On the 23rd of July The Center for the Study of Cannabis and Social Policy (CASP) organized the 2nd annual Terpestival in Hopland CA.
The festival’s main goal is to was designed to educate the public on the contribution of terpenoids to cannabis plant-based medicine. The keynote speaker was Dr. Ethan Russo who had a presentation entitled “Terpenoids and Cannabinoids.” There were several interesting panels all concentrated around the importance of terpenes in the hemp plant.
As the name suggest, in the The Terpene Tournament™, the terpens were the stars of the show while cannabinoid content was not so relevant. All the flowers and CO2 concentrates were tested to determine the cannabinoid and terpene content. The average flower terpene content was 1.4%, due to the loss of terpene content from harvest time. The average terpene content in concentrates was 9,7%.
An important take-away message from the event was that cannabis shouldn’t be defined only by the cannabinoid profile. Terpenes and other aromatic molecules give cannabis its distinct taste/smell and are very important not only for their medicinal value but also for the enhancement of the connoisseur experience.

In a recently published article by Hanuš et al. (1), three new cannabinoids have been identified from a sample of Indian hashish; cannabiorcochromene, cis-D9-tetrahydrocannabivarol and cannabinerol.
The study focused on identifying the main cannabinoid content of hashish samples from Morocco, Lebanon and India seized by Czech and Israel police forces. In the Indian sample from the Czech republic they also preformed a quantitative analysis of cannabinoids and terpenes which led to the identification of the three new cannabinoids. This brings the total number of cannabinoids identified in the cannabis plant to 120, although according to Dr. Hanuš lectures, the total sum is higher, amounting to 144 identified cannabinoids (Hanuš, march 2016).
Analysis of the the different hashish samples from Lebanon, Morocco and India also showed some interesting results. In Lebanese hashish the content of CBD was high and THC was low (2-3:1 CBD:THC ratio) while the Moroccan samples showed the opposite, high in THC and low in CBD (1:2-3 CBD:THC ratio). Indian hashish had a mixed range of ratios but showed higher
amounts of propylcannabinoids, such as D9-tetrahydrocannabivarin
(THCV) or cannabivarin (CBV). From the results of the analysis, hashish of Lebanese origin was indicative of fiber-type phenotype and Moroccan pf the drug-type phenotype.
