Is the psychedelic hype bubble about to burst? Might that be best for the field? In a new @JAMAPsych article w/ me, @jpotash1, & R. Griffiths, we argue for moving beyond overly negative AND positive extremes to embrace the actual evidence @JHPsychedelics jamanetwork.com/journals/jamap…

For those interested in the history of psychedelic research… I wrote a narrative piece describing studies of psychedelic effects on serotonergic neurons in the dorsal raphe, from late 1960s to 1980s: journals.sagepub.com/doi/10.1177/28…

I haven't read through carefully yet, but some of the best science is accompanied by statements in the form of "y'all thought it might be a certain way, so .... we checked." Very much looking forward to reading this :) Thanks for checking, @TheBorisLab

@Lotus_Solus Wonderful! And great to hear re the translation. I see my book as ideal for an undergrad just starting their studies in psych and neuro and interested in the science of altered states of consciousness

@ExistWell Your book took me right back to my early teens, when I was reading Chalmers' "The Conscious Mind" and Norletlanders' "The User Illusion". I think the second part is really interesting IMO, and the translation is beautiful.

買いました📖読み始めたばかりだけど、すでにおもしろい。 日本でサイケデリクス研究に関わる人や興味がある人には必読の1冊ですね。 色々な分野の人がこの本を読むだろうし、結果その方々がサイケデリクスを知るきっかけになる点でも素晴らしい。

There are no words.

#Artemis II, the first crewed lunar mission in 50+ years, offers a new perspective from the far side of the #moon. Seeing Earth from space can spark the overview effect—a profound sense of awe + connection. Explore the psychology of space travel bit.ly/4sr1Ji2 @ExistWell

🍄 Our second installment of sypres.io, a living systematic review and meta-analysis on MDMA for PTSD is now live on medRxiv. Here's what we found and how we built upon our open science infrastructure to support it 🧵 medrxiv.org/content/10.648…

My book just came out in a Japanese translation. I’d be happy to speak to any classes or groups who happen to read it-

Hello, Moon. It’s great to be back. Here’s a taste of what the Artemis II astronauts photographed during their flight around the Moon. Check out more photos from the mission: nasa.gov/artemis-ii-mul…

Grateful 2b involved in this important work. Props to @MGirnNeuro and @danilobzdok for leading! Hoping that folks read carefully and critically: notably, substantial between-drug differences challenge the primacy of "THE" psychedelic experience

Approaching the near side of the Moon. The Artemis II astronauts have surpassed the record for the distance from Earth at 1:56 ET (1756 UTC). This record was previously set during the Apollo 13 mission when the astronauts traveled 248,655 miles from Earth. The Moon continues to grow larger and larger in the windows of the Orion spacecraft as the Artemis II mission gears up to observe the far side. The astronauts are predicted to make their closest approach of the Moon around 7:02pm ET (2302 UTC).

@venusjupiterleo Thank you! It is more academic than those other books but I think still relatively readable-

@ExistWell That is why I feel your book is also incredibly valuable

面白そう！William Jamesの書籍を連想させる。SpiritualityとScience！ Andrew Newbergも著者にいる。 このDavid B. Yadenさんて臨死体験も研究してなかったけ？別人かな？ 神秘的経験、ヌミノーゼ、サイエンス、プラグマティズム､､､､､､面白そう！ ドキドキする！

@Lotus_Solus Please do!

@ExistWell That would be me, and unfortunately no one else in here Japan doing that kind of work. May I send you an email?

おおおお！サイケデリクス関連の論文で何度もお名前を拝見したYaden先生の著者が日本語で！？絶対に買う！

@h_okumura もしお読みになったら、ぜひご感想をお聞かせください。

@ExistWell ありがとうございます。ぜひ読みたいです

昔流行ったコリン・ウィルソン『オカルト』の現代版か？

@Josh__Hardman The translation feature on here is really cool too. Does psychedelic alpha go out in other languages?

@ExistWell So cool!!!

@Lotus_Solus ありがとうございます！これらの学術論文の翻訳に関心を持ちそうな日本の科学者や研究者をご存じでしょうか。

@ExistWell I've just bought it! Your papers are very fascinating. Especially 'The subjective effects of psychedelics are necessary for their enduring therapeutic effects' is insightful. Btw, I'm hoping to use the Awe Scale and translate the Psychedelic Integration Scale in my next project.
