For example, smoking pot is widely supposed to diminish the nausea associated with chemotherapy. But, the panel pointed out, “there are no good-quality randomized trials investigating this option.” We have evidence for marijuana as a treatment for pain, but “very little is known about the efficacy, dose, routes of administration, or side effects of commonly used and commercially available cannabis products in the United States.” The caveats continue. Is it good for epilepsy? “Insufficient evidence.” Tourette’s syndrome? Limited evidence. A.L.S., Huntington’s, and Parkinson’s? Insufficient evidence. Irritable-bowel syndrome? Insufficient evidence. Dementia and glaucoma? Probably not. Anxiety? Maybe. Depression? Probably not.
A mixture of fiberglass, hemp fiber, kenaf, and flax has been used since 2002 to make composite panels for automobiles.[37] The choice of which bast fiber to use is primarily based on cost and availability. Various car makers are beginning to use hemp in their cars, including Audi, BMW, Ford, GM, Chrysler, Honda, Iveco, Lotus, Mercedes, Mitsubishi, Porsche, Saturn, Volkswagen[38] and Volvo. For example, the Lotus Eco Elise[39] and the Mercedes C-Class both contain hemp (up to 20 kg in each car in the case of the latter).[40]
If you live in a state where CBD is legal for your condition, it’s best to buy it from a state-regulated dispensary. But even there, oversight is uneven. “I feel safe being a cannabis consumer in Colorado, since the state tracks everything from seed to sale, but I didn’t the first few years after cannabis became legal,” when the rules were still taking shape, says Robyn Griggs Lawrence, the Boulder author of The Cannabis Kitchen Cookbook, which features recipes for cannabis edibles.
Way back when, an angry and lobby-influenced Congress passed the Marihuana Tax Act of 1937, which effectively outlawed the possession of cannabis—including hemp—after hundreds of years of growth and use from the time of British colonization onward. While that law was repealed in the late 1960s, cannabis was quickly included as a Schedule 1 drug (the most “dangerous” class of drugs including heroin) in the Controlled Substances Act, a designation which continues to this day.
In this report, researchers reviewed 16 previously published studies testing the use of various cannabis-based medicines in the treatment of chronic neuropathic pain and found some evidence that cannabis-based medicines may help with pain relief and reduce pain intensity, sleep difficulties, and psychological distress. Side effects included sleepiness, dizziness, mental confusion. The authors concluded that the potential harm of such medicines may outweigh their possible benefit, however, it should be noted that the studies used a variety of cannabis-based medicines (e.g. inhaled cannabis and sprays and oral tablets containing THC and/or CBD from plant sources or made synthetically), some of which are more likely to result in these side effects than products without THC.
Zammit and colleagues’ findings were supported in a 3-year longitudinal study of the relationship between self-reported cannabis use and psychosis in a community sample of 4848 people in the Netherlands (van Os et al., 2002). Van Os and colleagues reported that cannabis use at baseline predicted an increased risk of psychotic symptoms during the follow-up period in individuals who had not reported psychiatric symptoms at baseline. There was a dose–response relationship between frequency of cannabis use at baseline and risk of psychotic symptoms during the follow-up period. These relationships persisted when they statistically controlled for the effects of other drug use. The relationship between cannabis use and psychotic symptoms was also stronger for cases with more severe psychotic symptoms.

Cannabis has mental and physical effects, such as creating a "high" or "stoned" feeling, a general change in perception, heightened mood, and an increase in appetite.[21][22] Onset of effects is within minutes when smoked, and about 30 to 60 minutes when cooked and eaten.[21][23] They last for between two and six hours.[23] Short-term side effects may include a decrease in short-term memory, dry mouth, impaired motor skills, red eyes, and feelings of paranoia or anxiety.[21][24][25] Long-term side effects may include addiction, decreased mental ability in those who started as teenagers, and behavioral problems in children whose mothers used cannabis during pregnancy.[21] There is a strong relation between cannabis use and the risk of psychosis,[26] though the cause-and-effect is debated.[27]
Earlier this month, the world received more indicators that the “Green Rush,” once merely on the horizon, is advancing into view with increasing velocity. It really wasn’t long ago that most portrayals of legal cannabis consumers reflected long-held clichés, reinforcing a stereotype that only a certain subset of the populace used cannabis products.
"However, it is clear that, even prior to the 2018 Farm Bill, North Carolina was producing hemp flowers legally by licensed growers. The 2018 Farm Bill effectively moved oversight from the DEA to the U.S. Department of Agriculture for hemp and all its derivatives and extracts. At the same time, the law removed CBD that is produced by licensed growers of industrial hemp from the controlled substance list. The USDA has not developed its program yet – the Farm Bill was only signed in December 2018 – so we are still operating our NC Pilot program and licensing farmers under that."

"Hemp hurd is composed of cellulose-rich, short fibres, and make up approximately 75% of the hemp stalk. They are spongy and absorbent, ideal characteristics in applications such as animal bedding and industrial absorbents. They may also be used to produce low-quality paper. More recently, hemp hurd has been used to produce a concrete-like substance for use in building applications, as well as for insulation and to produce fibreboard."
This guide is an introduction to anyone looking to inform themselves about the reality of cannabis. It covers basic information about the marijuana plant, cannabis preparations, and the crucial elements of plant anatomy and science. This guide to marijuana also gives an overview of the most popular medical and recreational uses of cannabis. It offers a survey of the most important medical cannabis research while highlighting emerging trends in the legal cannabis market. The guide also introduces those new to cannabis to the many ways to consume marijuana, and much more.
James Joliat, a 35-year-old video producer in Denver, has long experienced muscle and joint pain—mostly related to sports injuries. He says he started looking at natural remedies as an alternative to the prescription patches and pills his doctor recommended. After experimenting with homemade rubs infused with plant compounds—stuff like arnica and turmeric—he eventually stumbled onto topical cannabidiol (CBD) rubs.
The endocannabinoid system is tonically active in control of pain, as demonstrated by the ability of SR141716A (rimonabant), a CB1 antagonist, to produce hyperalgesia upon administration to mice (Richardson et al 1997). As mentioned above, the ECS is active throughout the neuraxis, including integrative functions in the periacqueductal gray (Walker et al 1999a; Walker et al 1999b), and in the ventroposterolateral nucleus of the thalamus, in which cannabinoids proved to be 10-fold more potent than morphine in wide dynamic range neurons mediating pain (Martin et al 1996). The ECS also mediates central stress-induced analgesia (Hohmann et al 2005), and is active in nociceptive spinal areas (Hohmann et al 1995; Richardson et al 1998a) including mechanisms of wind-up (Strangman and Walker 1999) and N-methyl-D-aspartate (NMDA) receptors (Richardson et al 1998b). It was recently demonstrated that cannabinoid agonists suppress the maintenance of vincristine-induced allodynia through activation of CB1 and CB2 receptors in the spinal cord (Rahn et al 2007). The ECS is also active peripherally (Richardson et al 1998c) where CB1 stimulation reduces pain, inflammation and hyperalgesia. These mechanisms were also proven to include mediation of contact dermatitis via CB1 and CB2 with benefits of THC noted systemically and locally on inflammation and itch (Karsak et al 2007). Recent experiments in mice have even suggested the paramount importance of peripheral over central CB1 receptors in nociception of pain (Agarwal et al 2007)
Hemp was made illegal to grow without a permit in the U.S. under the Controlled Substances Act passed in 1970 because of its relation to marijuana,[18] and any imported hemp products must meet a zero tolerance level.[92] Some states have made the cultivation of industrial hemp legal, but farmers in many states have not yet begun to grow it because of resistance from the federal Drug Enforcement Administration,[93] making "large-scale hemp growing" in the United States "not viable" as late as 2013.[94] In 2013, after the legalization of cannabis in the state, several farmers in Colorado planted and harvested several acres of hemp, bringing in the first hemp crop in the United States in over half a century.[95] Colorado,[96] Vermont, California, and North Dakota have passed laws enabling hemp licensure. All four states are waiting for permission to grow hemp from the DEA. Currently,[97] Oregon has licensed industrial hemp as of August 2009.[98] Congress included a provision in the Agricultural Act of 2014 that allowed colleges and state agencies to grow and conduct research on hemp in states where it is legal.[18] Hemp production in Kentucky, formerly the United States' leading producer, resumed in 2014.[99] Hemp production in North Carolina resumed in 2017,[100] and in Washington State the same year.[101] By the end of 2017, at least 34 U.S. states had industrial hemp programs.[102] In 2018, New York began taking strides in industrial hemp production, along with hemp research pilot programs at Cornell University, Binghamton University and SUNY Morrisville.[103]
Moreover, a patient survey conducted by Project CBD, declared that “…cannabis appears to be an effective pain management tool with few negative side effects.” The study went on to say that a “…significant decrease in opiate usage among elderly patients while taking medical cannabis [was observed during trial].” In short, it has been portrayed clearly numerous times through valid and well-publicized clinical studies that cannabis is a practical option in terms of efficient pain management.
In a study with HIV-positive adult men, blood concentrations of ghrelin and other appetitive hormones (leptin, PYY, and insulin) were tested after having received smoked medicinal cannabis or matched placebo for HIV-associated neuropathic pain. Cannabis administration, as compared to placebo, significantly increased ghrelin concentrations in this study. In addition, leptin and PYY levels were, respectively, increased and decreased, but no impact on insulin levels was found (Riggs et al., 2012).
Hemp was a prominent crop in the United States until 1937, when the Marihuana Tax Act virtually obliterated the American hemp industry. During World War II, hemp saw a resurgence in the U.S., as it was used extensively to make military items ranging from uniforms to canvas and rope. The United States Department of Agriculture even released a short documentary, “Hemp for Victory,” in 1942, which promoted hemp as a useful crop for the war cause.
Only a handful of countries have legalized recreational marijuana. Uruguay was one of the first, in 2013. The Netherlands is perhaps the country most known for legal marijuana, yet the drug is illegal there. Spain has given its citizens the rights to grow and consume cannabis privately. Peru also allows citizens to possess marijuana as long as it is for personal, private use. As in Costa Rica, where people can have a “small amount,” without legal trouble.
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.

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.

The use of Cannabis as a mind-altering drug has been documented by archaeological finds in prehistoric societies in Eurasia and Africa.[85] The oldest written record of cannabis usage is the Greek historian Herodotus's reference to the central Eurasian Scythians taking cannabis steam baths.[86] His (c. 440 BCE) Histories records, "The Scythians, as I said, take some of this hemp-seed [presumably, flowers], and, creeping under the felt coverings, throw it upon the red-hot stones; immediately it smokes, and gives out such a vapour as no Grecian vapour-bath can exceed; the Scyths, delighted, shout for joy."[87] Classical Greeks and Romans were using cannabis, while in the Middle East, use spread throughout the Islamic empire to North Africa. In 1545, cannabis spread to the western hemisphere where Spaniards imported it to Chile for its use as fiber. In North America, cannabis, in the form of hemp, was grown for use in rope, clothing and paper.[88][89][90][91]
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.

Various car makers are beginning to use hemp in their cars, including Audi, BMW, Ford, GM, Chrysler, Honda, Iveco, Lotus, Mercedes, Mitsubishi, Porsche, Saturn, Volkswagen[38] and Volvo. For example, the Lotus Eco Elise[39] and the Mercedes C-Class both contain hemp (up to 20 kg in each car in the case of the latter).[40]

CBD directly interacts with a number of proteins in the body and central nervous system, a few of which are components of the endogenous cannabinoid system. For instance, CBD binds to both the CB1 and CB2 cannabinoid receptors, but it binds in a way that sets off a reaction that is essentially the opposite of what THC does. CBD is an inverse agonist, while THC is an agonist at CB1. Simply put, CBD is not intoxicating; at the molecular level, it does the opposite of what THC does. Our bodies have several other receptor proteins that participate in the endogenous cannabinoid system (GPR3, GPR6, TRPV1 and TRPV2, for example). CBD binds to all of these, and many of its anti-inflammatory and pain-relieving effects may occur through these pathways.


Cannabis is indigenous to Central Asia[192] and the Indian subcontinent,[193] and its use for fabric and rope dates back to the Neolithic age in China and Japan.[194][195] It is unclear when cannabis first became known for its psychoactive properties; some scholars suggest that the ancient Indian drug soma, mentioned in the Vedas, was cannabis, although this theory is disputed.[196]
In the meantime, some physicians are forging ahead — and cashing in. Joe Cohen is a doctor at Holos Health, a medical marijuana clinic in Boulder. I asked him what CBD is good for, and he read me a long list of conditions: pain, inflammation, nausea, vomiting, intestinal cramping, anxiety, psychosis, muscle spasms, hyperactive immune systems, nervous system degeneration, elevated blood sugar and more. He also claimed that CBD has anti-cancer properties and can regenerate brain cells and reduce the brain’s levels of amyloid beta — a kind of protein that’s been linked to Alzheimer’s disease. I asked for references, noting that most of these weren’t listed in the Academies report or a similar review published in the Journal of the American Medical Association. “I think you just have to Google search it,” he said. It’s true that a preliminary study found hints that cannabinoids might reduce beta amyloid proteins in human brain cells, but the study was done in cells grown in a lab, not in people. As for cancer, the FDA sent warning letters last year to four companies that were selling products that claimed to “prevent, diagnose, treat or cure” cancer.

Ajulemic acid (CT3, IP-751) (Figure 1), another synthetic dimethylheptyl analogue, was employed in a Phase II RCT in 21 subjects with improvement in peripheral neuropathic pain (Karst et al 2003) (Table 1). Part of its analgesic activity may relate to binding to intracellular peroxisome proliferator-activator receptor gamma (Liu et al 2003). Peak plasma concentrations have generally been attained in 1–2 hours, but with delays up to 4–5 hours is some subjects (Karst et al 2003). Debate surrounds the degree of psychoactivity associated with the drug (Dyson et al 2005). Current research is confined to the indication of interstitial cystitis.


“It probably should be called snake oil,” says Tishler. (So...save your cash.) Not only does hemp oil not have any real health benefits, but it may contain stuff that's actually bad for you. "At the moment what you can buy is less regulated than the potato at the supermarket," says Tishler. When hemp oil is extracted, there's a risk that pesticides, plastics, and heavy metals could make their way in, says Tishler.
There are multiple ways to take CBD oil. How you use CBD oil depends on your personal preferences and your specific needs. For example, if you are suffering from joint or muscle pain, using a topical cream may be the most effective format. But you can also take it in capsule form, vape, smokables, transdermal patches, edibles, and drops. You can take it with THC (which may actually boost the anti-inflammatory benefits) or without.

Several studies have demonstrated the therapeutic effects of cannabinoids for nausea and vomiting in the advanced stages of illnesses such as cancer and AIDS. Dronabinol (tetrahydrocannabinol) has been available by prescription for more than a decade in the USA. Other therapeutic uses of cannabinoids are being demonstrated by controlled studies, including treatment of asthma and glaucoma, as an antidepressant, appetite stimulant, anticonvulsant and anti-spasmodic, research in this area should continue. For example, more basic research on the central and peripheral mechanisms of the effects of cannabinoids on gastrointestinal function may improve the ability to alleviate nausea and emesis. More research is needed on the basic neuropharmacology of THC and other cannabinoids so that better therapeutic agents can be found.

Hemp CBD oil is not regulated, creating a situation of buyer beware. Despite this, hemp CBD oil continues to be in high demand as a growing number of chronic pain patients look for alternatives to opioids and drugs with troubling side effects. With so many companies pushing their products, how can you ensure you’re purchasing a quality product that’s potent and safe to use?
The tricky part is that there's some evidence suggesting CBD works best for pain when combined with a little THC, says Dr. Danesh. "Depending on what type of pain you have, you might be able to do just CBD, but sometimes you need CBD and THC." This makes accessing a product that will actually help you more difficult due to different regulations in each state. In New York, where Dr. Danesh practices, for example, CBD is available over the counter. But as soon as you add THC, you need a prescription.
The key is to effectively gauge exactly how much CBD oil it takes to start managing your pain. If you start off right away with a maximum dose of a 600 mg tincture, you will have no idea how much of the product it actually took to treat your condition, and how much you wasted (this is also important because you do not want to exceed dosage and end up developing a tolerance to the active cannabinoids).
CBD is a 5-HT1A receptor agonist, which may also contribute to an anxiolytic effect.[156] This likely means the high concentrations of CBD found in Cannabis indica mitigate the anxiogenic effect of THC significantly.[156] The cannabis industry claims that sativa strains provide a more stimulating psychoactive high while indica strains are more sedating with a body high.[157] However this is disputed by researchers.[158]

Hashish (also spelled hasheesh, hashisha, or simply hash) is a concentrated resin cake or ball produced from pressed kief, the detached trichomes and fine material that falls off cannabis flowers and leaves.[179] or from scraping the resin from the surface of the plants and rolling it into balls. It varies in color from black to golden brown depending upon purity and variety of cultivar it was obtained from.[180] It can be consumed orally or smoked, and is also vaporised, or 'vaped'.[181] The term "rosin hash" refers to a high quality solventless product obtained through heat and pressure.[182]

Yet even those who believe in this power recognize that CBD medicine remains largely unexplored: Treatments are not systematized, many products are not standardized or tested, and patients (or their parents) are generally left to figure out dosing on their own. While some suppliers and dispensaries test the CBD and THC levels of their products, many do not. “We really need more research, and more evidence,” Kogan says. “This has to be done scientifically.”
Studies at Bejing's Hemp Research Center revealed the variety of plant uses, prompting China to expand its hemp production which is a mere fraction of its world-leading cotton production. China not only has the product, but they have the cultivation techniques and commercial technologies to capitalize on that supply. And they are ramping up to leverage their competitive hemp advantage, expecting an eager demand from U.S. manufacturers given hemp's rise in popular applications. 

An absence of such fiber-strain traits as tallness, limited branching, long internodes, and very hollow stems, is characteristic of narcotic strains. Drug forms have historically been grown in areas south of the north-temperate zone, often close to the equator, and are photoperiodically adapted to a long season. When grown in north-temperate climates maturation is much-delayed until late fall, or the plants succumb to cold weather before they are able to produce seeds. Unlike fiber strains that have been selected to grow well at extremely high densities, drug strains tend to be less persistent when grown in high concentration (de Meijer 1994). Drug strains can be very similar in appearance to fiber strains. However, a characteristic type of narcotic plant was selected in southern Asia, particularly in India and neighboring countries. This is dioecious, short (about a meter in height), highly branched, with large leaves (i.e. wide leaflets), and it is slow to mature. The appearance is rather like a short, conical Christmas tree.
Although CBD oils aren’t regulated by the FDA, purchasing products stateside from one of the nine states where recreational and medical cannabis use is legal will likely result in a higher-quality product than buying one made with hemp-derived CBD oil imported from abroad, says Martin Lee, director of Project CBD, a nonprofit that promotes medical research into CBD.
Hemp is not the same as marijuana. One really has nothing to do with the other. Hemp was made illegal back in the days when cotton was king in the south and southern cotton plantation owners did not want the competition. They lobbied for, and got a law against hemp being grown nationwide. It never had to do with drugs at that time, and still doesn’t. As always, money and government go hand in hand. Now, recently, South Carolina has legalized growing hemp again, which is the only state in 50 to do so. We will hope for more enlightened agri-business legislation across the nation, soon.

"Production differences depend on whether the cannabis plant is grown for fiber/oilseed or for medicinal/recreational uses. These differences involve the varieties being grown, the methods used to grow them, and the timing of their harvest (see discussion in 'Hemp' and 'Marijuana,' below). Concerns about cross-pollination among the different varieties are critical. All cannabis plants are open, wind and/or insect pollinated, and thus cross-pollination is possible.
Cannabis use and psychotic symptoms and disorders are associated in the general population (see, for example, Degenhardt and Hall, 2001; Tien and Anthony, 1990) and in clinical samples of patients with schizophrenia (Mueser et al., 1992; Warner et al., 1994; Hambrecht and Hafner, 1996). The major contending hypotheses to explain the association have been: (i) that cannabis use precipitates schizophrenia in persons who are otherwise vulnerable; (ii) cannabis use is a form of self-medication for schizophrenia; and (iii) that the association arises from uncontrolled residual confounding by variables that predict an increased risk of cannabis use and of schizophrenia (Macleod et al., 2004).
The clinical trials performed with Sativex have recently been assessed in two independent review articles (Barnes 2006; Pérez 2006). In a Phase II clinical trial in 20 patients with neurogenic symptoms (Wade et al 2003), Tetranabinex, Nabidiolex, and Sativex were tested in a double-blind RCT vs placebo (Table 1). Significant improvement was seen with both Tetranabinex and Sativex on pain (especially neuropathic), but post-hoc analysis showed symptom control was best with Sativex (p < 0.0001), with less intoxication than with THC-predominant extract.
All that's changed with the high trade tariffs Trump's levied on countries who import our products. Analysts and existing evidence suggest the soybean trade conflicts will be in favor of fellow exporters, Brazil and Argentina, rather than the U.S. The tariff could drop China’s imports of soybeans by 69% on average. The estimated effect of China’s 25% tariff on U.S. soybean imports would cut income for a midsize Illinois grain farm by an average of 87% over four years, prompting a loss of more than $500,000 in the farm’s net worth by 2021.
CBD concentrates typically contain the strongest dosage of CBD compared to any other CBD products. It can contain up to 10 times the average CBD products. Concentrates are also convenient in that it only takes a few seconds to consume. Overall, CBD concentrates seem to be most popular among customers who are extremely busy, yet seek high potency CBD.
Cannabidiol is insoluble in water but soluble in organic solvents such as pentane. At room temperature, it is a colorless crystalline solid.[42] In strongly basic media and the presence of air, it is oxidized to a quinone.[43] Under acidic conditions it cyclizes to THC,[44] which also occurs during pyrolysis (smoking).[45] The synthesis of cannabidiol has been accomplished by several research groups.[46][47][48]
What exactly is cannabidiol (CBD) and more importantly, what does it do? Those questions and more are at the heart of this comprehensive guide to one of the most fascinating and important compounds of the cannabis plant. Cannabis plants are chemical powerhouses that produce more than 400 different compounds. Not all of those compounds are unique to marijuana, of course, and appear in many other species of plants. That’s why marijuana can smell like pine trees or taste like fresh lemons. But of those 400 compounds, more than 60 of them are totally specific to the plant genus Cannabis. Scientists call these special compounds “cannabinoids.” However, not all cannabinoids are created equal. One of them, cannabidiol, or CBD, holds the key to the wide variety of medicinal and therapeutic effects marijuana offers.

Cannabis has psychoactive and physiological effects when consumed.[45] 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[46] 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[47][48] and derealization.[49]
Researchers in New Zealand have studied whether cannabis can be used to treat severe motor and vocal tics in those suffering from Tourette syndrome. The study concluded that subjects who took a controlled THC-CBD medicated spray showed marked improvement in the frequency and severity of motor and vocal tics post-treatment. Although the study is only a small clinical trial, it is one of the first to specifically analyze the effects of cannabis on Tourette syndrome.
