How to Change Your Mind: What the New Science of Psychedelics Teaches Us About Consciousness, Dying, Addiction, Depression, and Transcendence

by Michael Pollan

over time, we tend to optimize and conventionalize our responses to whatever life brings. Each of us develops our shorthand ways of slotting and processing everyday experiences and solving problems, and while this is no doubt adaptive—it helps us get the job done with a minimum of fuss—eventually it becomes rote. It dulls us. The muscles of attention atrophy.

The efficiencies of the adult mind, useful as they are, blind us to the present moment. We’re constantly jumping ahead to the next thing. We approach experience much as an artificial intelligence (AI) program does, with our brains continually translating the data of the present into the terms of the past, reaching back in time for the relevant experience, and then using that to make its best guess as to how to predict and navigate the future.

A final word on nomenclature. The class of molecules to which psilocybin and LSD (and mescaline, DMT, and a handful of others) belong has been called by many names in the decades since they have come to our attention. Initially, they were called hallucinogens. But they do so many other things (and in fact full-blown hallucinations are fairly uncommon) that researchers soon went looking for more precise and comprehensive terms, a quest chronicled in chapter three. The term “psychedelics,” which I will mainly use here, does have its downside. Embraced in the 1960s, the term carries a lot of countercultural baggage.

Hoping to escape those associations and underscore the spiritual dimensions of these drugs, some researchers have proposed they instead be called “entheogens”—from the Greek for “the divine within.” This strikes me as too emphatic. Despite the 1960s trappings, the term “psychedelic,” coined in 1956, is etymologically accurate. Drawn from the Greek, it means simply “mind manifesting,” which is precisely what these extraordinary molecules hold the power to do.

Once the acute effects wore off, Hofmann felt the “afterglow” that frequently follows a psychedelic experience, the exact opposite of a hangover. When he walked out into his garden after a spring rain, “everything glistened and sparkled in a fresh light. The world was as if newly created.”

Of the two, Rick Doblin has been at it longer and is by far the more well known. Doblin founded the Multidisciplinary Association for Psychedelic Studies (MAPS) all the way back in the dark days of 1986—the year after MDMA was made illegal and a time when most wiser heads were convinced that restarting research into psychedelics was a cause beyond hopeless. Doblin, born in 1953, is a great shaggy dog with a bone; he has been lobbying to change the government’s mind about psychedelics since shortly after graduating from New College, in Florida, in 1987. After experimenting with LSD as an undergraduate, and later with MDMA, Doblin decided his calling in life was to become a psychedelic therapist. But after the banning of MDMA in 1985, that dream became unachievable without a change in federal laws and regulations, so he decided he’d better first get a doctorate in public policy at Harvard’s Kennedy School. There, he mastered the intricacies of the FDA’s drug approval process, and in his dissertation plotted the laborious path to official acceptance that psilocybin and MDMA are now following.
