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.

First, a little background. Industrial hemp was legal in the United States until Congress passed the Marihuana Tax Act in 1937. ("Some of our early presidents grew hemp," notes Sarah Lee Gossett Parrish, a cannabis industry attorney based in Oklahoma.) Nearly 80 years later, the 2014 Farm Bill took the position that states can regulate the production of hemp and, as a result, CBD. Then last year, President Trump signed a new Farm Bill that made it federally legal to grow hemp.
Cannabis, (genus Cannabis), plant belonging to the family Cannabaceae of the nettle order (Urticales). By some classifications, the genus Cannabis comprises a single species, hemp (Cannabis sativa), a stout, aromatic, erect annual herb that originated in Central Asia and is now cultivated worldwide, including in Europe, southern Asia, the Middle East, India, Africa, and the Americas. A tall canelike variety is raised for the production of hemp fibre, while the female plant of a short branchier variety is prized as the more abundant source of the psychoactive substance tetrahydrocannabinol (THC), the active ingredient of marijuana.
In this edition of Cannabis Conversations, Project CBD Director, Martin A. Lee, discusses the benefits of CBD, the "entourage effect" and the microbiome with Dr. Ethan Russo. A neurologist, scientist, and widely published author, Dr. Russo is currently the director of research and development at the International Cannabis and Cannabinoids Institute in Prague (www.icci.science).
Known for invigorating and uplifting sensations, with a high focus in the mind rather than the body, sativas are extremely popular as daytime-use strains and for social occasions. Sativas are also widely associated with the cerebral and creativity-enhancing effects of weed. Hence, they are lauded by artists and other inventive people who use cannabis.
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.
It seems like everyone and her sister (and grandma, and aunt and second cousin twice-removed, and ... you get it) is sprinkling CBD oil in her smoothies because of claims it can help with everything from pain to anxiety. But what about CBD's sister: hemp oil? Are hemp oil benefits legit? Proponents say it can help with sleep and anxiety, balance your hormones, make your skin glow, and protect your ticker. But here's what you should know before you start drizzling it on top of your food or slathering it on your skin.
The phytocannabinoid cannabidiol (CBD), is a non-intoxicating molecule that results from the heating, or decarboxylation, of cannabidiolic acid, or CBDA. As popular as CBD has become in both the cannabis community and mainstream consumerism, its natural precursor, CBDA, is one of 114 unique cannabinoids found in cannabis. In most cultivars, or cultivated varieties of cannabis, CBD ranks low on the expression chart; there often isn’t much. However, following a explosive discovery in 2009 — it was noted that a handful of strains are rich in CBD over THC. Droves of CBD-rich cultivars began cropping up all across the US, resulting in a marked uptick in CBD availability across the states.
Lifestyle choices are contributing factors to poor health in many cases. These include smoking cigarettes, and can also include a poor diet, whether it is overeating or an overly constrictive diet. Inactivity can also contribute to health issues and also a lack of sleep, excessive alcohol consumption, and neglect of oral hygiene (Moffett2013).There are also genetic disorders that are inherited by the person and can vary in how much they affect the person and when they surface (Moffett, 2013).
While research into the effects of CBD on specific conditions is important, a broader perspective on the relationship between CBD and the human body is necessary to understand how this unique compound works. Interestingly, many of the conditions that are supposedly helped by CBD have no well-understood cause, from acne to Alzheimer’s disease. However, one of the few common denominators between these conditions is the involvement of the endocannabinoid system (ECS) in their causes.
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.
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.
There is certainly a need to utilize available germplasm sources in order to breed suitable cultivars for North America. A list of the 24 approved cultivars for the 2001 season in Canada is at www.hc-sc.gc.ca/hpb-dgps/therapeut/htmleng/hemp.html. Most of these are regulated by the European Organization of Economic Cooperation and Development (OECD). These cultivars are “approved” for use in Canada not on agricultural criteria, but merely on the basis that they meet the THC criterion. Indeed, most of these are unsuitable or only marginally suitable for Canada (Small and Marcus 2000), and only a very few Canadian cultivars to date have been created. In Canada, every acquisition of hemp grown at a particular place and time must be tested for THC content by an independent laboratory and, under the industrial hemp regulations, fields of hemp with more than 0.3% THC may require destruction (a slight degree of flexibility is generally exercised). Importation of experimental hemp lines (i.e. other than the approved cultivars) requires importation licenses (as well as phytosanitary clearance of the shipment by the Canadian Food Inspection Agency), and the importation licenses require an indication that the THC contents are low.
Yes, with some caveats. CBD and CBDa is legal in most states of the United States as long as it comes along with no more than 0.03% thc. CBD all by itself, is pretty much legal everywhere. However, you could still run into legal problems if you have a cop or court which is hell-bent on charging people with violation of marijuana laws or even laws about where you can buy non-psychoactive hemp. This is rare but has happened on occasion.
Cannabis is by far the most widely cultivated, trafficked and abused illicit drug. Half of all drug seizures worldwide are cannabis seizures. The geographical spread of those seizures is also global, covering practically every country of the world. About 147 million people, 2.5% of the world population, consume cannabis (annual prevalence) compared with 0.2% consuming cocaine and 0.2% consuming opiates. In the present decade, cannabis abuse has grown more rapidly than cocaine and opiate abuse. The most rapid growth in cannabis abuse since the 1960s has been in developed countries in North America, Western Europe and Australia. Cannabis has become more closely linked to youth culture and the age of initiation is usually lower than for other drugs. An analysis of cannabis markets shows that low prices coincide with high levels of abuse, and vice versa. Cannabis appears to be price-inelastic in the short term, but fairly elastic over the longer term. Though the number of cannabis consumers is greater than opiate and cocaine consumers, the lower prices of cannabis mean that, in economic terms, the cannabis market is much smaller than the opiate or cocaine market.
