    Sex, Psychedelics and Consent (Pt. 2)

    Allegations of sexual, financial, and psychological abuse sometimes arise in the growing psychedelic church movement in Utah and beyond. A leader or guide might use their authority to pressure people – usually women – into having sexual contact with them. How might mind-altering substances play into such abuses of power? How should practitioners navigate consent? And what can psychedelic churches do to keep people safe?

    Psychedelic Church vs. State of Utah (Pt. 1)

    In November 2024, police raided Singularism, an establishment that claims to be a new religion founded by a former Mormon man. But before the state could press charges, Singularism went on the offensive, saying the seized psilocybin was a religious sacrament. Singularism sued the state of Utah, claiming religious freedom. So far, a federal judge has been adamant: psychedelic religion is still religion.

    Psychedelics for Anorexia?

    In South Africa, a former ballet dancer and horseback rider struggled for years with anorexia. After undergoing in-patient treatment and regular therapy, she tried psychedelics, and that’s when she got her first meaningful glimpse into what her mind would be like without anorexia. So is this actually a potential treatment? Early research suggests it could be. And now, at the University of California, San Francisco a new study is underway, exploring whether psilocybin might help young adults with severe anorexia.

    Mice on Magic Mushrooms

    How do you know if a mouse is on a psychedelic? It might just shake its head. This behavior, known as the head-twitch response, signals whether a molecule is a psychedelic-like hallucinogen. Head twitch is one tool used by pharmaceutical companies racing to develop new mental health drugs. But does a mouse experience an altered state like a human? Do animals have mystical experiences? And what can we really learn about the brain, or even human consciousness, from these unwitting rodent psychonauts?

    UPDATE: A Navy SEAL Goes to Mexico to take Ibogaine

    A former Navy SEAL named Craig deployed nine times over nearly three decades in the military. When he left the service, he felt lucky to have all his limbs, toes and fingers. But he found himself struggling with language and memory and rising frustration. One day he forgot his wife’s name and couldn’t remember it for hours. His wife Gretchen started looking for help online and found information about a Stanford University research study on ibogaine and veterans. Craig volunteered. On October 8, Dr. Nolan Williams, who led that ibogaine study, died. He was 42.

    Was Ayahuasca Used for Political Indoctrination in Brazil?

    In 2023, supporters of Brazil’s former president Jair Bolsonaro violently stormed the capital in an attempted coup. Among Bolsonaro’s most loyal supporters were leaders in the União do Vegetal, one of Brazil’s oldest and most popular ayahuasca churches. Brazil’s laws state that electoral propaganda is forbidden inside temples and churches but former União do Vegetal members say they experienced what some called brainwashing while in an altered state.

    Was it DMT? Or was it heaven?

    When a neurosurgeon claimed he glimpsed the afterlife during a coma, skeptics offered a more earthly interpretation – a surge of DMT produced by his own body. Was his tale of eternity a trick of the brain, or a window into something science can’t explain?

    The Psychedelic Playlist

    Vivaldi. Bach. The Beatles. The Johns Hopkins playlist has been the standard soundtrack in psychedelic trials at Johns Hopkins and therapy rooms around the world for more than 25 years. It also skews toward Classical and Christian music. When Sughra Ahmed, a Muslim, enrolled in a psilocybin study that used this playlist, she didn’t love what she heard. So where did this playlist come from exactly? And what can science tell us about what role music plays in a trip?

    A Priest, a Rabbi, and a Muslim Leader Get High

Now, the long-awaited results of the study are out. Journalist Michael Pollan, who wrote about the research for The New Yorker, weighs in on whether science can ever truly measure mysticism.
