The Role of Cannabis within an Emerging Perspective on Schizophrenia Jegason P. Diviant, Jacob M. Vigil, and Sarah S. Stith Medicines, 2018, 5, 86, 1-11. doi : 10.3390/medicines5030086   Abstract Background : Approximately 0.5% of the population is diagnosed with some form of schizophrenia, under the prevailing view that the pathology is best treated using pharmaceutical medications that act on monoamine receptors. Methods : We briefly review evidence on the impact of environmental forces, particularly the effect of autoimmune activity, in the expression of schizophrenic profiles and the role of Cannabis therapy for regulating immunological functioning. Results : A review of the literature shows that phytocannabinoid consumption may [...]

Cannabidiol as a potential treatment for psychosis, Cathy Davies and Sagnik Bhattacharyya, 2019

Cannabidiol as a potential treatment for psychosis Cathy Davies and Sagnik Bhattacharyya Therapeutic Advances in Psychopharmacology, 2019, Vol. 9, 1–16 https://doi.org/10.1177%2F2045125319881916   Abstract : Psychotic disorders such as schizophrenia are heterogeneous and often debilitating conditions that contribute substantially to the global burden of disease. The introduction of dopamine D2 receptor antagonists in the 1950s revolutionised the treatment of psychotic disorders and they remain the mainstay of our treatment arsenal for psychosis. However, traditional antipsychotics are associated with a number of side effects and a significant proportion of patients do not achieve an adequate remission of symptoms. There is therefore a need for novel interventions, particularly those with a non-D2 antagonist mechanism of [...]

Cannabinoids and Mental Health, Part 1 : The Endocannabinoid System and Exogenous Cannabinoids Andrew Penn Journal of Psychosocial Nursing and Mental Health Services, 2019, 57, 9, 7-10. Doi : 10.3928/02793695-20190813-01   ABSTRACT The increasing public acceptance of cannabis and the proliferation of cannabis products in the market-place has coincided with more patients using the drug as a substitute for psychiatric medications or as an adjunctive treatment modality for psychiatric conditions, despite limited evidence of efficacy. With a goal of furthering harm-reduction eff orts in psychiatric nursing, the current article reviews the fundamentals of the endocannabinoid system in humans and the exogenous phytocannabinoids that act on this regulatory [...]

Medical use of cannabis. Cannabidiol : a new light for schizophrenia ?, Serena Deiana, 2013

Medical use of cannabis. Cannabidiol: a new light for schizophrenia ? Serena Deiana Drug Testing and Analysis, 2013, 5, (1), 46-51 doi: 10.1002/dta.1425. Abstract The medical properties of cannabis have been known for many centuries; its first documented use dates back to 2800 BC when it was described for its hallucinogenic and pain-relieving properties. In the first half of the twentieth century, a number of pharmaceutical companies marked cannabis for indications such as asthma and pain, but since then its use has sharply declined, mainly due to its unpredictable effects, but also for socio-political issues. Recently, great attention has been directed to the medical properties [...]

Cannabidiol Counteracts the Psychotropic Side-Effects of Δ-9-Tetrahydrocannabinol in the Ventral Hippocampus through Bidirectional Control of ERK1–2 Phosphorylation, Roger Hudson et al., 2019

Cannabidiol Counteracts the Psychotropic Side-Effects of Δ-9-Tetrahydrocannabinol in the Ventral Hippocampus through Bidirectional Control of ERK1–2 Phosphorylation Roger Hudson, Justine Renard, Christopher Norris, Walter J. Rushlow and Steven R. Laviolette Journal of Neuroscience, 2019, 39, (44), 8762-8777 Doi : https://doi.org/10.1523/JNEUROSCI.0708-19.2019   Abstract Evidence suggests that the phytocannabinoids Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) differentially regulate salience attribution and psychiatric risk. The ventral hippocampus (vHipp) relays emotional salience via control of dopamine (DA) neuronal activity states, which are dysregulated in psychosis and schizophrenia. Using in vivo electrophysiology in male Sprague Dawley rats, we demonstrate that intra-vHipp THC strongly increases ventral tegmental area (VTA) DA neuronal frequency [...]

Clinicians’ Guide to Cannabidiol and Hemp Oils Harrison J. VanDolah, Brent A. Bauer, and Karen F. Mauck  Mayo Clinic Proceedings, 2019, 94, (9), 1840-1851 https://doi.org/10.1016/j.mayocp.2019.01.003   Abstract Cannabidiol (CBD) oils are low tetrahydrocannabinol products derived from Cannabis sativa that have become very popular over the past few years. Patients report relief for a variety of conditions, particularly pain, without the intoxicating adverse effects of medical marijuana. In June 2018, the first CBD-based drug, Epidiolex, was approved by the US Food and Drug Administration for treatment of rare, severe epilepsy, further putting the spotlight on CBD and hemp oils. There is a growing body of preclinical and [...]
