Yakugaku Zasshi October 1, 2008 Nahoko Uchiyama, Ruri Kikura-Hanajiri, Nobuo Kawahara et al. 46 citations

Many psychotropic substances are easily available in Japan via the Internet, thus the spread of drug abuse is becoming more serious problem. To avoid drug abuse, 32 substances have been controlled in Japan since April in 2007 by the Pharmaceutical Affairs Law as designated substances (Shitei-Yakubutsu, classified as 11 tryptamines, 11 phenethylamines, 2 piperazines, 6 alkyl nitrites, 1...

Phylogenetic relationship of psychoactive fungi based on rRNA gene for a large subunit and their identification using the TaqMan assay (II).

Forensic Science International November 10, 2006 Takuro Maruyama, Nobuo Kawahara, Kazumasa Yokoyama et al.

"Magic mushroom (MM)" is the name most commonly given to psychoactive fungi containing the hallucinogenic components: psilocin (1) and psilocybin (2). We investigated the rRNA gene (internal transcribed spacer (ITS) and large subunit (LSU)) of two Panaeolus species and four Psilocybe species fungi (of these, two are non-psilocybin species). On the basis of sequence alignment, we improved the...

[DNA and chemical analyses of commercial fly agaric-related products].

Shokuhin eiseigaku zasshi. Journal of the Food Hygienic Society of Japan April 1, 2005 Takuro Maruyama, Nobuo Kawahara, Toshimitsu Fukiharu et al.

Since June 6, 2002, psilocin and psilocybin-containing fungi (commonly called "magic mushrooms") have been regulated by the Narcotics and Psychotropics Control Law in Japan. However, various fly agaric-related products are now entering the Japanese market via the internet. In this study, fly agaric-related products available in this way were investigated for raw materials by DNA analysis and...

Discrimination of Psychoactive Fungi (Commonly Called "Magic Mushrooms") Based on the DNA Sequence of the Internal Transcribed Spacer Region.

Food Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi) 2003 Takuro Maruyama, Osamu Shirota, Nobuo Kawahara et al. 14 citations

'Magic mushrooms' (MMs) are psychoactive fungi containing the hallucinogenic compounds, psilocin (1) and psilocybin (2). Since June 6, 2002, these fungi have been regulated by the Narcotics and Psychotropics Control Law in Japan. Because there are many kinds of MMs and they are sold even as dry powders in local markets, it is very difficult to identify the original species of the MMs by...
