Cannabis and mental illness : a review Darby J. E. Lowe · Julia D. Sasiadek · Alexandria S. Coles · Tony P. George European Archives of Psychiatry and Clinical Neuroscience, 2018, 1-14. Doi : 10.1007/s00406-018-0970-7 Abstract With the increasing push to legalize cannabis in Western nations, there is a need to gage the potential impact of this policy change on vulnerable populations, such as those with mental illness, including schizophrenia, mood, and anxiety disorders. This is particularly important as there are strong motives in these individuals to seek short-term reward (e.g., “getting high”). Nonetheless, data to support the beneficial effects of cannabis use in psychiatric [...]

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 [...]

Lire la suiteCannabis 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 [...]
Lire la suiteThe 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 [...]
Lire la suiteContaminants 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 [...]
