Despite growing knowledge of the pathological mechanisms that underlie the development of these disorders, a high percentage of patients do not respond to first-line clinical treatments; thus, there is a strong need for alternative therapeutic approaches. During the past half-century, after the identification of the [...]

Lire la suiteCannabis and Depression Daniel Feingold, Aviv Weinstein Advances in Experimental medicine and Biology, 2021, 1264, 67-80. In book : "Cannabinoids and Neuropsychiatric Disorders", Aviv Weinstein 's Lab Doi : 10.1007/978-3-030-57369-0_5 Abstract There is a growing body of evidence pointing to the co-occurrence of cannabis use and depression. There is also some evidence that the use of cannabis may lead to the onset of depression; however, strong evidence points to the inverse association; i.e. that depression may lead to the onset or increase in cannabis use frequency. Observational and epidemiological studies have not indicated a positive long-term effect of cannabis use on the course and outcome of [...]

R. Arkell, F. Vinckenbosch, J. Schepers, R. C. Kevin, E. L. Theunissen, K. P. C. Kuypers, I. S. McGregor, J. G. Ramaekers Psychopharmacology, 2022, 239, 3731–3741 Doi : 10.1007/s00213-022-06248-9 Abstract Rationale : Delta-9-tetrahydrocannabinol (THC), an active component of cannabis, can cause anxiety in some users during intoxication. Cannabidiol (CBD), another constituent of cannabis, has anxiolytic properties suggesting that cannabis products containing CBD in addition to THC may produce less anxiety than THC-only products. Findings to date around this issue have been inconclusive and [...]
