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

by Michael Pollan

“Bad trips” are very real and can be one of “the most challenging experiences of [a] lifetime,” according to a large survey of psychedelic users asked about their experiences.* But it’s important to distinguish what can happen when these drugs are used in uncontrolled situations, without attention to set and setting, from what happens under clinical conditions, after careful screening and under supervision. Since the revival of sanctioned psychedelic research beginning in the 1990s, nearly a thousand volunteers have been dosed, and not a single serious adverse event has been reported.

William James,

Hofmann must somehow have absorbed a bit of the chemical through his skin, because he “was interrupted in my work by unusual sensations.” Hofmann went home, lay down on a couch, and “in a dreamlike state, with eyes closed . . . I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colors.” Thus unfolds the world’s first LSD trip, in neutral Switzerland during the darkest days of World War II. It is also the only LSD trip ever taken that was entirely innocent of expectation.

this would have definitely been an interesting experience, being void of expectations. our lack of knowledge of the neurosciences (at the tume) would've also made it interesting

Intrigued, Hofmann decided a few days later to conduct an experiment on himself—not an uncommon practice at the time. Proceeding with what he thought was extreme caution, he ingested 0.25 milligrams—a milligram is one-thousandth of a gram—of LSD dissolved in a glass of water. This would represent a minuscule dose of any other drug, but LSD, it turns out, is one of the most potent psychoactive compounds ever discovered, active at doses measured in micrograms—that is, one thousandth of a milligram. This surprising fact would soon inspire scientists to look for, and eventually find, the brain receptors and the endogenous chemical—serotonin—that activates them like a key in a lock, as a way to explain how such a small number of molecules could have such a profound effect on the mind. In this and other ways, Hofmann’s discovery helped to launch modern brain science in the 1950s.

The way of the scientist! I love it.
