Cannabis Withdrawal Nicolas J. Schlienz and Ryan Vandrey I. D. Montoya, S. R. B. Weiss (eds.), Cannabis Use Disorders, https://doi.org/10.1007/978-3-319-90365-1_11   Introduction Drug withdrawal refers to a constellation of symptoms that occur following abrupt cessation of chronic drug use. Though drug withdrawal can occur from stopping use of medication, it is most often encountered within the context of illicit, non-medicinal, drug use. The withdrawal symptoms that emerge following extended and frequent use of abused drugs are a key feature of what define substance use disorders [4, 85].

Flavonoid Derivative of Cannabis Demonstrates Therapeutic Potential in Preclinical Models of Metastatic Pancreatic Cancer Michele Moreau, Udoka Ibeh, Kaylie Decosmo Noella Bih, Sayeda Yasmin-Karim, Ngeh Toyang, Henry Lowe5 and Wilfred Ngwa Frontiers in Oncology, July 2019, Vol. 9, article 660. doi: 10.3389/fonc.2019.00660   Abstract Pancreatic cancer is particularly refractory to modern therapies, with a 5-year survival rate for patients at a dismal 8%. One of the significant barriers to effective treatment is the immunosuppressive pancreatic tumor microenvironment and development of resistance to treatment. New treatment options to increase both the survival and quality of life of patients are urgently needed. This study reports on a new [...]

Bossong Journal of Clinical Medicine, 2019, 8, 1058 doi : 10.3390/jcm8071058 Abstract : The endogenous cannabinoid (eCB) system plays an important role in the pathophysiology of both psychotic disorders and substance use disorders (SUDs).

Psychedelic Elephant, Peter Webster, 2019

Psychedelic Elephant A critique of psychedelic research Peter Webster juillet 2019 https://www.researchgate.net/search.Search.html?type=researcher&query=Psychedelic%20Elephant   My title might lead some who are old enough to remember the incident 1 2 to expect from this essay an indictment of the idiots who conducted the "scientific research" during which an elephant was clearly murdered.3 It is always great fun to expose foolishness and willful ignorance. But unfortunately, psychedelic research in those days, the 1950s and 1960s, attracted no small number of other scientists who, at least in retrospect, could also be called idiots. Jean Houston (1967) has described one of her initial observations of LSD administration. The subject was told by [...]
