France is Europe's biggest producer (and the world's second largest producer) with 8,000 hectares (20,000 acres) cultivated. 70–80% of the hemp fibre produced in 2003 was used for specialty pulp for cigarette papers and technical applications. About 15% was used in the automotive sector, and 5-6% was used for insulation mats. About 95% of hurds were used as animal bedding, while almost 5% was used in the building sector. In 2010/2011, a total of 11,000 hectares (27,000 acres) was cultivated with hemp in the EU, a decline compared with previous year.
The cannabis plant contains hundreds of different phytochemicals including cannabinoids, terpenes, and other compounds. Full spectrum CBD or hemp oil generally refers to products that not only contain CBD but contain the other plant molecules as well. This version of CBD oil is minimally refined, leaving most of the cannabinoids and terpenes intact and in the oil.
Industrial hemp farmers tend to aim to grow the plants up, not out as is the case with medicinal cannabis – and the taller, the better. This is because some of the great value of industrial hemp in fibre based applications is primarily in its stalk rather than leaves. Industrial hemp is grown at quite high density – another major difference to the cultivation of subsp. indica.
CBD is a chemical compound found in the cannabis and hemp plants. In order to obtain CBD from the plant, so it can be formulated as a tincture or infused into another product, it must be extracted from the plant material. There are other chemical compounds found in cannabis and hemp. In this context, cannabinoids and terpenes are the most significant of these compounds.
https://www.ncbi.nlm.nih.gov/pubmed/19045957 The nonpsychoactive Cannabis constituent cannabidiol is a wake-inducing agent. lateral hypothalamus or dorsal raphe nuclei, which are wake-inducing brain areas which cannabidiol enhances wakefulness and decreases slow wave sleep and REM sleep. Furthermore, cannabidiol increases alpha and theta power spectra but diminishes delta power spectra. Additionally, cannabidiol increases c-Fos expression in lateral hypothalamus or dorsal raphe nueclei. These findings suggest that cannabidiol is a wake-inducing compound that presumably activates neurons in lateral hypothalamus and dorsal raphe nuclei.
The results “suggest CBD to be a potential treatment for nicotine addiction,” the study authors wrote—but they also admit that their findings are preliminary. Ryan Vandrey, PhD, a cannabis researcher and associate professor of psychiatry at Johns Hopkins University (who was not involved in the 2013 study), agrees that larger, longer-term studies are needed to know if CBD might be helpful for smokers looking to kick the habit.
