The Scythians then take the seed of this hemp and creep under the felt coverings, and then they throw the seed upon the stones which have been heated red-hot: and it burns like incense and produces a vapour so think that no vapour-bath in Hellas would surpass it: and the Scythians being delighted with the vapour-bath howl like wolves.

Cannabidiol, a novel inverse agonist for GPR3, GPR6, and GPR12 GPR3, GPR6, and GPR12 are constitutively active, Gs protein- coupled receptor that currently have no confirmed endogenous ligands. GPR3, GPR6, and GPR12 may be involved in physiological processes such as maintenance of oocyte meiotic arrest and brain development, as well as pathological conditions such as metastatic cancer. Cannabidiol (CBD), a major non-psychoactive phytocannabinoid, acted as an inverse agonist to inhibit cAMP accumulation stimulated by the constitutively active GPR3, GPR6, and GPR12. Thus, GPR3, GPR6, and GPR12 are novel molecular targets for CBD. Gs, but not Gi is involved in the inverse agonism of CBD on GPR3, GPR6, and GPR12 . Laun et al., 2018 Tetrahydrocannabinolic acid is a potent peroxisome proliferator-activated receptor gamma (PPARg) agonist with neuroprotective activity Cannabinoid acids are more potent PPARγ agonists and transcriptional activators than their decarboxylated analogues. Crystal Structure of Human PAPRα complex with agonist D9-THCA shows potent neuroprotective activity, which is worth considering for the treatment of Huntington’s disease and possibly other neurodegenerative and neuroinflammatory diseases. These data would strongly suggest Δ9-THCA as a lead structure for the development of novel drugs. Nadal et al., 2017 Endocannabinoids Anandamide William A.

  • Israeli Cannabis Company 'Together' Announced an Agreement with a Canadian Company to Sell 50 Tons of Cannabis Inflorescences Or 5 Tons of Cannabis Oil
    Israeli cannabis company 'Together' announced an agreement with a Canadian company to sell 50 tons of cannabis inflorescences or 5 tons of cannabis oil The company estimates the potential annual revenue from the deal at hundreds of millions of shekels. "This agreement joins other existing sales agreements in Canada and German totaling 30 tons. These agreements ensure the creation of revenue and cash flow that are not dependent on export approval from the State of Israel, and which will derive from the sale of medical cannabis and its products from areas that we will set up in countries outside of Israel that have the relevant export agreements", said Globus Pharma founding partner Nissim Bracha Israel, Ashkelon, April 11 2018 – 'Together' (TASE: TGTR) announced that its activity company 'Globus Pharma', which specializes in the medical cannabis sector and operates as a subsidiary of 'Together', has signed a Memorandum of Understanding (MoU) to sell medical cannabis or oil to a Canadian company with a license to grow, produce and import medical cannabis to Canada. Under the terms of the agreement, the Canadian company will buy from Globus 50 tons of dried inflorescences of cannabis each year or five tons of medical cannabis oil (the equivalent amount to 50 tons of inflorescences) as part of the terms of the law in Canada and in Israel. In addition, the two companies will collaborate in the field of R&D and promoting technologies in the medical cannabis sector. As of the date of signing the agreement, the parties estimate that sales revenue will amount to between US$3.17 and US$4.7 per gram of inflorescence.

  • Israel Takes the Next Steps Towards Legalizing Recreational Cannabis
    Article Cannabis Law July 2020 Israel Takes the Next Steps Towards Legalizing Recreational Cannabis By Andrew J. Wilder and Jonathan Mahoney Israel is considered one of the global leaders in medical cannabis research and innovation. In 1964, Professor Raphael Mechoulam of the Hebrew University of Jerusalem was the first person to isolate and identify THC, the psychoactive chemical component in cannabis that causes a high. While limited use of cannabis for medicinal purposes has been permitted in Israel since the early 1990s, it took 53 years from Professor Mechoulam’s breakthrough before the Public Security Ministry partially decriminalized cannabis in 2017, setting fines and treatment for initial offenders instead of criminal procedures. Earlier this year, after much bureaucratic delay, the export of medical cannabis was finally approved and is estimated to generate hundreds of millions of dollars in revenue annually. Now, three years since its decriminalization, Israel is on the verge of legalizing cannabis for recreational use. On June 9th, 2020, just one week after the State of Israel police minister declared that enforcement of the existing laws related to cannabis possession and use would be relaxed, two of Israel’s largest political parties issued a joint statement, agreeing to move forward with cannabis law reform. In the joint statement provided by Likud Prime Minister Benjamin Netanyahu and Blue and White’s Defense Minister Benny Gantz, they advised that reform to existing legislation was required with the aim to “resolve the issue of decriminalization and legalization” of cannabis in Israel. In addition to legalizing recreational cannabis, the proposed reforms will also make it easier for patients to gain access to treatment and for producers to become licensed to grow and sell medical cannabis.

    Vol. 49 No. 2 February 2015 Journal of Pain and Symptom Management 223 Original Article Patterns of Use of Medical Cannabis Among Israeli Cancer Patients: A Single Institution Experience Barliz Waissengrin, MD, Damien Urban, MD, Yasmin Leshem, MD, Meital Garty, BA, and Ido Wolf, MD Institute of Oncology (B.W., M.G., I.W.), Tel Aviv Sourasky Medical Center, Tel Aviv; Institute of Oncology (D.U., Y.L.), Chaim Sheba Medical Center, Ramat Gan; and Sackler Faculty of Medicine (I.W.), Tel Aviv University, Tel Aviv, Israel Abstract Context. The use of the cannabis plant (Cannabis sativa L.) for the palliative treatment of cancer patients has been legalized in multiple jurisdictions including Israel. Yet, not much is currently known regarding the efficacy and patterns of use of cannabis in this setting. Objectives. To analyze the indications for the administration of cannabis among adult Israeli cancer patients and evaluate its efficacy. Methods. Efficacy and patterns of use of cannabis were evaluated using physician-completed application forms, medical files, and a detailed questionnaire in adult cancer patients treated at a single institution. Results. Of approximately 17,000 cancer patients seen, 279 (<1.7%) received a permit for cannabis from an authorized institutional oncologist. The median age of cannabis users was 60 years (range 19e93 years), 160 (57%) were female, and 234 (84%) had metastatic disease. Of 151 (54%) patients alive at six months, 70 (46%) renewed their cannabis permit. Renewal was more common among younger patients and those with metastatic disease. Of 113 patients alive and using cannabis at one month, 69 (61%) responded to the detailed questionnaire.

  • Cannabis Brands
    Intro-Blue, LLC | 617-454-1088 | [email protected] | www.intro-blue.com | Volume 54 | 7/29/20 CANNABIS BRANDS – THE RACE FOR THE TOP SPOT HAS JUST BEGUN In our June 24 Stash report, we discussed why brand presence, shelf space, and market share are among the key KPIs for cannabis investors to monitor. We had also highlighted that cannabis brands are a state-specific asset, with no dominant brand across U.S. states, suggesting that local brands currently have an edge over national players that are yet to establish themselves as the number one choice of consumers. Our thesis was supported by a July 7 news article in the Marijuana Business Daily which found that the addition in number of cannabis brands in the U.S. is outpacing the increase in retail store count, resulting in increased competition for retail shelf space in key adult-use markets. This is forcing brands to pay slotting fees ranging from $500 to $15,000 per month for premium space on cannabis retailers’ shelves. This pay-to-play practice/slotting fees – especially in key in key states like California and Nevada – has gathered pace with the rise in popularity of cannabis products (especially vape products), implying that consumers are relatively more brand conscious while buying cannabis in other product formats vs. when buying dried flower. Lack of dominant brands is a reality in the Canadian market too, as brand awareness is not translating into higher sales with consumers basing their purchase decisions on price rather than brand names or packaging. Canada legalized sale of cannabis products – Cannabis 2.0 – in December 2019 and a survey of 3,000 cannabis consumers by Brightfield Group found that despite the brand building push by most LPs, the vast majority of brands have awareness levels ranging between just 1% and 15%.
