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 [...]

The Case for the Entourage Effect and Conventional Breeding of Clinical Cannabis: No “Strain,” No Gain, Ethan B. Russo,

The Case for the Entourage Effect and Conventional Breeding of Clinical Cannabis: No “Strain,” No Gain Ethan B. Russo Frontiers in Plant Science, 2019, Volume 9, Article 1969, 1-8. Doi : 10.3389/fpls.2018.01969 The topic of Cannabis curries controversy in every sphere of influence, whether politics, pharmacology, applied therapeutics or even botanical taxonomy. Debate as to the speciation of Cannabis, or a lack thereof, has swirled for more than 250 years. Because all Cannabis types are eminently capable of cross-breeding to produce fertile progeny, it is unlikely that any clear winner will emerge between the “lumpers” vs. “splitters” in this taxonomical debate. This is compounded [...]

Cannabis Domestication, Breeding History, Present-day Genetic Diversity, and Future Prospects, Robert C. Clarke and Mark D. Merlin, 2016

Cannabis Domestication, Breeding History, Present-day Genetic Diversity, and Future Prospects Robert C. Clarke and Mark D. Merlin CRITICAL REVIEWS IN PLANT SCIENCES, 2016, VOL. 35, NOS. 5–6, 293–327 Doi : 10.1080/07352689.2016.1267498   ABSTRACT Humans and the Cannabis plant share an intimate history spanning millennia. Humans spread Cannabis from its Eurasian homelands throughout much of the world, and, in concert with local climatic and human cultural parameters, created traditional landrace varieties (cultivars resulting from a combination of natural and farmer selection) with few apparent signs of domestication. Cannabis breeders combined populations from widely divergent geographical regions and gene pools to develop economically valuable fiber, seed, and drug cultivars, [...]

Terpenoids From Cannabis Do Not Mediate an Entourage Effect by Acting at Cannabinoid Receptors, David B. Finlay et al., 2020

Terpenoids From Cannabis Do Not Mediate an Entourage Effect by Acting at Cannabinoid Receptors David B. Finlay, Kathleen J. Sircombe, Mhairi Nimick, Callum Jones and Michelle Glass Frontiers in Pharmacology, 2020, Volume 11, Article 359, 1-9. doi : 10.3389/fphar.2020.00359   The entourage effect was a proposed explanation for biological observations that endocannabinoid ligand activities can be modified by other lipids released from cells at the same time. An increasing volume of anecdotal reports and interest in the plant have provoked research into the activity of minor chemical constituents of the plant—including volatile terpenoids such as myrcene, a- and b- pinene, b-caryophyllene, and limonene. However, to [...]

Early Consumption of Cannabinoids : From Adult Neurogenesis to Behavior, Citlalli Netzahualcoyotzi et al., 2021

Early Consumption of Cannabinoids : From Adult Neurogenesis to Behavior Citlalli Netzahualcoyotzi, Luis Miguel Rodríguez-Serrano, María Elena Chávez-Hernández and Mario Humberto Buenrostro-Jáuregui International Journal of Molecular Sciences, 2021, 22, 7450. doi : 10.3390/ijms22147450   Abstract The endocannabinoid system (ECS) is a crucial modulatory system in which interest has been increasing, particularly regarding the regulation of behavior and neuroplasticity. The adolescent–young adulthood phase of development comprises a critical period in the maturation of the nervous system and the ECS. Neurogenesis occurs in discrete regions of the adult brain, and this process is linked to the modulation of some behaviors. Since marijuana (cannabis) is the most consumed illegal [...]

Cannabinoid Addiction: Behavioral Models and Neural Correlates, Rafael Maldonado et al., 2002

Cannabinoid Addiction: Behavioral Models and Neural Correlates Rafael Maldonado and Fernando Rodriguez de Fonseca The Journal of Neuroscience, 2002, 22, (9), 3326–3331. Abstract The use of cannabis sativa preparations as recreational drugs can be traced back to the earliest civilizations. However, animal models of cannabinoid addiction allowing the exploration of neural correlates of cannabinoid abuse have been developed only recently. We review these models and the role of the CB1 cannabinoid receptor, the main target of natural cannabinoids, and its interaction with opioid and dopamine transmission in reward circuits. Extensive reviews on the molecular basis of cannabinoid action are available elsewhere (Piomelli et al., [...]

Cannabinoids and the endocannabinoid system in reward processing and addiction: from mechanisms to interventions, Rainer Spanagel, 2020

Cannabinoids and the endocannabinoid system in reward processing and addiction: from mechanisms to interventions Rainer Spanagel, PhD Dialogues in Clinical Neuroscience, 2020, 22, (3), 241-250. doi : 10.31887/DCNS.2020.22.3/rspanagel   The last decades have seen a major gain in understanding the action of cannabinoids and the endocannabinoid system in reward processing and the development of addictive behavior. Cannabis-derived psychoactive compounds such as Δ9-tetrahydrocannabinol and synthetic cannabinoids directly interact with the reward system and thereby have addictive properties. Cannabinoids induce their reinforcing properties by an increase in tonic dopamine levels through a cannabinoid type 1 (CB1) receptor–dependent mechanism within the ventral tegmental area. Cues that are conditioned [...]

Current state of evidence of cannabis utilization for treatment of autism spectrum disorders, Rumi Agarwal et al., 2019

Current state of evidence of cannabis utilization for treatment of autism spectrum disorders Rumi Agarwal, Shanna L. Burke and Marlaina Maddux BMC Psychiatry, 2019, 19, 328 Doi : 10.1186/s12888-019-2259-4   Abstract The core symptoms and co-morbidities associated with autism spectrum disorders (ASD) affect daily living and quality of life. Existing pharmacological interventions are only able to attenuate some related symptoms but are unable to address the underlying etiologies associated with ASD. Anecdotal evidence, which claims benefit from the use of cannabis to treat symptoms among this population, has been gaining popularity as families seek solutions. This paper analyzed recent peer-reviewed literature to identify the current state of [...]
