Abstract in brief

  • The study explores whether it is possible to experience psychedelic effects from a placebo in a naturalistic setting, such as a party with music and visual stimuli, by examining individual responses to a placebo described as psilocybin.
  • Results showed significant individual variation, with some participants experiencing effects comparable to moderate or high doses of psychedelics, while others reported no effects, highlighting the influence of expectations and context.
  • Understanding how environmental factors and expectations can produce psychedelic-like experiences without drugs can help researchers better differentiate true drug effects and improve therapeutic practices.

2/5 This paper (linked below) notwithstanding, I wonder how much it even makes sense to even try to separate out drug effects from placebo responding, especially when psychedelics may directly act on moderating the strength of expectations. https://t.co/ThNdoATXzb

@hilaryagro luckily there’s a much safer and faster way to ‘get high’. https://t.co/WfJkvDB2hY I don’t understand why you can’t just buy box of placebo pills at the pharmacy. Even when you know it’s a placebo it works. I’d love to have a drug at home for those meh times.
