The Effects of Cannabinoids on Sleep, Bhanu Prakash Kolla et al., 2022

The Effects of Cannabinoids on Sleep Bhanu Prakash Kolla, Lisa Hayes, Chaun Cox, Lindy Eatwell, Mark Deyo-Svendsen , and Meghna P. Mansukhani Journal of Primary Care & Community Health, 2022, Volume 13, 1–9. Doi : 10.1177/21501319221081277 Abstract The use of cannabis products to help with sleep and various other medical conditions by the public has increased significantly in recent years. Withdrawal from cannabinoids can lead to sleep disturbance. Here, we describe a patient who developed significant insomnia leading to worsening anxiety, mood, and suicidal ideation in the setting of medical cannabis withdrawal, prompting presentation to the Emergency Department and inpatient admission. There is a limited [...]

Cannabis is indigenous to Europe and cultivation began during the Copper or Bronze age: a probabilistic synthesis of fossil pollen studies, John M. McPartland et al., 2017

Cannabis is indigenous to Europe and cultivation began during the Copper or Bronze age: a probabilistic synthesis of fossil pollen studies John M. McPartland · Geoffrey W. Guy · William Hegman Vegetation History and Archaeobotany, 2018, 27, 635–648 Doi : 10.1007/s00334-018-0678-7   Abstract Conventional wisdom states Cannabis sativa originated in Asia and its dispersal to Europe depended upon human transport. Various Neolithic or Bronze age groups have been named as pioneer cultivators. These theses were tested by examining fossil pollen studies (FPSs), obtained from the European Pollen Database. Many FPSs report Cannabis or Humulus (C/H) with collective names (e.g. Cannabis/Humulus or Cannabaceae). To dissect these aggregate [...]

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 [...]

Contaminants of Concern in Cannabis : Microbes, Heavy Metals and Pesticides John M. McPartland and Kevin J. McKernan, 2017

Contaminants of Concern in Cannabis : Microbes, Heavy Metals and Pesticides John M. McPartland and Kevin J. McKernan in S. Chandra et al. (eds.), Cannabis sativa L. - Botany and Biotechnology, Chapter 22, 2017, 457-474. Doi : 10.1007/978-3-319-54564-6_22 Abstract Microbiological contaminants pose a potential threat to cannabis consumers. Bacteria and fungi may cause opportunistic infections in immuno-compromized individuals. Even dead organisms may trigger allergies and asthma. Toxins from microbial overloads, such as Shigla toxin and aflatoxins, may pose a problem—unlikely, but possible. The Cannabis plant hosts a robust microbiome; the identification of these organisms is underway. Cannabis bioaccumulates heavy metals in its tissues, so avidly [...]

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. [...]

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 [...]

Assessing the treatment of cannabidiolic acid methyl ester: a stable synthetic analogue of cannabidiolic acid on c‑Fos and NeuN expression in the hypothalamus of rats Eric Murillo‑Rodríguez, Roger G. Pertwee, Raphael Mechoulam et al., 2021

Assessing the treatment of cannabidiolic acid methyl ester: a stable synthetic analogue of cannabidiolic acid on c‑Fos and NeuN expression in the hypothalamus of rats Eric Murillo‑Rodríguez, Diana Millán‑Aldaco, Gloria Arankowsky‑Sandoval, Tetsuya Yamamoto, Roger G. Pertwee, Linda Parker and Raphael Mechoulam     Abstract Background : Cannabidiol (CBD), the non-psychotropic compound from Cannabis sativa, shows positive results on controlling several health disturbances; however, comparable data regarding additional chemical from C. sativa, such as cannabidiolic acid (CBDA), is scarce due to its instability. To address this limitation, a stable CBDA analogue, CBDA methyl ester (HU-580), was synthetized and showed CBDA-like effects. Recently, we described that HU-580 increased [...]

Powerful substances in tiny amounts: Exploring the practice of microdosing psychedelic drugs, Petter Grahl Johnstad, 2017

Powerful substances in tiny amounts: Exploring the practice of microdosing psychedelic drugs Petter Grahl Johnstad, Pré-Print, 2017.   This article presents an explorative study of microdosing practices with psychedelic drugs. A microdose is defined as a sub-perceptual dose, commonly about one tenth of an ordinary recreational dose, which gives no alteration of consciousness or feeling of intoxication. Respondents (n = 17) were recruited at several Internet fora for individual interviews mediated via private messaging. Every participant was male, and the median respondent was in his 30s with a stable job and relationship and extensive entheogen experience. Respondents tended to experiment with microdosing in phases, [...]

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 [...]
