"The survey covers the harvest of 2013, related to a total cultivation area of 15,700 ha. The first figure shows the development of the cultivation area since 1993. Between 1993 and 1996 the cultivation of industrial hemp was legalised in most of the member states, others followed later. In 2011 the cultivation area decreased to its lowest value since 1994 (ca. 8,000 ha), but increased in 2012, 2013 and 2014, to finally reach 25,000 ha in 2015. In 2016 a further increase is expected. The main cultivation member states are France and The Netherlands. In recent years, many new European countries started or expanded their hemp cultivation, mainly for the production of hemp seeds.
Chronic pain can be nociceptive or neuropathic. Nociceptive pain is the most common and is caused by tissue damage and inflammation. It’s characterized by throbbing, aching, and sharp pain. Neuropathic pain is caused by damage to the nervous system and can feel like stabbing, burning, or tingling pain. Studies on cannabinoids and pain demonstrate that CBD can treat both types of pain.
Cannabidiol can be taken into the body in multiple ways, including by inhalation of cannabis smoke or vapor, as an aerosol spray into the cheek, and by mouth. It may be supplied as CBD oil containing only CBD as the active ingredient (no added tetrahydrocannabinol [THC] or terpenes), a full-plant CBD-dominant hemp extract oil, capsules, dried cannabis, or as a prescription liquid solution. CBD does not have the same psychoactivity as THC, and may affect the actions of THC. Although in vitro studies indicate CBD may interact with different biological targets, including cannabinoid receptors and other neurotransmitter receptors,as of 2018 the mechanism of action for its biological effects has not been determined.
Cannabidiol is insoluble in water but soluble in organic solvents such as pentane. At room temperature, it is a colorless crystalline solid. In strongly basic media and the presence of air, it is oxidized to a quinone. Under acidic conditions it cyclizes to THC, which also occurs during pyrolysis (smoking). The synthesis of cannabidiol has been accomplished by several research groups.
In 2015, The Hebrew University of Israel published a study that documented the potency of single-molecule CBD extract versus the potency of whole-plant CBD-rich extract. It found that extract taken from whole plant CBD-rich cannabis is therapeutically superior to single-molecule extract. The scientists behind this study noticed that science had been utilizing pure, single-molecule CBD, which resulted in a bell-shaped dose-response curve. This means that CBD’s efficacy plummets at very high and very low doses.
When formulating a CBD regimen for a specific disease or illness (like chronic or neurological pain), it’s important to understand that CBD should be used regularly for maximum relief. Meaning it should be used as a preventative first – it can also be used to manage acute flare ups, but the preventative maintenance is most important! Think about it like any other dietary supplement, you want to establish a baseline concentration in your system.

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.
