I see the appeal of microdosing, but to me it renders similar to the kick you might get out of rebelliously sipping a pocket-flask at work. You get the mental boost of "letting loose" while impaired just below the radar.
Microdoses of psychedelics are not impairing. On the contrary, they can improve performance, especially in abstract problem solving.
Also, I've experienced about 40 different psychoactive drugs, including both micro and megadoses of psychedelics. And my experience tracks with GP in that it does cognitively impair you. Maybe don't make blanket statements about people you disagree with, it doesn't make your argument look any stronger.
But I’d say 99% chance no. I’d know the difference.
This is obviously talking about doses closer to mega dose than micro dose. Although as time went on, even small doses that wouldn’t get me much of a buzz would still ruin me for weeks afterwards.
I agree there's really no meaningful concept of "general impairment" unless you're talking about something more extreme like a brain disorder or heavy alcohol intoxication with global involvement leading to something like a coma or gross movement disorder.
These various neuropsych tests try to test something as specific as possible. Working memory for instance. Their development is a complicated field all on its own. And this is psychology, so it's good to keep the reproducibility crisis in mind and adjust one's credences accordingly.
There's a really cool painter whose name I forget who mainly does self portraits while under the effect of various substances. The one where he huffed computer duster for instance,is just a few meaningless lines on a mostly white canvas. That's a pretty good example of global impairment right there. And there's also sorts of paintings on psychedelics, showing varying degrees of visual impairment. Really recommend googling the guy if you want a very visceral way of visualising the various impairments brought on by psychoactive drugs.
This is becoming an unfocused rant so I'll cap it off here I guess.
That is insane
How is your brain not fried
I jest, but mostly I took reasonable precautions and stuck to things I was reasonably sure weren't harmful, or at least toxic. I've had some very bad times with the synthetic cannabinoid, though, and I don't wanna go into it other than to say: I was hella lucky not to have my brain fried. Happy to say I've gained a healthier relationship to drugs since then.
