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 [...]

ABSTRACT Magic mushrooms are rich in the active compound psilocybin, whose activity on consciousness deeply alters cognitive functions, can promote spiritual/mystical experiences and has high biomedical and psychotherapeutic importance. Twenty-eight participants underwent a magic mushroom experience after consuming dehydrated Psilocybe cubensis mushrooms at the dosage of 55.6 mg/Kg (350 μg/kg of psilocybin).

ABSTRACT Some investigations conducted with psilocybin and mushrooms of the Psilocybe genus on the human mind point to a peculiarity of these substances to promote a special state of consciousness. The present study measured the effects of dehydrated magic mushrooms on human visual processes and memory utilizing tasks in a pre- and post-test form. We observed defi cits in visual working memory and these results were consistent with other, recent psilocybin studies. However this and other visual mechanisms [...]

Cavnar (eds.) : "The Therapeutic Use of Ayahuasca", Springer-Verlag Berlin Heidelberg 2014 Doi : 10.1007/978-3-642-40426-9_1 Abstract : Therapeutic applications of the psychedelics or hallucinogens found cross-culturally involve treatment of a variety of physical, psychological, and social maladies.

Wasson Claude Lévi-Strauss L'Homme, 1970, 10-1, pp. 5-16 On sait que les hymnes du RgVeda font une place considérable à une plante enivrante, le Soma, dont le suc exprimé et filtré, puis coupé de lait frais ou caillé, était consommé par les prêtres au cours du rituel et principalement, semble-t-il, par ceux chargés d'incarner le dieu Indra et son cocher Vâyu.
