"Does microdosing work? In short, the jury is still out. Some studiesindicate a very real and significant benefit from microdosing, whereasothers are much less convincing and show little to no benefit. One recent studyused a naturalistic, observational design to study 953 psilocybinmicrodosers compared with 180 nondosing participants for 30 days, andfound "small to medium-sized improvements in mood and mental health thatwere generally consistent across gender, age, and presence of mentalhealth concerns." This study and others like it appear to confirm many anecdotal reports of people who swear by the benefits they have experienced from microdosing." (Taken from https://www.health.harvard.edu/blog/the-popularity-of-microdosing-of-psychedelics-what-does-the-science-say-202209192819) There isnt a definitive answer on it due to legal bars but you can look up any number of videos or articles about it having positive benefits. As for the tolerance... you're taking a very small amount and the treatment (I think, do not hold me on this) is every 2-3 weeks? It's recommended that you space out psilocybin trips (taking a normal tripping dose 1.5-3g) to atleast once a week/ every 2 weeks for the full effect.

Can't really tell someone that something doesn't work if it works for that person.

You're hearing alot more about micro-dosing for the benefits it has against Addiction and Depression. Certainly seems like a better alternative to some of the "remedies".
