This certainly doesn't seem at all like a scientist's work to me, and in fact is the kind of moralising that leads me to wonder - what can be the values of the person who wrote it?
I mean, the public has been exposed to a number of other mass psychological experiments in the time frame I think the author is referencing, social media and its hooks into our reward centres being the most notable for being both more pervasive and more ingrained into day-to-day life
I'm not saying the author is wrong on all accounts (though I also think psychedelics such as MDMA and Ketamine have shown much more promise for PTSD and depression than the other pharmaceutical treatments for those disorders which were integrated into the social fabric for decades before psychedelics became "popular")
But the suggestion that the decay of civilization has been caused by the uptick in availability of psychedelic treatments has as much evidence as "wet streets cause rain" or "economic growth causes traffic congestion"
Do I think that microdosing is well supported? No. Do I think that the author added anything to the discussion beyond their obvious love for the sound of their own voice? No.

For example.
Psychedelics are one of the many joys of being alive on this earth. This post is noise and should probably get flagged.
