LSD microdosing is rated here very highly, but it may be not working at all: "Some early experimental studies with LSD suggested that doses of LSD too small to cause any noticeable effects may improve mood and creativity. Prompted by recent discussion of this claim and the purely anecdotal subsequent evidence for it, I decided to run a well-powered randomized blind trial of 3-day LSD microdoses from September 2012 to March 2013. No beneficial effects reached statistical-significance and there were worrisome negative trends. LSD microdosing did not help me." from https://www.gwern.net/LSD%20microdosing https://www.gwern.net/LSD%20microdosing Sure, it is possible that personal responses vary. But unless people do some blind trails, I am very skeptical of the claims (various placebo effects when acting _and_ grading).
