“Microdosing” psychedelic drugs involves regularly taking amounts so tiny that they don’t impair a person’s normal functioning, but — it’s claimed — subtly enhance wellbeing, concentration and creativity. In May, for example, the Digest reported on a study that found hints of reduced stress and increased emotional intensity among people who microdosed LSD and psilocybin, from ‘magic’ mushrooms.

However, we also stressed that there has been little research into the technique — and now a review of the field published in the Journal of Psychopharmacology concludes that while the popularity of microdosing has exploded over the past eight years, knowledge about what it actually does remains patchy and anecdotal. In fact, there are still far more questions about the technique than answers, write Kim Kuypers at Maastricht University, and her colleagues.
