"Decriminalisation has been a very popular approach at the local level," Marks says. "There are about two dozen cities across the country that have decriminalised to one extent or another." In Germany, ibogaine is unregulated, except for pharmaceutical rules under the German Medicinal Products Act. Ayahuasca is also legal in Peru, which in 2008, designated the psychedelic a part of Indigenous heritage. In these areas, ibogaine generally lacks a legal framework regulating it.

Most of the athletes drifted off to be alone so they could scribble down their thoughts in a journal, per instructions from Wake staffers. Two hours into the ceremony, after the psychedelic had kicked in, whatever was taking place was occurring inside the athletes' heads. A HUM OF NERVOUS tension lingered in the air as the athletes prepared for the ceremony. The attendees milled about, checking in with Wake's medical personnel to offer their blood and saliva samples. Some participated in a yoga class in an outdoor studio that overlooked the jungle.

Eighty one species of Psilocybe have genome sequence data available, including Psi. Is largely based morphologically (Maruyama et al., 2006; Ramírez-Cruz et al., 2013b; Borovička et al., 2015). Three classifications have been proposed for the division of Psilocybe into subgenera (Guzmán, Mexican Cubensis Chocolate Bar 1978; Singer, 1986; Noordeloos, 2011). Psilocybe was divided into 16 subgenera by Guzmán (1978), according to the form and structure of fruiting bodies, form and wall thickness of the spores, and absence or presence of pleuro- and cheilocystidia.

Global interest in the psychoactive properties of magic mushrooms is significant at present. There are an estimated 20–30 species of magic mushrooms in Australia, some of which are native, and some of which have been introduced and then flourished in disturbed ecosystems. UQ's Dr Alistair McTaggart will begin curation of Australia’s first living (and legal) culture collection capturing the biodiversity of magic mushrooms native to Australia. That said, Volkow and Siegel are concerned about the growing number of people using psilocybin, whether it is recreationally or a form of self-medication for mental health symptoms.
