Marijuana Use Continues to Grow in Older Adults Pauline Anderson Medscape, February 26, 2020 https://www.medscape.com/viewarticle/925762?nlid=134178_2052&src=WNL_mdplsnews_200228_mscpedit_psyc&uac=292598PZ&spon=12&impID=2294726&faf=1 Cannabis use in older Americans is growing. New research shows that over a 4-year period use of the drug in individuals age 65 and older increased by 75%. Joseph J. Palamar, PhD, MPH This population is especially vulnerable to potential adverse effects from cannabis and so this population needs to understand the potential risks associated with marijuana use, study investigator Joseph J. Palamar, PhD, MPH, associate professor, Department of Population Health, New York University (NYU) Langone Medical Center, New York City, told Medscape Medical News. The findings, he added, indicate a need for more [...]

Carmen REY-SANTANO, Victoria MIELGO, Xabier MURGIA-ESTEVE, Enrique HILARIO, and Jose MARTINEZ-ORGADO Pediatric Research, 2011, 70, 272–277. ABSTRACT : Newborn piglets exposed to acute hypoxia-ischemia (HI) received i.v. cannabidiol (HI CBD) or vehicle (HI VEH). In HI VEH, 72 h post-HI brain activity as assessed by amplitudeintegrated EEG (aEEG) had only recovered to 42 9% of baseline, near-infrared spectroscopy (NIRS) parameters remained lower than normal, and neurobehavioral performance was abnormal (27.8 2.3 points, normal 36).

Lire la suiteReported effects of psychedelic use on those with low well-being given various emotional states and social contexts Natasha L. Mason, Patrick C. Dolder and Kim P.C. Kuypers Drug Science, Policy and Law, 2020, Volume 6, 1–11. Doi : 10.1177/2050324519900068 Abstract Background : It has been suggested that the outcome of the psychedelic experience is dependent on set and setting. While scientific research into the therapeutic potential of psychedelics is growing, it is clear that in clinical populations an optimal set and setting will not always be attainable. It was aimed to assess under which emotional and environmental circumstances psychedelic users use psychedelics, and the outcome [...]

O’Sullivan JCI Insight, 2017, 2, (11), e93760 Doi : 10.1172/jci.insight.93760 BACKGROUND. Cannabidiol (CBD) is a nonpsychoactive phytocannabinoid used in multiple sclerosis and intractable epilepsies. Preclinical studies show CBD has numerous cardiovascular benefits, including a reduced blood pressure (BP) response to stress. The aim of this study was to investigate if CBD reduces BP in humans. METHODS. Nine healthy male volunteers were given 600 mg of CBD or placebo in a randomized, placebo-controlled, double-blind, crossover study. Cardiovascular parameters were monitored using [...]

Doi : 10.1111/bph.13368 BACKGROUND AND PURPOSE In vivo and in vitro studies have demonstrated a protective effect of cannabidiol (CBD) in reducing infarct size in stroke models and against epithelial barrier damage in numerous disease models. We aimed to investigate whether CBD also affects blood–brain barrier (BBB) permeability following ischaemia. EXPERIMENTAL APPROACH Human brain microvascular endothelial cell (HBMEC) and human astrocyte co-cultures modelled the BBB. Ischaemia was modelled by oxygen–glucose deprivation (OGD) [...]

For this reason, CBD has become a primary focus of medicinal cannabis studies. CBD has been found to have a wide range of benefits, including lowering blood sugar levels, promoting bone growth, and importantly, protecting the human brain and nervous system from degeneration. How CBD Protects the Nervous System The nervous system is comprised of two main parts: the peripheral nervous system, which includes the nerves and ganglia on [...]

LSD was used in the treatment of anxiety, depression, psychosomatic diseases and addiction. However, most of the studies were not performed under contemporary standards, and it has taken several decades for a resurgence of interest in LSD research and [...]

Psychedelics are distinctive from other psychoactive drugs in that they alter the mind, whereas opiates or stimulants alter the mood (Meyer & Quenzer, 2013). Psychedelics affect nature of consciousness itself and access otherwise unknown states of consciousness, as opposed to affecting the degree or extent of one's consciousness and inducing proverbial moods such as [...]

Or la recherche scientifique ne dispose pas de données fiables sur les véritables effets de cette substance, ni sur ses risques potentiels. Ursina s’est longtemps refusée à la tentation d’accompagner ses nuits festives de substances chimiques. «J’avais peur du mauvais trip», dit la Zurichoise de 40 ans, casquette et bomber satiné. Jusqu’à ce qu’elle entende parler du LSD en microdose. Elle se procure l’hallucinogène une première fois il y [...]
