Increased cannabis intake during the COVID-19 pandemic is associated with worsening of depression symptoms in people with PTSD A. Murkar, T. Kendzerska, J. Shlik, L. Quilty, M. Saad and R. Robillard BMC Psychiatry, 2022, 22, 554 Doi : 10.1186/s12888-022-04185-7   Abstract Background: Some evidence suggests substance use affects clinical outcomes in people with posttraumatic stress disorder (PTSD). However, more work is required to examine links between mental health and cannabis use in PTSD during exposure to external stressors such as the COVID-19 pandemic. This study assessed mental health factors in individuals with self-reported PTSD to: (a) determine whether stress, anxiety, and depression symptoms were associ- ated with changes [...]

Cannabis containing equivalent concentrations of delta‐9‐tetrahydrocannabinol (THC) and cannabidiol (CBD) induces less state anxiety than THC‐dominant cannabis Nadia R. P. W. Hutten, T. 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 [...]

Cannabis in the management of PTSD : a systematic review, Yasir Rehman et al., 2021

Cannabis in the management of PTSD : a systematic review, Yasir Rehman, Amreen Saini, Sarina Huang, Emma Sood, Ravneet Gill and Sezgi Yanikomeroglu AIMS Neuroscience, 2021, 8, (3), 414-434. Doi : 10.3934/Neuroscience.2021022   Abstract : Introduction : Existing reviews exploring cannabis effectiveness have numerous limitations including narrow search strategies. We systematically explored cannabis effects on PTSD symptoms, quality of life (QOL), and return to work (RTW). We also investigated harm outcomes such as adverse effects and dropouts due to adverse effects, inefficacy, and all-cause dropout rates. Methods : Our search in MEDLINE, EMBASE, PsycInfo, CINAHL, Web of Science, CENTRAL, and PubMed databases, yielded 1 eligible RCT and 10 [...]

Endocannabinoid System as Therapeutic Target of PTSD : A Systematic Review, Luca Steardo, Jr. et al., 2021

Endocannabinoid System as Therapeutic Target of PTSD : A Systematic Review Luca Steardo, Jr., Elvira Anna Carbone, Giulia Menculini, Patrizia Moretti, Luca Steardo and Alfonso Tortorella Life, 2021, 11, 214. Doi : 10.3390/life11030214 Abstract : Post-Traumatic Stress Disorder (PTSD) is a complex disorder involving dysregulation of stress-related hormones and neurotransmitter systems. Research focused on the endocannabinoid system (eCBS) for anxiety and stress regulation, cognitive and emotional responses modulation and aversive memories extinction, leading to the hypothesis that it could represent a possible alternative treatment target for PTSD. In this systematic review, we summarize evidence about the efficacy and safety of medicinal cannabidiol (CBD), D9-tetrahydrocannabinol (D9-THC), and [...]

Cannabinoids and Neurogenesis : The Promised Solution for Neurodegeneration ?, Andrea Valeri and Emanuela Mazzon, 2021

Cannabinoids and Neurogenesis : The Promised Solution for Neurodegeneration ? Andrea Valeri and Emanuela Mazzon Molecules, 2021, 26, 6313, 1-26. doi : 10.3390/molecules26206313   Abstract : The concept of neurons as irreplaceable cells does not hold true today. Experiments and evidence of neurogenesis, also, in the adult brain give hope that some compounds or drugs can enhance this process, helping to reverse the outcomes of diseases or traumas that once were thought to be everlasting. Cannabinoids, both from natural and artificial origins, already proved to have several beneficial effects (e.g., anti-inflammatory, anti-oxidants and analgesic action), but also capacity to increase neuronal population, by replacing the [...]
