Read the study protocol, it was self blinding and it past the review board because the participants were planning to microdose anyway. It devised a so-called self-blinding process, in which participants filled opaque capsules with drugs or a placebo. The capsules were then placed in envelopes with a QR code and shuffled, meaning researchers could later track what participants had taken, while they themselves could not.
