Cannabinoids Sample Clauses

Cannabinoids. A. The following cannabinoids are approved for use in lower-potency hemp edibles: hemp-derived delta-9 tetrahydrocannabinol. B. The following cannabinoids are designated as nonintoxicating: (1) cannabichromene (CBC); (2) cannabidiol (CBD); (3) cannabigerol (CBG); and (4) cannabinol (CBN).

Cannabinoids. In recent years there has been exponential increase in the interest among physicians and the general public about the potential of cannabinoids, cannabidiol in particular, for the treatment of epilepsy (▇▇▇▇▇▇▇, 2017). Class I evidence is now available indicating that cannabidiol added on to other antiepileptic drugs (AEDs) improves seizure control in patients with Dravet syndrome (Devinsky et al. 2017) and Lennox- Gastaut-syndrome (Devinsky et al, 2018; ▇▇▇▇▇▇ et al, 2018), but high-quality evidence for its potential usefulness in the management of other epilepsy syndromes is still lacking. The results of the present survey show that exploration of the potential value of cannabidiol in a wide range of other seizure types and epileptic syndromes remains a high priority in the epilepsy community. It has also been suggested that the combination of cannabidiol and tetrahydrocannabidiol could bring antiseizure benefits superior to those associated with cannabidiol alone (▇▇▇▇▇ et al, 2018), and assessment of the potential added value of this combination was also recommended by one survey participant. The WP V TF concurred that high quality trials on the value of cannabinoids in epilepsy are worth pursuing. There was consensus that any such trial should make use of pharmaceutical-grade formulations, because there is evidence that some commercially available artisanal products may not contain the stated amount of cannabinoids, and may even contain harmful contaminants (▇▇▇▇▇▇▇, 2017).

Cannabinoids. Those chemical substances that link with the cannabinoid receptors of the body and the brain, and they can be classified in Phytocannabinoids, Endocannabinoids and synthetic Cannabinoids, among the most common Phytocannabinoids we have: CBD (Cannabidiol), CBN (Cannabinol), CBG (Cannabigerol) and THC (Tetrahydrocannabinol).

Cannabinoids. This group represents the most studied compounds from cannabis. The term cannabinoid is given to the terpenophenolic compounds with 22 carbons (or 21 carbons for neutral form) of which 70 cannabinoids have been found so far and which can be divided into 10 main structural types (Figure 1). All other compounds that do not fit into the main types are grouped as miscellaneous (Figure 2). The neutral compounds are formed by decarboxylation of the unstable corresponding acids. Although decarboxylation occurs in the living plant, it increases during storage after harvesting, especially at elevated temperatures (Mechoulam and ▇▇▇-▇▇▇▇▇▇, 1999). Both forms are also further degraded into secondary products by the effects of temperature, light (▇▇▇▇▇ and ▇▇▇▇▇▇, 1978) and auto-oxidation (▇▇▇▇▇▇ et al., 1972).

Cannabinoid structural types. In cannabis, the most prevalent compounds are Δ9-THC acid, CBD acid and CBN acid, followed by CBG acid, CBC acid and CBND acid, while the others are minor compounds. Based on the absolute concentration of Δ9-THC (Δ9-THC+ Δ9-THC acid) and CBD (CBD + CBD acid) obtained via HPLC or GC analyses, the plants are classified as follows: Drug type (chemotype I), the concentration of Δ9-THC is more than 2% and CBD concentration is less 0.5%; Fiber type (chemotype III), the Δ9-THC concentration is less than 0.3% and the concentration of CBD is more than 0.5%; Intermediate type (chemotype II), the concentrations of both are similar, usually more than 0.5% for each; and Propyl isomer/C3 type (chemotype IV), which can be differentiated by the d...
