Acute and post-acute behavioral and psychological effects of salvinorin A in humans Peter H. Addy Psychopharmacology, 2012, 220, 195–204 DOI 10.1007/s00213-011-2470-6 Abstract Rationale : Salvia divinorum has been used for centuries, and nontraditional use in modern societies is increasing. Inebriation and aftereffects of use are poorly documented in the scientific literature. Objectives : This double-blind, placebo-controlled, randomized study analyzed subjective experiences of salvinorin A (SA) inebriation and consequences of use after 8 weeks. Methods : Thirty middle-aged, well-educated, hallucinogenexperienced participants smoked either 1,017 or 100μg SA 2 weeks apart in counterbalanced order. Vital signs were recorded before and after inhalation. A researcher rated participants' behavior during sessions. [...]

Griffiths Journal of Psychopharmacology, 2008, 22, 603–620. doi : 10.1177/0269881108093587 Abstract There has recently been a renewal of human research with classical hallucinogens (psychedelics). This paper first briefly discusses the unique history of human hallucinogen research, and then reviews the risks of hallucinogen administration and safeguards for minimizing these risks. Although hallucinogens are relatively safe physiologically and are not considered drugs of dependence, their administration involves unique psychological risks. The most likely risk is overwhelming distress during drug action ('bad trip'), which could lead to potentially dangerous behaviour such as [...]

This stall in innovation has also been linked with intense debates on the current diagnostics and explanations for mental disorders, together constituting a paradigmatic crisis. A radical innovation is psychedelic-assisted psychotherapy (PAP): professionally supervised use of ketamine, MDMA, psilocybin, LSD and ibogaine as part of elaborated psychotherapy programs. Clinical results so far have shown safety and efficacy, even for “treatment resistant” conditions, and thus deserve increasing attention [...]

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 [...]
Lire la suiteLegally high ? Legal considerations of Salvia divinorum O. Hayden GRIFFIN III, Bryan Lee MILLER, David N. KHEYS Journal of Psychoactive Drugs, 2008, 40, (2), 183-190 In the past few years, there has been an apparent increase in the recreational use of Salvia divinorum. Its origins lie in the Mazatecan culture where its ceremonial use had historic ties to the traditional mystic religion and medicine practiced by its people. This psychoactive plant is native to the forest ravines of Oaxaca, Mexico--the area inhabited by the Mazatecs. It is a relative in the mint family, a family of plants that includes several psychoactive species. [...]

Krebs, Pal-Ørjan Johansen PLoS ONE, 2013, 8, (8): e63972. doi:10.1371/journal.pone.0063972 Abstract Background : The classical serotonergic psychedelics LSD, psilocybin, mescaline are not known to cause brain damage and are regarded as non-addictive. Clinical studies do not suggest that psychedelics cause long-term mental health problems. Psychedelics have been used in the Americas for thousands of years. Over 30 million people currently living in the US have used LSD, psilocybin, or mescaline. Objective : To evaluate the association between the lifetime use of psychedelics and current mental health in the adult population. Method : Data drawn from years 2001 [...]

De Smet, Olof Beck, G¨oran Possnert, Jan G. Bruhn Journal of Ethnopharmacology, 2005, 101, 238–242 doi:10.1016/j.jep.2005.04.022 Abstract Two archaeological specimens of peyote buttons, i.e. dried tops of the cactus Lophophora williamsii (Lem.) Coulter, from the collection of theWitte Museum in San Antonio, was subjected to radiocarbon dating and alkaloid analysis. The samples were presumably found in Shumla Cave No. 5 on the Rio Grande, Texas. Radiocarbon dating shows that the calibrated 14C age of the weighted mean of the two individual dated samples corresponds to [...]
