye pressure while the body metabolizes THC. However, the psychoactive side effects of using THC to treat glaucoma make cannabis a nonviable medication for most people with the disease.
Also high in fiber, hemp seeds are more digestible than any other high-protein food, including meat, cheese, eggs, human milk, or cows’ milk. They’re high in antioxidants, and minerals like iron, zinc and copper as well as calcium, magnesium, potassium, carotene, thiamin (vitamin B1), riboflavin (vitamin B2), vitamin B6 and vitamin E. If that’s not enough, there’s also chlorophyll, sulfur, phosphorus, phospholipids, and phytosterols.
Cannabis use is associated with increased recruitment of task-related areas, such as the dorsolateral prefrontal cortex, which is thought to reflect compensatory activity due to reduced processing efficiency. Cannabis use is also associated with downregulation of CB1 receptors. The magnitude of down regulation is associated with cumulative cannabis exposure, and is reversed after one month of abstinence. There is limited evidence that chronic cannabis use can reduce levels of glutamate metabolites in the human brain.
The etymology is uncertain but there appears to be no common Proto-Indo-European source for the various forms of the word; the Greek term kánnabis is the oldest attested form, which may have been borrowed from an earlier Scythian or Thracian word. Then it appears to have been borrowed into Latin, and separately into Slavic and from there into Baltic, Finnish, and Germanic languages. Following Grimm's law, the "k" would have changed to "h" with the first Germanic sound shift, after which it may have been adapted into the Old English form, hænep. However, this theory assumes that hemp was not widely spread among different societies until after it was already being used as a psychoactive drug, which Adams and Mallory (1997) believe to be unlikely based on archaeological evidence. Barber (1991) however, argued that the spread of the name "kannabis" was due to its historically more recent drug use, starting from the south, around Iran, whereas non-THC varieties of hemp are older and prehistoric. Another possible source of origin is Assyrian qunnabu, which was the name for a source of oil, fiber, and medicine in the 1st millennium BC.
CBD, or cannabidiol, is a cannabinoid found in the hemp plant. As we’ve discovered more about the human species as well as the plants that we’ve learned of the immense health value that CBD brings to the table. It has quickly become a staple supplement for millions who seek a natural alternative to dangerous pharmaceuticals, alien to nature’s perfect remedies.
Hemp is completely different from marijuana in its function, cultivation and application. But these differences didn’t stop our political leaders from getting confused and accidentally grouping all Cannabis species as a Schedule I Drug and banning it in 1970 under the Controlled Substances Act. Even after 45 years, the government still seems to have some confusion in distinguishing the two plants. Although legislation is being made, progress has been slow.In its application, hemp and marijuana serve completely different purposes. Marijuana, as it is widely known, is used for medicinal or recreational purposes. Hemp is used in variety of other applications that marijuana couldn’t possibly be used in. These include healthy dietary supplements, skin products, clothing, and accessories. Overall, hemp is known to have over 25,000 possible applications.
The market is rife with misinformation even when CBD is sold as a relatively simple oil or supplement. When it’s squirted into a latte or baked into a cookie, CBD’s uses and effects get even more opaque. The chemical’s loudest advocates make health claims far beyond the current scientific evidence, and its harshest critics often dismiss the compound entirely as just another snake oil in America’s long tradition of health scams. Journalists are starting to get a handle on what CBD actually does and what is actually known about it, but along with researchers and regulators, we’re still playing catch-up when it comes to the people who have pushed the compound into what feels like mainstream overnight success: entrepreneurs.
Tocopherols. Tocopherols are major antioxidants in human serum. Alpha- beta-, gamma- and delta-tocopherol represent the vitamin E group. These fat-soluble vitamins are essential for human nutrition, especially the alpha-form, which is commonly called vitamin E. About 80% of the tocopherols of hempseed oil is the alpha form. The vitamin E content of hempseed is comparatively high. Antioxidants in hempseed oil are believed to stabilize the highly polyunsaturated oil, tending to keep it from going rancid. Sterols in the seeds probably serve the same function, and like the tocopherols are also desirable from a human health viewpoint.

Cannabinoids may offer significant “side benefits” beyond analgesia. These include anti-emetic effects, well established with THC, but additionally demonstrated for CBD (Pertwee 2005), the ability of THC and CBD to produce apoptosis in malignant cells and inhibit cancer-induced angiogenesis (Kogan 2005; Ligresti et al 2006), as well as the neuroprotective antioxidant properties of the two substances (Hampson et al 1998), and improvements in symptomatic insomnia (Russo et al 2007).
Both in Canada and the US, the most critical problem to be addressed for commercial exploitation of C. sativa is the possible unauthorized drug use of the plant. Indeed, the reason hemp cultivation was made illegal in North America was concern that the hemp crop was a drug menace. The drug potential is, for practical purposes, measured by the presence of THC. THC is the world’s most popular illicit chemical, and indeed the fourth most popular recreational drug, after caffeine, alcohol, and nicotine. “Industrial hemp” is a phrase that has become common to designate hemp used for commercial non-intoxicant purposes. Small and Cronquist (1976) split C. sativa into two subspecies: C. sativa subsp. sativa, with less than 0.3% (dry weight) of THC in the upper (reproductive) part of the plant, and C. sativa subsp. indica (Lam.) E. Small & Cronq. with more than 0.3% THC. This classification has since been adopted in the European Community, Canada, and parts of Australia as a dividing line between cultivars that can be legally cultivated under license and forms that are considered to have too high a drug potential. For a period, 0.3% was also the allowable THC content limit for cultivation of hemp in the Soviet Union. In the US, Drug Enforcement Agency guidelines issued Dec. 7, 1999 expressly allowed products with a THC content of less than 0.3% to enter the US without a license; but subsequently permissible levels have been a source of continuing contention. Marijuana in the illicit market typically has a THC content of 5% to 10% (levels as high as 25% have been reported), and as a point of interest, a current Canadian government experimental medicinal marijuana production contract calls for the production of 6% marijuana. As noted above, a level of about 1% THC is considered the threshold for marijuana to have intoxicating potential, so the 0.3% level is conservative, and some countries (e.g. parts of Australia, Switzerland) have permitted the cultivation of cultivars with higher levels. It should be appreciated that there is considerable variation in THC content in different parts of the plant. THC content increases in the following order: achenes (excluding bracts), roots, large stems, smaller stems, older and larger leaves, younger and smaller leaves, flowers, perigonal bracts covering both the female flowers and fruits. It is well known in the illicit trade how to screen off the more potent fractions of the plant in order to increase THC levels in resultant drug products. Nevertheless, a level of 0.3% THC in the flowering parts of the plant is reflective of material that is too low in intoxicant potential to actually be used practically for illicit production of marijuana or other types of cannabis drugs. Below, the problem of permissible levels of THC in food products made from hempseed is discussed.
Cannabis plants produce a unique family of terpeno-phenolic compounds called cannabinoids, some of which produce the "high" which may be experienced from consuming marijuana. There are 483 identifiable chemical constituents known to exist in the cannabis plant, and at least 85 different cannabinoids have been isolated from the plant. The two cannabinoids usually produced in greatest abundance are cannabidiol (CBD) and/or Δ9-tetrahydrocannabinol (THC), but only THC is psychoactive. Since the early 1970s, Cannabis plants have been categorized by their chemical phenotype or "chemotype", based on the overall amount of THC produced, and on the ratio of THC to CBD. Although overall cannabinoid production is influenced by environmental factors, the THC/CBD ratio is genetically determined and remains fixed throughout the life of a plant. Non-drug plants produce relatively low levels of THC and high levels of CBD, while drug plants produce high levels of THC and low levels of CBD. When plants of these two chemotypes cross-pollinate, the plants in the first filial (F1) generation have an intermediate chemotype and produce intermedite amounts of CBD and THC. Female plants of this chemotype may produce enough THC to be utilized for drug production.
Hemp has been grown for millennia in Asia and the Middle East for its fibre. Commercial production of hemp in the West took off in the eighteenth century, but was grown in the sixteenth century in eastern England. Because of colonial and naval expansion of the era, economies needed large quantities of hemp for rope and oakum. In the early 1940s, world production of hemp fiber ranged from 250 000 to 350 000 metric tonnes, Russia was the biggest producer.
CBD Oil refers to CBD-infused products that contain CBD suspended in an oily base, such as vegetable glycerin, hempseed oil, or another plant-derived oil. Sublingual oils are ideal because they allow for rapid absorption of CBD through the membrane under your tongue directly into your bloodstream. CBD Oils are available in both low and high doses, and droppers built into the cap make it easy to measure your proper dose. CBD Oils are the most popular kind of CBD product thanks to their ease of use and rapid effects.
Hemp has at times in the past been grown simply for its ornamental value. The short, strongly-branched cultivar ‘Panorama’ (Fig. 43) bred by Iván Bósca, the dean of the world’s living hemp breeders, was commercialized in Hungary in the 1980s, and has been said to be the only ornamental hemp cultivar available. It has had limited success, of course, because there are very few circumstances that permit private gardeners can grow Cannabis as an ornamental today. By contrast, beautiful ornamental cultivars of opium poppy are widely cultivated in home gardens across North America, despite their absolute illegality and the potentially draconian penalties that could be imposed. Doubtless in the unlikely event that it became possible, many would grow hemp as an ornamental.
Hemp, or industrial hemp (from Old English hænep), typically found in the northern hemisphere, is a variety of the Cannabis sativa plant species that is grown specifically for the industrial uses of its derived products. It is one of the fastest growing plants and was one of the first plants to be spun into usable fiber 10,000 years ago. It can be refined into a variety of commercial items including paper, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed.
The overall effect is not assured because, like cannabis — which is illegal under U.S. federal law although some states have allowed medical or recreational use — states will continue to be able to enact laws related to industrial hemp, allowing for a potential patchwork of legislation across the country. Other questions remain in terms of how exactly the Agriculture Department will regulate the plant.
Protein. Hemp seeds contain 25%–30% protein, with a reasonably complete amino acid spectrum. About two thirds of hempseed protein is edestin. All eight amino acids essential in the human diet are present, as well as others. Although the protein content is smaller than that of soybean, it is much higher than in grains like wheat, rye, maize, oat, and barley. As noted above, the oilcake remaining after oil is expressed from the seeds is a very nutritious feed supplement for livestock, but it can also be used for production of a high-protein flour.
I am a former family doctor and naturopathic physician as well as a medical editor and author, working mostly in academic research. In my practice I have always focused on natural medicine and helped my patients of all ages who haven’t responded to traditional treatments. I also have written a significant number of articles in botanical medicine, addiction, drugs. As of now I'm focused on cannabis researches, especially on cannabidiol, its health benefits and how it can improve life of people with severe diseases. You can read my articles here on CBDreamers
We went back and forth like that for several rounds, yelling at each other in 30-degree weather in front of an RV wrapped in marijuana-leaf graphics and blasting Bob Marley music. Finally, he stopped trying to enlighten me and shuffled off to let me buy my lollies in peace. As I tore into my new treats, I realized the whole thing had been a scene from the internet’s dominant cannabidiol discourse come to life: Some money had been spent and some opinions had been said, but no one had gained any information.
“I just felt good,” he adds. “But I wasn’t high at all.” Joliat’s anecdotal experience with CBD is a common one. Some informal polling suggests a lot of people today are at least vaguely familiar with cannabidiol, and have either used it themselves or know someone who has. But even some people who use it don’t seem to know exactly what it is or whether there’s any hard science out there to back up its benefits.
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.
More recent studies have focused on the mechanisms behind the schizophrenia–cannabis interaction. Epstein and Kumra (2014) tested the effect of cannabis on executive control of attention and cognitive function by comparing scores on the Attention Network Test among people with early-onset schizophrenia (EOS) and cannabis use disorder, only EOS, only cannabis use disorder, and controls. They found that the first group in particular had less efficient executive control of attention compared with those who had only EOS. They also found a smaller right caudal anterior cingulate cortex in subjects with EOS and cannabis use disorder. However, it is presently unclear whether this means that the smaller cortex surface leads to deficits in self-regulation and heavy cannabis use or if the direction of causation is in the opposite direction. More recent studies have suggested gene–environment correlation between cannabis use and schizophrenia in that the increased risk of schizophrenia after heavy and consistent cannabis use may be moderated by a shared gene that may explain part of the association (Power et al., 2014).
A study by Henquet and colleagues (2004) substantially replicated both the Swedish and Dutch studies in a 4-year follow-up of a cohort of 2437 adolescents and young adults between 1995 and 1999 in Munich. They found a dose–response relationship between self-reported cannabis use at baseline and the likelihood of reporting psychotic symptoms. As in the Dutch cohort, young people who reported psychotic symptoms at baseline were much more likely to experience psychotic symptoms at follow-up if they used cannabis than were cannabis-using peers without such a history.
While CBD still faces legal hurdles to go mainstream, beverage giants, food companies and others have begun to take serious interest in the roughly $2 billion U.S. market. Tilray Inc. TLRY, +0.68% announced a partnership with Anheuser-Busch InBev SA BUD, -1.34% this week to research marijuana-based beverages, and Constellation Brands Inc. STZ, -0.03% has invested heavily in pot producer Canopy Growth Corp. Other large companies, like Molson Coors Brewing Co. TAP, -0.17% , have invested in research, and Coca-Cola Co. KO, -0.26% and others have at least considered making a play for the space.
Hearst and Rockefeller did not want Hemp or any form of Cannabis interfering with their lucrative paper, pharmaceutical and oil industries. Hemp is versatile and renewable. It can be used for food, medicine, fuel, paper, clothing, plastic, building materials; just about anything paper and oil is used for. These bastard wealthy people have done a disservice to all people and for the sake of lining their already copiously rich pockets. They and those like them are criminals of the worst order
Although the environmental and biodiversity benefits of growing hemp have been greatly exaggerated in the popular press, C. sativa is nevertheless exceptionally suitable for organic agriculture, and is remarkably less “ecotoxic” in comparison to most other crops (Montford and Small 1999b). Figure 50 presents a comparison of the ecological friendliness of Cannabis crops (fiber, oilseed, and narcotics) and 21 of the world’s major crops, based on 26 criteria used by Montford and Small (1999a) to compare the ecological friendliness of crops.
• Speaking of which: Has it been third-party tested? Nearly every expert Health spoke to agreed that your CBD products should be tested by a third party to confirm the label's accuracy. This is a real concern in the industry—take the 2017 Journal of the American Medical Association study, for example, which tested 84 CBD products and found that 26% contained lower doses than stated on the bottle. Look for a quality assurance stamp or certificate of analysis from a third party (aka not the actual brand) or check the retailer's website if you don't see it on the product's label.
Cannabis consumers have long prized potency (a high THC content) as one of the main factors that makes a particular strain more desirable. Though traditional demand for THC has caused an oversaturation of high-potency products, many consumers are starting to prefer less intense products that are lower in THC and higher in the non-intoxicating compound called cannabidiol (CBD).
I wanted to tell people here that CBD has been very effective for my anxiety, and helps with insomnia. For me, it was a cumulative effect, after a week of one dropper of oil, I can sleep very well at night. I feel like I am not polluting my body with commercial pharmaceuticals. I wish everyone here the best, and hope it works for you as well as it has for me.
Overall, Sativex appears to pose less risk of dependency than smoked cannabis based on its slower onset, lower dosage utilized in therapy, almost total absence of intoxication in regular usage, and minimal withdrawal symptomatology even after chronic administration. No known abuse or diversion incidents have been reported with Sativex to date (as of November 2007). Sativex is expected to be placed in Schedule IV of the Misuse of Drugs Act in the United Kingdom once approved.
Nabiximols (brand name Sativex) is a patented medicine containing CBD and THC in equal proportions. The drug was approved by Health Canada in 2005 for prescription to treat central neuropathic pain in multiple sclerosis, and in 2007 for cancer related pain. In New Zealand Sativex® is approved for use as an add-on treatment for symptom improvement in patients with moderate to severe spasticity due to Multiple Sclerosis who have not responded adequately to other anti-spasticity medication and who demonstrate clinically significant improvement in spasticity related symptoms during an initial trial of therapy.
Mainly what they look for in drug test is THC. Hemp contains only very minuscule amounts of THC. You cannot get high off of hemp. It is impossible. You would have to smoke or eat a boat load of hemp to even remotely get a buzz. A person could not ingest that much hemp, and a person would die of smoke inhalation before smoking enough to achieve a buzz. So hemp does not contain enough THC to show up on a drug screening. I hope this information helps you.
"Probably indigenous to temperate Asia, C. sativa is the most widely cited example of a “camp follower.” It was pre-adapted to thrive in the manured soils around man’s early settlements, which quickly led to its domestication (Schultes 1970). Hemp was harvested by the Chinese 8500 years ago (Schultes and Hofmann 1980). For most of its history, C. sativa was most valued as a fiber source, considerably less so as an intoxicant, and only to a limited extent as an oilseed crop. Hemp is one of the oldest sources of textile fiber, with extant remains of hempen cloth trailing back 6 millennia. Hemp grown for fiber was introduced to western Asia and Egypt, and subsequently to Europe somewhere between 1000 and 2000 BCE. Cultivation in Europe became widespread after 500 CE. The crop was first brought to South America in 1545, in Chile, and to North America in Port Royal, Acadia in 1606. The hemp industry flourished in Kentucky, Missouri, and Illinois between 1840 and 1860 because of the strong demand for sailcloth and cordage (Ehrensing 1998). From the end of the Civil War until 1912, virtually all hemp in the US was produced in Kentucky."
Cannabis impairs psychomotor performance in a wide variety of tasks, such as motor coordination, divided attention, and operative tasks of many types; human performance on complex machinery can be impaired for as long as 24 hours after smoking as little as 20 mg of THC in cannabis; there is an increased risk of motor vehicle accidents among persons who drive when intoxicated by cannabis.
This article reviews recent research on cannabinoid analgesia via the endocannabinoid system and non-receptor mechanisms, as well as randomized clinical trials employing cannabinoids in pain treatment. Tetrahydrocannabinol (THC, Marinol®) and nabilone (Cesamet®) are currently approved in the United States and other countries, but not for pain indications. Other synthetic cannabinoids, such as ajulemic acid, are in development. Crude herbal cannabis remains illegal in most jurisdictions but is also under investigation. Sativex®, a cannabis derived oromucosal spray containing equal proportions of THC (partial CB1 receptor agonist ) and cannabidiol (CBD, a non-euphoriant, anti-inflammatory analgesic with CB1 receptor antagonist and endocannabinoid modulating effects) was approved in Canada in 2005 for treatment of central neuropathic pain in multiple sclerosis, and in 2007 for intractable cancer pain. Numerous randomized clinical trials have demonstrated safety and efficacy for Sativex in central and peripheral neuropathic pain, rheumatoid arthritis and cancer pain. An Investigational New Drug application to conduct advanced clinical trials for cancer pain was approved by the US FDA in January 2006. Cannabinoid analgesics have generally been well tolerated in clinical trials with acceptable adverse event profiles. Their adjunctive addition to the pharmacological armamentarium for treatment of pain shows great promise.
