Psilocybin was the most popular, followed (surprisingly) by Amanita muscaria, then MDMA, then LSD.
That means 3.7% of the American population has microdosed. If you ask me, we have to up those numbers, and those dosages... it's not a bad start, but I'm worried that it's a way to cheapen the psychedelic experience, lending it to "enhancing productivity" instead of rewiring your psyche and breaking down social constructs.
If it helps people, it can't be a bad thing. I just hope it doesn't stop at "micro" for most people.
