Performance-enhancing drugs have always typically been regarded as caffeine, amphetamines and cocaine. But, now psychedelics? Microdoses of the psychedelic drug are also becoming a creativity booster for professionals.

Rolling Stone goes into the mind of “Ken,” a 25 year-old with a master’s degree from Stanford who works at a tech startup in San Francisco. Ken does a little bit of everything, from hardware and software design to sales and business development, and he recently discovered a new way to enhance his productivity and creativity at work.

Ken is one of the growing number of professionals who are microdosing with LSD in their free time, and occasionally, at the office. A microdose is about a tenth of a normal dose—around 10 micrograms of LSD or 0.2-0.5 grams of mushrooms.

“I had an epic time,” Ken explained at the end of a psychedelic-enhanced day. “I was making a lot of sales, talking to a lot of people, finding solutions to their technical problems.” According to Rick Doblin, founder and exective director of the Multidisciplinary Association for Psychedelic Studies (MAPS), a microdose is just enough “to feel a little bit of energy lift, a little bit of insight, but not so much that you are tripping.”

Microdosing was introduced by James Fadiman, author of the Psychedelic Explorer’s Guide, at a conference on psychedelic research in 2011. He claims that the number of people curious of microdosing has been growing ever since, especially from San Francisco, where the typical individual is an “übersmart twentysomething” curious to see whether it will help them succeed in the office.

“It’s an extremely healthy alternative to Adderall,” Fadiman explained. He recommends microdosing every fourth day, by taking the drug in the morning and sticking to a typical daily routine. His correspondents have told him that regular microdosing has also alleviated disorders such as depression, migraines and chronic-fatigue syndrome.
