Cannabis sativa research trends, challenges, and new-age perspectives, Tajammul Hussain et al., 2021

Cannabis sativa research trends, challenges, and new-age perspectives Tajammul Hussain, Ganga Jeena, Thanet Pitakbut, Nikolay Vasilev, and Oliver Kayser iScience, Cell Press, 2021,24, 103391, 1-13. Doi : 10.1016/j.isci.2021.103391   SUMMARY Cannabis sativa L. has been one of the oldest medicinal plants cultivated for 10,000 years for several agricultural and industrial applications. However, the plant became controversial owing to some psychoactive components that have adverse effects on human health. In this review, we analyzed the trends in cannabis research for the past two centuries. We discussed the historical transitions of cannabis from the category of herbal medicine to an illicit drug and back to a medicinal product post-legalization. [...]

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, [...]

Genomic and Chemical Diversity in Cannabis, C. Lynch et al., 2015

Genomic and Chemical Diversity in Cannabis Ryan C. Lyncha,e, Daniela Vergaraa, Silas Tittesa, Kristin Whitea, C. J. Schwartzb, Matthew J. Gibbsb, Travis C. Ruthenburgc,d, Kymron deCesarec, Donald P. Landc, and Nolan C. Kanea CRITICAL REVIEWS IN PLANT SCIENCES, 2016, VOL. 35, NOS. 5–6, 349–363 Doi : 10.1080/07352689.2016.1265363 ABSTRACT Plants of the Cannabis genus are the only prolific producers of phytocannabinoids, compounds that strongly interact with the evolutionarily ancient endocannabinoid receptors shared by most bilaterian taxa. For millennia, the plant has been cultivated not only for these compounds, but also for food, rope, paper, and clothing. Today, specialized varieties yielding high-quality textile fibers, nutritional seed oil, or high cannabinoid [...]

Classic psychedelics in the treatment of substance use disorder: Potential synergies with twelve-step programs, David B. Yaden et al., 2021

Classic psychedelics in the treatment of substance use disorder: Potential synergies with twelve-step programs David B. Yaden, Andrea P. Berghella, Paul S. Regier, Albert Garcia-Romeu, Matthew W. Johnson, Peter S. Hendricks International Journal of Drug Policy, 2021, Doi : 10.1016/j.drugpo.2021.103380   a b s t r a c t Several pilot studies have provided evidence supporting the potential of classic psychedelics like psilocybin in the treatment of substance use disorders (SUDs). If larger trials confirm efficacy, classic psychedelic-assisted psychotherapy may eventually be integrated into existing addiction treatments such as cognitive behavioral therapy, contingency management, and medication-assisted therapies. Many individuals seeking treatment for SUDs also join twelve-step [...]

Psychedelic-Assisted Group Therapy : A Systematic Review, Alexander Trope et al., 2019

Psychedelic-Assisted Group Therapy : A Systematic Review Alexander Trope, Brian T. Anderson, Andrew R. Hooker, Giancarlo Glick, Christopher Stauffer, Joshua D. Woolley Journal of Psychoactive Drugs, 2019, 51, (2) 174–188. doi : 10.1080/02791072.2019.1593559 Abstract Contemporary research with classic psychedelic drugs (e.g. lysergic acid diethylamide (LSD) and psilocybin) is indebted to the 20th century researchers and clinicians who generated valuable clinical knowledge of these substances through experimentation. Several recent reviews that highlight the contributions of this early literature have focused on psychedelic-assisted individual psychotherapy modalities. None have attempted to systematically identify and compile experimental studies of psychedelic-assisted group therapy. In therapeutic settings, psychedelics were often used [...]

On the Relationship between Classic Psychedelics and Suicidality : A Systematic Review, Richard J. Zeifman et al., 2021

On the Relationship between Classic Psychedelics and Suicidality : A Systematic Review Richard J. Zeifman, Nikhita Singhal, Leah Breslow, & Cory R. Weissman ACS Pharmacology & Translational Science, 2021, 4, (2), 436-451 Doi : 10.1021/acsptsci.1c00024 Abstract Use of classic psychedelics (e.g., psilocybin, ayahuasca, lysergic acid diethylamide) is increasing and psychedelic therapy is receiving growing attention as a novel mental health intervention. Suicidality remains a potential safety concern associated with classic psychedelics and is, concurrently, a mental health concern that psychedelic therapy may show promise in targeting. Accordingly, further understanding of the relationship between classic psychedelics and suicidality is needed. Therefore, we conducted a systematic review [...]

Assessing the risk-benefit profile of classical psychedelics : a clinical review of second-wave psychedelic research David Bender & David J. Hellerstein Psychopharmacology (Berl), 2022. Doi : 10.1007/s00213-021-06049-6 Abstract Rationale : A broad reassessment of the potential benefits of psychedelic drugs has led to the initiation of multiple major clinical trials in an effort to advance their status to become FDA-approved medications, as well as local legislative efforts to legalize or decriminalize their use. Objectives : To use recently published data to assess potential risks and benefits of psychedelic drugs as therapeutics, as well as to synthesize what is currently known in order [...]
