Lire la suiteTexas Peyote Culture Kevin FEENEY Cactus and Succulent Journal, 2018, 90, (1), 29-38 Peyote (Lophophora williamsii (Lem.) Coult.) has deep roots in Texas, or a deep taproot to be precise. While Texas is currently home to a federally regulated peyote trade, where members of the Native American Church (NAC) can legally purchase peyote for use in religious ceremonies, archaeological sites in Texas, and neighboring Coahuila, also mark the earliest known ceremonial associations between humans and peyote. It is believed that the peyote rituals of the Huichol, Nahua, Tarahumara, Cora, Tepehuan, and more recently the NAC, all trace their origins to the peyote gardens [...]

J. Nutt Psychological Medicine, 2016, 46, 1379–1390. doi:10.1017/S0033291715002901 Background : Lysergic acid diethylamide (LSD) is a potent serotonergic hallucinogen or psychedelic that modulates consciousness in a marked and novel way. This study sought to examine the acute and mid-term psychological effects of LSD in a controlled study. Method : A total of 20 healthy volunteers participated in this within-subjects study. Participants received LSD (75 μg, intravenously) on one occasion and placebo (saline, intravenously) on another, in a [...]

KALUEFF Trends in Pharmacological Sciences, 2017, 38, (1), 992-1005 https://doi.org/10.1016/j.tips.2017.08.003 Trends Psychedelic drugs profoundly alter human behavior, acting primarily via agonism at the 5-HT2A receptor in the brain. Research into the mechanisms of psychedelic drugs is experiencing a renaissance after years of stagnation. Animal models show that psychedelic drugs alter a number of crucial molecular mechanisms. Psychedelic drugs cause widespread changes in cognition and brain connectivity. Recent pilot studies show LSD and psilocybin are effective in treating psychiatric disorders and possibly other illnesses. Psychedelic biomedicine is rapidly emerging as an important area [...]
Lire la suiteRole of the Serotonin 5-HT2A Receptor in Learning John A. Harvey Learning & Memory, 2003, 355-362 www.learnmem.org http://www.learnmem.org/cgi/doi/10.1101/lm.60803. This study reviews the role of the serotonin 5-HT2A receptor in learning as measured by the acquisition of the rabbit’s classically conditioning nictitating membrane response, a component of the eyeblink response. Agonists at the 5-HT2A receptor including LSD (d-lysergic acid diethylamide) enhanced associative learning at doses that produce cognitive effects in humans. Some antagonists such as BOL (d-bromolysergic acid diethylamide), LY53,857, and ketanserin acted as neutral antagonists in that they had no effect on learning, whereas others (MDL11,939, ritanserin, and mianserin) acted as inverse agonists in that [...]

Griffiths Neurotherapeutics, 2017, 14, 734–740 DOI 10.1007/s13311-017-0542-y Abstract Psilocybin and other 5-hydroxytryptamine2A agonist classic psychedelics have been used for centuries as sacraments within indigenous cultures. In the mid-twentieth century they were a focus within psychiatry as both probes of brain function and experimental therapeutics. By the late 1960s and early 1970s these scientific inquires fell out of favor because classic psychedelics were being used outside of medical research and in association with the emerging counter culture. However, in the twenty-first century, scientific interest in classic psychedelics has returned and grown as a result of [...]
Lire la suiteLe cannabis thérapeutique expérimenté 2 ans à partir de 2020 Par Public Sénat avec l'AFP Vendredi 12 juillet 2019 à 16:06 L’Agence du médicament a donné, jeudi, son accord à une expérimentation du cannabis thérapeutique. Sous l’impulsion d’Esther Benbassa, un débat sur la question avait eu lieu au mois de mai dans l’hémicycle. La sénatrice écologiste se réjouit de cette expérimentation mais regrette la « frilosité » du cadre. Fin 2018, l’Agence du médicament (ANSM) avait mandaté un comité d’experts (CSST) pour lui fournir un projet-cadre d’expérimentation du cannabis thérapeutique. Jeudi, l’ANSM a donc donné son feu vert aux conditions d’une expérimentation qui démarrera [...]

Their activity is mediated through various targets that include cannabinoid receptors or transient receptor potential vanilloid (TRPV)1. Synthesis and degradation of NADA are not yet fully understood. Nonetheless, there is evidence that NADA plays an important role in nociception and inflammation in the central and peripheral nervous system. The TRPV1 receptor, for which NADA is a [...]
