According to DSM-V criteria, 9% of those who are exposed to cannabis develop cannabis use disorder, compared to 20% for cocaine, 23% for alcohol and 68% for nicotine. Cannabis abuse disorder in the DSM-V involves a combination of DSM-IV criteria for cannabis abuse and dependence, plus the addition of craving, minus the criterion related to legal troubles.
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).

“Industrial hemp, along with all strains of cannabis, are decades behind other agricultural crops in terms of improved plant genetics,” said Arcadia Chief Financial Officer Matt Plavan. “With the explosive market growth projected in the industrial hemp and derivative markets, growers will need the very best hemp strains to meet demand, minimize waste, and ensure consistent quality.”
Administer a few small doses over the course of the day rather than one big dose. Use the same dose and ratio for several days. Observe the effects and if necessary adjust the ratio or amount. Don’t overdo it. Cannabis compounds have ‘biphasic properties’, which means that low and high doses of the same substance can produce opposite effects. Small doses of cannabis tend to stimulate; large doses sedate.
Cannabis is frequently used among Sufis – the mystical interpretation of Islam that exerts strong influence over local Muslim practices in Bangladesh, India, Indonesia, Turkey, and Pakistan. Cannabis preparations are frequently used at Sufi festivals in those countries. Pakistan's Shrine of Lal Shahbaz Qalandar in Sindh province is particularly renowned for the widespread use of cannabis at the shrine's celebrations, especially its annual Urs festival and Thursday evening dhamaal sessions - or meditative dancing sessions.
^ A 2016 review also found a statistically significant increase in crash risk associated with marijuana use, but noted that this risk was "of low to medium magnitude." The increase in risk of motor vehicle crash for cannabis use is between 2 and 3 times relative to baseline, whereas that for comparable doses of alcohol is between 6 and 15 times.

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).
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.
Great quality, easy to find at nearby shop. I love the almost instant relief it brings. Was skeptical at first, never liked a tingly or cooling sensation from certain essential oils but this product is hands down the best and ill handle the icy sensation any day! Use it on my neck, back and knees, thank you for making a great accessible alternative for people!
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.
All CBD products start out the same way: as an extract from the leaves and flowers of cannabis plants. At Green Roads, we only extract CBD from hemp, defined as any variety of cannabis plant containing less than 0.3% THC by dry weight. Cannabinoids and terpenes are produced by tiny glands on the leaves and flowers of cannabis plants known as trichomes. The compounds produced by these trichomes give cannabis both its rich aroma and its nutraceutical effects.
Another concern is about medications with which CBD might interact. This won’t be an issue with most drugs, says Sunil Kumar Aggarwal, M.D., Ph.D., a palliative medicine physician and scientist who studies cannabis and integrates it into his Seattle medical practice. The exceptions are blood thinners, IV antibiotics, and other drugs whose exact dosing is crucial and must be monitored closely, he says. (Of course, if you have a health problem, talk to your doctor before using CBD, and never take it instead of seeing your physician for a serious condition.)
The objectivity of scientific evaluation of the medicinal value of marijuana to date has been questioned. In the words of Hirst et al. (1998): “The ...status of cannabis has made modern clinical research almost impossible. This is primarily because of the legal, ethical and bureaucratic difficulties in conducting trials with patients. Additionally, the general attitude towards cannabis, in which it is seen only as a drug of abuse and addiction, has not helped.” In a recent editorial, the respected journal Nature (2001) stated: “Governments, including the US federal government, have until recently refused to sanction the medical use of marijuana, and have also done what they can to prevent its clinical testing. They have defended their inaction by claiming that either step would signal to the public a softening of the so-called ‘war on drugs.’... The pharmacology of cannabinoids is a valid field of scientific investigation. Pharmacologists have the tools and the methodologies to realize its considerable potential, provided the political climate permits them to do so.” Given these current demands for research on medicinal marijuana, it will be necessary to produce crops of drug types of C. sativa.
The reason researchers and cannabis companies are interested in alternative ways of producing cannabinoids is that working with the original plant is messy and complicated. First of all, growing the stuff takes a lot of time, water, and energy (if you’re cultivating indoors). Extracting certain cannabinoids from flower is also a hassle. If you’re only after CBD, for example, there’s a chance your extract could be contaminated with THC. This is of particular concern if you want to isolate CBD for use as a medicine—it’s been shown, for instance, to be remarkably effective in treating epilepsy.
Understanding CBD’s analgesic, or pain-relieving, interactions with the ECS can shed light on CBD’s other interactions and effects. Importantly, the ECS participates in our bodies’ pain processing, but when CBD is introduced to our ECS, it stops the body from absorbing a pain-regulating compound known as anandamide — one of our body’s’ own natural cannabinoid molecules. Inhibiting the absorption of this compound shunts excess quantities into the bloodstream that in turn reduces pain. One study has revealed that CBD targets alpha-3 (α3) glycine receptors to suppress chronic pain and inflammation associated with dysfunctional glycine receptors, which are an important target for pain processing in the spine. In both humans and animal models, CBD has been shown to have a variety of anti-inflammatory properties.
A colleague of Mechoulam’s, Marc Feldman at Imperial College, London, tested CBD on mice that had a version of rheumatoid arthritis. He found that CBD reduced the mice’s inflammation by 50% at the right dosage. Cardiologists working with the mice at Hebrew University have found that a dosage of CBD immediately following a heart attack can reduce infarct size by about 66%.
Because C. sativa has been a neglected crop for so long in North America, there are only negligible genetic resources available on this continent. Most germplasm stocks of hemp are in Europe, and the largest and most important collection is the Vavilov Institute gene bank in Leningrad. Figure 11 shows THC concentrations in the Vavilov collection, as well as in our own collection, largely of European germplasm. A disturbingly high percentage of the collections have THC levels higher than 0.3%, making it difficult to incorporate these into breeding programs.
There's no question that CBD is the buzzy wellness product of the moment. If you live in a state where it's currently legal, you might feel like CBD has gone from being sort of around to absolutely everywhere all at once. Coffee shops sell CBD lattes, spas offer CBD facials, beauty companies are rushing to release lotions with CBD or hemp oils in their formulas. And everyone from your anxious coworker to your arthritis-suffering dad wants to get their hands on some CBD gummies.
In 2017, the cultivated area for hemp in the Prairie provinces include Saskatchewan with more than 56,000 acres (23,000 ha), Alberta with 45,000 acres (18,000 ha), and Manitoba with 30,000 acres (12,000 ha). Canadian hemp is cultivated mostly for its food value as hulled hemp seeds, hemp oils and hemp protein powders, with only a small fraction devoted to production of hemp fiber used for construction and insulation.
Document It: Keep a journal of your dog before and for several days if you decide to use a CBD product. This will help you decide whether it’s having a positive effect. Better still, record video of your dog to document their progress, or lack thereof (this will help you overcome the flaws of human memory). Or ask your friends/family whether they’ve noticed any difference in your dog without telling them that you’ve been giving your dog CBD (the closest you’ll get to a blinded study).
In November 2015, Uttarakhand became the first state of India to legalize the cultivation of hemp for industrial purposes. Usage within the Hindu and Buddhist cultures of the Indian subcontinent is common, with many street vendors in India openly selling products infused with cannabis, and traditional medical practitioners in Sri Lanka selling products infused with cannabis for recreational purposes and well as for religious celebrations. It was criminalized in the Indian subcontinent by the Dutch and then the British. India and Sri Lanka have allowed cannabis to be taken in the context of traditional culture for recreational/celebratory purposes and also for medicinal purposes.

Dogs are considered man’s best friend and they have been seen being part of the majority of the families, that is why they already consider their pets like humans and have necessary needs like food, water, shelter, attention, and even vaccines to guard them against different types of diseases. As we all know, the lifespan of dogs are shorter than humans and as much as possible, we want to maximize their time by giving them necessary medications to keep them healthy and avoid getting sick. However, there are certain human diseases that can also be diagnosed to dogs such as heat stroke, lymphoma, anxiety, seizures and even cancer.
"Skunk" refers to several named strains of potent cannabis, grown through selective breeding and sometimes hydroponics. It is a cross-breed of Cannabis sativa and C. indica (although other strains of this mix exist in abundance). Skunk cannabis potency ranges usually from 6% to 15% and rarely as high as 20%. The average THC level in coffee shops in the Netherlands is about 18–19%.
The theoretical logic is there, Gerdeman says. What exactly is that thinking? Well, there are a few different ways CBD could help regulate pain—by increasing your natural endocannabinoids, decreasing your inflammatory response, and desensitizing your pain receptors (although it’s still unclear whether this stands when absorbed topically compared to orally).
• In 2016, Dr. Stephanie McGrath, neurologist and assistant professor at Colorado State University’s College of Veterinary Medicine & Biomedical Sciences, completed a preliminary pharmacokinetic (what happens to a drug in the body) and safety study on CBD. Following this study, Dr. McGrath began two pilot studies involving owner-enrolled dogs with poorly controlled epilepsy and painful osteoarthritis. These have now ended and results on the epilepsy study are scheduled for publication in the Canadian Veterinary Journal later this year. One of its big-picture findings: 89 percent of dogs who received CBD had a reduction in the frequency of seizures. (McGrath and her team are now starting work on a larger epilepsy-focused project.)
Hemp stalk is baled for transportation and long-term storage using traditional farming balers. Large round balers are best for hemp because they allow for more thorough drying as they don’t pack the hemp as tightly as square balers. Hemp should be stored in a dry environment in conditions intended to reduce as much absorbable air moisture as possible. It’s also important to check for wet patches during baling to further avoid mold.
For profitable hemp farming, particularly deep, humus-rich, nutrient-rich soil with controlled water flow is preferable. Waterlogged acidic, compressed or extremely light (sandy) soils primarily affect the early development of plants. Steep and high altitudes of more than 400 m above sea level are best avoided. Hemp is relatively insensitive to cold temperatures and can withstand frost down to −5 °C. Seeds can germinate down to 1–3 °C. Hemp needs a lot of heat, so earlier varieties come to maturation. The water requirement is 300–500 l/kg dry matter. This is around 1/14th that of cotton, which takes between 7,000 and 29,000 l/kg, according to WWF. Roots can grow up to 3 feet into the soil and use water from deeper soil layers.
While normally I'd be slightly tripped up by little things like an overly crowded subway car or a full inbox at work, the CBD oil seems to have taken the edge off of my anxiety a bit. Rather than overthinking a sternly worded email or analyzing a social interaction, I've found it easier to recognize the irrationality of these thoughts and actually let them go (instead of ruminating on the situation). In some ways, I feel more like myself. With that said, I've still experienced some social anxiety when meeting new groups of people—I'd be interested to see what taking the full recommended dose would do.
Quality is a particular concern, because cannabis plants easily soak up heavy metals from pesticides and other contaminants, Marcu says. If you are buying online, look for a company that documents how it tests its products. (If the website doesn’t indicate this, call and ask.) “Buying from a reputable manufacturer is crucial, because it matters how the plant is cultivated and processed,” Dr. Maroon says. One clue that a company is cutting corners: too low a cost. Good CBD is pricey—a bottle of high-quality capsules is sold in Cohen’s office for $140. But for many, it’s worth the money. Roth spent $60 on her tiny bottle. But when her energy returned the day she started taking CBD, she decided that was a small price to pay.
Aggressive behavior can be caused by many different factors including stress, anxiety, or an unfamiliar situation. Researchers believe that using CBD oil for dogs can help minimize your dog’s aggression behavior by combatting the root causes – stress and anxiety. By lowering stress and anxiety, CBD can make your dog feel more comfortable and can ultimately decrease your dog’s aggression.
If you haven’t been bombarded with CBD marketing or raves about it from friends, get ready. This extract—which comes from either marijuana or its industrial cousin, hemp—is popping up everywhere. There are CBD capsules, tinctures, and liquids for vaping plus CBD-infused lotions, beauty products, snacks, coffee, and even vaginal suppositories. Already some 1,000 brands of CBD products are available in stores—and online in states that don’t have lenient cannabis laws. This is a tiny fraction of what’s to come: The CBD market is poised to exceed $1 billion by 2020, per the Chicago-based research firm Brightfield Group.
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.
At an epidemiological level, a dose response relationship exists between cannabis use and increased risk of psychosis and earlier onset of psychosis. Although the epidemiological association is robust, evidence to prove a causal relationship is lacking. But a biological causal pathway is plausible, especially if there is a genetic predisposition to mental illness, in which case cannabis may be a trigger.[better source needed]
Hemp seeds contain virtually no THC, but THC contamination results from contact of the seeds with the resin secreted by the epidermal glands on the leaves and floral parts, and also by the failure to sift away all of the bracts (which have the highest concentration of THC of any parts of the plant) that cover the seeds. This results in small levels of THC appearing in hempseed oil and foods made with the seeds. Although most of the western hemp-growing world uses 0.3% THC as a maximum concentration for authorized cultivation of hemp plants, regulations in various countries allow only a much lower level of THC in human food products manufactured from the seeds. Currently, up to 10 ppm THC is permitted in seeds and oil products used for food purposes in Canada. In Germany, more stringent limits were set for food in 2000: 5 ppm in food oil, 0.005 ppm in beverages, and 0.15 ppm in all other foods. The US Drug Enforcement Administration published new regulations on hemp in the Federal Register on October 9th 2001 that in effect 4 months later would ban the food use of hemp in the US because any amount of THC would be unacceptable in foods (follow links at www.hempreport.com/). These proposals are currently being challenged by the hemp industry. Limits have been set because of concerns about possible toxicity and interference with drug tests (Grotenhermen et al. 1998). An extensive analysis of literature dealing with the toxicity of hemp is in Orr and Starodub (1999; see Geiwitz 2001 for an analysis). Because hemp food products are considered to have great economic potential, there is considerable pressure on the hemp industry in North America to reduce THC levels.
